摘要： Swine Alpha-coronaviruses are one of the most destructive pathogens affecting the swine industries across the world. Swine Alpha-coronaviruses include transmissible gastroenteritis virus (TGEV), porcine epidemic diarrhea virus, porcine respiratory coronavirus, and swine acute diarrhea syndrome coronavirus (SADS-CoV). Thus far, swine Alpha-coronaviruses treatment options are very limited. Therefore, the identification of safe and effective treatment of swine Alpha-coronaviruses is urgently needed. In the current study, we screened a library of 240 FDA-approved compounds for antiviral activity against TGEV. Among screening, the 3CL protease inhibitor PF-00835231 was shown to dramatically inhibit TGEV replication in vitro systems. Mechanistically, PF-00835231 inhibits nonstructural protein 5 (Nsp5) protease activity targeting the cleavage at Nsp5-Nsp6 of TGEV. Additionally, PF-00835231 exhibited the potent broad-spectrum swine Alpha-coronaviruses antiviral activity. Treatment of PF-00835231 in mice not only blocks SADS-CoV deadly infection but also dramatically reduces viral copies. Taken together, our study provides evidence that PF-00835231 may control of the current swine Alpha-coronaviruses and emerging swine Alpha-coronaviruses in the future.
