Abstract
NEW MATERIAL:An antibiotic DC-11-B. A melting point: 181W184°C. Elemental analysis: C 61.0%, H 7.5%, N 2.2%. Specific rotatory power: [α]D21=-8.28 (C=1.0 acetone). Solubility: easily soluble in methanol, ethanol, etc., slightly soluble in methanol, ethanol, etc., slightly soluble in benzene, water, and insoluble in ethyl ether, petroleum ether, etc.
USE: An antitumor agent or antibacterial agent. Being administered to the vein or abdominal cavity as an injection.
PROCESS: For example, Micromonospora chalcea KY11091 (FERMP4458) is subjected to liquid cultivation under aerobical conditions, the desired substance is adsorbed from the filtrate on a nonionic porous resin, etc. and desorbed by ethanol, etc. The resulting substance is purified and separated by adsorption and desorption by active carbon, silica gel chromatography in the presence of α-tocopherol, to give DC-11-B.
