本発明は活性化血液凝固第 X因子(FXa)を阻害して抗凝固作用ならびに抗血 栓作用を有する、 動脈および静脈の血栓閉塞性疾患、 炎症、 癌などの予防および 治療に有用な新規ィミダゾピリジン誘導体、 その製造方法および用途に関する。 背景技術  The present invention provides a novel imidazopyridine useful for the prevention and treatment of arterial and venous thromboembolic diseases, inflammation, cancer, etc., which have an anticoagulant effect and an antithrombotic effect by inhibiting activated blood coagulation factor X (FXa). The present invention relates to a derivative, a production method and a use thereof. Background art
心筋梗塞、 脳梗塞等の予防および治療には血栓の形成を抑制することが重要で あり、 血栓抑制剤として抗トロンビン剤、 血小板凝集阻害剤等の研究開発が種々 行われている。 しかしながら、 血小板凝集阻害剤はもちろん、 抗トロンビン剤も 抗凝固作用と共に血小板の凝集を抑制することから、 これらの薬剤は副作用とし て出血傾向等を示し、 その安全性に問題がある。一方、 FXa阻害剤は、 特異的に 凝固因子のみを阻害するため安全な抗凝固剤になると考えられている。  In order to prevent and treat myocardial infarction and cerebral infarction, it is important to suppress the formation of thrombus. Research and development of antithrombin agents, platelet aggregation inhibitors, etc. are being conducted as thrombus inhibitors. However, not only platelet aggregation inhibitors, but also antithrombin agents suppress platelet aggregation together with their anticoagulant effect, so these agents show bleeding tendency as a side effect, and their safety is problematic. On the other hand, FXa inhibitors are considered to be safe anticoagulants because they specifically inhibit only coagulation factors.
