Aminoisoquinoline derivatives of the following formulae or analogs thereof and pharmaceutically acceptable salts thereof are provided. These compounds have an excellent effect of inhibiting activated blood-coagulation factor X, and they are useful as anticoagulants or agents for preventing or treating thrombi or emboli.
Benzamidine derivatives of the following formulae or analogs thereof, i.e., pharmaceutically acceptable salts thereof, are provided. These compounds or salts thereof have a blood-coagulation inhibiting effect based on an excellent effect of inhibiting the action of activated blood coagulation factor X, and they are useful as anticoagulants
Described herein are novel methods of preparing a compound of Formula II or a pharmaceutically acceptable salt thereof. In some embodiments, the method is for preparing betrixaban or a pharmaceutically acceptable salt thereof. Also described are compositions comprising substantially pure betrixaban free base or salt thereof.
Aminoisoquinoline derivatives represented by formulae (I and II), analogs thereof or pharmaceutically acceptable salts of the same. Because of having excellent inhibitory effects on activated blood coagulation factor X, these compounds are useful as active ingredients in anticoagulants or preventives/remedies for thrombosis or embolism.
式(I 和 II)代表的氨基异喹啉衍生物、其类似物或其药学上可接受的盐。由于这些化合物对活化的血液凝固因子 X 具有极佳的抑制作用,因此可作为抗凝剂或血栓或栓塞预防/治疗剂的活性成分。
