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.

In the search for new therapeutic tools against Chagas disease (American trypanosomiasis) palladium and platinum complexes of the bioactive ligand pyridine-2-thiol N-oxide were exhaustively characterized and evaluated in vitro. Both complexes showed high in vitro growth inhibition activity (IC(50) values
