Highly potent macrocyclic BACE-1 inhibitors incorporating a hydroxyethylamine core : Design, synthesis and X-ray crystal structures of enzyme inhibitor complexes

On the day of the defence day the status of this article was Manuscript.
A series of P1-P3 linked macrocyclic BACE-1 inhibitors containing a hydroxyethylamine (HEA) isostere scaffold has been synthesized. All inhibitors comprise a toluene or N-phenylmethanesulfonamide P2 moiety. Excellent BACE-1 potencies, both in enzymatic and cell-based assays, were observed in this series of target compounds, with the best candidates displaying cell-based IC50 values in the low nanomolar range. As an attempt to improve potency, a phenyl substituent aiming at the S3 subpocket was introduced in the macrocyclic ring. X-ray analyses were performed on selected compounds, and enzyme-inhibitor interactions are discussed.
