STUDIES ON THE IONOPHOROUS ANTIBIOTICS. XXIV LEUSERAMYCIN, A NEW POLYETHER ANTIBIOTIC PRODUCED BY STREPTOMYCES HYGROSCOPICUS
A new antibiotic leuseramycin has been isolated from the cultured mycelium of the strain of Streptomyces hygroscopicus TM-531. Physicochemical data, in particular those of 1H- and 13C-NMR spectra, revealed that leuseramycin is closely related to dianemycin in its structure, the former having a methy...

Summary: | A new antibiotic leuseramycin has been isolated from the cultured mycelium of the strain of Streptomyces hygroscopicus TM-531. Physicochemical data, in particular those of 1H- and 13C-NMR spectra, revealed that leuseramycin is closely related to dianemycin in its structure, the former having a methyl group in place of the hydroxymethyl group at C-30. It is active against Gram-positive bacteria, some phytopathogenic fungi and some protozoa. |
