Cocktailing Zn2+ ions with chloroquine might inhibit coronavirus to replicate and multiply
Increasing intercellular Zn2+ concentration can effectively impair the replication of variety of RNA viruses including poliovirus and influenza. The reason why the world has been discussing a lot about chloroquine, is its ability to act as a Zinc Ionophore. Chloroquine can enhance zinc uptake by cells, which in turn has be studied to have desired effects in stopping RNA replication for SARS-COV virus.
The inhibition effect created by Zn2+ ions in vitro demonstrates the ability of this cocktail therapy to substantially reduce the impact of COVID19 turning mild cases into severe ones. Chloroquine acts as a gateway for Zn2+ ions to get absorbed faster in cells for fast pacing this inhibition activity.
That said, there isn't any real trial results of this cocktail yet for the novel coronavirus. Zinc supplements have shown ability to inhibit growth of other 6 coronaviruses and rhinoviruses in past.
