Abstract

The Hepatitis B Virus (HBV) ribonuclease H (RNaseH) is a promising but unexploited drug target. Here, we synthesized and analyzed a library of 57 amide-containing α-hydroxytropolones (αHTs) as potential leads for HBV drug development. Fifty percent effective concentrations ranged from 0.31 to 54 μM, with selectivity indexes in cell culture of up to 80. Activity against the HBV RNaseH was confirmed in semi-quantitative enzymatic assays with recombinant HBV RNaseH. The compounds were overall poorly active against human ribonuclease H1, with 50% inhibitory concentrations of 5.1 to >1,000 μM. The αHTs had modest activity against growth of the fungal pathogen Cryptococcus neoformans, but had very limited activity against growth of the Gram - bacterium Escherichia coli and the Gram + bacterium Staphylococcus aureus, indicating substantial selectivity for HBV. A molecular model of the HBV RNaseH templated against the Ty3 RNaseH was generated. Docking the compounds to the RNaseH revealed the anticipated binding pose with the divalent cation coordinating motif on the compounds chelating the two Mn++ ions modeled into the active site. These studies reveal that that amide αHTs can be strong, specific HBV inhibitors that merit further assessment toward becoming anti-HBV drugs.

抽象

乙型肝炎病毒(HBV)核糖核酸酶H(RNaseH)是一种有前途但未开发的药物靶标。在这里,我们合成并分析了含有57酰胺的α-羟基对苯二酚(αHTs)库,作为HBV药物开发的潜在先导。 50%的有效浓度范围为0.31至54μM,在细胞培养中的选择性指数高达80。针对HBV RNaseH的活性在重组HBV RNaseH的半定量酶分析中得到了证实。这些化合物总体上对人核糖核酸酶H1的活性较弱,抑制浓度为50%,范围为5.1至>1,000μM。 αHTs对真菌病原体新隐球菌的生长具有适度的活性,但对革兰氏大肠杆菌和金黄色葡萄球菌的生长具有非常有限的活性,表明对HBV有相当大的选择性。生成了针对Ty3 RNaseH模板化的HBV RNaseH的分子模型。将化合物与RNaseH对接后,显示出预期的结合姿势,即化合物上的二价阳离子配位基螯合了被建模为活性位点的两个Mn ++离子。这些研究表明,酰胺αHTs可能是强的,特异性的HBV抑制剂,值得进一步评估,以成为抗HBV药物。
