COMPLESTATIN AND CHLOROPEPTIN I, CONDENSED AROMATIC PEPTIDES FROM TWO STRAINS OF STREPTOMYCETES

Abstract The mycelial extract of the fermentation broths from two strains of streptomycetes were found to contain complestatin and a mixture of complestatin and chloropeptin I, respectively. Extraction and detection of these compounds using identical procedures is evidence that complestatin and chloropeptin I are indeed natural products.
