This manuscript describes the preparation of dabigatran derivatives and their inhibitory potentials toward human thrombin. Among the tested compounds, 7c, 7k, 7m and 7o, with IC50 values of 1.54, 0.84, 1.18 and 1.42 nM, exhibited comparable inhibitory activity to dabigatran (IC50 = 1.20 nM). The in vivo anti-thrombotic activity of compounds 7c and 7o in SD rats was studied. Results showed that intravenously
该手稿描述了达比加群衍生物的制备及其对人凝血酶的抑制潜力。在测试的化合物中,IC 50值为1.54、0.84、1.18和1.42 nM的7c,7k,7m和7o表现出与达比加群相当的抑制活性(IC 50 = 1.20 nM)。化合物7c和7o的体内抗血栓形成活性在SD大鼠中进行了研究。结果表明,静脉内施用这两种化合物可显着抑制血栓的生长,抑制率分别为(84.24±1.53)%和(84.57±0.45)%,与达比加群(85.07±0.61)%相当。此外,活性化合物(7k和7m)的对接模拟提供了潜在的结合模型。结果表明,可以进一步研究这些化合物以确定其抗凝活性。
