Fluorinated piperidine acetic acids as γ-secretase modulators
摘要:
We report herein a novel series of difluoropiperidine acetic acids as modulators of gamma-secretase. Synthesis of 2-aryl-3,3-difluoropiperidine analogs was facilitated by a unique and selective beta-difluorination with Selectfluor (R). Compounds 1f and 2c were selected for in vivo assessment and demonstrated selective lowering of A beta 42 in a genetically engineered mouse model of APP processing. Moreover, in a 7-day safety study, rats treated orally with compound 1f (250 mg/kg per day, AUC(0-24) = 2100 mu M h) did not exhibit Notch-related effects. (C) 2009 Elsevier Ltd. All rights reserved.
