anti-inflammatory-peptide-market Antiviral peptides (AVPs) are emerging as a significant class of therapeutics with the potential to combat a wide range of viral infectionsDRAVP: A Comprehensive Database of Antiviral Peptides .... These short chains of amino acids, essentially smaller versions of proteins, are garnering attention due to their potent activity, low cytotoxicity, and ability to overcome drug resistance. AVPs can exert both preventative and therapeutic functions, acting through diverse mechanisms such as destabilizing viral membrane envelopes, inhibiting viral attachment and entry into host cells, and preventing essential viral processes like endosomal acidification. Their broad-spectrum effects and potential for broad application make them a promising area of research and development in the fight against infectious diseases.
The efficacy of antiviral peptides stems from their multifaceted mechanisms of action, which can target various stages of the viral life cycle. A primary mode of action involves the direct perturbation of viral membranes. AVPs, particularly those that are polycationic, can interact with and disrupt the lipid bilayer of enveloped viruses, leading to virion inactivation作者：L Lu·2021·被引用次数：150—A series of peptides targeting viral TmS, espe- cially MPER and CT,can effectively inactivate virionsby disrupt- ing the membrane's integrity, ....

Beyond membrane disruption, AVPs can also interfere with the initial stages of viral invasion. They have demonstrated the ability to inhibit viral attachment to host cells by binding to viral surface proteins or host cell receptors, thereby blocking the virus's ability to dock and initiate infection. Furthermore, some AVPs can prevent viral entry by inhibiting the fusion of the viral membrane with the host cell membrane or by interfering with the process of endosomal acidification, a critical step for the release of viral genetic material into the cytoplasm. These diverse strategies highlight the versatility of AVPs as antiviral agents.
The development of antiviral peptides represents a significant advancement in therapeutic strategies against viral diseases.Viruses traverse the human proteome through peptide interfaces ... - PNAS Their emergence as "next-generation therapeutics" is driven by several key advantages over traditional antiviral drugs. AVPs often display broad-spectrum activity, meaning they can be effective against a wide range of viruses, including DNA and RNA virusesAI4AVP: an antiviral peptides predictor in deep learning .... This broad applicability is particularly valuable in situations where novel or rapidly evolving viruses pose a threat, such as during pandemics.From Molecular Mechanisms to Clinical Translation
Moreover, AVPs have shown a favorable safety profile with low cytotoxicity, meaning they are less likely to harm host cells. This is a critical consideration for any therapeutic agent. The ability of peptides to overcome drug resistance is another significant advantage, as many viruses develop resistance to conventional antiviral medications. AVPs offer a potential solution to this growing challenge. Research has explored various sources and designs for AVPs, including those derived from plants, marine organisms, and synthetic approaches, all aiming to harness their therapeutic potential. Databases dedicated to antiviral peptides, such as DRAVP, are being developed to aid in their identification and validation.作者：LCPV Boas·2019·被引用次数：355—This review aims to shed some light onantimicrobial peptides with antiviral activitiesagainst human viruses and update the data about the already well-known ...
Despite their immense promise, the development and application of antiviral peptides are not without their challenges.From Molecular Mechanisms to Clinical Translation A significant hurdle for peptide-based drugs, including AVPs, is their generally short half-life in vivo and poor oral bioavailability. This means they can be quickly degraded in the body and are not easily absorbed when taken orally, often necessitating alternative delivery methods like injection.
Overcoming these pharmacokinetic limitations is a key focus of ongoing research作者：J Guan·2024·被引用次数：27—Antiviral peptides (AVPs)have shown potential in inhibiting viral attachment, preventing viral fusion with host cells and disrupting viral .... Strategies such as chemical modifications, conjugation with other molecules (like CPPs – cell-penetrating peptides), and the development of novel delivery systems are being investigated to improve their stability and efficacy. The use of computational frameworks and artificial intelligence (AI) is also accelerating the discovery and design of new AVPs with enhanced properties. As research progresses, antiviral peptides are poised to play an increasingly vital role in the global effort to combat viral infections, offering a new avenue for effective and potentially resistance-breaking therapies.
