Helioferins; novel antifungal lipopeptides from Mycogone rosea: screening, isolation, structures and biological properties.
Helioferins A and B were detected as novel aminolipopeptides in cultures of Mycogone rosea DSM 8822 in the course of a screening for mediators of helianthate anion transfer from aqueous to toluene phases. Their structures as novel antibiotics and cytotoxic agents were elucidated by mass spectrometry and NMR spectroscopic methods. Antimicrobial activity was estimated against Candida albicans and...
متن کاملFormation of new lipoaminopeptides, acremostatins A, B, and C, by co-cultivation of Acremonium sp. Tbp-5 and Mycogone rosea DSM 12973.
Formation of new lipoaminopeptides, acremostatins A, B, and C, was observed during co-cultivation of Acremonium sp. Tbp-5 and Mycogone rosea DSM 12973. Thus, co-cultivation of microorganisms producing related products could be suggested as a suitable way towards diversification of microbial structures.
متن کاملA new antitumor antibiotic product, demethylchartreusin. Isolation and biological activities.
A new antitumor antibiotic, 3''-demethylchartreusin was isolated from the culture broth of Streptomyces chartreusis, as a minor component of crude chartreusin. It is structurally related to chartreusin, containing same aglycone of chartreusin, but different sugar moieties. 3''-Demethylchartreusin exhibits some potent inhibitory activities against murine tumors.
متن کاملA new anti-MRSA antibiotic complex, WAP-8294A. I. Taxonomy, isolation and biological activities.
WAP-8294A, produced by Lysobacter sp., is a complex consisting of water soluble depsipeptide antibiotics. It was further purified by column chromatographies and HPLC, and 19 components were obtained. WAP-8294A2, a major component, and minor components A1, A4, Ax8, Ax9 and Ax13 were active against gram-positive bacteria, in particular, methicillin-resistant Staphylococcus aureus (MRSA) in vitro....
متن کاملProduction and biological activities of a new antifungal antibiotic, TAN-950 A.
A novel antifungal antibiotic, TAN-950 complex, was isolated from the culture filtrate of Streptomyces platensis A-136 (IFO 14603, FERM BP-1786). The water-soluble amphoteric substances in this complex were purified by chromatography using ion-exchange resins, QAE-Sephadex and adsorptive resins and were designated TAN-950 A and TAN-950 A-E mixture. The molecular formula of TAN-950 A was determi...
