Factor Xa, a serine protease, is at the critical juncture between the intrinsic and extrinsic pathways of the coagulation cascade. Inhibition of factor Xa has the potential to provide effective treatment for both venous and arterial thrombosis. We recently described a series of meta-substituted phenylpyrazoles that are highly potent, selective, and orally bioavailable factor Xa inhibitors. In this
Xa因子是一种丝氨酸蛋白酶,处于凝血级联的内在和外在途径之间的关键时刻。抑制因子Xa有可能为静脉和动脉血栓形成提供有效的治疗。我们最近描述了一系列间位取代的苯基吡唑类,它们是高效,选择性和口服生物利用因子Xa抑制剂。在本文中,我们报告了我们为进一步优化Xa因子抑制剂与一系列邻位和/或对位取代的苯基吡唑衍生物的选择性而做出的努力。最有效的化合物显示出Xa因子的亚纳摩尔抑制常数,并且对其他丝氨酸蛋白酶的选择性超过1000倍。这些化合物在动静脉分流血栓形成的兔子模型中也是有效的。
