Design of Potent and Highly Selective Inhibitors for Human β-Secretase 2 (Memapsin 1), a Target for Type 2 Diabetes.

Abstract

Design, synthesis and evaluation of very potent and selective β-Secretase 2 (memapsin 1, BACE 2) inhibitors are described. The inhibitors were designed specifically to interact with the S2'-site of β-secretase 2 to provide >170,000-fold selectivity over β-secretase (BACE 1) and >15,000-fold selectivity over cathepsin D. BACE 2 is implicated in Type 2 diabetes. The studies serve as an important guide to selective BACE 2 inhibitors.
