Scientists are increasingly exploring the potential of peptides as therapeutic agents and diagnostic tools, leveraging their unique properties to target the SARS-CoV-2 virus. This exploration spans various strategies, from direct inhibition of viral entry to the development of vaccines and diagnostic platforms.

One significant area of focus is the development of peptides that can inhibit the entry of SARS-CoV-2 into host cells.Small volumes ofCOVID-19 peptidevial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. The virus primarily enters cells by binding its spike protein to the host cell receptor, Angiotensin-Converting Enzyme 2 (ACE2). Researchers have engineered mimetic peptides of ACE2, such as the WT ACE2 peptide, which have demonstrated the ability to protect susceptible mice against in vivo SARS-CoV-2 infection. This approach aims to block the interaction between the viral spike protein and the host cell receptor. Similarly, MIT chemists have designed a peptide that can bind to part of the coronavirus spike protein, hoping to prevent the virus from entering cells. Studies have also explored peptide and peptide-based inhibitors of SARS-CoV-2 entry, summarizing strategies used to design peptides targeting the ACE2 receptor.

Beyond direct entry inhibition, peptide-based strategies against SARS-CoV-2 attack are being investigated for their therapeutic potential. For instance, CeSPIACE, a novel peptide drug, has been developed to offer broad protection against COVID-19 variants, including Omicron XBB作者：D Schütz·2020·被引用次数：215—Here, we summarize thecurrent status of peptides inhibiting SARS-CoV-2 entryand outline the strategies used to design peptides targeting the ACE2 receptor or ....1Peptide and peptide-based inhibitors of SARS-CoV-2 entry.5. This inhibitor peptide against the SARS-CoV-2 spike, engineered using a structure-guided strategy, exhibits mutation-tolerant and potent binding capabilities. Another promising development is the intranasal administration of broad-spectrum macrocyclic peptides, which has shown efficacy in preventing SARS-CoV-2 infection in mice. This method offers a non-invasive delivery route for potential therapeutics.
