This invention relates to a diagnostic probe comprising a compound of formula (I):
such as 3-[2-[4-(5-aminopentyl-3-amidocarboxypropanoyl)]aminophenyl]ethyl]-8-benzyl-7-[2-ethyl(2-hydroxyethyl)amino]ethyl-1-propylxanthine, with one or more label moieties attached thereto. The compounds of the present invention are useful as diagnostic probes, including probes for diagnostic assays and imaging. Accordingly, the invention provides A
1
adenosine receptor antagonist compounds with radioactive or non-radioactive labels suitable for executing such assays and imaging measurements. Labeled compounds are useful to obtain quantitative measurements of the A
1
adenosine receptor antagonist compounds. They may be employed as an imaging agent in diagnostic procedures such as MRI and PET as well as cell or receptor based assays.
