4DH6 - PubMed Abstract:
A series of potent hydroxyethyl amine (HEA) derived inhibitors of β-site APP cleaving enzyme (BACE1) was optimized to address suboptimal pharmacokinetics and poor CNS partitioning. This work identified a series of benzodioxolane analogues that possessed improved metabolic stability and increased oral bioavailability. Subsequent efforts focused on improving CNS exposure by limiting susceptibility to Pgp-mediated efflux and identified an inhibitor which demonstrated robust and sustained reduction of CNS β-amyloid (Aβ) in Sprague-Dawley rats following oral administration.
