Tochergamine
Tochergamine, also known as 621 I.S. or as ''N'',''N''-diethyl-''N''′-(1,2,3,4-tetrahydronaphthyl)glycinamide, is an oxytocic drug related to ergometrine which does not appear to have been marketed. It was reported to be effective as an oxytocic agent in animal studies, with oxytocic activity equivalent to that of ergometrine. In addition, the drug was reported to be effective in clinical studies at doses of 2 to 6mg parenterally. However, subsequent research found that it was inactive on the intact human uterus at doses of up to 20mg, and further investigation of tochergamine was abandoned. Tochergamine has a simplified lysergamide-like chemical structure, with a 1-aminotetralin ring system, and is structurally related to lysergamides like ergometrine and LSD. However, it is not technically a partial ergoline or lysergamide, only partial ergoline-like, as its structural features differ in certain regards from those of ergolines and lysergamides. The oxytocic effects of lyse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Partial Ergoline
Partial or simplified ergolines and lysergamides are structural analog, analogues of ergolines and substituted lysergamide, lysergamides like LSD in which one or more atoms or covalent bond, bonds, for instance within the ergoline ring system (chemistry), ring system, have been removed. Additional chemical substituent, substitutions may also be added, for instance on the A ring of the ergoline nucleus. It is notable that the ergoline ring system contains embedded substituted tryptamine, tryptamine and substituted phenethylamine, phenethylamine moiety (chemistry), moieties within its chemical structure, structure, and so some partial ergolines are simple tryptamines, cyclized tryptamines, simple phenethylamines, and/or cyclized phenethylamines. In terms of pharmacology, partial lysergamides include serotonin receptor agonist, serotonin and dopamine receptor agonists. Some, like NDTDI, DEMPDHPCA, DEIMDHPCA, and LPH-5 (drug), LPH-5, are serotonin 5-HT2A receptor, 5-HT2A receptor agon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

5-HT2 Receptor
The 5-HT2 receptors are a subfamily of 5-HT receptors that bind the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). The 5-HT2 subfamily consists of three G protein-coupled receptor G protein-coupled receptors (GPCRs), also known as seven-(pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptors, and G protein-linked receptors (GPLR), form a large group of evolutionarily related ...s (GPCRs) which are coupled to Gq/G11 and mediate excitatory neurotransmission, including 5-HT2A, 5-HT2B, and 5-HT2C.

David E
David (; , "beloved one") was a king of ancient Israel and Judah and the third king of the United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as " House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the '' Seder Olam Rabbah'', '' Seder Olam Zutta'', and '' Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, the historicity of which has been extensively challenged,Writing and Rewriting the Story of Solomon in Ancient Israel; by Isaac Kalimi; pa ...

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 '' Argyreia nervosa'' ( Hawaiian baby woodrose), and ''Ipomoea'' species ( morning glories, ololiuhqui, tlitliltzin). Amides of lysergic acid, lysergamides, are widely used as pharmaceuticals and as psychedelic drugs, e.g. lysergic acid diethylamide (LSD). Lysergic acid is listed as a Table I precursor under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. The name Lysergic acid comes from the fact that it is a carboxylic acid, and it was first made by hydrolysis of various ergot alkaloids. Synthesis Laboratory 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Positional Isomer
In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature) of a compound is a compound that contains the same number and type of atoms, but with a different connectivity (i.e. arrangement of bonds) between them. The term metamer was formerly used for the same concept. For example, butanol , methyl propyl ether , and diethyl ether have the same molecular formula but are three distinct structural isomers. The concept applies also to polyatomic ions with the same total charge. A classical example is the cyanate ion and the fulminate ion . It is also extended to ionic compounds, so that (for example) ammonium cyanate and urea are considered structural isomers,William F. Bynum, E. Janet Browne, Roy Porter (2014)''Dictionary of the History of Science'' page 218. and so are methylammonium formate and ammonium acetate . Structural isomerism is the most radical type of isomerism. It is opposed to stereoisomerism, in which the atoms and bonding s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-aminotetralin
2-Aminotetralin (2-AT), also known as 1,2,3,4-tetrahydronaphthalen-2-amine (THN), is a stimulant drug with a chemical structure consisting of a tetralin core with an amine as substituent. 2-AT is a rigid analogue of phenylisobutylamine and fully substitutes for d-amphetamine in rat drug discrimination tests, although at one-half to one-eighth the potency. It showed greater potency than a variety of other amphetamine homologues, including 2-amino-1,2-dihydronapthalene (2-ADN), 2-aminoindane (2-AI), 1-naphthylaminopropane (1-NAP), 2-naphthylaminopropane (2-NAP), 1-phenylpiperazine (1-PP), , and . 2-AT has been shown to inhibit the reuptake of serotonin and norepinephrine, and might induce their release as well. It is also likely to act on dopamine on account of its full substitution of d-amphetamine in rodent studies. Chemical derivatives A number of derivatives of 2-aminotetralin exist, including: See also * 1-Aminotetralin 1-Aminotetralin (1-AT), also known as ...

Structural Analog
A structural analog, also known as a chemical analog or simply an analog, is a chemical compound, compound having a chemical structure, structure similar to that of another compound, but differing from it in respect to a certain component. It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or substructures. A structural analog can be imagined to be formed, at least theoretically, from the other compound. Structural analogs are often isoelectronicity, isoelectronic. Despite a high chemical similarity, structural analogs are not necessarily functional analog (chemistry), functional analogs and can have very different physical, chemical, biochemical, or pharmacological properties. In drug discovery, either a large series of structural analogs of an initial lead compound are created and tested as part of a structure–activity relationship study or a database is virtual screening, screened for structural analogs of a ...
