A novel series of 3-[2-[(4-carbamimidoylphenylamino)methyl]-1-substituted-1H-benzoimidazole-5-carbonyl}(3-chloro-4-fluorophenyl)amino]propionic derivatives of dabigatran was synthesized. The structures of the compounds were characterized by 1H NMR, 13C NMR, HRMS, and elemental analysis. The compounds were screened for in vitro thrombin inhibitory activity. The results indicated that the compounds had low to moderate inhibitory activity. The compounds with N-methyl and N-ethyl side chains had much greater inhibitory activity against thrombin than those with other side chains.
合成了一系列新型 3-[2-[(4-氨基甲酰基苯基氨基)甲基]-1-取代-1H-苯并咪唑-5-甲酰基}(3-氯-4-氟苯基)氨基]丙酸达比加群衍生物。化合物的结构通过 1H NMR、13C NMR、HRMS 和元素分析进行了表征。对化合物进行了体外凝血酶抑制活性筛选。结果表明,这些化合物具有低度到中度的抑制活性。具有 N-甲基和 N-乙基侧链的化合物对凝血酶的抑制活性远高于具有其他侧链的化合物。
