Porcine epidemic diarrhea virus (PEDV) causes high mortality in pigs. PEDV main protease (M pro ) plays an essential role in viral replication. We solved the structure of PEDV M pro complexed with peptidomimetic inhibitor N3 carrying a Michael acceptor warhead, revealing atomic level interactions. We further designed a series of 17 inhibitors with altered side groups. Inhibitors M2 and M17 demonstrated enhanced specificity against PEDV M pro . These compounds have potential as future therapeutics to combat PEDV infection.
