Title:

Improving the permeability of the hydroxyethylamine BACE-1 inhibitors: structure-activity relationship of P2' substituents.

Bioorg Med Chem Lett. 2010 Aug 15;20(16):4789-94. Epub 2010 Jun 25.

Abstract:

Herein we describe further evolution of hydroxyethylamine inhibitors of BACE-1 with enhanced permeability characteristics necessary for CNS penetration. Variation at the P2' position of the inhibitor with more polar substituents led to compounds 19 and 32, which retained the potency of more lipophilic analog 1 but with much higher observed passive permeability in MDCK cellular assay.
