BACE-1 Inhibitors Part 3: Identification of Hydroxy Ethylamines (HEAs) With Nanomolar Potency in Cells

Bioorg Med Chem Lett. 2008 Feb 1;18(3):1022-6. doi: 10.1016/j.bmcl.2007.12.020. Epub 2007 Dec 15.

Abstract

This article is focusing on further optimization of previously described hydroxy ethylamine (HEA) BACE-1 inhibitors obtained from a focused library with the support of X-ray crystallography. Optimization of the non-prime side of our inhibitors and introduction of a 6-membered sultam substituent binding to Asn-294 as well as a fluorine in the C-2 position led to derivatives with nanomolar potency in cell-based assays.
