摘要:
[GRAPHICS]A new class of competitive inhibitors of homodimeric human glyoxalase 1 has been created by cross-linking two molecules of the transition-state analogue S-(N-4-chlorophenyl-N-hydroxycarbamoyl)glutathione (CHG) through their gamma-glutamyl-NH2 groups with poly-beta-alanyl tethers of differing length: [CHG(beta-ala)(n)](2) suberate diamide (n = 1-7). The strongest inhibitors of this antitumor target enzyme likely bind simultaneously to the active site on each subunit to give K-i values as small as 0.96 nM (n = 6).
