Lysergic Acid 2-butyl Amide
Lysergic acid 2-butyl amide (2-Butyllysergamide, LSB) is an analogue of LSD originally developed by Richard Pioch at Eli Lilly in the 1950s, but mostly publicised through research conducted by the team led by David E. Nichols at Purdue University. It is a structural isomer of LSD, with the two ethyl groups on the amide nitrogen having been replaced by a single sec-butyl group, joined at the 2-position. It is one of the few lysergamide derivatives to exceed the potency of LSD in animal drug discrimination assays, with the (R) isomer having an ED50 of 33nmol/kg for producing drug-appropriate responding, vs 48nmol/kg for LSD itself. The corresponding (R)-2-pentyl analogue has higher binding affinity for the 5-HT1A and 5-HT2A receptors, but is less potent in producing drug-appropriate responding, suggesting that the butyl compound has a higher efficacy at the receptor target. The drug discrimination assay for LSD in rats involves both 5-HT1A and 5-HT2A mediated components, and whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methysergide
Methysergide, sold under the brand names Deseril and Sansert, is a monoaminergic medication of the ergoline and lysergamide groups which is used in the prophylaxis and treatment of migraine and cluster headaches. It has been withdrawn from the market in the United States and Canada due to adverse effects. It is taken by mouth. Methysergide is no longer recommended as a first line treatment protocol by international headache societies, hospitals, and neurologists in private practice, for migraines or cluster headaches as side effects were first reported with long-term use in the late 1960s, and ergot-based treatments fell out of favor for the treatment of migraines with the introduction of triptans in the 1980s. Medical uses Methysergide is used exclusively to treat episodic and chronic migraine and for episodic and chronic cluster headaches. Methysergide is one of the most effective medications for the prevention of migraine, but is not intended for the treatment of an acute atta ...

Ergine
Ergine, also known as d-lysergic acid amide (LSA) and d-lysergamide, is an ergoline alkaloid that occurs in various species of vines of the Convolvulaceae and some species of fungi. The psychedelic properties in the seeds of ololiuhqui, Hawaiian baby woodrose and morning glories have been linked to ergine and/or isoergine, its epimer, as it is an alkaloid present in the seeds. Occurrence in nature Ergine has been found in high concentrations of 20 μg/g dry weight in the sleepygrass infected with an ''Acremonium'' endophytic fungus together with other ergot alkaloids. Ergine is a component of the alkaloids contained in the ergot fungus, which grows on the heads of infected rye grasses. It is also found in the seeds of several varieties of morning glories in concentrations of approximately 10 μg per seed, as well as Hawaiian baby woodrose seeds, at a concentration of around 0.13% of dry weight.

DAM-57
''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. This compound did induce autonomic disturbances at oral levels of some ten times the dosage required for LSD Lysergic acid diethylamide (LSD), also known colloquially as acid, is a potent psychedelic drug. Effects typically include intensified thoughts, emotions, and sensory perception. At sufficiently high dosages LSD manifests primarily mental, vi ..., presumably in the high hundreds of micrograms.

Lysergic Acid
Lysergic acid, also known as -lysergic acid and (+)-lysergic acid, is a precursor for a wide range of ergoline alkaloids that are produced by the ergot fungus and found in the seeds of '' Turbina corymbosa'' (ololiuhqui), '' Argyreia nervosa'' (Hawaiian baby woodrose), and ''Ipomoea tricolor'' (morning glories, tlitliltzin). Amides of lysergic acid, lysergamides, are widely used as pharmaceuticals and as psychedelic drugs (LSD). Lysergic acid is listed as a Table I precursor under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. Lysergic acid received its name as it was a product of the lysis of various ergot alkaloids. Total synthesis Lysergic acid is generally produced by hydrolysis of natural lysergamides, but can also be synthesized in the laboratory by a complex total synthesis, for example by Robert Burns Woodward's team in 1956. An enantioselective total synthesis based on a palladium-catalyzed domino cyclization r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amesergide
Amesergide (, ; developmental code name LY-237733) is a serotonin receptor antagonist of the ergoline and lysergamide families related to methysergide which was under development by Eli Lilly and Company for the treatment of a variety of conditions including depression, anxiety, schizophrenia, male sexual dysfunction, migraine, and thrombosis but was never marketed.Pertz, H. E. I. N. Z., & Eich, E. C. K. A. R. T. (1999). Ergot alkaloids and their derivatives as ligands for serotoninergic, dopaminergic, and adrenergic receptors. Ergot: the genus Claviceps. Harwood Academic Publishers, Amsterdam, The Netherlands, 411-440. It reached phase II clinical trials for the treatment of depression, erectile dysfunction, and premature ejaculation prior to the discontinuation of its development. Pharmacology Pharmacodynamics Amesergide acts as a selective antagonist of the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors (Ki = 1.96–15.1 nM). It is also an antagonist of the seroton ...

Methergine
Methylergometrine, also known as methylergonovine and sold under the brand name Methergine, is a medication of the ergoline and lysergamide groups which is used as an oxytocic in obstetrics and in the treatment of migraine. It reportedly produces psychedelic effects similar to those of lysergic acid diethylamide (LSD) at high doses. It is on the World Health Organization's List of Essential Medicines. Medical uses Obstetric use Methylergometrine is a smooth muscle constrictor that mostly acts on the uterus. It is most commonly used to prevent or control excessive bleeding following childbirth and spontaneous or elective abortion, and also to aid in expulsion of retained products of conception after a missed abortion (miscarriage in which all or part of the fetus remains in the uterus) and to help deliver the placenta after childbirth. It is available as tablets or injection ( IM or IV) or in liquid form to be taken orally. Migraine Methylergometrine is sometimes used for both ...

LAE-32
D-Lysergic acid ethylamide (LAE-32) is a derivative of ergine. It is reported to have some LSD-like effects but is weaker and shorter lasting, with an active dose reported to be between 0.5 and 1.5 milligrams. It was studied by the CIA as part of Project MKULTRA. Documents published by the CIA under the Freedom of Information Act suggest it causes "a schizophrenia-like condition" but it allows people with schizophrenia Schizophrenia is a mental disorder characterized by continuous or relapsing episodes of psychosis. Major symptoms include hallucinations (typically hearing voices), delusions, and disorganized thinking. Other symptoms include social w ... to remain indifferent to their disorder.

Ergometrine
Ergometrine, also known as ergonovine and sold under the brand names Ergotrate, Ergostat, and Syntometrine among others, is a medication used to cause contractions of the uterus to treat heavy vaginal bleeding after childbirth. It can be used either by mouth, by injection into a muscle, or injection into a vein. It begins working within 15 minutes when taken by mouth and is faster in onset when used by injection. Effects last between 45 and 180 minutes. Common side effect include high blood pressure, vomiting, seizures, headache, and low blood pressure. Other serious side effects include ergotism. It was originally made from the rye ergot fungus but can also be made from lysergic acid. Ergometrine is regulated because it can be used to make lysergic acid diethylamide (LSD). Ergometrine was discovered in 1932. It is on the World Health Organization's List of Essential Medicines.
