Abstract
A Tripterygium wilfordii endophyte, Streptomyces sp. CB04723, was shown to produce an unusually highly reduced cytotoxic cinnamoyl lipid, tripmycin A (1). Structure–activity relationship studies revealed that both the cinnamyl moiety and the saturated fatty acid side chain are indispensable to the over 400-fold cytotoxicity improvement of 1 against the triple-negative breast cancer cell line MDA-MB-231 compared to 5-(2-methylphenyl)-4-pentenoic acid (2). Bioinformatical analysis, gene inactivation, and overexpression revealed that Hxs15 most likely acted as an enoyl reductase and was involved with the side chain reduction of 1, which provides a new insight into the biosynthesis of cinnamoyl lipids.
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.
