  Inhibition of norovirus 3CL protease by bisulfite adducts of transition state inhibitors

  摘要：

  Noroviruses are the most common cause of acute viral gastroenteritis, accounting for >21 million cases annually in the US alone. Norovirus infections constitute an important health problem for which there are no specific antiviral therapeutics or vaccines. In this study, a series of bisulfite adducts derived from representative transition state inhibitors (dipeptidyl aldehydes and alpha-ketoamides) was synthesized and shown to exhibit anti-norovirus activity in a cell-based replicon system. The ED50 of the most effective inhibitor was 60 nM. This study demonstrates for the first time the utilization of bisulfite adducts of transition state inhibitors in the inhibition of norovirus 3C-like protease in vitro and in a cell-based replicon system. The approach described herein can be extended to the synthesis of the bisulfite adducts of other classes of transition state inhibitors of serine and cysteine proteases, such as alpha-ketoheterocycles and alpha-ketoesters.

  accommodates the P3 position. Alternative binding is induced by polar P3 groups or a nearby methyl. NMR and solubility studies with GC376 show that it exists as a mixture of stereoisomers and forms colloids in aqueous media at higher concentrations, a property not previously reported. Replacement of its Na+ counter ion with choline greatly increases solubility. The physical, biochemical, crystallographic

  SARS-CoV-2（引起 COVID-19 的冠状病毒）的复制需要主要蛋白酶 (M pro ) 来裂解病毒蛋白。因此，M pro是抗病毒药物的靶标。我们和其他人之前证明，GC376 是一种亚硫酸氢盐前药，在动物中具有抗冠状病毒作用，是 SARS-CoV-2 中 M pro的有效抑制剂。在这里，我们报告了改进的 GC376 衍生物的结构活性研究，其具有纳摩尔亲和力和治疗指数 >200。抑制剂-M pro复合物的晶体结构表明，M pro中的另一个结合袋（S4）可容纳 P3 位置。替代结合是由极性 P3 基团或附近的甲基诱导的。 GC376 的 NMR 和溶解度研究表明，它以立体异构体的混合物形式存在，并在较高浓度的水介质中形成胶体，这一特性以前未曾报道过。用胆碱代替其Na +抗衡离子大大增加了溶解度。物理、生化、晶体学和细胞数据揭示了 M pro抑制剂设计的新途径。
