Chemical constituents of Caesalpinia decapetala (Roth) Alston.
The current study targets the chemical constituents of Caesalpinia decapetala (Roth) Alston and investigates the bioactivities of the isolated compounds. Fourteen known compounds were isolated using column chromatography, and structural identification was performed by physical and spectral analyses. The biological activities of the compounds were also evaluated by 3-(4,5-dimethythiazol-2-yl)-2,...
متن کاملNew cassane-type diterpenoids from Caesalpinia bonduc.
Six new cassane diterpenoids, named caesalls H-M (1-6), were isolated from the seed kernels of Caesalpinia bonduc. Their structures were elucidated on the basis of spectroscopic analysis, mainly NMR and MS. The absolute configurations of compounds 1 and 3 were determined by a single-crystal X-ray study using a mirror CuKα radiation and circular dichroism (CD) spectra, respectively. None of the ...
متن کاملReduction of MTT by glutathione S-transferase.
The reduction of the tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) to a blue formazan product is widely used for assaying cell survival and proliferation. The reduction reaction is catalyzed by dehydrogenases localized in the mitochondria of viable cells. As part of an analysis of the ability of glutathione S-transferase (GST) enzymes to protect cells from...

doxorubicin8). Inhibitors of this enzyme, ethacrynic acid and piriprost are already known and their potential therapeutic utility in combination with alkylating agents has been suggested by Tew and his colleagues9). Our group has been screening for novel inhibitors of glutathione S-transferase from microbial origin and we recently isolated tryptophandehydrobutyrine diketopiperazine10) (TDD) and...
متن کاملA ligand function of glutathione S-transferase.
Glutathione S-transferases (GSTs) are ubiquitous enzymes and abundant in plants. They are intimately involved in plant metabolism and stress defense related to reactive oxygen species. Our project assigned particular reactions including novel ones to certain GST-isoforms. Transformed E. coli was used to express recombinant GST-isoforms from maize. An N-terminal His tag allowed their purificatio...
