A set of ortho-, meta- and para-substituted cinnamic hydroxamic acids (CHAs) was synthesized. In each series of structural isomers, a phenyl substituent was linked to an aromatic ring of the parent cinnamic acid via a linker of one to four atoms in length. Using a cell test system with the full-length replicon of hepatitis C virus (HCV), we established a relationship between the suppression of HCV
合成了一组邻,间和对位的肉桂酸异羟肟酸(CHA)。在各系列结构异构体中,苯基取代基通过长度为1-4个原子的连接基与母体肉桂酸的芳环连接。使用带有丙型肝炎病毒全长复制子的细胞测试系统,我们建立了抑制HCV复制子繁殖与抑制I / IIb类组蛋白脱乙酰基酶(HDAC)之间的关系。在邻位CHA的情况下,抗HCV活性与HDAC8的抑制作用有关,而在meta-CHA的情况下,其与HDAC1 / 2/3和HDAC6的抑制作用有关。对-CHA的抗病毒活性比间-CHA的抗病毒活性强很多倍,而HDAC1 / 2/3/6的抑制效率几乎相同,
