Evaluation of a Series of β‑Secretase 1 Inhibitors Containing Novel Heteroaryl-Fused-Piperazine Amidine Warheads

Despite several years of research, only a handful of β-secretase (BACE) 1 inhibitors have entered clinical trials as potential therapeutics against Alzheimer’s disease. The intrinsic basic nature of low molecular weight, amidine-containing BACE 1 inhibitors makes them far from optimal as central ner...

description Despite several years of research, only a handful of β-secretase (BACE) 1 inhibitors have entered clinical trials as potential therapeutics against Alzheimer’s disease. The intrinsic basic nature of low molecular weight, amidine-containing BACE 1 inhibitors makes them far from optimal as central nervous system drugs. Herein we present a set of novel heteroaryl-fused piperazine amidine inhibitors designed to lower the basicity of the key, enzyme binding, amidine functionality. This study resulted in the identification of highly potent (IC50 ≤ 10 nM), permeable lead compounds with a reduced propensity to suffer from P-glycoprotein-mediated efflux.
