Secondary metabolites from marine actinomycete Streptomyces sp. G330

Abstract

Eight compounds, 2,4-dichloro phenyl 2,4-dichloro benzoate (1), cyclo-(Pro-Trp) (2), cyclo-(Pro-Leu) (3), cyclo (Trp-Ser) (4), cyclo (Trp-Ala) (5), indol 3-acetic acid (6), 3-hydroxyacetylindol (7) and indol-3-carboxylic acid (8) were isolated and characterized from the culture broth of the marine actinomycete Streptomyces sp. G330 strain. Their structures were determined by spectroscopic analysis including MS, 1D and 2D NMR, as well as by comparison with reported data in literature.
