The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Covid-19 pandemic has caused high morbidity and mortality rates worldwide. Virus entry into cells can be blocked using several strategies, including inhibition of protein-protein interactions (PPIs) between the viral spike glycoprotein and cellular receptors, as well as blocking of spike protein conformational changes that are required for cleavage/activation and fusogenicity. The spike-mediated viral attachment and entry into cells via fusion of the viral envelope with cellular membranes involve PPIs mediated by short peptide fragments exhibiting particular secondary structures. Thus, peptides that can inhibit these PPIs may be used as potential antiviral agents preventing virus entry and spread. This review is focused on peptides and peptidomimetics as PPI modulators and protease inhibitors against SARS-CoV-2.
严重急性呼吸综合征冠状病毒2(SARS-CoV-2)引发的新冠疫情在全球范围内导致了高发病率和死亡率。可以通过多种策略来阻断病毒进入细胞,包括抑制病毒刺突糖蛋白与细胞受体之间的蛋白质-蛋白质相互作用(PPI),以及阻断刺突蛋白在裂解/激活和融合能力方面所需的构象变化。刺突介导的病毒通过病毒包膜与细胞膜融合而附着并进入细胞,这涉及由具有特定二级结构的短肽片段介导的PPI。因此,能够抑制这些PPI的肽可作为潜在的抗病毒药物来阻止病毒的进入和传播。本综述聚焦于作为PPI调节剂和针对SARS-CoV-2的蛋白酶抑制剂的肽和肽模拟物。
