Based upon the biphenyl 1-(2-naphthyl)-1H-pyrazole-5-carboxylamides reported in our previous communications, we designed and discovered 2-(6-chloro-3-methylsulfonyl)-naphthyl as an optimal factor Xa S1 binding element. Employing a key Diels–Alder reaction of 1,4-dihydro-2,3-benzoxathiin-3-oxide with maleic anhydride and a key Cu(I)-mediated methylsulfonylation, we prepared two biphenyl 1-(2-(6-chloro-3-methylsulfonyl)-naphthyl)-1H-pyrazole-5-carboxylamides as highly potent factor Xa inhibitors with Ki values of 0.065 nM and 0.045 nM respectively, and demonstrated the synergistically enhanced binding interaction in the factor Xa S1 site.
基于我们之前的通讯报道的双苯并[b,f][1,4]氧氮杂卓-1-(2-萘基)-1H-吡唑-5-羧酰胺类化合物,我们设计并发现了2-(6-氯-3-甲磺酰基)萘基作为优选的因子Xa S1结合元件。通过使用1,4-二氢-2,3-苯并噻嗪-3-氧化物与马来酸酐的关键Diels-Alder反应和关键的Cu(I)介导的甲磺酰化反应,我们制备了两种双苯并[b,f][1,4]氧氮杂卓-1-(2-(6-氯-3-甲磺酰基)萘基)-1H-吡唑-5-羧酰胺,它们作为高效的因子Xa抑制剂,其Ki值分别为0.065 nM和0.045 nM,并展示了在因子Xa S1位点协同增强的结合相互作用。
