Optimization and biological evaluation of imidazopyridine derivatives as a novel scaffold for γ-secretase modulators with oral efficacy against cognitive deficits in Alzheimer’s disease model mice
摘要:
Gamma-secretase modulators (GSMs) selectively lower amyloid-beta 42 (A beta 42) and are therefore potential disease-modifying drugs for Alzheimer's disease (AD). Here, we report the discovery of imidazopyridine derivatives as GSMs with oral activity on not only A beta 42 levels but also cognitive function. Structural optimization of the biphenyl group and pyridine-2-amide moiety of compound 1a greatly improved GSM activity and rat microsomal stability, respectively. 5-{8-[(3,4'-Difluoro[1,1'-biphenyl]-4-yl)methoxy]-2-methylimidazo[1,2-a]pyridin3-yl}-N-methylpyridine-2-carboxamide (1o) showed high in vitro potency and brain exposure, induced a robust reduction in brain A beta 42 levels, and exhibited undetectable inhibition of cytochrome p450 enzymes. Moreover, compound 1o showed excellent efficacy against cognitive deficits in AD model mice. These findings suggest that compound 1o is a promising candidate for AD therapeutics.
