Abstract

1,212,741. Antibiotic B-2847. TAKEDA YAKUHI KOGYO K.K. 23 Feb., 1968 [25 Feb., 1967; 9 Sept., 1967], No. 8879/68. Heading C2A. The antibacterial antibiotic B-2847 and its components B-2847Y and B-2847R are produced by culturing Streptomyces tolypophorus ATCC 21177 or a B-2847-producing mutant thereof, in a medium containing assimilable sources of carbon and nitrogen and inorganic salts under aerobic conditions. The antibiotic is recovered from the clarified broth or separated mycelium. The clarified broth is washed with n-hexane, adjusted to pH 2 to 8 and extracted with a water-immiscible solvent such as ethyl acetate. The extract is washed with aqueous phosphate buffer of pH 8À0 and then with water. After concentration, the crude antibiotic, as B-2847Y, is precipitated by the addition of n-hexane. Further purification is by chromatography on silica gel using benzene-ethyl acetate (1:1), adsorption on activated C and recrystallization from n-hexane-ethyl acetate. The separated mycelium may be extracted with acetone-water (3: 1), filtered, concentrated, adjusted to pH 3À5, extracted with ethyl acetate and crude antibiotic precipitated by the addition of n-hexane. B-2847R is the reduced form of B2847Y and is recovered in the pure form when any of the above isolation and purification steps are carried out in the presence of L-ascorbic acid. The antibiotic components are easily soluble in CH 3 OH, C 2 H 5 OH, n-butanol, acetone, chloroform, ethyl acetate or benzene; insoluble in water, petroleum ether or n-hexane. Pharmaceutical preparations for topical use, e.g. ointments, comprise the antibiotic B-2847Y or B-2847R. Solutions of the antibiotics may be used as a general disinfectant.
