Repurposing Vancomycin as a Potential Antiviral Agent Against PEDV via nsp13 Helicase Inhibition.

ABSTRACT: Porcine epidemic diarrhea virus (PEDV) causes a highly contagious intestinal disease with severe economic impacts on the global swine industry. The non-structural protein 13 (nsp13), a viral helicase, is essential for viral replication, making it a promising target for antiviral drug development. In this study, through virtual screening and molecular dynamics simulations, Vancomycin, a small-molecule drug also clinically used as an antibacterial agent, was identified to exhibit a stable binding affinity for PEDV nsp13. The NTPase and ATP-dependent RNA helicase activities of PEDV nsp13 were confirmed in vitro, and the optimal biochemical reaction conditions for its dsRNA unwinding activity were established. Further experiments demonstrated that Vancomycin effectively inhibited the du
