چکیده
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.

متن کاملDetermination of Glutathione S-Transferase e2 Region (GSTe2) in DDT Susceptible and Resistant Anopheles stephensi Populations: Significance and Application of Nucleotide and Amino Acid Comparison
Glutathione S-transferases (GSTs) are a major family of detoxification enzymes which possess a wide range of substrate specificities. Interest in insect GSTs has primarily focused on their role in insecticide resistance. In this study, following World Health Organization (WHO) routine susceptibility test, DNA was extracted from specimens of Anopheles stephensi collected from the Kazeroon distri...
متن کاملProduction and Evaluation of Polyclonal Rabbit Anti-Human p53 Antibody Using Bacterially Expressed Glutathione S-transferase-p53 fusion protein
p53 is a key tumor suppressor gene that is targeted for inactivation during human tumorigenesis. In this study, we produced and characterized polyclonal antihuman p53 antibody. The cDNA encoding the completehuman p53 protein was cloned into pGEX-4T-1 and expressed in Escherichia coli as a fusion protein with Schistosoma japonicum glutathione S-transferase (GST). The rabbits were immunized...
متن کاملBenastatins C and D, new inhibitors of glutathione S-transferase, produced by Streptomyces sp. MI384-DF12. Production, isolation, structure determination and biological activities.
Benastatin C, a new member of the benastatins, has been isolated from the culture broth of Streptomyces sp. MI384-DF12. The structure of benastatin C was elucidated as 2-decarboxy-benastatin A by NMR studies. Benastatin D, 2-decarboxybenastatin B, was derived from benastatin B. Benastatins C and D showed inhibitory activities against human pi class glutathione S-transferase (GST pi) and excelle...
