A series of novel 1,2,3,5-tetrahydroimidazo[2,1-b]quinazolin-2-one derivatives substituted with a secondary amino group has been prepared and tested for the activities of inhibiting platelet aggregation in rats in vitro and ex vivo. Most of the compounds were found to be the potent inhibitors of platelet aggregation. Some of the active compounds were soluble in water and effective via iv infusion in
制备了一系列新型的被仲氨基取代的1,2,3,5-四氢咪唑并[2,1-b]喹唑啉-2-酮衍生物,并测试了其在体外和体外对大鼠血小板聚集的抑制作用。体内。发现大多数化合物是血小板聚集的有效抑制剂。一些活性化合物可溶于水,并通过静脉内输注对大鼠有效。结构活性关系表明,位于位置6或7的亲脂性仲氨基有助于保持有效活性。在研究的化合物中,最优选的化合物是7-哌啶子基-1,2,3,5-四氢咪唑并[2,1-b]喹唑啉-2-(13 g,DN-9693)。
