چکیده
New anthracycline antibiotics, designated as obelmycins A, D, E, F and G, were isolated from the culture broth of a variant strain of beta-rhodomycin-producing Streptomyces violaceus A262, identified as beta-isorhodomycinone glycosides and gamma-isorhodomycinone glycosides and assayed for their in vitro cytotoxicities against murine leukemic L1210 cell culture and the antimicrobial activities in comparison with some known anthracyclines.

New anthracycline metabolites produced by the aklavinone 11-hydroxylase gene in Streptomyces galilaeus ATCC 31133.
Transformation of Streptomyces galilaeus ATCC 31133 with the aklavinone 11-hydroxylase gene (dnrF) resulted in the production of many red pigments. The new metabolites were purified and their structures were determined as 11-hydroxylated aclacinomycin A, B and T by spectral analysis. This result indicated that the dnrF was stably expressed in the strain S. galilaeus ATCC 31133 to give rise to h...
متن کاملAntioxidant and cytotoxic activities of metabolites produced by a new marine Streptomyces sp. isolated from the sea cucumber Holothuria leucospilota
Marine microorganisms are important sources for novel natural products. Hence, the aim of this study was to introduce marine microorganisms with the capability of producing antioxidant and cytotoxic metabolites. For this purpose, ten live sea cucumbers (Holothuria leucospilota) were collected from Larak Island, Persian Gulf. Then, their intestine contents were serially diluted and treated by he...
متن کاملHimalomycin A and B: isolation and structure elucidation of new fridamycin type antibiotics from a marine Streptomyces isolate.
In our screening of marine Streptomycetes for bioactive compounds, in addition to the known metabolites rabelomycin (1), fridamycin D (2b), N-benzylacetamide and N-(2'-phenylethyl)acetamide, two new anthracycline antibiotics designated as himalomycin A (2c) and B (2d) were isolated from the culture broth of the marine Streptomyces sp. isolate B6921. The structure of the new antibiotics was dete...
متن کاملArugomycin, a new anthracycline antibiotic. I. Taxonomy, fermentation, isolation and physico-chemical properties.
Arugomycin (AGM) is a new anthracycline antibiotic produced by strain No. 1098-AV2 which was identified as Streptomyces violaceochromogenes. AGM was isolated by solvent extraction, silicic acid chromatography and Sephadex LH-20 column chromatography. Acid treatment of AGM gave the chromophore, named arugorol, which was identified as 4'-epi-nogalarol, and sugar moieties. AGM inhibited the growth...
متن کاملEvaluation of bioactive compounds produced by Nocardia levis MK-VL_113 & Streptomyces tendae TK-VL_333 for cytotoxic activity
Natural products are the logical starting point for discovering new drugs as evidenced by the discovery of penicillin1. More than 60 per cent of approved antitumour drugs are derived from natural compounds2,3. Drugs with anticancer properties including anthracycline, bleomycin, actinomycin and mitomycin have been isolated from actinobacteria4,5. We have earlier reported isolation and characteri...
