Structures of selected antiviral drugs that have therapeutic potential against SARS-CoV-2. Baricitinib, umifenovir and camostat mesylate are fusion inhibitors while lopinavir darunavir and atazanavir are protease inhibitors. Reverse transcription inhibitors such as remdesivir, favipiravir (Avigan) and ribavirin, neuraminidase inhibitors such as oseltamivir and M2 ion-channel protein blockers (amantadine) are potential against SARS-CoV-2.
