DESCRIPTION

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.
