MECHANISMS OF ANTIVIRAL ACTIVITY OF FLAVONOIDS

Abstract

The article examines the multifaceted mechanisms underlying the antiviral activity of flavonoids, compounds widely distributed in the plant kingdom. The aim of the work was to review literature data on mechanisms of antiviral activity of flavonoids. Methods. Publications were selected based on the PubMed (https://pubmed.ncbi.nlm.nih.gov/) databases published in 2015–2023. They include information on mechanisms of antiviral activity of flavonoids. Results. Beginning with an overview of flavonoid structures, the document navigates through the intricate interactions between flavonoids and various stages of the viral life cycle. Drawing upon a comprehensive analysis of in vitro and in vivo studies, the review highlights the diverse ways in which flavonoids inhibit viral entry, replication, and release. Depending on their antiviral mechanisms, flavonoids can serve as preventive inhibitors, therapeutic inhibitors, or indirect inhibitors by influencing the immune system. Conclusion. The synthesized information not only contributes to the advancement of antiviral research but also lays the foundation for the development of novel therapeutic interventions against a spectrum of viral infections.
