Abstract:

The secondary metabolites of marine actinomycete Streptomyces sporoverrucosus 33510 were studied in order to obtain bioactive compounds. The compounds were separated and purified by column chromatography, semi-preparative liquid chromatography and other chromatographic methods. Ten compounds were identified as cyclo(D-Pro-D-Leu) (1), bisphenol A (2), methylp-hydroxyphenylacetate (3), N-phenethylacetamide (4), 3-indole-methylethanoate (5), dibutyl phthalate (6), cyclo(D-Pro-L-Leu) (7), cyclo(D-Pro-L-Ile) (8), cyclo(L-Pro-L-Phe) (9), and cyclo(L-Leu-L-Val) (10). Eight compounds were isolated from Streptomyces sporoverrucosus for the first time. Compound 2 showed inhibitory activity against Cryphonectria parasitica.

Key words: Streptomyces sporoverrucosus 33510, secondary metabolites, antibacterial activity
