good ex vivo anti-fXa activity upon oral administration in rats. However, it has been revealed that 1 had low metabolic stability against human liver microsomes. To improve the metabolic stability, we attempted to modify the S1 and S4 ligands of 1. These modifications resulted in compound 34b, which exhibited selective anti-fXa activity and excellent anti-coagulation activity.
在大鼠中口服给药时,丝氨酸蛋白酶因子xa(fXa)抑制剂1表现出良好的离体抗fXa活性。但是,已经发现1对人肝微粒体的代谢稳定性低。为了改善代谢稳定性,我们尝试修饰1的S1和S4配体。这些修饰产生了化合物34b,该化合物具有选择性的抗fXa活性和出色的抗凝血活性。
