A series of novel tetrahydropyrazolopyridone derivatives containing 1,3,4-triazole, triazolylmethyl, and partially saturated heterocyclic moieties as P2 binding element was designed, synthesized, and evaluated in vitro for anticoagulant activity in human and rabbit plasma. All compounds showed moderate to significant potency, and compounds 15b, 15c, 20b, 20c, and 22b were further examined for their
设计,合成并评估了一系列新型的包含1,3,4-三唑,三唑基甲基和部分饱和的杂环部分作为P2结合元素的四氢吡唑并吡啶酮衍生物,并在体外评估了其在人和兔血浆中的抗凝血活性。所有化合物均显示出中度至显着的效力,并且进一步检查了化合物15b,15c,20b,20c和22b在体外对人FXa的抑制活性。在体内测试化合物15c和22b的大鼠静脉血栓形成。最有前途的化合物15c具有0.14μM的IC50(FXa)值和98%的抑制率,作为FXa抑制剂值得进一步研究。
