nsp12-in-2

Nsp12-IN-2 (Compound 8), a triphosphate metabolite of 4'-thiouridine, functions as an inhibitor of SARS-CoV-2 Nsp12. It effectively suppresses the RNA-dependent RNA polymerase (RdRp) activity of the SARS-CoV-2 Nsp12-Nsp7-Nsp8 complex, halting RNA synthesis and blocking the RNA capping and NMP capping of Nsp9. Nsp12-IN-2 shows potential for research into infections caused by SARS-CoV-2, other coronaviruses, and additional RNA viruses.

13-TP is an inhibitor of SARS-CoV-2. It effectively suppresses in vitro RNA synthesis catalyzed by the central replication-transcription complex (C-RTC, nsp12-nsp7-nsp82) of SARS-CoV-2. 13-TP fully inhibits RdRp polymerase activity and obstructs the complete extension of some primer RNAs.

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.
