Abstract
Ouhanamide (1), a new linear lipopeptide consisting of a long-chain fatty acid with a β-branched methyl group, was isolated from a marine Okeania sp. cyanobacterium. The overall structure was elucidated by a combination of various spectroscopic analyses, degradation reactions, and derivatizations. Ouhanamide (1) showed selective antiparasitic activity (IC50 = 1.2 ± 0.1 μM against Trypanosoma brucei rhodesiense and IC50 = 4.2 ± 0.9 μM against Plasmodium falciparum) without cytotoxicity at 10 μM against HeLa cells.
期刊介绍:
The Journal of Natural Products invites and publishes papers that make substantial and scholarly contributions to the area of natural products research. Contributions may relate to the chemistry and/or biochemistry of naturally occurring compounds or the biology of living systems from which they are obtained.
Specifically, there may be articles that describe secondary metabolites of microorganisms, including antibiotics and mycotoxins; physiologically active compounds from terrestrial and marine plants and animals; biochemical studies, including biosynthesis and microbiological transformations; fermentation and plant tissue culture; the isolation, structure elucidation, and chemical synthesis of novel compounds from nature; and the pharmacology of compounds of natural origin.
When new compounds are reported, manuscripts describing their biological activity are much preferred.
