Ngai et al. reported ADS‐J1 (5; Figure 4) as a potential SARS‐CoV‐1 viral entry inhibitor with an EC50 of 3.89 µM. Molecular docking studies predicted that 5 can bind into a deep pocket of the SARS‐CoV‐1 S HR region and block viral entry into host cells. 51  Imatinib (6; Figure 4), an Abelson kinase inhibitor, could inhibit CoV S protein‐induced fusion with an EC50 value of 10 µM and showed no cytotoxic effects in Vero cells up to 100 µM concentration. 52 ,  53
