Detailed interactions between favipiravir ribofuranosyl-5′-triphosphate (F-RTP) and the active sites (red-colored regions) of (a) influenza H3N2 PB1 protein, (b) influenza H1N1 PB1 protein, (c) severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) RNA-dependent RNA polymerases (RdRp), (d) SARS-CoV RdRp, and (e) Middle East respiratory syndrome coronavirus (MERS-CoV) RdRp. Three-dimensional configurations of F-RTP and proteins were constructed with space-filling or stick models.
