[The antiviral targeting potential of viroporins]

Viroporins are ion channels found in many viruses, where they contribute to virus life cycle and thereby pathogenesis. Viroporin targeting is a known, yet largely unexplored, therapeutic strategy so far only used in Influenza A with the drugs amantadine and rimantadine. In this review, we seek to utilize the inhibition by amantadine of the viroporin Protein E in SARS-CoV-2 in an attempt to treat COVID-19 in its early stages. We are executing a double-blinded placebo-controlled trial based on promising in vivo and in vitro work as a stepping-stone for establishing a therapeutic antiviral regime: blocking of viroporins.
