摘要:
SAR of a novel series of pyridine-derived gamma-secretase modulators is described. Compound 5 was found to be a potent modulator in vitro, which on further profiling, was found to decrease A beta 42 and A beta 40, and maintain (or increase) the levels of total A beta. Furthermore, representative compounds 1 and 5 demonstrated in vivo efficacy to lower A beta 42 in the brain without altering Notch processing in the peripheral. (C) 2011 Elsevier Ltd.
