Function
[LGUL_HUMAN] Catalyzes the conversion of hemimercaptal, formed from methylglyoxal and glutathione, to S-lactoylglutathione. Involved in the regulation of TNF-induced transcriptional activity of NF-kappa-B.[1]
Publication Abstract from PubMed
We conducted a high throughput screening for glyoxalase I (GLO1) inhibitors and identified 4,6-diphenyl-N-hydroxypyridone as a lead compound. Using a binding model of the lead and public X-ray coordinates of GLO1 enzymes complexed with glutathione analogues, we designed 4-(7-azaindole)-substituted 6-phenyl-N-hydroxypyridones. 7-Azaindole's 7-nitrogen was expected to interact with a water network, resulting in an interaction with the protein. We validated this inhibitor design by comparing its structure-activity relationship (SAR) with that of corresponding indole derivatives, by analyzing the binding mode with X-ray crystallography and by evaluating its thermodynamic binding parameters.
