Abstract: Zn(II) is an inhibitor of SARS-CoV-20 s RNA-dependent RNA polymerase, and chloroquine
and hydroxychloroquine are Zn(II) ionophores–this statement gives a curious mind a lot to think
about. We show results of the first clinical trials on chloroquine (CQ) and hydroxychloroquine (HCQ)
in the treatment of COVID-19, as well as earlier reports on the anticoronaviral properties of these two
compounds and of Zn(II) itself. Other FDA-approved Zn(II) ionophores are given a decent amount of
attention and are thought of as possible COVID-19 therapeutics.
