ABSTRACT:
A series of adenosine-5'-uronamide derivatives bearing N.sup.6 -arylurea, alkarylurea, heteroarylurea, arylcarbonyl, alkarylcarbonyl or heteroarylcarbonyl groups which have affinity and, in some cases, selectivity for the adenosine A.sub.1 or A.sub.3 receptors are disclosed. These compounds can be used in a pharmaceutical composition to treat disorders caused by excessive activation of the A.sub.1 or A.sub.3 receptors, or can be used in a diagnostic application to determine the relative binding of other compounds to the A.sub.1 or A.sub.3 receptors.
