4-tetrahydrobenzo[4,5]imidazo[1,2-a]pyrazin-1-yl)methyl)benzimida-mide (I-1∼I-2, II-1∼II-8) were designed, synthesized and evaluated for their inhibitory effect on human thrombin. Compound II-7 (IC50 = 82.8 nM), which showed the strongest thrombin inhibitory activity among the tested compounds, was chosen as the lead compound, and ten carbamate derivatives (II-9a∼II-13a, II-9b∼II-12b, II-14) were prepared and
((1,2,3,4-四氢苯并[4,5]咪唑并[1,2-a]吡嗪-1-基)甲基)benzimida-酰胺( - 4十衍生物I-1 〜I-2 ,II -1〜II-8 )设计,合成并评价了对人凝血酶的抑制作用。化合物II-7(IC 50 = 82.8纳米),这表明所测试的化合物中最强的凝血酶的抑制活性,被选为铅化合物,和10氨基甲酸酯衍生物(II-9A〜II-13A,II-9B〜II- 12b,II-14制备)并评估其抗凝活性。结果表明,大多数测试化合物对凝血酶诱导的血小板凝集具有一定程度的抑制作用,其中化合物II-11a(IC 50 = 8.16μM)和II-14(IC 50 = 1.95μM)显示出更好的抗凝血作用。-血小板凝集活性高于其他。在体内对大鼠静脉血栓形成模型的实验结果还证明化合物II-11A和II-14可显著降低以剂量-响应方式血栓形成。值得指出的是,化合物II-14的效力增强可能是体内水解产生的2-羟甲基-3
