A novel series of triaryloxypyridines have been designed to inhibit factor Xa, a serine protease strategically located in the coagulation cascade. Inhibitor 5e has a K(I) against factor Xa of 0.12nM and is greater than 8000- and 2000-fold selective over two related serine proteases, thrombin and trypsin, respectively. The 4-position of the central pyridine has been identified as a site that tolerates
已经设计了一系列新的三芳氧基吡啶,以抑制因子Xa,Xa是战略性地位于凝血级联反应中的丝氨酸蛋白酶。抑制剂5e对Xa因子的K(I)为0.12nM,对两种相关的丝氨酸蛋白酶(凝血酶和胰蛋白酶)的选择性大于8000倍和2000倍。中央吡啶的4-位已被鉴定为可耐受各种取代而对效能和选择性没有有害影响的位点。这表明吡啶环的4-位是化学修饰以鉴定具有改善的药代动力学特征的抑制剂的理想位点。该研究产生了抑制剂5d,其在狗中的口服利用率为6%。概述了这类抑制剂的合成,体外活性和体内特性。
