title: SF-1961, a new antibiotic related to bleomycin.
abstract: A new type of bleomycin group antibiotic, SF-1961 was isolated from the fermentation broth of Streptomyces species. SF-1961 possessed beta-amino-beta-(4-amino-6-carboxypyrimidin-2-yl)-propionic acid instead of its 5-methyl derivative which was a common component of bleomycins and phleomycins.
