Abstract:
This Letter describes the de novo design of non-peptidic hydroxyethylamine (HEA) inhibitors of BACE-1 by elimination of P-gp contributing amide attachments. The predicted binding mode of the novel cyclic sulfone HEA core template was confirmed in a X-ray co-crystal structure. Inhibitors of sub-micromolar potency with an improved property profile over historic HEA inhibitors resulting in improved brain penetration are described.
