Abstract:

The strain SCSIO 1635 was isolated from marine sediment of the South China Sea, and identified as a member of Streptomyces according to the 16S rDNA sequence. Four compounds were isolated from Streptomyces sp. SCSIO 1635. The compounds were found to be structurally-related to antimycins by detailed analyses of MS and NMR spectroscopic data, and were identified as antimycin A1a and A1b (1), deisovalerylblastmycin (2), kitamycin A (3), and antimycin A9 (4), respectively.

Key words: marine sediments of South China Sea, marine actinomycetes, marine microbial natural products, Streptomyces, antimycins
