Intravascular clot formation is an important factor in a number of cardiovascular diseases. Therefore, the prevention of blood coagulation has become a major target for new therapeutic agents. One attractive approach is the inhibition of factor Xa (FXa), which is a key enzyme in coagulation cascade responsible for the generation of thrombin by limited proteolysis of its zymogen, prothrombin. We have investigated
血管内血块的形成是许多心血管疾病的重要因素。因此,预防凝血已成为新治疗剂的主要目标。一种有吸引力的方法是抑制因子Xa(FXa),它是凝血级联反应中的关键酶,可通过其酶原,凝血酶原的有限蛋白水解而产生凝血酶。我们研究了包含4-(哌啶子基)吡啶基团取代胍基和/或a基团的1-芳基磺酰基-3-哌嗪酮衍生物,并发现了化合物M55113(30a:4-[(6-氯-2-萘基)磺酰基] -1-[[[1-(4-吡啶基)-4-哌啶基]甲基]哌嗪酮),作为FXa的强效抑制剂(IC50 = 0.06 microM),对FXa的选择性比胰蛋白酶和凝血酶高。
