STUDIES ON ANTIMICROBIAL SUBSTANCE B 44 P (STREPTOVARICIN) PRODUCED BY A STRAIN OF ACTINOMYCETES. II

Structural studies on ebelactone A and B, esterase inhibitors produced by actinomycetes.

In the course of our studies on enzyme inhibitors produced by microorganisms, two potent esterase inhibitors named ebelactone A and B, were isolated from the cultured broth of the strain MG7-G1 which was closely related to Streptomyces aburaviensis1). They were determined to be new members of mycolic acid /3-lactone. As reported in our previous papers2.3), esterastin, an esterase inhibitor prod...

Detection of Antimicrobial Effect of Extracellular Protein Produced by Psychrophilic Actinomycetes Isolated from Manali Ice Point

The present study reveals that the effect of extra cellular protein isolated from Psychrophilic Actinomcetes against clinical pathogens. Totally 13 Actinomycetes were isolated from glacier soil. Among them the genus Streptomycetes and Micromonospora were isolated highly. MM9 medium was used as fermentation medium and the antimicrobial peptide activity was performed by disc diffusion method. Out...

TA-3037A, a new inhibitor of glutathione S-transferase, produced by actinomycetes. II. Structure determination.

TA-3037A, a new inhibitor of glutathione S-transferase, has been isolated from the culture broth of Streptomyces sp. TA-3037. The structure of TA-3037A was defined as (Z)-3-benzylidene-3,4-dihydro-2-oxo-2H-1,4-benzoxazine-5-carboxylic acid by an analysis of spectral properties and chemical studies of TA-3037A and its derivatives.
