General description

2-Mercaptopyridine N-oxide acts as labelling agent during indium-111 labelling of human platelets. It acts as bioactive ligand and forms palladium and platinum complexes, which were tested as potential antitrypanosomal agents.

Application

For chemistry of 2-mercaptopyridine-N-oxide, see Aldrichimica Acta.

Human platelets were labelled in the absence or presence of plasma using indium-111 labelled oxine sulphate, tropolone or 2-mercaptopyridine-N-oxide (MPO). Under in vitro and in vivo conditions, platelet functions were evaluated by measuring their aggregability, survival, recovery and early distribution.
