The serine protease factor XI (FXI) is a prominent drug target as it holds promise to deliver efficacious anticoagulation without an enhanced risk of major bleeds. Several efforts have been described targeting the active form of the enzyme, FXIa. Herein, we disclose our efforts to identify potent, selective, and orally bioavailable inhibitors of FXIa. Compound 1, identified from a diverse library of
丝氨酸蛋白酶因子XI(FXI)是一个重要的药物靶标,因为它有望提供有效的抗凝作用而不会增加大出血的风险。已经描述了针对酶的活性形式FXIa的几种努力。本文中,我们公开了我们为确定有效,选择性和口服生物利用性FXIa抑制剂而做出的努力。化合物1从内部丝氨酸蛋白酶抑制剂的各种文库中鉴定出来的肽原本被设计为补体因子D抑制剂,并表现出亚微摩尔FXIa活性和令人鼓舞的吸收,分布,代谢和排泄(ADME)特性,同时缺乏拟肽结构。通过基于结构的药物设计和传统药物化学相结合,FXIa的S1,S1β和S1'口袋中相互作用的最优化导致发现具有FXIa亚纳摩尔效价,对其他凝血蛋白酶的选择性增强的化合物23,以及临床前药代动力学(PK)资料与患者的两次给药一致。
