Because of the uninterrupted spread of novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infectious disease (COVID-19) with substantial illness and mortality rates, there is an urgent requirement of suitable antiviral agent/therapy to control this pandemic, but not yet established. The primary cause of SARS-CoV-2 infection is the crosstalk between the SARS-CoV-2 and host surface receptor protein, human angiotensin-converting enzyme 2 (hACE2), prior to cellular entry. Hence, blocking at the initial stage of virus entry could be a promising strategy/therapy to combat the SARS-CoV-2 infection. Many drugs as SARS-CoV-2 blocker have been proposed. Among them, peptide-based antivirals are one. This Viewpoint discusses the potential antiviral role and feasibility of two classes of peptides for prevention of SARS-CoV-2 infection, where (1) a designed peptide (replication of virus binding domain of hACE2), and (2) antimicrobial peptides (AMPs; natural and first line host defense peptide), both may reduce virus load into the host cell by blocking cellular surface receptors and/or disruption of virus cell membrane at the stage of virus entry. These finding may provide a novel antiviral therapy against COVID-19, which might control the current global health crisis.

基于肽的抗病毒疗法对抗 SARS-CoV-2 感染的潜在作用。

由于新型严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 传染病 (COVID-19) 的不间断传播,疾病和死亡率很高,迫切需要合适的抗病毒药物/疗法来控制这一流行病,但尚未建立。SARS-COV-2 感染的主要原因是 SARS-COV-2 在进入细胞之前与宿主表面受体蛋白、人血管紧张素转换酶 2 (hACE2) 之间的串扰。因此,在病毒进入的初始阶段进行阻断可能是对抗 SARS-CoV-2 感染的一种有前途的策略/疗法。已经提出了许多药物作为 SARS-CoV-2 阻断剂。其中,基于肽的抗病毒药物就是其中之一。本观点讨论了两类肽预防 SARS-CoV-2 感染的潜在抗病毒作用和可行性,其中 (1) 设计的肽(hACE2 病毒结合域的复制),以及 (2) 抗菌肽 (AMP;天然和一线宿主防御肽),两者都可以通过在病毒进入阶段阻断细胞表面受体和/或破坏病毒细胞膜来减少进入宿主细胞的病毒负荷。这些发现可能会提供一种针对 COVID-19 的新型抗病毒疗法,从而可能控制当前的全球健康危机。
