Teicoplanin, a new antibiotic from Actinoplanes teichomyceticus nov. sp.
Teicoplanin, a new glycopeptide antibiotic belonging to the same family as vancomycin, inhibits cell wall synthesis in Bacillus subtilis; the inhibition is accompanied by an intracellular accumulation of UDP-N-acetyl-muramyl-pentapeptide. A cell-free system from Bacillus stearothermophilus, capable of synthesizing peptidoglycan, is 50% inhibited by teicoplanin at 40 micrograms/ml and 100% inhib...
متن کاملTeicoplanin, antibiotics from Actinoplanes teichomyceticus nov. sp. V. Aromatic constituents.
Oxidative and hydrolytic degradation reactions were carried out on teicoplanin in order to characterize the aromatic portion of the molecule and relate it to the other members of the class of glycopeptide antibiotics. Seven aromatic rings, obtained as triphenyl ether, diphenyl ether, and diphenyl moieties after oxidation nd hydrolysis of teicoplanin, were identified. They are present in teicopl...

deposited at Japan Collection of Microorganisms and the Institute for Fermentation, Osaka under accession number 10268T and 16408T, respectively. Detailed taxonomic study of the strain K95-55611 will be reported elsewhere3). A stock culture of the producing organism was inoculated into two 500-ml Erlenmeyer flasks containing 100ml of culturing medium. The flasks were incubated at 27°C for 72 ho...
متن کاملNew polyene antifungal antibiotic produced by a species of Actinoplanes.
A new species of Actinoplanes, which has been deposited with the designation NRRL 5325 at the Northern Utilization Research and Development Division of the U. S. Department of Agriculture, produces a polyene antifungal complex designated as Sch 16656. The complex, consisting of one major and three minor components, is isolated from the fermentation broth by a solvent extraction procedure and pu...
متن کاملTeicoplanin, antibiotics from Actinoplanes teichomyceticus nov. sp. VII. Preparation and NMR characteristics of the aglycone of teicoplanin.
Several hydrolytic reactions that transform teicoplanin or its pseudo-aglycones into the aglycone with good yields are described. The most interesting approach is hydrolytic removal of the sugars in benzyl alcohol with the formation of the aglycone benzyl ester which is then submitted to hydrogenolysis. A detailed description of the 1H and 13C NMR spectra of the teicoplanin aglycone hydrochlori...
