Design and Synthesis of Potent and Selective BACE-1 Inhibitors
摘要:
Highly potent BACE-1 protease inhibitors have been developed from ill inhibitors containing a hydroxyethylene (HE) core displaying aryloxymethyl or benzyloxymethyl P1 side chain and a methoxy P1' side chain. The target molecules were synthesized in good overall yields from chiral carbohydrate starting materials. The inhibitors show high BACF-1 potency and good selectivity against cathepsin D, where the most potent inhibitor Furnishes BACE-1 Ki << 1 nM and displays > 1000-fold selectivity over cathepsin D.
Discovery of potent BACE-1 inhibitors containing a new hydroxyethylene (HE) Scaffold: Exploration of P1′ alkoxy residues and an aminoethylene (AE) central core
of a new hydroxyethylene (HE) core motif displaying P1 aryloxymethyl and P1′ methoxy substituents delivering potent BACE-1 inhibitors. In a continuation of this work we have now explored the SAR of the S1′ pocket by introducing a set of P1′ alkoxy groups and evaluated them as BACE-1 inhibitors. Previously the P1 and P1′ positions of the classical HE template have been relatively little explored due
