Crystal structure of beta-secretase complexed with an amino-ethylene inhibitor
Overview
A series of novel beta-site amyloid precursor protein cleaving enzyme (BACE-1) inhibitors containing an aminoethylene (AE) tetrahedral intermediate isostere were synthesized and evaluated in comparison to corresponding hydroxyethylene (HE) compounds. Enzymatic inhibitory values were similar for both isosteres, as were structure-activity relationships with respect to stereochemical preference and substituent variation (P2/P3, P1, and P2'); however, the AE compounds were markedly more potent in a cell-based assay for reduction of beta-secretase activity. The incorporation of preferred P2/P3, P1, and P2' substituents into the AE pharmacophore yielded compound 7, which possessed enzymatic and cell assay IC(50)s of 26 nM and 180 nM, respectively. A three-dimensional crystal structure of 7 in complex with BACE-1 revealed that the amino group of the inhibitor core engages the catalytic aspartates in a manner analogous to hydroxyl groups in HE inhibitors. The AE isostere class represents a promising advance in the development of BACE-1 inhibitors.
