Abstract/OtherAbstract:
Two peptides, tumescenamides A and B, were isolated from the fermentation broth of a marine bacterium, Streptomyces tumescens YM23-260. The structure of tumescenamide A was determined to be a cyclic depsipeptide consisting of α-amino-2-butenoic acid, tyrosine, valine, leucine and threonine, substituted with a 2,4-dimethylheptanoyl residue at the α-NH(2) position. Tumescenamide B possesses a 2,4,6-trimethylnonanoyl residue in place of the 2,4-dimethylheptanoyl substituent in tumescenamide A. Tumescenamide A induced reporter gene expression under the control of the insulin-degrading enzyme promoter.
