凝血因子Ⅹa是一个丝氨酸蛋白酶,在凝血级联反应中,因子Ⅹa处于外源性和内源性凝血级联反应的交汇点,也就是凝血瀑布共同通路的起始位置。由于其在凝血途径中位置的重要性,Ⅹa因子已经成为新型抗凝药物开发的重要靶点。本文从凝血因子Ⅹa的功能和结构、已上市Ⅹa因子抑制剂以及天然来源的Xa因子抑制剂等方面进行综述。
Factor Xa(FXa) is a serine protease playing a pivotal role in the blood coagulation cascade. It occupied the central position that is the convergence point of intrinsic and extrinsic pathways,sand it has become an attractive biologic target in the discovery and development of new active anticoagulant agents. In this review,we will illustrate the structure and function of FXa,the widely used FXa inhibitors and potent FXa inhibitors from natural resources.
