Description

It is produced by the strain of Streptomyces violaceus A262. It has anti-gram positive, negative bacteria and candida albicans activity, and has anti-leukemic L1210 activity, which is stronger than Aclacinomycin.

Reference Reading

1. Anthracycline metabolites from Streptomyces violaceus A262. II. New anthracycline epelmycins produced by a blocked mutant strain SU2-730
O Johdo, Y Watanabe, T Ishikura, A Yoshimoto, H Naganawa, T Sawa, T Takeuchi J Antibiot (Tokyo). 1991 Oct;44(10):1121-9. doi: 10.7164/antibiotics.44.1121.
New anthracycline antibiotics, identified as epsilon-rhodomycinone glycosides, were isolated from the culture broth of a blocked mutant of beta-rhodomycin-producing Streptomyces violaceus A262. They were designated as epelmycins A, B, C, D and E, and assayed for their in vitro cytotoxicities against murine leukemic L1210 cell culture and the antimicrobial activities in comparison with known anthracycline antibiotics.
2. Production of a new hybrid anthracycline 4-O-methylepelmycin by heterologous expression of dnrK in epelmycin-producing Streptomyces violaceus
Y Miyamoto, S Ohta, O Johdo, Y Nagamatsu, A Yoshimoto J Antibiot (Tokyo). 2000 Aug;53(8):828-36. doi: 10.7164/antibiotics.53.828.
A new hybrid anthracycline antibiotic was produced by heterologous expression of dnrK encoding carminomycin 4-O-metyltransferase in an epelmycin-producing Streptomyces violaceus. pMK100 was constructed by insertion of Steptomyces peucetius dnrK gene in Steptomyces-expression vector pIJ6021 and introduced to the epelmycin producer. The transformant produced a hybrid anthracycline antibiotic together with host epelmycins when cultured in antibiotic production medium in the presence of thiostrepton. The hybrid anthracycline was determined to be 7-O-L-rhodosaminyl-4-O-methyl-epsilon-rhodomycinone (4-O-methylepelmycin D). However, the attempts on production of hybrid 4-O-methylaclarubicin and 4-O-methyl-1-deoxyobelmycin by the transformants of aclarubicin and 1-deoxyobelmycin producers with pMK 100 were unsuccessful.
