General description
2-Mercaptopyridine N-oxide forms complexes on reaction with palladium chloride. It inhibits NADH-fumarate reductase purified from Trypanosoma cruzi. It is precursor to O-acyl thiohydroxamates. It ligates to metals to form biologically active complexes.
Application
2-Mercaptopyridine N-oxide was used to investigate the mechanism of photodegradation of mercaptopyridine-N-oxide biocides. It was used in ratiometric fluorescence imaging of intracellular zinc ions in mammalian cultures.
Precursor to O-acyl thiohydroxamates. Ligates to metals to form biologically active complexes.
