Nitazoxanide controls virus viability through its impact on membrane bioenergetics.

ABSTRACT: Viruses are dependent on cellular energy metabolism for their replication, and the drug nitazoxanide (Alinia) was shown to interfere with both processes. Nitazoxanide is an uncoupler of mitochondrial oxidative phosphorylation (OXPHOS). Our hypothesis was that mitochondrial uncoupling underlies the antiviral effects of nitazoxanide. Tizoxanide (the active metabolite of nitazoxanide), its derivative RM4848 and the uncoupler CCCP were applied to a virus-releasing cell line to obtain the same increasing levels of mitochondrial uncoupling, hence identical impact on OXPHOS. A decrease in infectious viral particle release was observed and reflected the intensity of impact on OXPHOS, irrespective of the nature of the drug. The antiviral effect was significant although the impact on OXPHOS was mode
