Factor Xa (fXa) is a crucial player in various thromboembolic disorders. Inhibition of fXa can provide safe and effective antithrombotic effects. In this study, a series of anthranilamide compounds were designed by utilizing structure-based design strategies. Optimization at P1 and P4 groups led to the discovery of compound 16g: a highly potent, selective fXa inhibitor with pronounced in vitro anticoagulant
Xa因子(fXa)是各种血栓栓塞性疾病的关键因素。抑制fXa可以提供安全有效的抗血栓形成作用。在这项研究中,通过利用基于结构的设计策略设计了一系列邻氨基苯甲酰胺化合物。P 1和P 4组的优化导致发现化合物16g:一种具有显着体外抗凝活性的高效,选择性fXa抑制剂。此外,16g在大鼠静脉血栓形成(VT)和动静脉分流(AV-SHUNT)模型中也显示出出色的体内抗血栓形成活性。出血风险评估表明16g剂量分别为1 mg / kg和5 mg / kg时,比贝曲沙班更安全。另外,16g也表现出令人满意的PK曲线。最终,选择16g来研究其对缺氧-再充氧诱导的H9C2细胞活力的影响。MTT结果表明,16g可以显着降低H9C2细胞的活力。
