Alkaloids
Organic nitrogenous bases. Many alkaloids of medical importance occur in the animal and vegetable kingdoms, and some have been synthesized. (Grant & Hackh's Chemical Dictionary, 5th ed)
Oils, Volatile
Oils which evaporate readily. The volatile oils occur in aromatic plants, to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleoptene (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant, as its perfume or scent, and not to its indispensability.

Bronchodilator and anti-inflammatory activities of glaucine: In vitro studies in human airway smooth muscle and polymorphonuclear leukocytes. (1/80)
1. Selective phosphodiesterase 4 (PDE4) inhibitors are of potential interest in the treatment of asthma. We examined the effects of the alkaloid S-(+)-glaucine, a PDE4 inhibitor, on human isolated bronchus and granulocyte function. 2. Glaucine selectively inhibited PDE4 from human bronchus and polymorphonuclear leukocytes (PMN) in a non-competitive manner (Ki=3.4 microM). Glaucine displaced [3H]-rolipram from its high-affinity binding sites in rat brain cortex membranes (IC50 approximately 100 microM). 3. Glaucine inhibited the spontaneous and histamine-induced tone in human isolated bronchus (pD2 approximately 4.5). Glaucine (10 microM) did not potentiate the isoprenaline-induced relaxation but augmented cyclic AMP accumulation by isoprenaline. The glaucine-induced relaxation was resistant to H-89, a protein kinase A inhibitor. Glaucine depressed the contractile responses to Ca2+ (pD'2 approximately 3.62) and reduced the sustained rise of [Ca2+]i produced by histamine in cultured human airway smooth muscle cells (-log IC50 approximately 4.3). 4. Glaucine augmented cyclic AMP levels in human polymorphonuclear leukocytes challenged with N-formyl-Met-Leu-Phe (FMLP) or isoprenaline, and inhibited FMLP-induced superoxide generation, elastase release, leukotriene B4 production, [Ca2+]i signal and platelet aggregation as well as opsonized zymosan-, phorbol myristate acetate-, and A23187-induced superoxide release. The inhibitory effect of glaucine on superoxide generation by FMLP was reduced by H-89. 5. In conclusion, Ca2+ channel antagonism by glaucine appears mainly responsible for the relaxant effect of glaucine in human isolated bronchus while PDE4 inhibition contributes to the inhibitory effects of glaucine in human granulocytes. The very low PDE4/binding site ratio found for glaucine makes this compound attractive for further structure-activity studies. (+info)Mechanical effects of liriodenine on the left ventricular-arterial coupling in Wistar rats: pressure-stroke volume analysis. (2/80)
1. In a recent in vivo study, liriodenine, an aporphine alkaloid, has been identified as a prominent anti-arrhythmic agent that can prevent rats' sudden deaths, even at the dose as low as 10(-7) g kg(-1). The aim of this study was to determine whether liriodenine at its effective anti-arrhythmic dose of 10(-7) g kg(-1) had effects on the left ventricular (LV)-arterial coupling in Wistar rats. 2. LV pressure and ascending aortic flow signals were recorded to construct the ventricular and arterial end-systolic pressure-stroke volume relationships to calculate LV end-systolic elastance (E(es)) and effective arterial volume elastance (E(a)), respectively. The optimal afterload (Q(load)) determined by the ratio of E(a) to E(es) was used to measure the optimality of energy transmission from the left ventricle to the arterial system. 3. Liriodenine at the dose of 10(-7) g kg(-1) showed no significant changes in basal heart rate (HR), cardiac output (CO), LV end-systolic pressure (P(es)), E(a), E(es), and Q(load). 4. By contrast, liriodenine at the dose of 10(-6) g kg(-1) produced a significant fall of 2.0% in HR and a significant rise of 5.8% in CO, but no significant change in P(es). Moreover, liriodenine administration of 10(-6) g kg(-1) to rats significantly decreased E(es) by 8.5% and E(a) by 10.6%, but did not change Q(load). 5. We conclude that liriodenine at the dose of 10(-7) g kg(-1) has no effects on the mechanical properties of the heart and the vasculature and the matching condition for the left ventricle coupled to its vasculature in rats. Even at 10 times the effective anti-arrhythmic dose, liriodenine shows no effects on the efficiency of energy transferred from the left ventricle to the arterial system. (+info)Dicentrine is preferentially antagonistic to rat aortic than splenic alpha 1-adrenoceptor stimulation. (3/80)
AIM: Dicentrine is a known alpha 1-adrenoceptor antagonist, but its alpha 1-adrenoceptor subtype selectivity has not yet been determined. We therefore, investigated the putative alpha 1-adrenoceptor subtype selectivity of this agent. METHODS: Graded isometric contractile responses of rat aortic rings and spleen to phenylephrine were observed in the absence or presence of various concentrations of dicentrine. The pA2 values for dicentrine were determined. RESULTS: Aortic tissues were more sensitive to phenylephrine-induced contraction than the spleen tissues. Dicentrine was approximately 100 times more potent as an antagonist to the aortic contraction, than it was to the splenic contractions. CONCLUSION: Dicentrine is an alpha 1-adrenoceptor antagonist which is more selective towards the putative alpha 1D-adrenoceptor subtype of the rat aorta than the alpha 1B-adrenoceptor of the spleen. (+info)Multiple actions of glaucine on cyclic nucleotide phosphodiesterases, alpha 1-adrenoceptor and benzothiazepine binding site at the calcium channel. (4/80)
1. In the present study, the properties of glaucine (an aporphine structurally related to papaverine) were compared with those of papaverine, diltiazem, nifedipine and prazosin. The work includes functional studies on rat isolated aorta contracted with noradrenaline, caffeine or KCl, and a determination of the affinity of glaucine at calcium channel binding sites of alpha-adrenoceptors, by use of [3H]-(+)-cis-diltiazem, [3H]-nitrendipine and [3H]-prazosin binding to cerebral cortical membranes. The effects of glaucine on the different molecular forms of cyclic nucleotide phosphodiesterases (PDE) isolated from bovine aorta were also determined. 2. Contraction evoked by noradrenaline (1 microM) or depolarizing solution (60 mM KCl) were inhibited in a concentration-dependent manner by all the compounds tested. As expected, prazosin showed a greater selectivity of action on NA-induced contraction, whereas nifedipine and diltiazem appeared more potent on KCl-induced contraction. Glaucine had a greater potency on the contraction elicited by noradrenaline whereas papaverine acted non specifically. 3. In Ca(2+)-free solution, prazosin (0.1 microM) and glaucine (0.1 mM) inhibited the contraction evoked by NA; diltiazem (0.1 mM) diminished this contraction whereas nifedipine (1 microM) had no effect. Preincubation of tissues with glaucine, diltiazem, nifedipine and prazosin did not modify the contractile response induced by caffeine. In contrast, papaverine (0.1 mM) significantly inhibited the contractions evoked by NA or caffeine in Ca(2+)-free medium. 4. Glaucine and papaverine show affinity at the [3H]-prazosin binding site and at the benzothiazepine binding site of the Ca(2+)-channel receptor complex, but have no effect at the dihydropyridine binding site in rat cerebral cortex. Glaucine exerts some selectivity as an inhibitor of [3H]-prazosin binding as opposed to [3H]-(+ )-cis-diltiazem binding while papaverine appears to have approximately equal affinity in this respect.5. This study confirms the presence of four phosphodiesterase (PDE) activities in bovine aorta: a calmodulin-activated PDE (CaM-PDE type I) which hydrolyzed preferentially guanosine 3':5'-cyclic monophosphate (cyclic GMP); a cyclic GMP selective form (cGMP-PDE type V); and two low Km adenosine 3':5'-cyclic monophosphate (cyclic AMP) PDEs that are insensitive to the stimulatory effect of CaM, one of which was inhibited by cyclic GMP (CGI-PDE, type III) and the other by rolipram (cAMP-PDE, type IV). Glaucine selectively inhibits one of the two forms of Ca2+-independent low Km cAMP-PDE, the type IV. In contrast, papaverine exerts a non-selective inhibitory effect upon all PDE forms.6. The present work provides evidence that glaucine, a benzyltetrahydroisoquinoline alkaloid, has interesting properties as an alpha l-adrenoceptor antagonist, calcium entry blocker (through the benzothiazepine recognition site in the calcium channel) and as a selective inhibitor of the rolipram-sensitive cAMP-PDE, type IV PDE. (+info)Haemodynamic effects of dicentrine, a novel alpha 1-adrenoceptor antagonist: comparison with prazosin in spontaneously hypertensive and normotensive Wistar-Kyoto rats. (5/80)
1. The haemodynamic effects of dicentrine, an aporphine derivative isolated from the plant Lindera megaphylla, were investigated and compared with prazosin in rats. 2. In anaesthetized normotensive Wistar-Kyoto (WKY) rats, i.v. administration of dicentrine (0.1, 0.5, 1.0 mg kg-1) and prazosin (0.01, 0.05, 0.1 mg kg-1) induced a dose-related reduction of mean arterial pressure (MAP) which reached a maximal effect 5-10 min after injection and persisted for 2 h. 3. In anaesthetized WKY rats, a higher dose of dicentrine (1.0 mg kg-1, i.v.) did not cause any significant changes in heart rate (HR), cardiac output (CO) and stroke volume (SV) but markedly increased tail blood flow. In contrast, a higher dose of prazosin (0.1 mg kg-1, i.v.) produced a decrease in HR which paralleled the time course of the hypotensive response. 4. The hypotensive activity of dicentrine was completely abolished by alpha-adrenoceptor blockade. Both dicentrine and prazosin significantly attenuated pressor responses to noradrenaline but failed, even at maximal hypotensive doses, to impair the pressor effects of angiotensin II or vasopressin. These observations suggest that dicentrine appears to exert its hypotensive action through alpha 1-adrenoceptor blockade. 5. In conscious normotensive and spontaneously hypertensive (SH) rats, dicentrine (0.5-2.0 mg kg-1, i.v.) and prazosin (0.05-0.2 mg kg-1, i.v.) also evoked dose-related decreases in MAP which were of greater magnitude in SH rats. Oral administration of dicentrine (5 and 8 mg kg-1) to conscious SH rats caused a hypotensive effect which persisted for over 15 h.6. These results suggest that dicentrine may have therapeutic potential as an oral antihypertensive drug via alpha-adrenoceptor blockade. (+info)Reactive oxygen species (ROS) generation inhibited by aporphine and phenanthrene alkaloids semi-synthesized from natural boldine. (6/80)
Four phenanthrene and one aporphine alkaloids semi-synthesized from boldine were evaluated for their inhibitory effect on reactive oxygen species (ROS) generation. ROS generation by neutrophils stimulated with N-formyl-methionyl-leucyl-phenylalanine was inhibited in a concentration dependent manner. Alkaloids exerted similar inhibitory effect in the hypoxanthine-xanthine oxidase system than in stimulated neutrophils, which could be attributed to a direct ROS scavenging activity. None of the alkaloids assayed had any effect on xanthine oxidase activity. Therefore the synthesized alkaloids might constitute an alternative therapy in inflammation disorders in which ROS generation is involved. (+info)Effect of boldine, secoboldine, and boldine methine on angiotensin II-induced neutrophil recruitment in vivo. (7/80)
Angiotensin-II (Ang-II) has inflammatory activity and is involved in different diseases associated with the cardiovascular system. This study has evaluated the effect of boldine (B), and two phenanthrene alkaloids semisynthesized by us, secoboldine (SB) and boldine methine (BM), on Ang-II-induced neutrophil recruitment. Intraperitoneal administration of 1 nM Ang-II induced significant neutrophil accumulation, which was maximal at 4-8 h. BM inhibited neutrophil infiltration into the peritoneal cavity at 4 h and 8 h by 73% and 77%, respectively, SB at 8 h by 55%, and B had no effect on this response. Although BM inhibited the release of cytokine-inducible neutrophil chemoattractant/keratinocyte-derived chemokine, macrophage inflammatory protein-2 (MIP-2), and platelet-activating factor (PAF) elicited by Ang-II, SB only reduced the release of MIP-2 after 4 h of its administration. Sixty-minute superfusion of the rat mesentery with 1 nM Ang-II induced a significant increase in the leukocyte-endothelial cell interactions and P-selectin up-regulation, which were inhibited by 1 microM BM and SB. The generation of reactive oxygen species (ROS) in endothelial cells stimulated with Ang-II was inhibited significantly by the three alkaloids tested. BM also diminished Ang-II-induced interleukin-8 release from endothelial cells and blocked the PAF receptor on human neutrophils (concentration of the compound needed to produce 50% inhibition value: 28.2 microM). Therefore, BM is a potent inhibitor of Ang-II-induced neutrophil accumulation in vivo. This effect appears to be mediated through inhibition of CXC chemokine and PAF release, ROS scavenging activity, and blockade of the PAF receptor. Thus, it may have potential therapeutic interest for the control of neutrophil recruitment that occurs in inflammation associated with elevated levels of Ang-II. (+info)Characterization and inhibitor discovery of one novel malonyl-CoA: acyl carrier protein transacylase (MCAT) from Helicobacter pylori. (8/80)
Type II fatty acid synthesis (FAS II) is an essential process for bacteria survival, and malonyl-CoA:acyl carrier protein transacylase (MCAT) is a key enzyme in FAS II pathway, which is responsible for transferring the malonyl group from malonyl-CoA to the holo-ACP by forming malonyl-ACP. In this work, we described the cloning, characterization and enzymatic inhibition of a new MCAT from Helicobacter pylori strain SS1 (HpMCAT), and the gene sequence of HpfabD was deposited in the GenBank database (Accession No. AY738332 ). Enzymatic characterization of HpMCAT showed that the K(m) value for malonyl-CoA was 21.01+/-2.3 microM, and the thermal- and guanidinium hydrochloride-induced unfolding processes for HpMCAT were quantitatively investigated by circular dichroism spectral analyses. Moreover, a natural product, corytuberine, was discovered to demonstrate inhibitory activity against HpMCAT with IC(50) value at 33.1+/-3.29 microM. Further enzymatic assay results indicated that corytuberine inhibits HpMCAT in an uncompetitive manner. To our knowledge, this is the firstly reported MCAT inhibitor to date. This current work is hoped to supply useful information for better understanding the MCAT features of H. pylori strain, and corytuberine might be used as a potential lead compound in the discovery of the antibacterial agents using HpMCAT as target.

... 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] ...
EA-3443
... 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 ...

2C-E
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. ...
Nalorphine
... (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 ...
N-Ethyl-3-piperidyl benzilate
... (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 ...
Phenyltoloxamine
... 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 ...

The effects of dissociatives can include sensory dissociation, hallucinations, mania, catalepsy, analgesia and amnesia.[5][6][7] The characteristic features of dissociative anesthesia were described as catalepsy, amnesia and analgesia.[5] According to Pender (1972), "the state has been designated as dissociative anesthesia since the patient truly seems disassociated from his environment."[8] Bonta (2004) described dissociative anaesthesia as "... a peculiar anaesthetic state in which marked sensory loss and analgesia as well as amnesia is not accompanied by actual loss of consciousness."[9] Both Pender (1970) and Johnstone et al. (1959) reported that patients under anaesthesia due to either ketamine or phencyclidine were prone to purposeless movements and had hallucinations (or "dreams"[10]) during and after anaesthesia. Some patients found the hallucinations euphoric while others found them disturbing. At sub-anesthetic doses, dissociatives alter many of the same cognitive and perceptual ...
2,5-Dimethoxy-4-bromoamphetamine
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] ...
5,N-Dimethyl-N-isopropyltryptamine
... (5-Me-MiPT) is a tryptamine derivative that is thought to be a psychedelic drug. It was first made in 1989. In vitro binding experiments on brain homogenates showed it to have a binding affinity between that of MiPT and 5-MeO-MiPT,[1] both of which are known to be active psychedelics in humans.. ...
5-Methyl-MDA
Drug discrimination studies showed that 5-methyl-MDA substitutes for MDA, MMAI, and LSD, but not amphetamine, suggesting that it produces a mix of entactogen and hallucinogenic effects without any stimulant effects.[2]. 5-Methyl-MDA acts as a selective serotonin releasing agent (SSRA) with IC50 values of 107nM, 11,600nM, and 1,494nM for serotonin, dopamine, and norepinephrine efflux.[1] It is over 5x more potent than MDA, with a suitable active dose possibly being around 15-25 mg.[1][2] Subsequent testing, however, has found that it is not as potent as once thought and is active at at least 100mg. 2-Methyl-MDA is also much more potent than MDA, but is not quite as potent as 5-methyl-MDA.[1] 6-methyl-MDMA (also known as Madam-6) is mostly inactive, likely due to steric hindrance.[1][3]. Recent research has used data on 2-methyl-MDA and 5-methyl-MDA to help guide computer modeling of the serotonin transporter complex.[4]. ...
Pentazocine
... ,[2] sold under the brand name Talwin among others, is a painkiller used to treat moderate to severe pain. It is believed to work by activating (agonizing) κ-opioid receptors (KOR) and blocking (antagonizing) μ-opioid receptors (MOR). As such it is called an opioid as it delivers its effects on pain by interacting with the opioid receptors. It shares many of the side effects of other opioids like constipation, nausea, itching, drowsiness and respiratory depression, but unlike most other opioids it fairly frequently causes hallucinations, nightmares and delusions. It is also, unlike most other opioids, subject to a ceiling effect, which is when at a certain dose (which differs from person-to-person) no more pain relief, or side effects, is obtained by increasing the dose any further.[3] Chemically it is classed as a benzomorphan and it comes in two enantiomers, which are molecules that are exact (non-superimposable) mirror images of one another. It was patented in 1960 and approved ...
PCPr
... is an arylcyclohexylamine dissociative anesthetic drug with hallucinogenic and stimulant effects. It is around the same potency as phencyclidine, although slightly less potent than its ethyl homologue eticyclidine,[1] and has reportedly been sold as a designer drug in Germany and other European countries since the late 1990s.[2][3] Several other related derivatives have also been encountered, with the n-propyl group of PCPr replaced by a 2-methoxyethyl, 2-ethoxyethyl or 3-methoxypropyl group to form PCMEA, PCEEA and PCMPA respectively.[4][5][6] ...

Ergoline
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 ...
2,5-Dimethoxy-4-propylamphetamine
... (DOPR) is a psychedelic drug of the phenethylamine and amphetamine chemical classes. It was first synthesized by Alexander Shulgin, and was described in his book PiHKAL (Phenethylamines i Have Known And Loved). Shulgin described DOPR is a "heavy duty psychedelic", complete with alterations of the thought process and visual distortion.[1] Very little data exists about the pharmacological properties, metabolism, and toxicity of DOPR. The alternative structural isomer DOIP, with a 4-isopropyl substitution, is also known but is around ten times weaker than DOPR, with an active dose of some 20-30 mg (as compared to 2-5 mg for DOPR).[1] ...
5-Bromo-DMT
... (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] ...
4-Acetoxy-DiPT
Sveriges riksdags health ministry Statens folkhälsoinstitut classified 4-AcO-DiPT as "health hazard" under the act Lagen om förbud mot vissa hälsofarliga varor (translated Act on the Prohibition of Certain Goods Dangerous to Health) as of Mar 1, 2005, in their regulation SFS 2005:26 listed as 4-acetoxi-N,N-diisopropyltryptamin (4-AcO-DIPT), making it illegal to sell or possess.[3] ...

Dimethyllysergamide
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] ...
2,5-Dimethoxy-4-(2-fluoroethyl)amphetamine
... (DOEF), also known as dimethoxyfluoroethylamphetamine, is a lesser-known psychedelic drug and member of the DOx class.[1][2] DOEF was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage range is listed as 2-3.5 mg, and the duration is listed as 12-16 hours.[3] Very little data exists about the pharmacological properties, metabolism, and toxicity of DOEF. ...
Levonantradol
... 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 ...
Tolterodine
... 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] ...
25TFM-NBOMe
... (also known as NBOMe-2C-TFM, 2C-TFM-NBOMe, and Cimbi-138) is a derivative of the phenethylamine hallucinogen 2C-TFM, discovered in 2004 by Ralf Heim at the Free University of Berlin.[1] It acts as a potent partial agonist for the 5HT2A receptor, though its relative potency is disputed, with some studies finding it to be of lower potency than 25I-NBOMe,[2][3] while others show it to be of similar or higher potency,[4] possibly because of differences in the assay used.[5] 2C-TFM-NB2OMe can be taken to produce psychedelic effects similar to 2C-I-NB2OMe and 2C-D-NB2OMe. ...
