Ten top virtual screening hits for Mpro as reported in Table S51. of an article "A multi-pronged approach targeting SARS-CoV-2 proteins using ultra-large virtual screening" by Gorgulla et al. (iScience 24, 102021, https://doi.org/10.1016/j.isci.2020.102021). Authors used "ultra-large-scale in silico screening platform, VirtualFlow, to search for inhibitors that target SARS-CoV-2". They screened roughly 1 billion molecules against targets including MPro. In Fig. S13 they show the predicted binding mode of their top compound which is very different compared to our leads: there is no direct interaction with His163. It might be interesting to check it out.
