Abstract
Influenza viruses pose a significant threat to global public health, and traditional antiviral drugs face challenges such as drug resistance. This study aims to investigate the mechanisms of novel antiviral drugs against influenza viruses, providing theoretical evidence for the development of more effective anti-influenza drugs. By establishing various influenza virus infection models at both cellular and animal levels, high-throughput screening technology was employed to identify potential antiviral compounds from large compound libraries. Further investigation using interdisciplinary approaches, including molecular biology, biochemistry, and structural biology, elucidated the interaction between these drugs and key viral targets such as neuraminidase and RNA polymerase, as well as their inhibitory mechanisms. Results demonstrated that the novel antiviral drugs specifically bind to critical targets on the influenza virus, effectively blocking the viral replication cycle. These drugs exhibited excellent antiviral efficacy in both cellular and animal models, showing higher efficiency in reducing viral load compared to traditional drugs and potentially decreasing the risk of drug resistance in viral variants. This study not only reveals the unique mechanisms of novel antiviral drugs against influenza but also provides new insights into designing next-generation antiviral drugs with high efficacy and low toxicity. The innovation lies in the first clear identification of specific binding modes between these drugs and viral targets, as well as their unique pathways of inhibition, opening new directions for antiviral drug research.
