G2201-C, A NEW CYCLOPENTENEDIONE ANTIBIOTIC, ISOLATED FROM THE FERMENTATION BROTH OF STREPTOMYCES CATTLEYA

Abstract

Streptomyces cattleya produced a new cyclopentenedione antibiotic, G2201-C [C₆H₆O₄ (I)], which is moderately active in vitro against Gram-positive bacteria, weakly active against Gram-negative bacteria, and inactive against fungi. G2201-C is toxic to mice.
