A series of novel 2,7-disubstituted tetrahydroisoquinoline derivatives were designed and synthesized. Among these derivatives, compounds 1 and 2 exhibited potent inhibitory activity against factor Xa (FXa) and good selectivity with respect to other serine proteases (thrombin, plasmin, and trypsin). In addition, compound 2 exhibited potent anti-FXa activity after intravenous and oral administration
设计并合成了一系列新颖的2,7-二取代的四氢异喹啉衍生物。在这些衍生物中,化合物1和2对Xa因子(FXa)表现出有效的抑制活性,并且对其他丝氨酸蛋白酶(凝血酶,纤溶酶和胰蛋白酶)具有良好的选择性。此外,化合物2在食蟹猴静脉和口服给药后均显示出有效的抗FXa活性,在0.1、0.3和1 mg kg(-1)h(-1)的大鼠模型中显示出剂量依赖性的抗血栓形成作用。静脉血栓形成,并以0.1 mg kg(-1)h(-1)的剂量显着减少了大脑中动脉闭塞模型中脑梗塞的大小。这些结果表明,化合物2(JTV-803)可能同时用作静脉和动脉抗血栓形成剂。
