  Identification of small molecules that inhibit GSK-3β through virtual screening

  摘要：

  Glycogen synthase kinase-3 beta (GSK-3 beta) is involved in glycogen metabolism, neuronal cell development, osteoblast differentiation. Small molecule inhibitors of GSK-3 beta have various therapeutic potential for the treatment of diabetes type II, bipolar disorders, stroke and chronic in. ammatory disease.To identify GSK-3 beta inhibitors with novel scaffold from chemical library, we primarily screened out putative inhibitors through computer modeling and subsequently evaluated the inhibitory activity of selected compounds against GSK-3 beta by in vitro Z'-LYTE (TM) assay. A series of compound KRMs strongly inhibited phosphorylation of its substrate with IC50 value of approximately 0.5 mu M. Also, we demonstrated that KRM-189 and KRM-191 competed with ATP for GSK-3 beta, leading to decreased V-max and constant Km with increasing concentrations of ATP as determined from Lineweaver-Berk equation. Moreover, they showed the selectivity for GSK-3 beta over other kinases with IC50 values of 2 to 10 mu M or more Incubation of cells with KRM-191 with highly selective and potent inhibitory activity caused accumulation of beta-catenin, downstream of GSK-3 beta signaling pathway, indicating that small molecule can prevent degradation of beta-catenin via GSK-3 beta inhibition. Our results suggest that modeling in combination with in vitro assays can be used for the identification of selective and potent inhibitors. (C) 2008 Elsevier Ltd. All rights reserved.
