Antimalarial drugs inhibit the replication of SARS-CoV-2: An in vitro evaluation
Small molecule In vitro
Vero E6 cells; SARS-CoV-2 IHUMI-3 strain 4.59

The antimalarial drug inhibited SARS-CoV-2 in vitro at IC50 and IC90 similar to the concentrations reached during oral antimalarial treatment.

Quinine Inhibits Infection of Human Cell Lines with SARS-CoV-2
Small molecule In vitro
Vero B4 cells; Caco-2 cells; Calu-3 cells; TMPRSS2 and/or ACE2-expressing A549 cells 5.05

Exerts antiviral activity against SARS-CoV-2 as tested on TMPRSS2-positive human cancer cell lines. It displays lower toxicity compared to chloroquine or hydroxychloroquine. Depending on the cell line used, the observed IC50 was in the range of ca. 3.7 to 50 μM.
