Abstract
NEW MATERIAL:Antibiotics A11725 Ia and IIa. Ia: color, white; molecular formula, C37H61NO11; molecular weight, 695; melting point, 174W176°C; specific rotation [α]D=+2.7° (c=1.0, methanol); positive to KMnO4 decoloration reaction, negative to ninhydrin reaction, etc.; basic; soluble in acidic water, methanol, benzene, etc., slightly soluble in basic water, insoluble in hexane. IIa: color, white; molecular formula, C37H61NO12; molecular weight, 711; melting point, 148W150°C; specific rotation, [α]D=+18.7° (c=1.0, methanol); basic; solubility, same to Ia.
USE: Antibacterial agent effective to respiratory diseases caused by gram-positive bacteria, e.g. staphylococci, and useful as a feed additive or remedy for animal diseases.
PROCESS: Micromonospora sp. A-11725 strain (FERM-P No.4485, 4488) is cultured to obtain novel macrolide antibiotics A11725 I and II. The epoxy groups of the above antibiotics are converted to double bonds by treating with chromous chloride in an organic solvent.
