Application

2-Mercaptopyridine N-oxide can be used to generate bidentate oxothiolane chelates with transition metals.
2-Mercaptopyridine N-oxide, also called pyrithione, is added to cells in culture so metals enter them readily without relying on transporters. It is used to study picornavirus infections.

Biochem/physiol Actions

2-Mercaptopyridine N-oxide is a zinc ionophore that transports zinc into cells.

We have discovered two metal ion binding compounds, pyrithione (PT) and hinokitiol (HK), that efficiently inhibit human rhinovirus, coxsackievirus, and mengovirus multiplication. Early stages of virus infection are unaffected by these compounds. However, the cleavage of the cellular eukaryotic translation
