    摘要: A substance having antibiotic activity, designated as cytophagin, which is stable in the form of colorless powder and which has an elemental analysis of H: 6.94%, C: 47.22% and N: 13.21%, a molecular weight of 1,000 to 1500. This substance is believed to be composed of 11 amino acids and exhibits a strong activity against Gram-positive bacteria. Cytophagin is produced by fermentation using a microorganism belonging to the genus Cytophaga and capable of producing cytophagin. A preferred strain is Cytophaga BMF 694-N3 (FERM P-4846;NRRL B-12109). Cytophagin is of potential interest as medicament or veterinary agent because of its antibiotic activity.

    摘要: New anthracycline glycosides designated MA 144-G1, -G2, -L, -S1, -N1, -U1 and -Y which inhibit the growth of gram-positive bacteria and mammalian tumors are produced by fermentation of certain species of Streptomyces and by the chemical or enzymatic conversion of certain anthracycline glycosides. New microbiological and chemical processes are also provided for preparation of the anthracycline glycosides MA 144-S2 and -U2 which have been found to be identical with the previously reported anthracyclines, marcellomycin and musettamycin.
