The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

A superfamily of PROTEIN-SERINE-THREONINE KINASES that are activated by diverse stimuli via protein kinase cascades. They are the final components of the cascades, activated by phosphorylation by MITOGEN-ACTIVATED PROTEIN KINASE KINASES, which in turn are activated by mitogen-activated protein kinase kinase kinases (MAP KINASE KINASE KINASES).
The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).
Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions.They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.

Solid-phase microextraction for cannabinoids analysis in hair and its possible application to other drugs. (1/1123)

This paper describes the application of solid-phase microextraction (SPME) to cannabis testing in hair. Fifty milligrams of hair was washed with petroleum ether, hydrolyzed with NaOH, neutralized, deuterated internal standard was added and directly submitted to SPME. The SPME was analyzed by GC-MS. The limit of detection was 0.1 ng/mg for cannabinol (CBN) and delta9-tetrahydrocannabinol (THC) and 0.2 ng/mg for cannabidiol (CBD). THC was detected in a range spanning from 0.1 to 0.7 ng/mg. CBD concentrations ranged from 0.7 to 14.1 ng/mg, and CBN concentrations ranged from 0.4 to 0.7 ng/mg. The effectiveness of different decontamination procedures was also studied on passively contaminated hair. The proposed method is also suitable for the analysis of methadone in hair; cocaine and cocaethylene can be detected in hair with SPME extraction after enzymatic hydrolysis.  (+info)

Toxicological findings in a fatal ingestion of methamphetamine. (2/1123)

This paper presents the case history of a fatality caused by the complications brought about by the presence of methamphetamine and ethanol. Drug concentrations are reported from samples obtained approximately 15 min after the subject was last observed to be chewing what was then believed to be gum, 3 h after the initial toxic symptoms were displayed, 6, 11, and 22 h later. The subjects conditions deteriorated over the course of this time, and he was declared dead 33 h after the initial display of toxic symptoms. The toxicological findings and concentration levels of the reported biological specimens concurred with the expected findings in a case of methamphetamine toxicity.  (+info)

The central cannabinoid receptor (CB1) mediates inhibition of nitric oxide production by rat microglial cells. (3/1123)

Upon activation, brain microglial cells release proinflammatory mediators, such as nitric oxide (NO), which may play an important role in the central nervous system antibacterial, antiviral, and antitumor activities. However, excessive release of NO has been postulated to elicit immune-mediated neurodegenerative inflammatory processes and to cause brain injury. In the present study, the effect of cannabinoids on the release of NO from endotoxin/cytokine-activated rat cortical microglial cells was evaluated. A drug dose-dependent (0.1 microM-8 microM) inhibition of NO release from rat microglial cells was exerted by the cannabinoid receptor high-affinity binding enantiomer (-)-CP55940. In contrast, a minimal inhibitory effect was exerted by the lower affinity binding paired enantiomer (+)-CP56667. Pretreatment of microglial cells with the Galphai/Galphao protein inactivator pertussis toxin, cyclic AMP reconstitution with the cell-permeable analog dibutyryl-cAMP, or treatment of cells with the Galphas activator cholera toxin, resulted in reversal of the (-)-CP55940-mediated inhibition of NO release. A similar reversal in (-)-CP55940-mediated inhibition of NO release was effected when microglial cells were pretreated with the central cannabinoid receptor (CB1) selective antagonist SR141716A. Mutagenic reverse transcription-polymerase chain reaction, Western immunoblot assay using a CB1 receptor amine terminal domain-specific antibody, and cellular colocalization of CB1 and the microglial marker Griffonia simplicifolia isolectin B4 confirmed the expression of the CB1 receptor in rat microglial cells. Collectively, these results indicate a functional linkage between the CB1 receptor and cannabinoid-mediated inhibition of NO production by rat microglial cells.  (+info)

Cannabinoid suppression of noxious heat-evoked activity in wide dynamic range neurons in the lumbar dorsal horn of the rat. (4/1123)

The effects of cannabinoid agonists on noxious heat-evoked firing of 62 spinal wide dynamic range (WDR) neurons were examined in urethan-anesthetized rats (1 cell/animal). Noxious thermal stimulation was applied with a Peltier device to the receptive fields in the ipsilateral hindpaw of isolated WDR neurons. To assess the site of action, cannabinoids were administered systemically in intact and spinally transected rats and intraventricularly. Both the aminoalkylindole cannabinoid WIN55,212-2 (125 microg/kg iv) and the bicyclic cannabinoid CP55,940 (125 microg/kg iv) suppressed noxious heat-evoked activity. Responses evoked by mild pressure in nonnociceptive neurons were not altered by CP55,940 (125 microg/kg iv), consistent with previous observations with another cannabinoid agonist, WIN55,212-2. The cannabinoid induced-suppression of noxious heat-evoked activity was blocked by pretreatment with SR141716A (1 mg/kg iv), a competitive antagonist for central cannabinoid CB1 receptors. By contrast, intravenous administration of either vehicle or the receptor-inactive enantiomer WIN55,212-3 (125 microg/kg) failed to alter noxious heat-evoked activity. The suppression of noxious heat-evoked activity induced by WIN55,212-2 in the lumbar dorsal horn of intact animals was markedly attenuated in spinal rats. Moreover, intraventricular administration of WIN55,212-2 suppressed noxious heat-evoked activity in spinal WDR neurons. By contrast, both vehicle and enantiomer were inactive. These findings suggest that cannabinoids selectively modulate the activity of nociceptive neurons in the spinal dorsal horn by actions at CB1 receptors. This modulation represents a suppression of pain neurotransmission because the inhibitory effects are selective for pain-sensitive neurons and are observed with different modalities of noxious stimulation. The data also provide converging lines of evidence for a role for descending antinociceptive mechanisms in cannabinoid modulation of spinal nociceptive processing.  (+info)

Effect of the cannabinoid receptor agonist WIN55212-2 on sympathetic cardiovascular regulation. (5/1123)

1. The aim of the present study was to analyse the cardiovascular actions of the synthetic CB1/CB2 cannabinoid receptor agonist WIN55212-2, and specifically to determine its sites of action on sympathetic cardiovascular regulation. 2. Pithed rabbits in which the sympathetic outflow was continuously stimulated electrically or which received a pressor infusion of noradrenaline were used to study peripheral prejunctional and direct vascular effects, respectively. For studying effects on brain stem cardiovascular regulatory centres, drugs were administered into the cisterna cerebellomedullaris in conscious rabbits. Overall cardiovascular effects of the cannabinoid were studied in conscious rabbits with intravenous drug administration. 3. In pithed rabbits in which the sympathetic outflow was continuously electrically stimulated, intravenous injection of WIN55212-2 (5, 50 and 500 microg kg(-1)) markedly reduced blood pressure, the spillover of noradrenaline into plasma and the plasma noradrenaline concentration, and these effects were antagonized by the CB1 cannabinoid receptor-selective antagonist SR141716A. The hypotensive and the sympathoinhibitory effect of WIN55212-2 was shared by CP55940, another mixed CB1/CB2 cannabinoid receptor agonist, but not by WIN55212-3, the enantiomer of WIN55212-2, which lacks affinity for cannabinoid binding sites. WIN55212-2 had no effect on vascular tone established by infusion of noradrenaline in pithed rabbits. 4. Intracisternal application of WIN55212-2 (0.1, 1 and 10 microg kg(-1)) in conscious rabbits increased blood pressure and the plasma noradrenaline concentration and elicited bradycardia; this latter effect was antagonized by atropine. 5. In conscious animals, intravenous injection of WIN55212-2 (5 and 50 microg kg(-1)) caused bradycardia, slight hypotension, no change in the plasma noradrenaline concentration, and an increase in renal sympathetic nerve firing. The highest dose of WIN55212-2 (500 microg kg(-1)) elicited hypotension and tachycardia, and sympathetic nerve activity and the plasma noradrenaline concentration declined. 6. The results obtained in pithed rabbits indicate that activation of CB1 cannabinoid receptors leads to marked peripheral prejunctional inhibition of noradrenaline release from postganglionic sympathetic axons. Intracisternal application of WIN55212-2 uncovered two effects on brain stem cardiovascular centres: sympathoexcitation and activation of cardiac vagal fibres. The highest dose of systemically administered WIN55212-2 produced central sympathoinhibition; the primary site of this action is not known.  (+info)

Stage-specific excitation of cannabinoid receptor exhibits differential effects on mouse embryonic development. (6/1123)

Anandamide (N-arachidonoylethanolamine), an arachidonic acid derivative, is an endogenous ligand for both the brain-type (CB1-R) and spleen-type (CB2-R) cannabinoid receptors. We have previously demonstrated that preimplantation mouse embryos express mRNA for these receptors and that the periimplantation uterus contains the highest level of anandamide yet discovered in a mammalian tissue. We further demonstrated that 2-cell mouse embryos exposed to low levels of anandamide (7 nM) or other known cannabinoid agonists in culture exhibit markedly compromised embryonic development to blastocysts and that this effect is mediated by CB1-R. In contrast, the present study demonstrates that blastocysts exposed in culture to the same low levels of cannabinoid agonists exhibited accelerated trophoblast differentiation with respect to fibronectin-binding activity and trophoblast outgrowth. Again, these effects resulted from activation of embryonic CB1-R. There was a differential concentration-dependent effect of cannabinoids on the trophoblast, with an observed inhibition of differentiation at higher doses. These results provide evidence for the first time that cannabinoid effects are differentially executed depending on the embryonic stage and cannabinoid levels in the environment. Since uterine anandamide levels are lowest at the sites of implantation and highest at the interimplantation sites, the new findings imply that site-specific levels of anandamide and/or other endogenous ligands in the uterus may regulate implantation spatially by promoting trophoblast differentiation at the sites of blastocyst implantation.  (+info)

A role for N-arachidonylethanolamine (anandamide) as the mediator of sensory nerve-dependent Ca2+-induced relaxation. (7/1123)

We tested the hypothesis that an endogenous cannabinoid (CB) receptor agonist, such as N-arachidonylethanolamine (anandamide), is the transmitter that mediates perivascular sensory nerve-dependent Ca2+-induced relaxation. Rat mesenteric branch arteries were studied using wire myography; relaxation was determined after inducing contraction with norepinephrine. Cumulative addition of Ca2+ caused dose-dependent relaxation (ED50 = 2.2 +/- 0.09 mM). The relaxation was inhibited by 10 mM TEA and 100 nM iberiotoxin, a blocker of large conductance Ca2+-activated K+ channels, but not by 5 microM glibenclamide, 1 mM 4-aminopyridine, or 30 nM apamin. Ca2+-induced relaxation was also blocked by the selective CB receptor antagonist SR141716A and was enhanced by pretreatment with 4-(2-aminoethyl)benzenesulfonyl fluoride hydrochloride (pefabloc; 30 microM), an inhibitor of anandamide metabolism. Anandamide also caused dose-dependent relaxation (ED50 =.72 +/- 0.3 microM). The relaxation was not inhibited by endothelial denudation, 10 microM indomethacin, or 1 microM miconazole, but was blocked by 3 microM SR141716A, 10 mM TEA, precontraction with 100 mM K+, and 100 nM iberiotoxin, and was enhanced by treatment with 30 microM pefabloc. Mesenteric branch arteries were 200-fold more sensitive to the relaxing action of anandamide than arachidonic acid (ED50 = 160 +/- 7 microM). These data show that: 1) Ca2+ and anandamide cause hyperpolarization-mediated relaxation of mesenteric branch arteries, which is dependent on an iberiotoxin-sensitive Ca2+-activated K+ channel, 2) relaxation induced by both Ca2+ and anandamide is inhibited by CB receptor blockade, and 3) relaxation induced by anandamide is not dependent on its breakdown to arachidonic acid and subsequent metabolism. These findings support the hypothesis that anandamide, or a similar cannabinoid receptor agonist, mediates nerve-dependent Ca2+-induced relaxation in the rat.  (+info)

Agonist-inverse agonist characterization at CB1 and CB2 cannabinoid receptors of L759633, L759656, and AM630. (8/1123)

We have tested our prediction that AM630 is a CB2 cannabinoid receptor ligand and also investigated whether L759633 and L759656, are CB2 receptor agonists. Binding assays with membranes from CHO cells stably transfected with human CB1 or CB2 receptors using [3H]-CP55940, confirmed the CB2-selectivity of L759633 and L759656 (CB2/CB1 affinity ratios = 163 and 414 respectively) and showed AM630 to have a Ki at CB2 receptors of 31.2 nM and a CB2/CB1 affinity ratio of 165. In CB2-transfected cells, L759633 and L759656 were potent inhibitors of forskolin-stimulated cyclic AMP production, with EC50 values of 8.1 and 3.1 nM respectively and CB1/CB2 EC50 ratios of > 1000 and > 3000 respectively. AM630 inhibited [35S]-GTPgammaS binding to CB2 receptor membranes (EC50 = 76.6 nM), enhanced forskolin-stimulated cyclic AMP production in CB2-transfected cells (5.2 fold by 1 microM), and antagonized the inhibition of forskolin-stimulated cyclic AMP production in this cell line induced by CP55940. In CB1-transfected cells, forskolin-stimulated cyclic AMP production was significantly inhibited by AM630 (22.6% at 1 microM and 45.9% at 10 microM) and by L759633 at 10 microM (48%) but not 1 microM. L759656 (10 microM) was not inhibitory. AM630 also produced a slight decrease in the mean inhibitory effect of CP55940 on cyclic AMP production which was not statistically significant. We conclude that AM630 is a CB2-selective ligand that behaves as an inverse agonist at CB2 receptors and as a weak partial agonist at CB1 receptors. L759633 and L759656 are both potent CB2-selective agonists.  (+info)

Prolonged exposure of rats to the synthetic cannabinoid receptor ligand, CP-55,940 (0.4 mg/kg, i.p. for 11 days), induced tolerance to analgesia, to the reduction in spontaneous locomotor activity and the incidence of splayed hind limbs. One hour after the last injection on day 11, the rats were killed and in situ hybridization was used to investigate the effect of treatment on G-protein alpha-subunit expression throughout the brain. Chronic cannabinoid exposure markedly reduced G alpha(s), G alpha(i) and G alpha(o) mRNA levels. The message for the alpha(s)-subunit was decreased in all the brain areas containing the basal autoradiographic signal; the decrease ranging from 25% in the thalamus to 45% in the mesencephalon. Also the basal G alpha(i) expression was reduced in tolerant rats showing the greatest decrease in the forebrain (63%) in the cerebellum (58%) and in the mesencephalon (38%). The reduction in G alpha(o) expression (25%) was more localized, being present only in the rostral portion of the
In an increasingly ageing population, the incidence of neurodegenerative disorders such as Alzheimers disease, Parkinsons disease and Huntingtons disease are rising. While the aetiologies of these disorders are different, a number of common mechanisms that underlie their neurodegenerative components have been elucidated; namely neuroinflammation, excitotoxicity, mitochondrial dysfunction and reduced trophic support. Current therapies focus on treatment of the symptoms and attempt to delay the progression of these diseases but there is currently no cure. Modulation of the endogenous cannabinoid system is emerging as a potentially viable option in the treatment of neurodegeneration. Endocannabinoid signalling has been found to be altered in many neurodegenerative disorders. To this end, pharmacological manipulation of the endogenous cannabinoid system, as well as application of phytocannabinoids and synthetic cannabinoids have been investigated. Signalling from the CB1 and CB2 receptors are ...
Synthetic cannabinoids - drugs that mimic the psychoactive effect of cannabis - have been linked to injuries and deaths. When one is banned, another rises to take its place.
All these effects are thought to be caused by cannabinoids locking onto the CB1 and CB2 cannabinoid receptors. It also looks like cannabinoids can exert effects on cancer cells that dont involve cannabinoid receptors, although it isnt yet clear exactly whats going on there.. So far, the best results in the lab or animal models have come from using a combination of highly purified THC and cannabidiol (CBD), a cannabinoid found in cannabis plants that counteracts the psychoactive effects of THC. But researchers have also found positive results using synthetic cannabinoids, such as a molecule called JWH-133.. Its not all good news though, as theres also evidence that cannabinoids may also have undesirable effects on cancer.. For example, some researchers have found that although high doses of THC can kill cancer cells, they also harm crucial blood vessel cells, although this may help their anti-cancer effect by preventing blood vessels growing into a tumour. And under some circumstances, ...

First emergent in Europe in 2004, an herbal incense product known as Spice or K2 was quickly utilized all over the world as a synthetic form of marijuana. Although sold legally in many areas as a natural incense that is not for human consumption, K2 is a plant-based material with traces of astoundingly potent synthetic cannabinoids, a fact that many users and retailers alike do not fail to recognize. Synthetic cannabinoids (SCBs) are chemically derived forms of the naturally-occurring psychotropic cannabinoid, tetrahydrocannabinol (THC), found in marijuana [1][2]. Cannabinoids bind and activate cannabinoid receptors, CB1 and CB2, which are found throughout the body [1]. CB1 is primarily found in the cerebellum as well as the hippocampus, hypothalamus, cerebral cortex, striatum and brainstem; all vital areas of the central nervous system [1]. Although SCBs are chemically similar to THCs, which exhibit relatively mild side effects when used recreationally, the use of K2 has been linked to many ...

To our knowledge, this is the first study to explore the association between ever use of synthetic cannabinoids and health risk behaviors in domains such as injury/violence, mental health, and sexual health among a nationally representative sample of US high school students. Furthermore, this study contributes new evidence on how behavioral correlates differ by type of marijuana use. Overall, we observed that ever use of synthetic cannabinoids was associated with the majority of health risk behaviors included in our study and that those associations tended to be more pronounced for ever use of synthetic cannabinoids than for ever use of marijuana only, particularly for substance use behaviors and sexual risk behaviors.. Given that synthetic cannabinoids are a relatively recent issue in the United States, high school students use of the drug was not monitored in national surveillance systems until the 2011 MTF study cycle1 and the 2015 YRBS cycle.21 As a result, much of the available literature ...

TY - JOUR. T1 - Sickle Cell Crisis Complicated by Synthetic Cannabinoid Abuse. T2 - A Case Report. AU - Zheng, Crystal Y.. AU - Minniti, Caterina P.. AU - Chaitowitz, Mark H.. PY - 2016/3/4. Y1 - 2016/3/4. N2 - We describe a case of delirium occurring in a hospitalized sickle cell patient. Following admission for a typical pain crisis, the patient continued to report unrelieved pain with marked agitation for several days, despite escalating doses of opioid analgesia, and ultimately required intubation following development of acute chest syndrome (ACS). After some delay, it was discovered that he had been using a synthetic cannabinoid (K2) which may have precipitated his pain crisis and, with hindsight, explained his prolonged period of delirium. Delayed recognition was due to multiple factors, notably the absence of an index of suspicion for this novel drug, the presence of alternate explanations for the patients altered mental status, and the fact that reliable laboratory screening for ...

Studies have been conducted to highlight the anti-inflammatory and immunosuppressive properties of cannabinoids and also their potentials for cartilage repair and regeneration. Various wound healing techniques can be used to investigate the mechanisms of chondrocyte repair in monolayers or three dimensional tissue constructs. The effect of different concentrations of the synthetic cannabinoids WIN55, 212-2 (WIN-2), URB602 and HU-308 with and without their antagonists on the wound healing of chondrocyte monolayers was investigated using a simple scratch assay model. The three cannabinoids were found to increase wound healing of chondrocyte monolayers, but at different rates. WIN55, 212-2 at a concentration of 1μM had the highest effect of increasing both migration and proliferation of chondrocytes cultured in a chondrogenic media, which increased the rate of wound closure. It was also found that treating the cells with 2μM of any of the cannabinoids lead to a decrease in cell proliferation and ...
Tylenol/Acetaminophen is a synthetic cannabinoid Its in reality a cannabinoid prodrug. After a few metabolic steps, it reaches the talent and combines with arachidonic acid to shape AM404. Now AM404 is surely a hell of a cannabinoid, and is idea to be responsible for most, if not all of the…

Y1 - 2012/2. N2 - AIM: Plant cannabinoids, like Δ(9)-tetrahydrocannabinol (THC) and cannabidiol (CBD), activate/desensitize thermosensitive transient receptor potential (TRP) channels of vanilloid type-1 or -2 (TRPV1 or TRPV2). We investigated whether cannabinoids also activate/desensitize two other thermo-TRPs, the TRP channels of vanilloid type-3 or -4 (TRPV3 or TRPV4), and if the TRPV-inactive cannabichromene (CBC) modifies the expression of TRPV1-4 channels in the gastrointestinal tract.METHODS: TRP activity was assessed by evaluating elevation of [Ca(2+)](i) in rat recombinant TRPV3- and TRPV4-expressing ...

A new study published by the National Institute of Health has found that cannabinoids can be an effective treatment for acute lung injury.
CB 2 agonists demonstrate remarkable anti inflammatory properties but , your , idea of receptor attraction has some merit, at least with respect to the , CB , 1 receptor. I recall an old study wherein they found that cannabis , tolerance , was proportional to the level of receptor retraction from the cell , surface. I wonder if, as with mu opioid tolerance, this effect is mediated by a PKC. Would inhibiting that PKC result in elevation of cannabinoid receptor levels? Also, B-cell proliferation appears to be partly under the regulation of a CB, although the research hasnt clarified it well yet. Ive always wondered if the way loss of gut bacteria knocks out the mu opioid and cannabinoid receptors of the gut wasnt also kicking antibody/B-cell production into needless overdrive (hence the use of B-cell depletion agents in autoimmune condition). , This does raise some worrying questions with respect to the chronic , ingestion of the same but the studies tend to find little ill effects. , ...
Learn about the differences between synthetic cannabinoids vs real cannabis, and find out why synthetic is so dangerous and can even cause death.
Thanks Kofi, interesting stuff. CB 2 agonists demonstrate remarkable anti inflammatory properties but your idea of receptor attraction has some merit, at least with respect to the CB 1 receptor. I recall an old study wherein they found that cannabis tolerance was proportional to the level of receptor retraction from the cell surface. This does raise some worrying questions with respect to the chronic ingestion of the same but the studies tend to find little ill effects. Cannabidol, the non-psychoactive form, strikes me as an excellent target for therapeutic potential. A recent news release about some research indicated that topical application of THC, which does ligand to the CB 2, had strong anti-allergic effects, sufficient to warrant clinical trials. This is entirely concordant with other studies showing that CB 2 activation down regulates excessive inflamation being driven by innate immune responses. Thanks, John. Kofi ,kofi from anon.un, wrote in message news:kofi-59A74F.20025514062007 ...
The use of synthetic cannabinoid receptor (CBR) ligands for therapeutic use has provided problems regarding the natural endogenous regulatory tone of the eCBs, which in turn has resulted in unwanted side effects. Part of the reason of this is due to synthetic agonists producing the well documented psychotropic effects at CB t receptors. Alternative targets for the manipulation of the eCB system for therapeutic benefits have been explored. One remains to be the use of FAAH inhibitors, which in turn potentially increase levels of eCBs in the system, hence potentiating their effects at the CBRs, or at other receptor sites. Therefore we have developed two HTS assays for the identification of potential inhibitors of FAAH and MAGL. They prove to be robust, cheap and facile and provide a clear indication of inhibitable levels of FAAH and MAGL activity. The FAAH assay can be further used to establish concentration-response curves of initial `hit compounds. Yet, the HTS MAGL assay requires further ...
The term Terpene is not new in the market. Still, very few people are aware of its existence. Terpenes are organic compounds found in cannabis plants that give them flavor and fragrance. Now its easier to understand why every cannabis plant has a unique flavor and aroma. Youll be surprised to know that over 100 different Terpenes strains have already been identified in the cannabis plant and have their unique composition. Some strains produce a citrusy aroma, some smell like lavender, while others can smell more earthy and pungent.. Cannabis has a unique smell. Most people find it calming and enjoyable. This is all because of the Terpene strains that are packed in the sticky glands of the cannabis plant. They are the reason that cannabis plants get such a distinctive smell. This substance has two primary roles in every plants life: to protect the flowers from predators and to produce resin. The terpenes are a good fit for medical and beauty products. When we study the term organic terpenes, ...
Comparing dopaminergic dynamics in the dorsolateral striatum between adolescent and adult rats- Effect of an acute dose of WIN55212-2. Brief summary: A recent study has exposed an age-dependent mechanism within the dopaminergic system that relies on cannabinoid receptor 1 (CB1). Adult and adolescent dopamine levels were examined in the presence of a CB1 agonist and increased levels of extracellular dopamine were found in adolescents. This study reveals the different effects cannabis-based medicine has depended on the age of the patient and warrants future research to ensure cannabis has the desired therapeutic effect on patients. Dr Caplan Discussion Points:. This adds a helpful layer of insight to the way an animal model of dopamine changes over time, as well as its interaction with exogenous cannabinoids. This sheds light on the natural evolution of the dopamine control system (irrespective of how it interacts with endocannabinoids), and it also points to how cannabinoids may be ...
CBD For Back Pain For thousands of years, the cannabis plant has been used to alleviate different types of pain that affect the body.

L-759,656 is an analgesic drug that is a cannabinoid agonist. It is a highly selective agonist for the CB2 receptor, with selectivity of 414x for CB2 over CB1,[1] although it is still not as selective as newer agents such as HU-308. It produces some similar effects to other cannabinoid agonists such as analgesia, but with little or no sedative or psychoactive effects due to its weak CB1 activity, and a relatively strong antiinflammatory effect due to its strong activity at CB2.[2][3] ...

Researchers from the University of Twentes MESA+ and MIRA research institutes have succeeded in visualizing THC, the active ingredient of cannabis, in intact plant structures. The substance is mainly found in trichomes (fine outgrowths) and in the small leaves around the flowers of the cannabis plant. Little or no THC is present in the stems and flowers. While these findings are not new, the study carried out by these researchers has shown their method (hyperspectral CARS Microscopy) to be a powerful tool for investigating the medicinal properties of plants. An article describing this research was published today in a scientific journal, the Journal of Biomedical Optics.. Plants have developed a range of mechanisms for synthesizing substances that happen to have medicinal properties. These mechanisms are often better or more efficient than those available to us in the lab. If we can find out how and where plants produce the requisite materials, we may be able to imitate nature. Using ...

No analytical confirmation of synthetic cannabinoids have been presented to the media or published elsewhere for these cases, but I would expect that they are diligently working on this behind the scenes. Of course this is just speculation, but I wouldnt be surprised that this is the work of one of the newer generation synthetic cannabinoids such as AB-PINACA, AB-CHMINACA, or maybe even a PB-22 derivative such as FDU-PB-22. I only know of a lab or two that routinely tests for some of these newer compounds in blood, let alone urine specimens. Also, considering the cat-and-mouse games that are played with these drugs, there may be (and probably is) a new cannabinoid on the scene which we arent even aware. We must always remember that we know very little (if anything) about the chemistry, pharmacology, and toxicology of these compounds used in herbal incese/potpourri blends. ...
An interesting feature of these newer synthetic cannabinoids is the ester or amide linkages. These linkages were not included in the earlier waves of cannabinoid compounds (i.e. JWH-018 → AM-2201 → UR-144...) as they contained the simple ketone linkage. The ester linkage is seen in the quinolinyl carboxylate derivative compounds such as PB-22, 5F-PB-22 and BB-22, while the amide linkage is seen the many of these newer substances such as the various ADBs, PINACAs, and FUBINACAs. Regarding these amide-containing cannabinoids (structures referenced in the figure above in red-color and in a previous blog post here), the amide linkage can be very susceptible to hydrolysis reactions. In the case of the two compounds related to the Colorado cases, possible in vivo amide hydrolysis would lead to formation of a carboxylic acid and an amine. Could this amine be active in the body? Possibly. ...

The four main findings of this study are as follows: (1) the cannabinoid agonist WIN 55,212-2 induced conditioned place aversion; (2) WIN 55,212-2 suppressed spontaneous locomotor activity given at doses of 2.0 and 10.0 mg/kg; (3) animals experienced a significant weight loss during treatment with the doses of 2.0 and 10.0 mg/kg of the cannabinoid agonist and during the following 14 d; and (4) rats with an extended background of EtOH self-administration and treated with WIN 55,212-2 during alcohol deprivation showed a long-lasting increase in their responding for alcohol. In contrast, when the animals passed periods of abstinence only from alcohol, they only showed a temporary increase in their EtOH consumption. This last finding is in agreement with most studies (Heyser et al., 1998, 2003; Rodd-Henricks et al., 2000; Samson et al., 2001; Serra et al., 2002; Cowen et al., 2003; Vengeliene et al., 2003)..

By James E. Brumley] In mid-September, Vitality Biopharma Inc (OTCMKTS:VBIO) announced it was going to take aim at the development of an alternative to opioids as a means of treating pain. At the time, there was little doubt that the companys cannabinoid science was capable of doing so. What wasnt clear to VBIO shareholders was exactly how that might happen…. meaning what sort of drug might Vitality Biopharma come up with. We got the first of what will likely be several answers to the question today. Per todays press release, Vitality Biopharma intends to come up with a treatment for narcotic bowel syndrome, which is a severe form of (ironically enough) opiate-induced abdominal pain.. As a refresher, Vitality Biopharma was the name we introduced to you back on August 8th, pointing out it had developed a whole new way of making cannabinoid-based medicines. Their versions offer all the upsides of cannabinoids, but without the psychotropic (getting high) effects, and without some of the ...

Nick, this could also be seen as payback.. The DEA has been terrorizing pain doctors for over a decade now. Im quite sure that it has crossed the awareness of the AMA that by doing this, they have set in motion the machinery that could, in essence, destroy the DEA. For as everyone with three brain cells to click together knows, cannabis prohibition is the lynch-pin of drug prohibition en toto, and if that lynch-pin is removed, the entire train will come to a screeching halt.. This can only go in one direction, now. …facilitating the conduct of clinical research and development of cannabinoid-based medicines,…. Despite its disclaimer, the AMA, by doing this, has thrown the gauntlet. The AMAs demand for this kind of research is a sword aimed directly at the ONDCPs and the DEAs necks, for its as clear a challenge as can be made to the political power of the DEA by demanding that science instead of politics play a role in determining policy, which is exactly what Prez Obama said he ...
