摘要:
Using structure-guided design, hydroxyethylamine BACE-1 inhibitors were optimized to nanomolar A beta cellular inhibition with selectivity against cathepsin-D. X-ray crystallography illuminated the S1' residues critical to this effort, which culminated in compounds 56 and 57 that exhibited potency and selectivity but poor permeability and high P-gp efflux.
