studies on the synthesis and antiplatelet activity of coumarin derivatives of α-methylidene-γ-butyrolactones, certain quinoline, flavone, and xanthone derivatives were synthesized and evaluated for antiplatelet activity against thrombin (Thr)-, arachidonic acid (AA)-, collagen (Col)-, and platelet-activating factor (PAF)-induced aggregation in washed rabbit platelets. These compounds were synthesized
作为我们先前对α-亚甲基-γ-丁内酯香豆素衍生物的合成和抗血小板活性的研究的继续,合成了某些喹啉,黄酮和x吨酮衍生物并评估了其对凝血酶(Thr)-,花生四烯酸( AA),胶原蛋白(Col)和血小板活化因子(PAF)诱导的兔兔血小板聚集。这些化合物分别通过烷基化和Reformatsky型缩合反应分别由喹啉8-醇,黄酮7-醇和黄酮3-醇合成(方案1-3)。通过与香豆素α-亚甲基-γ-丁内酯3a,黄酮和x吨酮衍生物3b和3c的比较分别具有更强的选择性,其中仅AA和胶原蛋白诱导的聚集被强烈抑制。大多数喹啉衍生物(9a–e)表现出广谱抗血小板活性。
