چکیده

TA-3037A, a new inhibitor of glutathione S-transferase was discovered in the fermentation broth of Streptomyces sp. TA-3037. It was purified by chromatography followed by solvent extraction and then isolated as yellow needles. TA-3037A has the molecular formula of C16H11NO4. It was competitive with the substrate, and the inhibition constant (Ki) was 4.9 microM.
