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 کاملStreptopyridines, volatile pyridine alkaloids produced by Streptomyces sp. FORM5
Streptomyces sp. FORM5 is a bacterium that is known to produce the antibiotic streptazolin and related compounds. We investigated the strain for the production of volatiles using the CLSA (closed-loop stripping analysis) method. Liquid and agar plate cultures revealed the formation of new 2-alkylpyridines (streptopyridines), structurally closely related to the already known 2-pentadienylpiperid...
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 کاملEXTRACTION AND ISOLATION OF INDOLE ALKALOIDS FROM Tabernaemontana catharinensis: TECHNICAL AND ECONOMICAL ANALYSIS
Leishmaniasis is a parasitic infection that is considered worldwide one of the most important public health problem, affecting more than 12 million people with an estimated number of 2 million new cases occurring annually. Among the compounds isolated from Tabernaemontana catharinensis, coronaridine and voacangine are the indole alkaloids which have antileishmanial activity. In this work, the t...
