Abstract

A series of 2-piperazin-1-yl-quinazolines were synthesized and evaluated for their antiaggregative activity. The synthesized small molecule compounds have potently inhibited platelet aggregation in vitro and blocked FITC-Fg binding to αIIbβ3 Integrin in a suspension of washed human platelets. The key αIIbβ3 protein-ligand interactions were determined in docking experiments and some correlations have been observed between values of the affinity and docking scores.
