There does seem to be some protease inhibition involved. An in silico data analysis conducted by Choudhury et al. demonstrated that ivermectin efficiently utilizes viral spike protein, main protease, replicase, and human TMPRSS2 receptors as the most possible targets for executing its "antiviral efficiency" by disrupting binding.[1] [1] https://www.nature.com/articles/s41429-021-00491-6 https://www.nature.com/articles/s41429-021-00491-6
