A series of aryl-or aralky-substituted 2-amino-3, 4-dihydroquinazolines and related compounds were synthesized. The compounds were evaluated for inhibitory activity towards collagen-and ADP-induced aggregation of rat blood platelet in vitro and ex vivo. A group of 3-benzyl-substituted derivatives had potent activity. The structure-activity relationships are discussed.
合成了一系列含有苯基或苯甲基取代的2-氨基-3,4-二氢喹唑啉及其相关化合物。这些化合物在体外和体内对大鼠血小板胶原和ADP诱导的聚集具有抑制活性,其中一类3-苄基取代的衍生物表现出较强的活性。相关结构与活性的关系进行了探讨。
