Deisovalerylblastmycin produced by Streptomyces SP.
A new antifungal antibiotic was isolated from the fermentation broth of Streptomyces sp. 5140-A1. Degradation studies of the crystalline antibiotic, m.p. 186 approximately 188 degrees C, C21H28O8N2, suggested Piricularia oryzae and less toxicity against killfish than antimycin A--blastmycin antibiotics.
متن کاملEpostatin, new inhibitor of dipeptidyl peptidase II, produced by streptomyces sp. MJ995-OF5 II. Structure elucidation.
During the course of screening fermentation broths for new inhibitors of dipeptidyl peptidase II (EC 3.4.14.2), we discovered epostatin (C23H33N3O5) from Streptomyces sp. MJ995-OF5. The taxonomy of producing strain, fermentation, isolation, physico-chemical properties and biological properties have been described in the preceding paper1). Herein we report on the structure determination of epost...
متن کاملPhthoxazolin, a specific inhibitor of cellulose biosynthesis, produced by a strain of Streptomyces sp.
involved in humanand animal cells, it provides a promising target site for safe and non-selective herbicides of a novel class. Inhibitors of cellulose biosynthesis of microbial origin have not been documented, although a recent article3) from our laboratories suggested phthoramycin as a nonspecific inhibitor of polysaccharide biogenesis, probably acting on cellulose synthesis as well. We descri...
متن کاملAnti-influenza Virus Effects of a Proteolytic Inhibitor, Produced by Streptomyces Sp
Abstract Despite the success in development of antiviral drugs, a need continues to exist for effective therapies for viral infections. Proteinase inhibitors of microbial origin could be used successfully as antiviral agents. The virus-inhibitory activity of a fermentation product, produced by Streptomyces sp. 225b (SS 225) was studied with respect to the specificity and selectivity of inhibiti...
متن کاملA new inhibitor of melanogenesis, albocycline K3, produced by Streptomyces sp. OH-3984.
The fermentation and isolation of 1 were carried out in the same way as reported previously1}. Astock culture of the producing organism was inoculated into a test tube (i.d. 2x20cm) containing 10ml of seed medium consisting of2% glucose, 0.5% peptone, 0.3% dry yeast, 0.5% meat extract, 0.5% NaCl and 0.3% CaCO3 (pH 7.0 before sterilization). The tube was incubated at 27°C for 72 hours on a recip...
