ANTIBIOTIC YC 73 OF PSEUDOMONAS ORIGIN. II

STRUCTURE AND SYNTHESIS OF THIOFORMIN AND ITS CUPRIC COMPLEX (YC 73)

Abstract

The structure of thioformin, a new acidic antibiotic substance obtained by removing cupric ion from antibiotic YC 73, was shown to be N-methyl-N-thioformylhydroxylamine by degradative and synthetic studies. Numerous metal complexes of thioformin, including the cupric (antibiotic YC 73 itself) and ferric complexes, were also synthesized and characterized.
