Inhibition of 3CL protease activity. PMRwater and PMREtOH inhibited the activity of 3CL protease of SARS-CoV-2 in a dose-dependent manner. A control inhibitor, GC-376 (500 μM), was used as a positive control. The inhibition percentage was determined according to the optical density normalized to the 3CL protease activity without extract. The data represent mean ± SD (
