'''Crystal structure of beta-secretase complexed with an amino-ethylene inhibitor'''<br />


==Overview==
==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.
