  Synthesis and biological evaluation of α-ketoamides as inhibitors of the Dengue virus protease with antiviral activity in cell-culture

  摘要：

  The development of small molecule inhibitors of the viral protease is of considerable interest for the treatment of emergent flaviviral diseases such as Dengue or West Nile fever. Until today little progress has been made in finding drug-like compounds that inhibit the protease and provide a starting point for lead optimization. We describe here the initial steps of a drug discovery effort that focused on the styryl pharmacophore, combined with a ketoamide function to serve as electrophilic trap for the catalytic serine. This resulted in a fragment-like lead compound with reasonable target affinity and good ligand efficiency, which was extensively modified to explore structure-activity relationships. Selected compounds were cross-tested against the West Nile virus protease and thrombin, indicating that selectivity for one or more flaviviral proteases can be achieved. Finally, the antiviral activity of several protease inhibitors was confirmed in a cell-culture model of Dengue virus replication. The SAR presented here may serve as starting point for further drug discovery efforts with the aim of targeting flaviviral proteases. (C) 2011 Elsevier Ltd. All rights reserved.

  We report an iridium-catalyzed asymmetric hydrogenation reaction for the preparation of chiral homophenylalanine derivatives. Catalyzed by an iridium/f-amphox complex, the asymmetric hydrogenation of styrylglyoxylamides was conducted smoothly with turnover numbers of up to 10,000 and up to 98% ee. This method was successfully applied in a synthesis of a fragment of benazepril, a drug used for the treatment

  我们报告了用于制备手性高苯丙氨酸衍生物的铱催化不对称氢化反应。在铱/f-amphox 络合物的催化下，苯乙烯基乙醛酰胺的不对称氢化顺利进行，转化率高达 10,000，ee 高达 98%。该方法已成功应用于苯那普利片段的合成，这是一种用于治疗高血压的药物。
