Albusamides A-G: Hydroxylated Fatty Amine Derivatives from the Deep-Sea-Derived Actinomycete Streptomyces albus 228DD-066 and Their Cytotoxic Activity.
A series of new hydroxylated fatty amine derivatives, albusamides A-G (1-7), along with four known compounds (8-11), which are reported for the first time from a natural source, were isolated from the culture broth of Streptomyces albus 228DD-066 derived from a deep-sea sediment sample gathered off the coast of Dokdo Island, Republic of Korea. Their structures were elucidated through the comprehensive analysis of 1D and 2D NMR spectra and HRESIMS, and absolute configurations were determined using the modified Mosher's method. Biological evaluations against solid and blood cancer cell lines revealed that these new metabolites have moderate to strong cytotoxic activity. Compound 3 exhibited high cytotoxic activity with GI50 values ranging from 0.4 to 0.6 μM against solid cancer cell lines and exhibited the strongest cytotoxicity (GI50 value = 0.2 μM) against the WSU-DLCL2 blood cancer cell line.
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.
