| Abstract: | From ezomycin complex produced by a strain of Streptomyces were isolated four components named ezomycins A1 (C26H40N8O16S), A2 (C19H28N6O13), B1 (C26H39N7O17S) and B2 (C19H27N5O14) which are new pyrimidine nucleosides. Ezomycins A1 and B1 containing l-cystathionine were found to be responsible for specific antimicrobial activity of the complex against Sclerotinia and Botrytis species. |
