The synthesis and structure–activity relationship of substituted N-phenyl anthranilic acid analogs as amyloid aggregation inhibitors

It is believed that β-amyloid aggregation is an important event in the development of Alzheimer’s disease. In the course of our studies to identify β-amyloid aggregation inhibitors, a series of N-phenyl anthranilic acid analogs were synthesized and studied for β-amyloid inhibition activity. The synthesis, structure–activity relationship, and in vivo activity of these analogs are discussed.
