Diagnostic agent for hypoxia or mitochondrial dysfunction

摘要

The present invention relates to a diagnostic agent for hypoxia or mitochondrial dysfunction comprising: (a) a radioactive copper complex of a dithiosemicarbazone derivative or a radioactive copper complex of a diamine diol schiff base derivative as defined in claim 1; and (b) a pharmaceutically acceptable diluent or carrier. The diagnostic agent according to the present invention has a good transferability to the target tissue, reduction reaction affinity at a hypoxic site, high stability in a non-target site and rapid disappearance ability therefrom.
