[Image: see text] 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.
