Indeed, antiviral peptides have shown potential in inhibiting viral attachment and have even been reported to prevent SARS-CoV-2 infection, with some designed to directly target the receptor-binding domain (RBD) of the S protein2024年10月10日—Antiviral peptides (AVPs) aresmall molecules that inhibit the replication of viruses in living cells. AVPs are being investigated as potential ....

Furthermore, research into antimicrobial peptides has revealed that some possess significant antiviral activity against a wide range of human DNA and RNA viruses, playing an effective role in the treatment of viral diseases8: Peptides as Antiviral Drugs. These antiviral peptides can exert their effects through various mechanisms of action, targeting different stages of the viral replication cycleBetter understanding and prediction of antiviral peptides .... For example, P9R, a positively charged peptide, has been identified that binds to viruses and inhibits virus-host endosomal acidification – a vital process for viral replication and infection.

The development of peptide-based antiviral coatings is another exciting area of research. Peptide spherical assemblies have been shown to adhere to surfaces and form an antiviral coating against both RNA- and DNA-based viruses, including coronaviruses. This approach offers a novel strategy for preventing viral transmission and infection.

The field of peptide antiviral research is also being revolutionized by advancements in artificial intelligence (AI). AI-driven design is enabling the creation of next-generation antiviral peptides with enhanced potency and stability. Tools like Datt-AVP, which uses a dual-channel deep learning model, are helping to predict and identify novel antiviral peptides based on their sequences, accelerating the discovery process作者：MT Aziz·2025·被引用次数：1—Antiviral peptides(AVPs), produced by all living organisms, play a vital role as the first line of immune defense against viral infections..
