Ferrocin A is a lipopeptide compound that targets the SARS-CoV-2 RNA-dependent RNA polymerase (nsp12). It binds stably to nsp12 and, by chelating iron, reduces the concentration of free iron in the environment. This action inhibits bacterial growth by preventing the acquisition of essential metal cations. As an iron-chelating antiviral agent, Ferrocin A is applicable for research in COVID-19 and bacterial infections.
