The use of quail meat and eggs has made this animal important in recent years, with its low cost and high yields. Glutathione S-transferases (GST, E.C.18.104.22.168) are an important enzyme family, which play a critical role in detoxification system. In our study, GST was purified from quail liver tissue with 47.88-fold purification and 12.33% recovery by glutathione agarose affinity chromatography. The purity of enzyme was checked by SDS-PAGE method and showed a single band. In addition, inhibition effects of (3aR,4S,7R,7aS)-2-(4-((E)-3-(aryl)acryloyl)phenyl)-3a,4,7,7a-tetrahydro-1H-4,7methanoisoindole-1,3(2H)-dion derivatives (1a-g) were investigated on the enzyme activity. The inhibition parameters (IC50 and K-i values) were calculated for these compounds. IC50 values of these derivatives (1a-e) were found as 23.00, 15.75, 115.50, 10.00, and 28.75M, respectively. K-i values of these derivatives (1a-e) were calculated in the range of 3.04 +/- 0.50 to 131.50 +/- 32.50M. However, for f and g compounds, the inhibition effects on the enzyme were not found.
