Rational design of novel, potent piperazinone and imidazolidinone BACE1 inhibitors

Bioorg Med Chem Lett. 2008 Jun 1;18(11):3236-41. doi: 10.1016/j.bmcl.2008.04.050. Epub 2008 Apr 25.

Abstract

Guided by structure-based design, we synthesized two novel series of potent inhibitors of BACE1 and generated extensive SAR around both the prime and non-prime side binding pockets. The key feature of both series is a cyclic amine motif specifically crafted to achieve interactions with both the flap and with the S2' pocket.
