Indole Alkaloids from Chaetomium globosum.
Two new indole alkaloids chaetocochin J (1) and chaetoglobinol A (8), along with chetomin (2), chetoseminudin A (3), cochliodinol (9), and semicochliodinol (10), were isolated from the rice culture of the fungus Chaetomium globosum. Their structures were elucidated by spectral analysis. Three new epipolythiodioxopiperazines, chaetocochins G-I (5-7), were identified by the combination of UPLC an...
متن کاملAntitussive indole alkaloids from Kopsia hainanensis.
Three new indole alkaloids, named kopsihainins A-C (1-3), and two known compounds, kopsinine (4) and methyl demethoxycarbonylchanofruticosinate (5), were isolated from the stems of Kopsia hainanensis. Their structures were determined using extensive spectroscopic methods. The two main constituents 4 and 5 exhibited significant antitussive activity in a citric acid induced guinea pig cough model...
متن کاملHalogenated Indole Alkaloids from Marine Invertebrates
This review discusses the isolation, structural elucidation, and biological activities of halogenated indole alkaloids obtained from marine invertebrates. Meridianins and related compounds (variolins, psammopemmins, and aplicyanins), as well as aplysinopsins and leptoclinidamines, are focused on. A compilation of the (13)C-NMR spectral data of these selected natural indole alkaloids is also pro...
متن کاملMarine Indole Alkaloids
Marine indole alkaloids comprise a large and steadily growing group of secondary metabolites. Their diverse biological activities make many compounds of this class attractive starting points for pharmaceutical development. Several marine-derived indoles were found to possess cytotoxic, antineoplastic, antibacterial and antimicrobial activities, in addition to the action on human enzymes and rec...
متن کاملPrenylated indole diketopiperazine alkaloids, spiro-
Peroxy-containing metabolitesare an interesting group amongbiological active natural compounds. These metabolites contain a peroxide group (-O-O-) in which each oxygen atom is bonded to the other oxygen an to another atom. β-Oxygen in hydroperoxide group is considered as moreactive.Present review describes research on more than 100 natural hydroperoxidesand rare acyclic peroxides isolated from ...
