Discovery of potent and bioavailable GSK-3β inhibitors
摘要:
Here we report on the discovery of a series of maleimides which have high potency and good selectivity for GSK-3 beta. The incorporation of polar groups afforded compounds with good bioavailability. The most potent compound 34 has an IC(50) of 0.6 nM for GSK-3 beta, over 100-fold selectivity against a panel of other kinases, and shows efficacy in rat osteoporosis models. The X-ray structure of GSK-3 beta protein with 34 bound revealed the binding mode of the template and provided insights for future optimization opportunities. (C) 2010 Elsevier Ltd.
