(R)-69
(''R'')-69 (3IQ) is a tetrahydropyridine derivative which acts as a 5-HT2A receptor agonist, with 4.6-fold selectivity over 5-HT2B and 49-fold selectivity over 5-HT2C. It has a 5-HT2A Ki of 680 nM and an EC50 of 41 nM. (''R'')-69 is a biased agonist selective for activation of the Gq coupled signalling pathway, with much weaker activation of the β-arrestin 2 coupled pathway. In animal studies it produces antidepressant-like activity but without producing the head-twitch response associated with psychedelic effects.

BW-723C86
BW-723C86 is a tryptamine derivative drug which acts as a 5-HT2B receptor agonist. It has anxiolytic effects in animal studies, and is also used for investigating the function of the 5-HT2B receptor in a range of other tissues. BW-723C86 is actually a mixed 5-HT2B/5-HT2C agonist, and while it has good selectivity over 5-HT2A and other serotonin receptor subtypes, it is around only 3 times as selective for 2B compared to 2C and so is much less selective than most research ligands, but no superior 5-HT2B agonist was available until the potent and selective 5-HT2B activity of 6-APB was discovered in 2012. Highly selective 5-HT2C antagonists are available however, and so a combination of BW-723C86 with a selective 5-HT2C antagonist allows 5-HT2B mediated responses to be studied in isolation. The drug does not induce the head-twitch response, a behavioral proxy of psychedelic effects associated with serotonin 5-HT2A receptor agonism, across a wide range of doses. This may be relate ...

5-HT2B Receptor
5-Hydroxytryptamine receptor 2B (5-HT2B) also known as serotonin receptor 2B is a protein that in humans is encoded by the ''HTR2B'' gene. 5-HT2B is a member of the 5-HT2 receptor, 5-HT2 receptor family that binds the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Like all 5-HT2 receptors, the 5-HT2B receptor is Gq protein, Gq/G11-protein coupled, leading to downstream activation of phospholipase C. Tissue distribution and function First discovered in the stomach of rats, 5-HT2B was challenging to characterize initially because of its structural similarity to the other 5-HT2 receptors, particularly 5-HT2C. The 5-HT2 receptors (of which the 5-HT2B receptor is a subtype) mediate many of the central and peripheral physiologic functions of serotonin. Cardiovascular effects include contraction of blood vessels and shape changes in platelets; central nervous system (CNS) effects include neuronal sensitization to tactile stimuli and mediation of some of the effects of halluci ...

RU-28253
RU-28253 is a non-selective serotonin receptor agonist of the tryptamine and 5-methoxytryptamine families. It is a tetrahydropyridylindole and a conformationally constrained analogue of 5-MeO-DMT. The drug shows high affinity for the serotonin 5-HT1A receptor (Ki = 5.7nM) and lower affinity for the serotonin 5-HT2A receptor (Ki = 230nM). Its affinities for these receptors were higher than those of dimethyltryptamine (DMT). RU-28253 is described as a potent agonist of the serotonin 5-HT1 and 5-HT2 receptors, including of the serotonin 5-HT1B receptor, and is also an agonist of the serotonin 5-HT4 receptor. RU-28253 was first described in the scientific literature by 1983.

Indazoles
Indazole, also called isoindazole, is a heterocyclic aromatic organic compound. This bicyclic compound consists of the fusion of benzene and pyrazole. Indazole is an amphoteric molecule which can be protonated to an indazolium cation or deprotonated to an indazolate anion. The corresponding ''pKa'' values are 1.04 for the equilibrium between indazolium cation and indazole and 13.86 for the equilibrium between indazole and indazolate anion. Indazole derivatives display a broad variety of biological activities. Indazoles are rare in nature. The alkaloids nigellicine, nigeglanine, and nigellidine are indazoles. Nigellicine was isolated from the widely distributed plant '' Nigella sativa'' L. (black cumin). Nigeglanine was isolated from extracts of '' Nigella glandulifera''. The Davis–Beirut reaction can generate 2''H''-indazoles. Indazole, C7H6N2, was obtained by E.

Serotonin Receptor Agonists
A serotonin receptor agonist is an agonist of one or more serotonin receptors. They activate serotonin receptors in a manner similar to that of serotonin (5-hydroxytryptamine; 5-HT), a neurotransmitter and hormone and the endogenous ligand of the serotonin receptors. Non-selective agonists Serotonergic psychedelics such as tryptamines (e.g., psilocybin, psilocin, , 5-MeO-DMT, bufotenin), lysergamides (e.g., , ergine ()), phenethylamines (e.g., mescaline, 2C-B, 25I-NBOMe), and amphetamines (e.g., , ) are non-selective agonists of serotonin receptors. Their hallucinogenic effects are specifically mediated by activation of the 5-HT2A receptor. Drugs that increase extracellular serotonin levels such as serotonin reuptake inhibitors (e.g., fluoxetine, venlafaxine), serotonin releasing agents (e.g., fenfluramine, ), and monoamine oxidase inhibitors (e.g., phenelzine, moclobemide) are indirect non-selective serotonin receptor agonists. They are used variously as an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5-HT2B Agonists
Serotonin (), also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter with a wide range of functions in both the central nervous system (CNS) and also peripheral tissues. It is involved in mood, cognition, reward, learning, memory, and physiological processes such as vomiting and vasoconstriction. In the CNS, serotonin regulates mood, appetite, and sleep. Most of the body's serotonin—about 90%—is synthesized in the gastrointestinal tract by enterochromaffin cells, where it regulates intestinal movements. It is also produced in smaller amounts in the brainstem's raphe nuclei, the skin's Merkel cells, pulmonary neuroendocrine cells, and taste receptor cells of the tongue. Once secreted, serotonin is taken up by platelets in the blood, which release it during clotting to promote vasoconstriction and platelet aggregation. Around 8% of the body's serotonin is stored in platelets, and 1–2% is found in the CNS. Serotonin acts as both a vasoconstrictor and v ...

6-APB
6-APB (6-(2-aminopropyl)benzofuran) is an empathogenic psychoactive drug of the substituted benzofuran and substituted phenethylamine classes. 6-APB and other compounds are sometimes informally called "Benzofury" in newspaper reports. It is similar in structure to MDA, but differs in that the 3,4- methylenedioxyphenyl ring system has been replaced with a benzofuran ring. 6-APB is also the unsaturated benzofuran derivative of 6-APDB. It may appear as a tan grainy powder. While the drug never became particularly popular, it briefly entered the rave and underground clubbing scene in the UK before its sale and import were banned. It falls under the category of research chemicals, sometimes called "legal highs” if uncontrolled. Because 6-APB and other substituted benzofurans have not been explicitly outlawed in some countries, they are often technically legal, contributing to its popularity. Use 6-APB can be found in freebase, hydrochloride, and succinate form. The free ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agonist
An agonist is a chemical that activates a Receptor (biochemistry), receptor to produce a biological response. Receptors are Cell (biology), cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an Receptor antagonist, antagonist blocks the action of the agonist, while an inverse agonist causes an action opposite to that of the agonist. Etymology The word originates from the Ancient Greek, Greek word (''agōnistēs''), "contestant; champion; rival" < (''agōn''), "contest, combat; exertion, struggle" < (''agō''), "I lead, lead towards, conduct; drive." Types of agonists Receptor (biochemistry), Receptors can be activated by either endogenous agonists (such as hormones and neurotransmitters) or exogenous agonists (such as medication, drugs), resulting in a biological response.
