Title: Butirosin
CAS Registry Number: 12772-35-9
Synonyms: Ambutyrosin
Molecular Formula: C21H41N5O12
Molecular Weight: 555.58
Percent Composition: C 45.40%, H 7.44%, N 12.61%, O 34.56%
Literature References: Aminoglycosidic antibiotic complex obtained from fermentation filtrates of mucoid strains of Bacillus circulans (NRRL B-3312 and B-3313). Consists of two components, butirosin A (80-85%) and butirosin B (15-20%), isomers which differ only in the configuration at one carbon atom in the pentose moiety. Prepn: P. W. K.
