[Design, synthesis, and biological evaluation of phenylpropenamides compounds as anti-platelet aggregation].

Twenty phenylpropenamide analogs with structural novelty were designed and synthesized upon pharmacophore-combination strategy. The structures of target compounds were elucidated by IR, 1H NMR, 13C NMR and MS, and all the target compounds were biologically evaluated for the inhibitory activities of platelet aggregation induced by adenosine diphoshate（ADP） and（AA） arachidonic acid via Bron method. As a result, compounds 6b, 9b, 9d and 9h demonstrated potent inhibitory activity against platelet aggregation induced by AA. Meanwhile, compounds 6b, 6d, 6j, 9b and 9g exhibited significant suppression of platelet aggregation induced by ADP.
