Abstact

A set of low molecular weight compounds containing a hydroxyethylamine (HEA) core structure with different prime side alkyl substituted 4,5,6,7-tetrahydrobenzazoles and one 4,5,6,7-tetrahydropyridinoazole was synthesized. Striking differences were observed on potencies in the BACE-1 enzymatic and cellular assays depending on the nature of the heteroatoms in the bicyclic ring, from the low active compound 4 to inhibitor 6, displaying BACE-1 IC(50) values of 44 nM (enzyme assay) and 65 nM (cell-based assay).
