Intravascular clot formation is an important event in a number of cardiovascular diseases. The prevention of blood coagulation has become a major target for new therapeutic agents. Factor Xa (FXa) is a trypsin-like serine protease that plays a key role in the blood coagulation cascade and represents an attractive target for anticoagulant drug development. We have investigated substituents in the central part of a lead compound (3: M55113), and discovered that compound M55551 (34: (R)-4-[(6-Chloro-2-naphthalenyl)sulfonyl]-6-oxo-1-[[1-(4-pyridinyl)-4-piperidinyl]methyl]-2-piperazinecarboxylic acid) is a potent inhibitor of FXa (IC50=0.006 μM), with high selectivity for FXa over trypsin and thrombin. The activity of this compound is ten times more powerful than the lead compound.
血管内血块形成是多种心血管疾病中的一个重要事件。防止血液凝固已成为新治疗药物的重要目标。因子Xa(FXa)是一种类似胰蛋白酶的丝氨酸蛋白酶,在血液凝固级联反应中发挥关键作用,因此是抗凝药物开发的理想靶点。我们研究了先导化合物(3:M55113)中央部分的取代基,发现化合物M55551(34:(R)-4-[(6-氯-2-萘基)磺酰]-6-氧-1-[[1-(4-吡啶基)-4-哌啶基]甲基]-2-哌嗪羧酸)是FXa的强效抑制剂(IC50=0.006 μM),对FXa相较于胰蛋白酶和血栓素具有很高的选择性。该化合物的活性是先导化合物的十倍。
