In Vitro	Mpro inhibitor N3 (0-100 µM) 具有抗病毒活性，对 SARS-CoV-2 的 EC50 值为 16.77 µM[1]。 Mpro inhibitor N3 (0-50 µM; 14 h) 抑制病毒生长，对 HCoV-229E、FIPV 和 MHV-A59 的 IC50 值分别为 4、8.8、2.7 µM[2]。
In Vivo	Mpro inhibitor N3 (0-0.64 µM; 3, 6 h) 在鸡胚胎中表现出抗 IBV 的抗病毒活性[3]。 Animal Model: Chicken embryos[3] Dosage: 0-0.64 µM Administration: 3, 6 h with 100-EID50 titer of IBV M41 virus Result: Showed that N3 is able to penetrate cells to inhibit the replication of IBV viruses, probably at the beginning of infection, with the PD50 of 0.13 μmol for the 3-h group and 0.17 μmol for the 6-h group.
