Abstract

In this work, we report a series of new 4-oxo-1,4-dihydro-quinoline-3-carboxamide derivatives as β-secretase (BACE-1) inhibitors. Supported by docking study, a small library of derivatives were designed, synthesized and biologically evaluated in vitro. The studies revealed that the most potent analog 14e (IC50 = 1.89 μM) with low cellular cytotoxicity and high predicted blood brain barrier permeability, could serve as a good structure for further modification.
