There are no reports in the literature of dicoumerol having activity against SARS-CoV-2, just a single report predicting binding to M pro by Balakrishnan et al. . Fluspirilene activity against SARS-CoV-2 was reported by Weston et al. They measured the IC50 as 3.1µM, CC50 as 30.3µM and SI=10 in Vero E6 cells . This mirrors the activity of fluspirilene against MERS-CoV and SARS-CoV in Vero E6 cells of 7.5µM and 6.0µM, respectively . Doramapimod was reported to have an IC50 of 10µM against SARS-CoV-2 in MRC5-ACE2 cells, and showed synergism with remdesivir in killing the virus in vitro . Astemizole was reported to have an EC50 of 1µM SARS-CoV-2 in Vero E6 cells, together with EC50 values against MERS-CoV and SARS-CoV of 4.9µM and 5.5µM, respectively .
