An unidentified metabolite of dimetridazole (DMZ), found in pig plasma, muscle and kidney, was shown by chromatography and spectroscopy to be 2-methyl-5-nitroimidazole (2-MNI), resulting from N-demethylation of DMZ. This route of degradation competes with the oxidation pathway previously described. The

The inflammation- and infection-seeking properties of (131)I-labeled ornidazole, a 5-nitroimidazole derivative, have recently been reported. Whole-body images in rabbits showed a more rapid uptake in inflamed areas compared to (67)Ga. In the present study, two novel (123)I-labeled 2-methyl-4-nitroimidazole derivatives were
