Salternamide E from a Saltern-derived Marine Actinomycete Streptomyces sp
− Comprehensive chemical analysis of extracts and fractions of marine actinomycete strains led to the discovery of a new minor secondary metabolite, salternamide E (1), from a saltern-derived halophilic Streptomyces strain. The planar structure of salternamide E (1) was elucidated by a combinational analysis of spectroscopic data including NMR, MS, UV, and IR. The absolute configuration of salt...
متن کاملDiketopiperazine Derivatives from the Marine-Derived Actinomycete Streptomyces sp. FXJ7.328
Five new diketopiperazine derivatives, (3Z,6E)-1-N-methyl-3-benzylidene-6-(2S-methyl-3-hydroxypropylidene)piperazine-2,5-dione (1), (3Z,6E)-1-N-methyl-3-benzylidene-6-(2R-methyl-3-hydroxypropylidene)piperazine-2,5-dione (2), (3Z,6Z)-3- (4-hydroxybenzylidene)-6-isobutylidenepiperazine-2,5-dione (3), (3Z,6Z)-3-((1H-imidazol-5-yl)-methylene)-6-isobutylidenepiperazine-2,5-dione (4), and (3Z,6S)-3-b...
متن کاملSeparacenes A–D, Novel Polyene Polyols from the Marine Actinomycete, Streptomyces sp
Separacenes A-D (1-4), novel polyene polyols, were isolated from Streptomyces sp. collected from the southern area of Jeju Island, Korea. The chemical structures of 1-4 were established by NMR, mass, UV, and IR spectroscopy as well as the modified Mosher's method. Separacenes A-B (1-2), which share an identical planar structure but possess different relative configurations, bear tetraene units ...
متن کاملTwo Antimycin A Analogues from Marine-Derived Actinomycete Streptomyces lusitanus
Two new antimycin A analogues, antimycin B1 and B2 (1-2), were isolated from a spent broth of a marine-derived bacterium, Streptomyces lusitanus. The structures of 1 and 2 were established on the basis of spectroscopic analyses and chemical methods. The isolated compounds were tested for their anti-bacterial potency. Compound 1 was found to be inactive against the bacteria Bacillus subtilis, St...
متن کاملDraft Genome Sequence of the Anti-Algal Marine Actinomycete Streptomyces sp. JS01
Streptomyces sp. JS01 is the producer of an anti-algal compound that shows inhibitory activity against a harmful algal species Phaeocystis globosa and can also produce a red pigment. Its genome sequence will allow for the characterization of the anti-algal compound and the molecular mechanisms underlying its beneficial properties.
