  Structure activity relationship studies of tricyclic bispyran sulfone γ-secretase inhibitors

  摘要：

  An investigation is detailed of the structure activity relationships (SAR) of two sulfone side chains of compound (-)-1a (SCH 900229), a potent, PS1-selective gamma-secretase inhibitor and clinical candidate for the treatment of Alzheimer's disease. Specifically, 4-CF3 and 4-Br substituted arylsulfone analogs, (-)-1b and (-)-1c, are equipotent to compound (-)-1a. On the right hand side chain, linker size and terminal substituents of the pendant sulfone group are also investigated. (c) 2012 Elsevier Ltd. All rights reserved.

  of γ-secretase inhibitors led to the identification of compound (−)-16 (SCH 900229), which is a potent and PS1 selective inhibitor of γ-secretase (Aβ40 IC50 = 1.3 nM). Compound (−)-16 demonstrated excellent lowering of Aβ after oral administration in preclinical animal models and was advanced to human clinical trials for further development as a therapeutic agent for the treatment of Alzheimer’s disease
