Discovery of (1<i>H</i>-Pyrazolo[3,4-<i>c</i>]pyridin-5-yl)sulfonamide Analogues as Hepatitis B Virus Capsid Assembly Modulators by Conformation Constraint
HepatitisBvirus (HBV) capsidassemblymodulators (CAMs) have been suggested to be effective anti-HBV agents in both preclinical and clinical studies. In addition to blocking HBV replication, CAMs could reduce the formation of covalently closed circular DNA (cccDNA), which accounts for the persistence of HBV infection. Here, we describe the discovery of (1H-indazole-5-yl)sulfonamides and (1H-pyrazolo[3
在临床前和临床研究中,均已建议乙型肝炎病毒(HBV)衣壳装配调节剂(CAMs)是有效的抗HBV药物。除了阻断HBV复制外,CAM还可以减少共价闭合环状DNA(cccDNA)的形成,这说明了HBV感染的持续性。在这里,我们通过限制氨基磺酰基苯甲酰胺衍生物的构象,描述了作为新的CAM化学型的(1 H-吲唑-5-基)磺酰胺和(1 H-吡唑并[3,4- c ]吡啶-5-基)磺酰胺的发现。 。铅优化导致化合物56的EC 50值为0.034μM,在小鼠肝微粒体中具有良好的代谢稳定性。为了增加溶解度,氨基酸前药(制备65)及其柠檬酸盐(67)。在基于水动力注射的HBV感染小鼠模型中,化合物67剂量依赖性地抑制HBV复制,而56则由于其次优溶解性而未显示体内抗HBV活性。这类化合物可作为开发新型抗HBV药物的起点。
