already reported unique compounds containing a N,O-spiro acetal structure as an orally active factor Xa (FXa) inhibitor. This time, we described a N,N-spiro acetal structure as an analogue of the N,O-spiro acetal structure for an orally active FXa inhibitor. The synthesis of these analogues could be achieved in a similar fashion to the N,O-spiro acetal synthesis. Consequently, FXa inhibitory activity was
我们已经报道了含有N,O-螺缩醛结构作为口服活性因子Xa(FXa)抑制剂的独特化合物。这次,我们将N,N-螺缩醛结构描述为口服活性FXa抑制剂的N,O-螺缩醛结构的类似物。这些类似物的合成可以以类似于N,O-螺缩醛合成的方式实现。因此,FXa抑制活性增加,可以发现更多的活性化合物(M58163:IC50 = 0.61 nM,M58169:IC50 = 0.58 nM)。另外,绝对构型可以通过X射线晶体学分析(M58169:(R)-构型)确定。
