X-ray crystal structure of beta secretase complexed with 2-aminoquinoline
Overview
This paper describes an application of fragment screening to the aspartyl, protease enzyme, beta-secretase (BACE-1), using high throughput X-ray, crystallography. Three distinct chemotypes were identified by X-ray, crystallography as binding to the catalytic aspartates either via an, aminoheterocycle (such as 2-aminoquinoline), a piperidine, or an aliphatic, hydroxyl group. The fragment hits were weak inhibitors of BACE-1 in the, millimolar range but were of interest because most of them displayed, relatively good ligand efficiencies. The aminoheterocycles exhibited a, novel recognition motif that has not been seen before with aspartic, proteases. Virtual screening around this motif identified an aminopyridine, with increased potency and attractive growth points for further, elaboration using structure-based drug design. The companion paper, illustrates how sub-micromolar inhibitors were developed starting from, this fragment.
