本文报道了4-氧代四氢嘧啶衍生的苯基脲类化合物作为新型B型肝炎病毒(HBV)衣壳组装调节剂的合成和评价。在这些衍生物中,化合物27(58031)和几个类似物显示出亚微摩尔EC 50的抗HBV活性和低细胞毒性(>50 μM)。结构-活性关系研究揭示了对4-氧代四氢嘧啶的5位上的额外基团的耐受性。机制研究表明化合物27(58031)是一种II型核心蛋白变构调节剂(CpAMs),它诱导核心蛋白二聚体组装成空衣壳,在天然琼脂糖凝胶中具有快速的电泳迁移率。因此,这些化合物可以作为未来开发新型抗HBV药物的先导。
We report herein the synthesis and evaluation of phenyl ureas derived from 4-oxotetrahydropyrimidine as novel capsid assembly modulators of hepatitis B virus (HBV). Among the derivatives, compound 27 (58031) and several analogs showed an activity of submicromolar EC50 against HBV and low cytotoxicities (>50 μM). Structure–activity relationship studies revealed a tolerance for an additional group at position 5 of 4-oxotetrahydropyrimidine. The mechanism study indicates that compound 27 (58031) is a type II core protein allosteric modulator (CpAMs), which induces core protein dimers to assemble empty capsids with fast electrophoresis mobility in native agarose gel. These compounds may thus serve as leads for future developments of novel antivirals against HBV.
