Abstract

On the purpose of searching for the structure-activity relationship (SAR) and obtaining novel anti-platelet drugs, 41 4-methoxybenzene-1,3-isophthalamides have been described the synthesis process and in vitro activities on anti-platelet aggregation. The target compounds have been classified into four series: series 1 (ortho-substituted phenyl: 1a-1j), series 2 (meta-substituted phenyl: 2a-2k), series 3 (para-substituted phenyl: 3a-3l) and series 4 (aromatic of no substituted group and aromatic heterocyclic substituted groups: 4a-4h). The chemical structures of the target compounds were confirmed by MS, IR, (1)H NMR, and their in vitro activities on anti-platelet aggregation were tested and assessed by using Born test. The result showed that thirteen compounds 1c, 1d, 1i, 1j, 2g, 3a, 3c, 3d, 3f, 3h, 3l, 4b and 4c have superior anti-platelet aggregation activities than the reference drug Picotamide.Copyright © 2012 Elsevier Ltd.
