The design and the synthesis of several chemical subclasses of imidazole containing gamma-secretase modulators (GSMs) is described. Conformational restriction of pyridone 4 into bicyclic pyridone isosteres has led to compounds with high in vitro and in vivo potency. This has resulted, in the identification of benzimidazole 44a as a GSM with low nanomolar potency in vitro. In mouse, rat, and dog, this compound displayed the typical gamma-secretase modulatory profile by lowering A beta 42 and A beta 40 levels combined with an especially pronounced increase in A beta 38 and A beta 37 levels while leaving the total levels of amyloid peptides unchanged.
