    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.

    摘要:
    本发明公开一种光活性六氢喹啉酮及其制备方法。所述光活性六氢喹啉酮式Ⅰ所示化合物和式II所示化合物组成的非对映异构体;式Ⅰ所示化合物的非对映异构体过量值为83%~92%。本发明光活性六氢喹啉酮具有手性环状氨基酯结构,在本发明化合物不饱和酮结构基础上进行衍生反应可以合成多种具有不同取代基的环状氨基酯类化合物,因此这些结构多样的手性环状氨基酯具有潜在的生物活性,可以为一些药物的合成提供有用的前体结构。另外,当手性环状氨基酯发生水解反应后,可以生成相应的手性环状氨基酸,而氨基酸在生物体维持正常运转不可或缺的重要成分,所以相应的具有新颖结构的环状氨基酸可能会参与和影响生物体信息的复制、转移和表达等过程,从而表现出不同寻常的生物活性。
