title: A novel antibiotic produced by Streptomyces noursei Da07210.
abstract: A novel antibiotic 210-A, named as (6S,8aS,9S,11S,12aR)-6-hydroxy-9,10-dimethyldecahydrobenzo[d]azecine-2,4,12(3H)-trione, was isolated from the fermentation broth of Streptomyces noursei Da07210, its structure was unambiguously established by spectral analyses and chemical comparison with related cycloheximide. Experiments demonstrated that 210-A bore strong activity against Fusarium oxysporum f. sp. cubense race four (Foc race four), which also showed antitumor activity against SMMC-7721 human hepatocarcinoma cells and S180 murine sarcoma, and the IC(50) values were 0.77 and 0.74 microg/ml, respectively.
