Polyketides from a soil -derived Streptomyces sp. CSDX076 and their antimicrobial activities
A new naturally occurring polyketide, pseurotin A3-10,11-acetonide (1), along with two known analogs, pseurotin A (2) and pseurotin A3 (3), was isolated from the culture broth of Streptomyces sp. CSDX076. The structures of these compounds were determined by extensive 1D and 2D nuclear magnetic resonance (NMR), ultravio...
