A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust.
Specific sites or molecular structures on cell membranes or in cells with which phencyclidine reacts or to which it binds to elicit the specific response of the cell to phencyclidine. Studies have demonstrated the presence of multiple receptor sites for PCP. These are the PCP/sigma site, which binds both PCP and psychotomimetic opiates but not certain antipsychotics, and the PCP site, which selectively binds PCP analogs.
The misuse of phencyclidine with associated psychological symptoms and impairment in social or occupational functioning.
Drugs capable of inducing illusions, hallucinations, delusions, paranoid ideations, and other alterations of mood and thinking. Despite the name, the feature that distinguishes these agents from other classes of drugs is their capacity to induce states of altered perception, thought, and feeling that are not experienced otherwise.
An opioid analgesic with actions and uses similar to MORPHINE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1095)
A potent noncompetitive antagonist of the NMDA receptor (RECEPTORS, N-METHYL-D-ASPARTATE) used mainly as a research tool. The drug has been considered for the wide variety of neurodegenerative conditions or disorders in which NMDA receptors may play an important role. Its use has been primarily limited to animal and tissue experiments because of its psychotropic effects.
Drugs that bind to but do not activate excitatory amino acid receptors, thereby blocking the actions of agonists.
A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.
Venoms produced by frogs, toads, salamanders, etc. The venom glands are usually on the skin of the back and contain cardiotoxic glycosides, cholinolytics, and a number of other bioactive materials, many of which have been characterized. The venoms have been used as arrow poisons and include bufogenin, bufotoxin, bufagin, bufotalin, histrionicotoxins, and pumiliotoxin.
A family of tricyclic hydrocarbons whose members include many of the commonly used tricyclic antidepressants (ANTIDEPRESSIVE AGENTS, TRICYCLIC).
A class of cell surface receptors recognized by its pharmacological profile. Sigma receptors were originally considered to be opioid receptors because they bind certain synthetic opioids. However they also interact with a variety of other psychoactive drugs, and their endogenous ligand is not known (although they can react to certain endogenous steroids). Sigma receptors are found in the immune, endocrine, and nervous systems, and in some peripheral tissues.
The d-form of AMPHETAMINE. It is a central nervous system stimulant and a sympathomimetic. It has also been used in the treatment of narcolepsy and of attention deficit disorders and hyperactivity in children. Dextroamphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulating release of monamines, and inhibiting monoamine oxidase. It is also a drug of abuse and a psychotomimetic.
Cell surface receptors that bind signalling molecules released by neurons and convert these signals into intracellular changes influencing the behavior of cells. Neurotransmitter is used here in its most general sense, including not only messengers that act to regulate ion channels, but also those which act on second messenger systems and those which may act at a distance from their release sites. Included are receptors for neuromodulators, neuroregulators, neuromediators, and neurohumors, whether or not located at synapses.
A phenyl-piperidinyl-butyrophenone that is used primarily to treat SCHIZOPHRENIA and other PSYCHOSES. It is also used in schizoaffective disorder, DELUSIONAL DISORDERS, ballism, and TOURETTE SYNDROME (a drug of choice) and occasionally as adjunctive therapy in INTELLECTUAL DISABILITY and the chorea of HUNTINGTON DISEASE. It is a potent antiemetic and is used in the treatment of intractable HICCUPS. (From AMA Drug Evaluations Annual, 1994, p279)
A class of ionotropic glutamate receptors characterized by affinity for N-methyl-D-aspartate. NMDA receptors have an allosteric binding site for glycine which must be occupied for the channel to open efficiently and a site within the channel itself to which magnesium ions bind in a voltage-dependent manner. The positive voltage dependence of channel conductance and the high permeability of the conducting channel to calcium ions (as well as to monovalent cations) are important in excitotoxicity and neuronal plasticity.
Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus.
A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.

Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.
In about 250 species of electric fishes, modified muscle fibers forming disklike multinucleate plates arranged in stacks like batteries in series and embedded in a gelatinous matrix. A large torpedo ray may have half a million plates. Muscles in different parts of the body may be modified, i.e., the trunk and tail in the electric eel, the hyobranchial apparatus in the electric ray, and extrinsic eye muscles in the stargazers. Powerful electric organs emit pulses in brief bursts several times a second. They serve to stun prey and ward off predators. A large torpedo ray can produce of shock of more than 200 volts, capable of stunning a human. (Storer et al., General Zoology, 6th ed, p672)

Effects of stimulants of abuse on extrapyramidal and limbic neuropeptide Y systems. (1/421)

Neuropeptide Y (NPY), an apparent neuromodulating neuropeptide, has been linked to dopamine systems and dopamine-related psychotic disorders. Because of this association, we determined and compared the effects of psychotomimetic drugs on extrapyramidal and limbic NPY systems. We observed that phencyclidine, methamphetamine (METH), (+)methylenedioxymethamphetamine (MDMA), and cocaine, but not (-)MDMA, similarly reduced the striatal content of NPY-like immunoreactivity from 54% (phencyclidine) to 74% [(+) MDMA] of control. The effects of METH on NPY levels in the nucleus accumbens, caudate nucleus, globus pallidus, and substantia nigra were characterized in greater detail. We observed that METH decreased NPY levels in specific regions of the nucleus accumbens and the caudate, but had no effect on NPY in the globus pallidus or the substantia nigra. The dopamine D1 receptor antagonist SCH-23390 blocked these effects of METH, suggesting that NPY levels throughout the nucleus accumbens and the caudate are regulated through D1 pathways. The D2 receptor antagonist eticlopride did not appear to alter the METH effect, but this was difficult to determine because eticlopride decreased NPY levels by itself. A single dose of METH was sufficient to lower NPY levels, in some, but not all, regions examined. The effects on NPY levels after multiple METH administrations were substantially greater and persisted up to 48 h after treatment; this suggests that synthesis of this neuropeptide may be suppressed even after the drug is gone. These findings suggest that NPY systems may contribute to the D1 receptor-mediated effects of the psychostimulants.  (+info)

The neuropsychopharmacology of phencyclidine: from NMDA receptor hypofunction to the dopamine hypothesis of schizophrenia. (2/421)

Administration of noncompetitive NMDA/glutamate receptor antagonists, such as phencyclidine (PCP) and ketamine, to humans induces a broad range of schizophrenic-like symptomatology, findings that have contributed to a hypoglutamatergic hypothesis of schizophrenia. Moreover, a history of experimental investigations of the effects of these drugs in animals suggests that NMDA receptor antagonists may model some behavioral symptoms of schizophrenia in nonhuman subjects. In this review, the usefulness of PCP administration as a potential animal model of schizophrenia is considered. To support the contention that NMDA receptor antagonist administration represents a viable model of schizophrenia, the behavioral and neurobiological effects of these drugs are discussed, especially with regard to differing profiles following single-dose and long-term exposure. The neurochemical effects of NMDA receptor antagonist administration are argued to support a neurobiological hypothesis of schizophrenia, which includes pathophysiology within several neurotransmitter systems, manifested in behavioral pathology. Future directions for the application of NMDA receptor antagonist models of schizophrenia to preclinical and pathophysiological research are offered.  (+info)

Effects of (+)-HA-966, CGS-19755, phencyclidine, and dizocilpine on repeated acquisition of response chains in pigeons: systemic manipulation of central glycine sites. (3/421)

The effects of i.m. injections of (+)-HA-966, a glycine-site antagonist at the N-methyl-D-aspartate (NMDA) subtype of the glutamate receptor, its enantiomer (-)-HA-966, the competitive glutamate antagonist CGS-19755, the uncompetitive glutamate antagonists phencyclidine and dizocilpine, and the micro opioid agonist morphine were evaluated in a repeated acquisition task in pigeons. All of the drugs produced dose-dependent decreases in rates of responding. The NMDA receptor and channel blockers and (+)-HA-966 appeared to have a greater effect on acquisition than did morphine at doses that did not fully suppress responding. The rate suppression and learning impairment produced by a large dose of (+)-HA-966 (100 mg/kg) were completely prevented by coadministration of the glycine-site agonist D-serine (560 mg/kg) but not by its enantiomer, L-serine (1000 mg/kg). D-Serine, however, produced incomplete antagonism of the effects of dizocilpine and phencyclidine and failed to alter those of CGS-19755. These findings provide evidence that reducing the activity of the NMDA subtype of the glutamate receptor through pharmacological action at any of three sites produces similar decrements in acquisition, and those produced through antagonism of the glycine site are differentially sensitive to the glycine-site agonist D-serine.  (+info)

Clozapine, but not haloperidol, prevents the functional hyperactivity of N-methyl-D-aspartate receptors in rat cortical neurons induced by subchronic administration of phencyclidine. (4/421)

Repeated exposure of rats to the psychotomimetic drug phencyclidine (PCP) markedly increased the response of prefrontal cortical neurons to the glutamate agonist N-methyl-D-aspartate (NMDA) relative to agonist alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid. Moreover, acute challenge by PCP produced a significantly reduced block of NMDA-induced current. In addition, the subchronic administration of PCP reduced significantly the paired-pulse facilitation, accompanied by a significant increase of excitatory postsynaptic current variance. These results suggest that repeated exposure to PCP increased evoked release of excitatory amino acids. The enhanced release of excitatory amino acids evoked by NMDA could explain, at least partly, a hypersensitive response to NMDA and a reduced blockade of the NMDA responses by a PCP challenge in rats exposed repeatedly to PCP. Pretreatment with the atypical antipsychotic drug clozapine, but not the typical antipsychotic drug haloperidol, attenuates the repeated PCP-induced effect. Our results support the hypothesis that clozapine may facilitate NMDA receptor-mediated neurotransmission to improve schizophrenic-negative symptoms and cognitive dysfunction. This novel approach is useful for evaluating the cellular mechanisms of action of atypical antipsychotic drugs.  (+info)

Rat strain differences in the ability to disrupt sensorimotor gating are limited to the dopaminergic system, specific to prepulse inhibition, and unrelated to changes in startle amplitude or nucleus accumbens dopamine receptor sensitivity. (5/421)

Previous studies indicate that a variety of pharmacological agents interfere with the prepulse inhibition of the acoustic startle (PPI) response including phencyclidine (PCP), 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT), amphetamine, and apomorphine. Strain differences have been observed in the ability of apomorphine to disrupt PPI, although the degree to which these strain differences occur after administration of nondopaminergic drugs or the degree to which differences can be observed in other models of dopamine (DA) receptor activation has not been elucidated. The present study tested the effects of apomorphine, amphetamine, 8-OH-DPAT, and PCP on PPI in the Sprague Dawley and Wistar rat strains. Because apomorphine disrupts PPI via activation of DA receptors in the nucleus accumbens, apomorphine-induced hyperlocomotion, also a behavioral model of nucleus accumbens DA receptor activation, was measured in both rat strains. Administration of PCP or 8-OH-DPAT attenuated PPI in both strains, whereas apomorphine and amphetamine only attenuated PPI in Wistar rats. The ability of apomorphine to increase motor activity in the absence of a startle-eliciting stimulus was similar in the two strains, as was apomorphine-induced hyperlocomotion. A time course analysis of the effects of apomorphine on startle response in Sprague Dawley rats found that changes in the magnitude of PPI followed changes in basic startle amplitude. Similarly, no apomorphine-induced attenuation of PPI was observed in Sprague Dawley rats after 6-OHDA-induced DA receptor supersensitivity in the nucleus accumbens. These data suggest a dissociation between the effects of DA receptor agonists in PPI and other behavioral models of DA receptor activation.  (+info)

Effects of sustained phencyclidine exposure on sensorimotor gating of startle in rats. (6/421)

Phencyclidine (PCP), a non-competitive NMDA antagonist with actions at multiple other central nervous system receptors, can cause both acute and lasting psychoses in humans, and has also been used in cross-species models of psychosis. Acute exposure to PCP in rats produces behavioral changes, including a loss of prepulse inhibition (PPI) of the startle reflex, which parallels the loss of PPI observed in schizophrenia patients. Sustained exposure to PCP in rats produces neuropathological changes in several limbic regions and prolonged behavioral abnormalities that may parallel neuropsychological deficits in schizophrenia. It is unclear whether sustained PCP exposure will also produce a loss of prepulse inhibition which parallels the decrease observed in schizophrenia patients. In the present study, we examined changes in PPI during and after sustained PCP administration, using 5-day PCP exposure via subcutaneous osmotic minipumps, or 14-day PCP exposure via repeated intraperitoneal injections. In both forms of drug delivery, PPI was disrupted during, but not after, sustained drug exposure. PPI does not appear to be sensitive to neuropathological effects of sustained PCP exposure.  (+info)

Excitatory actions of NMDA receptor antagonists in rat entorhinal cortex and cultured entorhinal cortical neurons. (7/421)

We have characterized excitatory effects of non-competitive NMDA receptor antagonists MK-801, PCP, and ketamine in the rat entorhinal cortex and in cultured primary entorhinal cortical neurons using expression of immediate early gene c-fos as an indicator. NMDA receptor antagonists produced a strong and dose-dependent increase in c-fos mRNA and protein expression confined to neurons in the layer III of the caudal entorhinal cortex. Induction of c-fos mRNA is delayed and it is inhibited by antipsychotic drugs. Cultured entorhinal neurons are killed by high doses of MK-801 and PCP but c-fos expression is not induced in these neurons indicating that this in vitro model does not fully replicate the in vivo effects of PCP-like drugs in the entorhinal cortex. Excitatory effects of the NMDA receptor antagonists may be connected with the psychotropic side effects of these drugs and might become a useful model system to investigate neurobiology of psychosis.  (+info)

Characterization of interaction of 3,4,5-trimethoxybenzoic acid 8-(diethylamino)octyl ester with Torpedo californica nicotinic acetylcholine receptor and 5-hydroxytryptamine3 receptor. (8/421)

The widely used calcium channel antagonist 3,4,5-trimethoxybenzoic acid 8-(diethylamino)octyl ester (TMB-8) has been identified as a noncompetitive antagonist (NCA) and open-channel blocker of both muscle- and neuronal-type nicotinic acetylcholine receptors (AChRs). To further examine the interaction of TMB-8 with the AChR, the compound was tested as a competitor for the binding of two NCAs of the Torpedo californica AChR, phencyclidine and 3-trifluoromethyl-3-(m[125I]iodophenyl)diazirine, for which the binding to the AChR has been pharmacologically well characterized and a channel binding loci has been established. TMB-8 fully inhibited specific photoincorporation of 3-trifluoromethyl-3-(m[125I]iodophenyl)diazirine into the resting AChR channel (IC50 = 3.1 microM) and inhibited high-affinity [3H]phencyclidine binding to the desensitized AChR (IC50 = 2.4 microM). We conclude that TMB-8 is a potent NCA of the nicotinic AChR, interacting with the resting, open-channel, and desensitized channel conformations. TMB-8 was next tested as an inhibitor of the structurally homologous 5-hydroxytryptamine (5-HT)3 receptor (5-HT3R). Using 5-HT3R containing Sf21 cell membranes, TMB-8 completely inhibited specific binding of the radiolabeled 5-HT3R antagonist [3H]GR65630 (Ki = 2.5 microM). Furthermore, TMB-8 antagonized 5-HT-evoked currents of both mouse and human 5-HT3Rs expressed in Xenopus laevis oocytes, and additional analysis was consistent with a competitive antagonistic mechanism of action. These results, taken together, indicate that TMB-8 antagonizes the function of the AChR and 5-HT3R by different mechanisms. Given the sequence similarity and emerging evidence of structural homology in the channels of these two receptors, these results underscore the existence of subtle yet important structural differences in each channel.  (+info)

N2 - Calcium dependent release of preloaded [3H]-γ-aminobutyric acid (GABA) from mouse striatal and cerebellar slices was investigated after acute and chronic administration of phencyclidine (PCP). Chronic administration of PCP was achieved by osmotic minipumps which delivered PCP at a constant rate. Ca++ dependent GABA release from the cerebellum but not from the striatum of naive mouse was significantly inhibited by the in vitro addition of 1 x 10-4 M PCP. Acute administration of low doses (10 mg/kg) of PCP enhanced CA++ dependent GABA release from the striatum, whereas in high doses (40 mg/kg) a decrease in release was observed. A similar general trend of response was observed when cerebellar slices were used. Continuous administration of PCP (1 mg/kg for 2 ...

Impaired ability to shift perceptual attentional set forms a core feature of schizophrenic illness and is associated with prefrontal cortical dysfunction. A pharmacological model producing equivalent deficits in rodents may enable the development of novel therapeutic strategies for effective treatment of cognitive impairments in schizophrenia. Objective: This study was designed to investigate the effects of phencyclidine (PCP) administration on performance in a rodent attentional set-shifting task and the neural correlates of PCP-induced deficits in task performance. Methods: Twenty-four hours following acute administration of 2.58 mg/kg PCP or vehicle, rats were tested on a perceptual attentional set shifting task (Birrell and Brown in J Neurosci 20:4320-4324, 2000). Following completion of the task, in situ hybridisation was employed to detect concurrent regional alterations in zif-268 and parvalbumin mRNA expression. Results: PCP administration selectively decreased the ability of rats to ...

N2 - N-methyl-D-aspartate (NMDA) receptor antagonists such as phencyclidine (PCP) can induce positive and negative symptoms of schizophrenia in humans and related effects in rodents. PCP treatment of developing rats induces apoptotic neurodegeneration and behavioral deficits later in life that mimic some symptoms of schizophrenia. The precise mechanism of PCP-induced neural degeneration is unknown. This study used selective antagonists, siRNA, and Western analysis to investigate the role of the Akt-glycogen synthase kinase-3β (GSK-3β) pathway in PCP-induced neuronal apoptosis in both neuronal culture and postnatal day 7 rats. PCP administration in vivo and in vitro reduced the phosphorylation of AktSer427 and GSK-3βSer9, decreasing Akt activity and increasing GSK-3β activity. The alteration of ...

N-methyl-d-aspartate (NMDA) receptor blockade in rodents induces behavioural and neurochemical changes reminiscent of schizophrenia symptoms and pathology. To examine how NMDA receptor blockade affects glutamatergic and GABAergic pathways when administered during early brain development, [3H]MK-801 and [3H]muscimol binding to NMDA and GABAA receptors was examined at four time-points following injections of phencyclidine (PCP) or saline on postnatal days (PN)7, 9 and 11. [3H]MK-801 binding was significantly increased in PCP-treated rats in the thalamus from PN18 to PN96, in the prefrontal and anterior cingulate cortices at PN32, and in the hippocampus at PN96. In a similar manner, [3H]muscimol binding was increased in PCP-treated rats in the thalamus and hippocampus from PN18 to PN96, and in the prefrontal and anterior cingulate cortices at PN32. Glutamatergic and GABAergic transmission is therefore chronically altered by this treatment, which has relevance to disease processes that may be involved in
Background: The main aim of the studies in this thesis is to provide insights into the neonatal phencyclidine (PCP) induced deficits in male and female rats as a neurodevelopmental animal model of schizophrenia. Methods: Both male and female rats were treated with neonatal PCP on postnatal days (PNDs) 7,9 and 11 or vehicle, followed by weaning on PND 21-22. The rats were then tested in behavioural paradigms such as novel object recognition, spatial memory and social interaction in their adolescent and adult stages and were also tested with acute treatment of typical and atypical antipsychotic agents. Results: Neonatal PCP treatment (10 & 20 mg/kg in males and 10 mg/kg in females; once a day for 3 days on PND 7,9 and 11) caused novel object recognition and spatial memory impairment in male and female rats both in the adolescent (PND35-56) and in the adult stages (PND,56) (chapter 2) and robust deficits in social interaction behaviours in the adolescent stage. The SI deficits were observed in ...

Some time later, Stinger met Jamal, Mark and all their friends at the place to where Jamal had followed Angel. Stinger gave each man a Stinger device and they all went down to the hidden shelters of homeless people. On the way down, he told them about his past as a super-villain. A homeless guy ran away from them and Stinger ordered Jamal to kill him. It wasnt Angel, but Stinger didnt care and ordered his allies to kill everyone they encountered. Stinger watched the homeless people die and screamed for Angel to come out and face him. Cloak and Dagger attacked Stingers boys and Stinger was able to knock out Cloak. Then he saw Angel attack Jamal, but Dagger used her light-daggers against Stinger and he had to retreat. Stinger fled from the heroes and the homeless people upstairs, to the subway, followed by Angel. They fought on the stairs and Angel fell over the railing when he avoided a shot with the Stinger device. Stinger wanted to decapitate him now, but Angel pulled out a knife and tossed ...

I didnt always believe in angels. My experience began when two friends gave me books about angels. They didnt even know each other, so the synchronicity seemed important. At that time my life was in turmoil and I needed help, but it never occurred to me that angels were real. I actually scoffed at the idea...but then I decided to pay attention and stay open to the possibility. I am so glad that I did. Angels are Gods messengers; they wing their way into our consciousness bringing divine thoughts that inspire, guide, and protect us. If you are not presently entertaining thoughts about angels, my wish is that this blog will encourage you stay open minded to receive their loving presence.. ...
The Angels, coming off an 80-82 record in 1966, started slowly. On May 31, they were 18-27 and 10 games out of first place. At that point, they began to jell, and after going 20-11 in June and 17-11 in July, they found themselves at 55-49. While this put them in fifth place, they only 4½ games out of first in what had become a five-team race between the Angels, Minnesota Twins, Detroit Tigers, Chicago White Sox, and the surprising Boston Red Sox.. On August 13, the Angels completed a 3-game sweep of the Red Sox. They were now only 1½ games out of first as they embarked on a crucial road trip that included stops in Minnesota and Boston. The Angels lost 3 games to the Twins, and 3 games in Boston (in one of which Bostons Tony Conigliaro was severely beaned and almost killed by the Angels Jack Hamilton). When they returned home, they Angels lost 3 out of 4 to the Tigers, and they entered September only 1 game over .500 and 8 games out of first.. They played well in September, going 17-11 to ...

Schizophrenia is a complex and debilitating psychiatric disorder. Dysfunction of the NMDA subtype of glutamate receptors is implicated in deficits found in schizophrenia, and some of these deficits may be reproduced in rodents using the NMDA receptor antagonist, phencyclidine (PCP). Nitric oxide synthase (NOS) is the synthesising enzyme of the gaseous neuromodulator, nitric oxide. The neuronal isoform of NOS (nNOS) is functionally associated with NMDA receptors. The role of NOS in schizophrenia is not fully understood. The primary aim of this thesis is to investigate NOS signalling in cultured neurones and in rodent PCP models of relevance to schizophrenia. Using diaminofluorescein microscopy of primary neuronal cultures, it is shown that non-selective inhibition of NOS using L-NAME, and selective inhibition of nNOS using L-NPA reversed glutamate-stimulated nitric oxide generation in hippocampal and cerebellar neurones, but inhibition of endothelial NOS using L-NIO did not. Novel c ompounds that ...
The Jewish view on angels is derived from the Hebrew word malach, which means both emissary and angel. Basically, angels are Gcds messengers. Each one is created for a specific task, and ceases to exist when that task is completed. Some angels have ongoing missions and thus exist for eons; other exist for a fleeting moment. The Rambam, based on a careful examination of angelic verses throughout the Torah, organized the types of angels into a ten-level hierarchy. They are, to use a cytology analogy, the messenger RNA in the great cytoplasm of the universe. ...
No matter your spiritual belief, sometimes we all feel in need of an angel under distressed moments. The safety and well-being of every partier is the number one concern for all promoters aside from having a good time. The scene, our community and this culture has gained notoriety in the public eye. And from the outside looking in, our community has been deemed to be a drug infested culture.. I would have to admit who doesnt like to liquor up when enjoying a night out with friends or family. Nevertheless, we are taught to do it responsibly and the same judgment must be adhered no matter the choice of party. As well, each and every one of us have the civic duty to keep our party peers safe and sound every step of the moment. But when complacency takes the best of us, there are still those roaming around watching over us. They may not be mystical Angels but they are still Angels: PLUR Angels.. PLUR Angels consists of volunteers who are committed to harm reduction and education for our community. ...
Angels were never so deliciously naughty! On the brink of Victoria Blooms twenty-fifth birthday she was being hunted by a demon, but her three wise spirit guides gave her the option to live. In order to do so she must summon an angel to act as her protector. What she didnt expect was getting an angel that was a despised being in the human world and was hell bent on staying in the heavens as much as possible.. Michael is above all things an archangel, staying in the heavens was what he most wanted to do. Then things changed as he is summoned to earth by a mouthy woman, who just happens to be his mate. Mortals die and he was not too thrilled to be bound to one, but he will do anything to keep this creature alive and well. And that includes killing a demon threatening her life.. Michael is one hell of an angel and he clearly loves Tory. Tory is a great heroine in that she doesnt back down from the angel even in the beginning when he clearly terrifies her. And The Three Stooges are hilarious. ...
I was on pilgrimage to the Holy Land, and was just about to celebrate Mass with a few friends in the little chapel overlooking the Sea of Galilee, when two middle-aged English women came hurrying up to join me. This is Edith, said one with a heavy Liverpool accent. She can see angels.. After Mass they took me out to lunch and told me a whole collection of delightful angel stories. Edith had seen a healing angel in the hospital. Shed seen the guardian angels of children. She dialogued with her guardian angel regularly and often looked out her kitchen window to see representatives of the heavenly host going about their business.. A rationalist skeptic would have written off Edith as a harmless eccentric at best and a poor, insane, religious kook at worst. Im happen to believe that what we consider reality (the day-to-day physical world) to be somewhat spongy. That is to say, it is far more flexible and porous than we would like to believe.

Imerman Angels was created on the belief that no one should have to fight cancer alone and without the necessary support. At 26 years old, Jonny Imerman was diagnosed with testicular cancer and began his fight against the disease. Throughout his experience, Jonny was lucky enough to have loving support from his family and friends but had never met anyone his age who was a cancer survivor. He wanted to talk to someone just like him, someone who truly understood, and was intimately familiar with his experience. In short, he was looking for someone who had already beaten the same type of cancer. This was the beginning of Jonnys vision and in 2003, it became a reality when he founded Imerman Angels.. Through their unique matching process, Imerman Angels partners anyone seeking cancer support with someone just like you - a Mentor Angel. A Mentor Angel is a cancer survivor or survivors caregiver who is the same age, same gender, and most importantly who has beaten the same type of cancer. A Mentor ...

Actually, he has received two so far, and they were from the UK, the first overseas cards he has ever received in his life! Thanks yall! He was so excited. And guess what else? He made it into the Chemo Angel program! He received a letter on Friday from a family. Then he received another letter from a woman on Saturday, lol. So he has two Angels, lol. What amazes me is how the Chemo Angel organization matched him up so well. I was worried that I specified too much on the form, and that they werent going to be able to find him anybody. But they did. I wont go into too much detail, for privacy reasons, but the first Angel had the same religion, liked cats, liked the same crafts as me, and had the same interests as John. The second Angel was a Christian also, was a cancer survior, and has had a bone marrow transplant! ...

Accumulating evidence suggests a role of oxidative stress in the pathophysiology of schizophrenia. The potent antioxidant sulforaphane (SFN) is an organosulfur compound derived from a glucosinolate precursor found in cruciferous vegetables such as broccoli, Brussels sprouts and cabbage. The protection afforded by SFN is thought to be mediated via activation of the NF-E2-related factor-2 (Nrf2) pathway and subsequent up-regulation of phase II detoxification enzymes and antioxidant proteins, through an enhancer sequence referred to as the electrophilic responsive element or antioxidant responsive element. Recently, we reported that SFN could attenuate behavioral abnormalities in mice after the NMDA receptor antagonist phencyclidine. Considering the potent antioxidant effects of SFN, we have a hypothesis that SFN would be a potential therapeutic drug for schizophrenia. The purpose of this study is to determine whether SFN-rich broccoli sprout extract have beneficial effects in patients with ...

Poster at the annual meeting of the European Brain and Behaviour Society (EBBS) 2013, Munich (Germany). Martin Engel, Xu-Feng Huang, Elisabeth Frank. Background: Neuregulin-1 is critical for neurodevelopment, but also found to alter acute brain signalling in adulthood. Alterations of the Neuregulin-1-ErbB4 signalling pathway are shown to be relevant for the schizophrenia pathology. ErbB4 receptors were found primarily located on GABAergic interneurons in schizophrenia-relevant brain areas, including the hippocampus. Using application of phencyclidine (PCP) both schizophrenia-like symptoms can be induced as well as GABAergic neurotransmission altered. Antagonism of PCP-induced effects was previously used as an indicator for the antipsychotic potential of a compound.. In the presented studies, we therefore explored the potential of Neuregulin-1 application to suppress PCP-induced hyperlocomotion as well as PCP-induced GABA release in the hippocampus.. Methods: For behavioural assessment, saline or ...

The concept of angel investment started on the 19th century in New York as a way to fund Broadway shows. After more than a century of low activity, for the last 30 years the angel investment industry has grown considerably. In the early 1980s, investors began to get together in order to co-invest and to brainstorm on new investment opportunities. Over time, this trend has been formalized, giving birth to angel networks, which are organizations that identify high-potential entrepreneurs and connects them with angel investors who are willing to tap into good opportunities.. The angel networks have been essential for the development of the industry and their main benefits are:. a) Democratization of the investment process, making possible for any startup to applied to the selection process of any angel network.. b) Significant increase of investment opportunities to be evaluated by angels investors.. c) Rigorous process where these opportunities are filtered according to investors criteria.. d) ...

Rationale: Aspects of schizophrenia, including deficits in sensorimotor gating, have been linked to glutamate dysfunction and/or oxidative stress in the prefrontal cortex. System xc −, a cystine-glutamate antiporter, is a poorly understood mechanism that contributes to both cellular antioxidant capacity and glutamate homeostasis. Objectives: Our goal was to determine whether increased system xc − activity within the prefrontal cortex would normalize a rodent measure of sensorimotor gating. Methods: In situ hybridization was used to map messenger RNA (mRNA) expression of xCT, the active subunit of system xc −, in the prefrontal cortex. Prepulse inhibition was used to measure sensorimotor gating; deficits in prepulse inhibition were produced using phencyclidine (0.3-3 mg/kg, sc). N-Acetylcysteine (10-100 μM) and the system xc − inhibitor (S)-4-carboxyphenylglycine (CPG, 0.5 μM) were used to increase and decrease system xc − activity, respectively.

ANGELS CAMP - You cant teach a frog to jump, laughed Dan Liechty, proprietor of White Pines Outdoors, a sporting goods store on Highway 4, north of Angels Camp. [...] Dan was wrong. According to Twain, according to Simon Wheeler, Jim Smiley had taught his frog how to jump, and Danl Webster did not lose due to a lack of training. The trees, like the giant sequoia of Calaveras Big Trees State Park, just north of Angels Camp, are still among the tallest (so are the tales) and the locals still get a kick out of eccentric sports like ostrich races and jumping frog jubilees. Cornish, Italian, Mexican, Russian and Chinese immigrants had settled around Angels trading post and taken up shovel and pick, swelling the population and creating the town. Today, with the help of the Calaveras Visitors Center, you can take a stroll through old Angels, on a walking tour that will point you toward historic places such as Crooked Nose Joes Saloon, the Waverly Stage Stop, up the chicken ladder on Hardscrabble
Is it ok to talk to the angels? Yes, it is. Lets take a look at why its perfectly ok to ask an angel for help.. The angels and archangels are messengers of the Truth of our Highest Creator and Source; God/Goddess. The angels are the extension of sacred, holy, and divine spirit. They are everywhere, and take any form according to the highest intelligence to reach us where we are at in our journey to peace. They are one of the most comforting and trusted messengers of the Love of God/Goddess above. And the message they bring reaches beyond all limitations.. The Holy Trinity. The angels are a part of the Divine, Holy Trinity. In this trinity, we have three different elements; the Creator, the Created, and the Process by Which Creation Occurs. Or, we have God, Goddess, and Divine Child. Thought, word, and deed. Will, spirit, and creation. Cause, process, and effect. In Christian, masculine dominated theology of the last few thousand years we have Father, Son, and Holy Spirit. But no matter how we ...

Ellen Muehlberger explores the diverse and inventive ideas Christians held about angels in late antiquity, focusing especially on the fourth and fifth centuries. At that time, Christians were experimenting with new modes of piety, adopting long-standing forms of public authority to Christian leadership and advancing novel ways of cultivating both body and mind to further the progress of individual Christians. She argues that in practicing these new modes of piety, Christians developed new ways of thinking about angels. The first half of the book is a detailed exploration of the two most popular discourses about angels that developed in late antiquity: in one, developed by Christians cultivating certain kinds of ascetic practices, angels were one type of being among many in a shifting universe, and their primary purpose was to guard and to guide Christians; in the other, voiced by urban Christian leaders contesting with one another, angels were morally stable characters described in the emerging canon of
A major goal of drug abuse research is to identify and understand drug-induced changes in brain function that are common to many or all drugs of abuse. As these may underlie drug dependence and addiction, the purpose of the present study was to examine if different drugs of abuse effect changes in gene expression that converge in common molecular pathways. Microarray analysis was employed to assay brain gene expression in postmortem anterior prefrontal cortex (aPFC) from 42 human cocaine, cannabis and/or phencyclidine abuse cases and 30 control cases, which were characterized by toxicology and drug abuse history. Common transcriptional changes were demonstrated for a majority of drug abuse cases (N = 34), representing a number of consistently changed functional classes: Calmodulin-related transcripts (CALM1, CALM2, CAMK2B) were decreased, while transcripts related to cholesterol biosynthesis and trafficking (FDFT1, APOL2, SCARB1), and Golgi/endoplasmic reticulum (ER) functions (SEMA3B, GCC1) were all
The noncompetitive NMDA receptor antagonist PCP induces a schizophrenia-like psychosis (including the positive, negative, and cognitive symptoms) in healthy humans and profoundly exacerbates preexisting symptoms in patients with schizophrenia. Thus, the administration of PCP to animals has become an attractive model of schizophrenia (Geyer and Ellenbroek, 2003). Like the atypical antipsychotic drug clozapine, mGlu2/3 receptor agonists have been shown to block PCP hyperactivity in rats (Moghaddam and Adams, 1998; Cartmell et al., 2000a; Monn et al., 2007). In this study, we assessed the ability of LY404039 to block PCP-induced hyperlocomotion in wild-type and mGlu receptor knockout mice. PCP administration increased motor ambulations and distance traveled and decreased the time spent at rest in wild-type and all mGlu receptor-deficient strains, effects that were reversed by the administration of LY404039 (10 mg/kg) in wild-type and mGlu3 receptor-deficient mice. Importantly, the ability of ...
Several important results were obtained from the present studies. First, in accordance with many previous reports, PCP was found repeatedly to disrupt PPI (Bakshi and Geyer, 1995; Bakshi et al., 1994; Mansbach and Geyer, 1989; Swerdlow et al., 1996; Wiley, 1994; Varty and Higgins, 1994; Johansson et al., 1994b). Second, the selective alpha-1 noradrenergic antagonist prazosin prevented the PCP-induced deficit in PPI. This effect was produced by multiple prazosin doses, was observed over multiple prepulse intensities and was replicated in a second separate experiment. Finally, selective antagonists for eitheralpha-2 (RX821002), muscarinic M1 (pirenzepine) or GABA-A (pitrazepin) receptors had no effect on the disruption of PPI produced by PCP. Taken together, these results indicate strongly that the impairment of sensorimotor gating induced by PCP involves the presumably indirect activation of alpha-1 adrenergic receptors, but probably not alpha-2, M1 or GABA-A receptors.. To the best of our ...

July 23: Harvey is now officially a free agent after clearing waivers, the Angels announced.. July 21: The Angels have requested unconditional release waivers on right-handed pitcher Matt Harvey, according to Rhett Bollinger of MLB.com. The move comes after Harvey was designated for assignment on Friday.. Thus continues a frustrating season for Harvey, who earned an $11MM contract from the Halos, representing an opportunity to re-establish himself as a viable rotation option after injuries derailed his career. Unfortunately, though, the contract has been a disaster for the playoff-hopeful Angels, who have by all measures received negative value from their one-year investment: Harveys ERA has ballooned to 7.09, the worst of his career. Other indicators paint a similar picture: with a 6.36 FIP and a .390 xwOBA, the Angels had little reason to continue trotting Harvey out to the mound every fifth day.. Harvey has seen his fastball velocity take yet another step back this season, continuing a trend ...
there have been many turbulences around the DARK ANGEL reunion and their show at KEEP IT TRUE lately. Right now it looks like there are two separate sections with on the one hand Don Doty and Eric Meyer and on the other hand Gene Hoglan and Jim Durkin, who fight each other with almost daily statements about who is the real DARK ANGEL. We watched this quietly for some days and hoped that all will be sorted out, but it seems there is no satisfying solution for everyone. KEEP IT TRUE stands for many years for honesty and credibility and we fear that these actions around the DARK ANGEL reunion can put damage on the good name of the festival. So we decided that NO version of Dark Angel will play on Keep It True 2014. We do not want to be in the middle of a fight where there is no end in sight. I hope you all understand our decision, we know some of you will be disappointed, but this is the only way for us. We will now look for a different Saturday headliner ...

BOSTON -- Jered Weaver could hear Garrett Richards scream from the dugout.. The Angels young starting pitcher was lying on the ground near first base at Fenway Park early in Wednesdays game, clutching his left knee and lying in agony for nearly 10 minutes before being lifted onto a stretcher. The Angels wont say anything definitive, but Richards stellar 2014 season looks finished, just as his team makes a final push for the American League West crown.. It doesnt look too good for him, Weaver said. Hes been our guy all year. Hes been that guy you count on to get deep in games and pull out a victory. To have something like that happen is obviously a crushing blow to any team. Our thoughts and prayers are with him, and hopefully it doesnt turn out as bad as everyone thinks it is.. As of midnight ET on Wednesday, the Angels at least know its a significant injury. Thats the term Angels manager Mike Scioscia repeatedly used when asked specific questions about Richards left knee after ...

Angels dont come to the reservation.. This is the first line of Natalie Diazs Abecedarian Requiring Further Examination of Anglikan Seraphym Subjugation of a Wild Indian Rezervation, and angels dont come to Natalie Diazs poems either. The angels might as well be cruising as high above them as jetliners. But even if they werent, theyd be about as welcome as the angel in Larry Leviss poem Anastasia & Sandman-the angel the starving man hated Because the angel could not be carved into meat.. According to Lorca, the angel dwells high above us, cold and distant. But for Diaz, the angel isnt just imperious-its imperial. Its a conqueror in wait. Her abecedarian ends with these lines: You better hope you never see angels on the rez. If you do, theyll be marching you off to / Zion or Oklahoma, or some other hell theyve mapped out for us.. Fortunately for us, the poems in Diazs commanding debut poetry collection, When My Brother Was an Aztec, dont rely on the angels. They embrace ...
Numerous studies have now demonstrated that a binding site for the psychotomimetic drug phencyclidine (PCP) exists within the receptor channel complex for the excitatory amino acid neurotransmitter glutamate, specifically the glutamate receptor selectively activated by N-methyl-D-aspartate (NMDA). Several lines of evidence support the hypothesis that all PCP receptors in rat brain are associated with the NMDA receptor complex. In the present study, we reexamine this hypothesis. We report that the PCP analog [3H]1-[1-(2-thienyl)cyclohexyl]piperidine [( 3H]TCP) labels two high affinity binding sites in membranes prepared from guinea pig brain site 1 (Kd = 14.1 nM, Bmax = 631 fmol/mg of protein) and site 2 (Kd = 46.5 nM, Bmax = 829 fmol/mg of protein). (+)-5-Methyl-10 11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine maleate bound to site 1 with high affinity (Kl = 3.2 nM) and to site 2 with low affinity (Kl = 5208 nM). The order of potency of drugs for inhibiting [3H]TCP binding to site 1 ...
Ketamine was discovered in 1962 and approved for use in the United States as a battlefield anaesthetic during the Vietnam war.. Calvin L. Stevens, a professor of chemistry at Wayne State University, made ketamine when he was conducting research on phencyclidine - an anaesthetic also known as angel dust, which worked well but caused hallucinations in people as they woke up. Ketamine was named CI-581 and was one-tenth as strong as phencyclidine. After research on animals, ketamine was tested on human prisoners in 1964 and 1965. Guenter Corssen, a professor of anaesthetics, conducted experiments on CI-581 using prisoners who had volunteered. He found it was a fast-acting anaesthetic that wore off quickly. Corssen reported that some of the men it was tested on had hallucinations. These included thinking they had died, their arms and legs had been cut off, or they had been to outer space. Some refused to continue in the research. Corssen was the first to call ketamine a dissociative anaesthetic, ...

There are a variety of clinically useful ergoline derivatives for the purpose of vasoconstriction, the treatment of migraines, and treatment of Parkinson's disease. Ergoline alkaloids found their place in pharmacology long before modern medicine as preparations of ergot were often used by midwives in the 12th century to stimulate childbirth.[10] Following Arthur Stoll's isolation of ergometrine, the therapeutic use of ergoline derivatives became well explored. The induction of uterine contractions via the preparation of ergot was attributed to ergonovine, an ergoline derivative found in ergot, which is a powerful oxytocic. From this, methergine, a synthetic derivative, was elucidated.[7] While used to facilitate child birth, ergoline derivatives can pass into breast milk and should not be used during breastfeeding.[11] They are uterine contractors that can increase the risk of miscarriage during pregnancy.[3] Another example of medically relevant ergoline alkaloids is ergotamine, an alkaloid ...
... (LA-SS-Az, LSZ) is an analog of LSD developed by the team led by David E. Nichols at Purdue University.[1][2] It was developed as a rigid analog of LSD with the diethylamide group constrained into an azetidine ring in order to map the binding site at the 5-HT2A receptor. There are three possible stereoisomers around the azetidine ring, with the (S,S)-(+) isomer being the most active, slightly more potent than LSD itself in drug discrimination tests using trained rats.[3] There have been several unconfirmed reports of lysergic acid 2,4-dimethylazetidide being synthesized in illicit laboratories and distributed on blotter paper or in liquid solution under names such as "diazedine" and "λ".[4][5] In 2013 LSZ also appeared on some designer drug and research chemical markets in the UK.[6][unreliable source?][7] LSZ later gained international popularity through a small cluster of mail-order novel psychedelic shops that appeared in 2012.[8] ...
... acts as a potent agonist for the 5HT2A receptor,[1][2] with a Ki of 0.061 nM at the human 5HT2A receptor, similar to the better-known compound 25I-NBOMe, making it some twelve times the potency of 2C-I itself. Although in vitro tests show this compound acts as an agonist, animal studies to confirm these findings have not been reported. While the N-benzyl derivatives of 2C-I had significantly increased binding to 5HT2A receptor fragments, compared to 2C-I, the N-benzyl derivatives of DOI were less active compared to DOI.[3] 25I-NBOH is notable as one of the most selective agonist ligands for the 5-HT2A receptor with an EC50 value of 0.074 nM with more than 400 times selectivity over the 5-HT2C receptor.[4] ...
... (5-bromo-N,N-dimethyltryptamine) is a psychedelic brominated indole alkaloid found in the sponges Smenospongia aurea and Smenospongia echina, as well as in Verongula rigida (0.00142% dry weight) alongside 5,6-Dibromo-DMT (0.35% dry weight) and seven other alkaloids.[1][2][3][4] It is the 5-bromo derivative of DMT, a psychedelic found in many plants and animals. 5-Bromo-DMT has a pEC50 value of 5.51 for the 5-HT2A receptor.[5] Animal studies on 5-Bromo-DMT showed that it produces effects suggestive of sedative and antidepressant activity and caused significant reduction of locomotor activity in the rodent FST model.[6] 5-Bromo-DMT was reported to be psychoactive at 20-50 mg via vaporization with mild psychedelic-like activity.[7] ...
... is a potent and long lasting anticholinergic deliriant drug, related to the chemical warfare agent 3-Quinuclidinyl benzilate (QNB). It was developed under contract to Edgewood Arsenal during the 1960s as part of the US military chemical weapons program, during research to improve upon the properties of earlier agents such as QNB. The main advantages of EA-3443 were not only increased potency over QNB, but also a significantly improved central to peripheral effects ratio. Anticholinergic drugs produce both incapacitating deliriant effects through action in the brain, and a variety of distinctive physical symptoms such as dry mouth, dilated pupils, blurred vision and hot flushed skin, all of which together comprise the "anticholinergic syndrome" which is generally easy for doctors to diagnose. EA-3443 however is mainly selective for the brain, and when administered in a narrow dose range of around 0.3mg can produce the central effects of confusion, hallucinations and amnesia, but without ...

In the United Kingdom, 2C-E is a Class A controlled substance. The UK has the strictest laws in the EU on designer drugs. The Misuse Of Drugs Act was amended in 2002 to include a "catch most" clause outlawing every drug, and possible future drug, from the LSD (ergoline) and MDMA (phenethylamine) chemical families (including 2C-E). The amendment is a near verbatim quote from the books of the American biochemist Alexander Shulgin, who obtained a PhD from the University of California, Berkeley. Dr. Shulgin, a former research chemist at the Dow Chemical Company, re-discovered the synthesis for MDMA in 1976 and published the syntheses for more than 200 phenethylamine compounds of his own invention, and 55 tryptamine compounds many of which were also his own invention. The Shulgins were motivated to release the synthesis information as a way to protect the public's access to information about psychedelic compounds, a goal Alexander Shulgin has noted many times. ...

In general, atropine counters the "rest and digest" activity of glands regulated by the parasympathetic nervous system. This occurs because atropine is a competitive, reversible antagonist of the muscarinic acetylcholine receptors (acetylcholine being the main neurotransmitter used by the parasympathetic nervous system). Atropine is a competitive antagonist of the muscarinic acetylcholine receptor types M1, M2, M3, M4 and M5.[28] It is classified as an anticholinergic drug (parasympatholytic). In cardiac uses, it works as a nonselective muscarinic acetylcholinergic antagonist, increasing firing of the sinoatrial node (SA) and conduction through the atrioventricular node (AV) of the heart, opposes the actions of the vagus nerve, blocks acetylcholine receptor sites, and decreases bronchial secretions. In the eye, atropine induces mydriasis by blocking contraction of the circular pupillary sphincter muscle, which is normally stimulated by acetylcholine release, thereby allowing the radial iris ...
... (INN) (brand names Lethidrone, Nalline), also known as N-allylnormorphine, is a mixed opioid agonist-antagonist with opioid antagonist and analgesic properties.[1] It was introduced in 1954[2] and was used as an antidote to reverse opioid overdose and in a challenge test to determine opioid dependence.[3] It acts at two opioid receptors - the μ-opioid receptor (MOR) where it has antagonistic effects, and at the κ-opioid receptor (KOR) (Ki = 1.6 nM; EC50 = 483 nM; Emax = 95%) where it exerts high-efficacy partial agonist/near-full agonist characteristics.[4] Nalorphine was the second opioid antagonist to be introduced, preceded by nalodeine (N-allylnorcodeine) in 1915 and followed by naloxone in 1960 and naltrexone in 1963.[2] Due to potent activation of the KOR, nalorphine produces side effects such as dysphoria, anxiety, confusion, and hallucinations, and for this reason, is no longer used medically.[1][2][5] Nalorphine has a number of analogues including niconalorphine (the ...
... (JB-318) is an anticholinergic drug related to the chemical warfare agent 3-Quinuclidinyl benzilate.. N-Ethyl-3-piperidyl benzilate is less potent and shorter acting than 3-quinuclidyl benzilate, but like 3-QNB its effects on the central nervous system predominate over peripheral effects. It produces deliriant and hallucinogenic effects similar to those of plants such as datura and may be used recreationally at low doses; however, unpleasant side effects such as dysphoria, nausea and vomiting, dizziness and extreme dry mouth tend to make abuse of drugs of this kind uncommon. Both the N-methyl and N-ethyl analogues of 3-piperidyl benzilate are, however, Schedule I controlled drugs.. Radiolabelled versions of this drug have been used in scientific research to map the distribution of muscarinic acetylcholine receptors in the brain, however this drug has slightly lower binding affinity than the N-methyl analogue and so is less potent and not so widely used for this ...

N,N-Dimethyllysergamide or N,N-dimethyl-D-lysergamide (DAM-57) is a derivative of ergine. There has been a single report of observing N,N-dimethyl-D-lysergamide in the illicit drug market.[1] This compound did induce autonomic disturbances at oral levels of some ten times the dosage required for LSD, presumably in the high hundreds of micrograms. There is some disagreement as to whether there were psychic changes observed.[2] ...
... is widely used in preparations as an enhancing agent for some analgesics and antitussives (acetaminophen, dihydrocodeine, codeine, hydrocodone). It is widely used in certain parts of the world as cough suppressant usually with codeine, and sometimes by itself or in addition to dextromethorphan as it, like diphenhydramine, possesses antitussive action of its own and is particularly useful in semi-productive coughs because of its moderate drying action. Phenyltoloxamine has analgesic and anti-spasmodic properties of its own[citation needed] and is used in combination with paracetamol, aspirin and other salicylates and other drugs in proprietary preparations available over the counter for backache, muscle strains and similar conditions. In this respect, it is similar to a closely related antihistamine, orphenadrine, and both drugs are very closely related to diphenhydramine and to doxylamine, the latter of which is the active ingredient in NyQuil and many other cough ...
Reports of recreational use of glaucine have recently been published, and effects include dissociative-type symptoms; feeling detached and 'in another world', as well as nausea, vomiting and dilated pupils. These reports mirror those about the effects of clinical use, which state dissociative-type symptoms as well as lethargy, fatigue, hallucinations.[8][9] Investigation of side effects in a clinical setting also reports that the hallucinatory effects manifest as bright and colorful visualizations. They also report that patients perceive their environments clearly yet feel detached from it; "the patient sees and understands everything and is oriented well enough, but cannot take a clear and adequate action".[8]. One particular report of recreational use gone awry described the form of distribution as tablets being marketed as a 1-benzylpiperazine (BZP)-free "herbal high" which the patient referred to as "head candy".[9]. ...
The full name of the chemical is 2,5-dimethoxy-4-bromoamphetamine. DOB has a stereocenter and R-(-)-DOB is the eutomer. This is an important finding as it is suggestive that it is targeting different receptors relative to most other phenethylamines (e.g. MDMA) where the R-isomer serves as the distomer. The toxicity of DOB is not fully known, although high doses may cause serious vasoconstriction of the extremities. DOB is one of the most potent compounds in PiHKAL; while the active dose is similar to that of DOI, another psychedelic amphetamine, DOB has been shown to have a higher efficacy in triggering downstream effects mediated by 5-HT2 receptors,[4] making it likely to be slightly more dangerous than DOI in overdose, due to greater vasoconstrictive action. Omission of the amphetamine related α-methyl leads to 2C-B, a compound that possesses a lower affinity for the 5-HT2A receptor and is a weaker receptor agonist which results in drastically reduced vasoconstriction.[citation needed] ...

... has been clinically tested in cancer patients for its pain relief and antiemetic benefits. Cancer patients that endure chemotherapy often develop intense nausea, and Levonantradol has been tested to reduce these emetic symptoms. It is often used instead of THC because it has a higher efficacy. Levonantradol also acts on pain pathways in the central nervous system, which enables the drug to alleviate pain. Studies have shown an absence of emetic side effects within the half-life of the Levonantradol administered. Other studies suggest that cannabinoid agonists can synergize opioid anti-nociception. Cannabinoid receptors are located in nociceptive pathways, and CBs can promote signal transduction in TRP channels. Although Levonantradol relieves nociceptive and postoperative pain, decreases nausea, and improves spasticity in addition to being more effective than placebos, it has yet to be approved as legal medicine. Researchers have concluded that Levonantradol is no more effective ...
... acts on M2 and M3[3] subtypes of muscarinic receptors whereas older antimuscarinic treatments for overactive bladder act more specifically on M3 receptors. Tolterodine, although it acts on all types of receptors, has fewer side effects than oxybutynin (M3 and M1 selective, but more so in the parotid than in the bladder) as tolterodine targets the bladder more than other areas of the body. This means that less drug needs to be given daily (due to efficient targeting of the bladder) and so there are fewer side effects.[citation needed] ...
