Abstact

We herein report the first covalent G-site-binding inhibitor for GST, GS-ESF (1), which irreversibly inhibited the GSTP1-1 function. LC-MS/MS and X-ray structure analyses of the covalently linked GST-inhibitor complex suggested that 1 reacted with Tyr108 of GSTP1-1. The mechanism of covalent bond formation was discussed based on MD simulation results.
