A new aspartic protease inhibitory chemotype bearing a 2-amino-3, 4-dihydroquinazoline ring was identified by high-throughput screening for the inhibition of BACE-1. X-ray crystallography revealed that the exocyclic amino group participated in a hydrogen bonding array with the two catalytic aspartic acids of BACE-1 (Asp32, Asp228). BACE-1 inhibitory potency was increased (0.9 μM to 11 nM K i) by substitution into the unoccupied S1'pocket.
