Background: Nitazoxanide (NTZ), a broad-spectrum antiviral undergoing clinical development for treating influenza, COVID-19 and other viral respiratory illnesses, is a mild uncoupler of oxidative phosphorylation.
Methods: We evaluated the effect of Tizoxanide (TIZ), the active circulating metabolite of NTZ, on Adenosine Triphosphate (ATP) and cell viability in Madin-Darby Canine Kidney (MDCK) cells and in MDCK cells infected with influenza A and B viruses.
Results: TIZ decreased cellular ATP in a dose-dependent manner in MDCK cells and in MDCK cells infected with influenza A and B viruses. Maximum inhibition of ATP in influenza-infected or uninfected MDCK cells reached up to 45% after 6 and 24 hours of exposure to 100 μM TIZ. The decrease in cellular ATP did not affect cell viability and was reversible after eli.. View More»
