Structure-based optimization of oxadiazole-based GSK-3 inhibitors
摘要:
Inhibition of glycogen synthase kinase-3 (GSK-3) induces neuroprotective effects, e.g. decreases beta-amyloid production and reduces tau hyperphosphorylation, which are both associated with Alzheimer's disease (AD). The two isoforms of GSK-3 in mammalians are GSK-3 alpha and beta, which share 98% homology in their catalytic domains. We investigated GSK-3 inhibitors based on 2 different scaffolds in order to elucidate the demands of the ATP-binding pocket [1]. Particularly, the oxadiazole scaffold provided potent and selective GSK-3 inhibitors. For example, the most potent inhibitor of the present series, the acetamide 26d, is characterized by an IC50 of 2 nM for GSK-3 alpha and 17 nM for GSK-3 beta. In addition, the benzodioxane 8g showed up to 27-fold selectivity for GSK-3 alpha over GSK-3 beta, with an IC50 of 35 nM for GSK-3 alpha. Two GSK-3 inhibitors were further profiled for efficacy and toxicity in the wild-type (wt) zebrafish embryo assay to evaluate simultaneously permeability and safety. (C) 2012 Elsevier Masson SAS.
