evaluation of their pharmacological activities. These compounds showed significant inhibition of platelet aggregation and some of them possessed a protective against endothelial cell injury. Structure-activity relationship studies indicated that 2b, 2d and 3b are potent inhibitors of platelet aggregation induced by arachidonic acid (AA) with an IC50 in the range of 1-10 micrograms/ml. Among them, 3b
合成了两个新的2-芳基甲基-1,4-苯醌(2和3)系列,以评估其药理活性。这些化合物显示出对血小板聚集的显着抑制作用,并且其中一些具有对内皮细胞损伤的保护作用。结构-活性关系研究表明,2b,2d和3b是花生四烯酸(AA)诱导的血小板聚集的有效抑制剂,IC50范围为1-10微克/毫升。其中,3b对1 microM的过氧化氢(H2O2)引起的内皮细胞损伤具有显着的抑制活性。
