SARS-CoV-2 has raised the alarm to search for effective therapy for this virus. To date several vaccines have been approved, but few available drugs reported recently still need approval from FDA. Antiviral compositions having niclosamide derivatives were prepared for treating COVID-19. Using a FRET-based enzymatic assay, three niclosamide derivatives, JMX0286, JMX0301, and JMX0941, were identified as potent allosteric inhibitors against SARS-CoV-2 3CLpro, with IC50 values similar to that of known covalent inhibitor boceprevir. In a cell-based antiviral assay, these inhibitors can inhibit the virus growth with EC50 in the range of 2-3 μM. The mechanism of action of JMX0286, JMX0301, and JMX0941 were characterized by enzyme kinetics, affinity binding and protein-based substrate digestion. Molecular docking suggested that JMX0286, JMX0301, and JMX0941 bind specifically to an allosteric pocket of the SARS-CoV-2 3CL protease.
