摘要:

我们从南海海底沉积环境分离了一株放线菌SCSIO 1635,经16S rDNA的序列分析将该株菌鉴定为链霉菌属。我们从该菌的发酵液中分离得到了4个化合物,经质谱和核磁共振波谱解析,确定为抗霉素类化合物:异构体antimycin A1a 和 A1b(1)、deisovalerylblastmycin(2)、kitamycin A(3)和antimycin A9(4)。

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
