PubMed Abstract:
Human glyoxalase I (hGLO I) is an enzyme for detoxification of methylglyoxal (MG) and has been considered an attractive target for the development of new anticancer drugs. In our previous report, the GLO I inhibitor TLSC702 induced apoptosis in tumor cells. Here, we determined the crystal structures of hGLO I and its complex with TLSC702. In the complex, the carboxyl O atom of TLSC702 is coordinated to Zn ²⁺ , and TLSC702 mainly shows van der Waals interaction with hydrophobic residues. In the inhibitor-unbound structure, glycerol, which has similar functional groups to MG, was bound to Zn ²⁺ , indicating that GLO I can easily bind to MG. This study provides a structural basis to develop better anticancer drugs.
