Phaeochromycins F–H, three new polyketide metabolites from <i>Streptomyces</i> sp. DSS-18

Abstract

Three new polyketides, phaeochromycins F (1), G (2), H (3), were obtained from the culture broth of marine actinomycete strain Streptomyces sp. DSS-18. Their structures were established on the basis of detailed spectroscopic analyses, including 1D-, 2D-NMR and HR-ESI MS techniques.
