Indole-based alkaloidsXuefenginsXuefenglasinsCytotoxicitySeven undescribed indole-based alkaloids, xuefengins A–D and xuefenglasins A–C, were isolated from natural Ophiocordyceps xuefengensis, along with six known alkaloids. Their structures were elucidated by comprehensive spectroscopy, with absolute ...
and 3R/S-hydroxytabernanthine (180), along with the previously known indole alkaloids voacangine (27), isovoacangine (181), coronaridine (182), 11-hydroxycoronaridine (183), voacristine (184), 19-epi-voacristine (185), isovoacristine (186), ibogamine (187), 10-...
The indole alkaloids are aromatic heterocyclic organic compounds which have a bicyclic structure consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring [48]. From: Fitoterapia, 2013 About this pageSet alert ...
Unregulated serotonin levels can lead to depression, and both synthetic and plant-based indole alkaloids have been investigated for use in antidepressant drugs (Hamid et al. 2017). Plant-based indoles such as psilocybin and dimethyltryptamine are attracting growing interest as potential treatment for ...
Indole alkaloids from the roots ofIsatis ingigoticaand their antiherpes simplex virus type 2 (HSV-2) activityin vitro A new indole alkaloid 1, together with four known indole alkaloids 2–5, was isolated from the 95% EtOH extract of the traditional Chinese medicinal plant ... DD Sun,WW ...
摘要: The first total synthesis of indole alkaloid (±)-subincanadine E has been accomplished. Ni(COD)2-mediated intramolecular Michael addition and zinc-mediated fragmentation reaction served as two key transformations.关键词: Aspidosperma Indole Alkaloids Nuclear Magnetic Resonance, Biomolecular ...
Further brominated bis- and tris-indole alkaloids from the deep-water New Caledonian marine sponge Orina Sp. Two tris-indole alkaloids, (+/-) gelliusines A and B [1], have been isolated for the first time from a marine source, the New Caledonian sponge, Orina sp. (or Gellius sp.), ...

alkaloids[2]. The biological properties of these molecules attracted the attention of chemists and led to the first isolation of a monoterpeneindole alkaloid,strychnine(Scheme 1.1), by Pelletier and Caventou in 1819[3]. Based on the contributions of many laboratories, over the past 200 years ...
Alkaloids are a large cluster of molecules found in Mother Nature all over the world. They are all secondary compounds and collection of miscellaneous elements and biomolecules, derived from amino acids or from transamination. This diverse chemical group is categorized, based on the amino acids that...
