摘要

Polyphenols are a diverse group of naturally occurring bioactive compounds in plants that have attracted considerable interest due to their potential antiviral properties. Polyphenols primarily exert their antiviral effect by specifically targeting the viral replication. This review examines the role of polyphenols as potential antiviral agents with a focus on their structure, mechanism of action, and bioavailability. Different polyphenols, their origin, and documented effects on viral pathogens that impact the health of finfish are also discussed. The focus has been on the experimental studies conducted on the antiviral activity of polyphenols against fish viruses. Various studies on polyphenols such as such as flavanols, flavonoids, and phenolic acids have revealed their potential antiviral properties in aquaculture, whereas some polyphenolic compounds also exhibit anti-cancer, neuroprotective, and anti-inflammatory properties. Studies on polyphenolic compounds like coumarin and its derivatives have shown potential antiviral effect against OIE-reported fish viruses like IHNV, VHSV, and SVCV. However, there still remains a critical gap in understanding and exploring the long-term impact of polyphenols on fish health and their effectiveness as potent antiviral agents. Targeted research on these compounds will allow for the development of effective antiviral strategies in aquaculture. Thus, continuous exploration of these natural antiviral agents holds a great potential for enhancing the health status of fishes in aquaculture.
