  Design, Synthesis, and Biological Activity of Potent and Selective Inhibitors of Blood Coagulation Factor Xa

  摘要：

  Factor Xa (FXa) has materialized as a key enzyme for the intervention of the blood coagulation cascade and for the development of new antithrombotic agents. FXa is the lone enzyme responsible for the production of thrombin and therefore is an attractive target for the control of thrombus formation. We have designed and synthesized a unique series of quinoxalinone FXa inhibitors. This series resulted in 3-{4-[5-((2S,6R)-2,6-dimethylpiperidin-1-yl)pentyl]-3oxo-3,4-dihydroquinoxolin-2-yl}benzamidine (35) with 0.83 nM activity against FXa and excellent selectivity over similar serine proteases. An X-ray crystal structure of compound 35 bound to trypsin along with molecular modeling has led to a predicted binding conformation of compound 35 in FXa. Compound 35 has also been proven to be efficacious in vivo in both the rabbit veno-venous shunt and dog electrolytic injury models. In addition, it was shown that compound 35 did not significantly increase bleeding times in a rabbit model except at the highest doses and plasma concentrations were elevated in a dose dependent manner following a bolus dose and continuous intravenous infusion.

• High-Potency Phenylquinoxalinone Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) Activators

  We previously identified phenylquinoxalinone CFTRact-J027 (4) as a cystic fibrosis transmembrane conductance regulator (CFTR) activator with an EC50 of ∼200 nM and demonstrated its therapeutic efficacy in mouse models of constipation. Here, structure–activity studies were done on 36 synthesized phenylquinoxalinone analogs to identify compounds with improved potency and altered metabolic stability.

  我们之前鉴定出苯基喹喔啉酮CFTR act -J027（4）为EC 50为〜200 nM的囊性纤维化跨膜电导调节剂（CFTR）激活剂，并证明了其在便秘小鼠模型中的治疗效果。在这里，对36种合成的苯基喹喔啉酮类似物进行了结构活性研究，以鉴定具有增强的效力和改变的代谢稳定性的化合物。苯基喹喔啉酮核的合成通常通过1,2-苯二胺与取代的苯基氧乙酸酯的缩合来完成。结构活性研究除其他功能外，还确定了在3-芳基上适当定位的硝基部分的优先性质。与之相比，合成的类似物显示出更高的CFTR激活能力4的EC 50降至21 nM，具有更高的代谢稳定性。CFTR激活剂在便秘，干眼症，胆汁淤积性肝病和炎症性肺疾病中具有潜在的治疗适应症。

  日期：——

  Two scaffolds, namely benzimidazole and quinoxalin2(1H)-one, were synthesized by treating 2-(N-Boc-amino)phenylisocyanide (Boc: tert-butoxycarbonyl) with carboxylic acids and glyoxylic acids, respectively. The target compounds were generated directly after two-component coupling, deprotection, and intermolecular cyclization.
