title: Actinopyrones A, B and C, new physiologically active substances. I. Producing organism, fermentation, isolation and biological properties.
abstract: A strain of Streptomyces was found to produce new physiologically active substances. The active compounds were purified and separated into three substances named actinopyrones A, B and C. Actinopyrones exhibited coronary vasodilating activities in anesthetized dogs and weakly antimicrobial activities against some Gram-positive bacteria and dermatophytes.
