- Claim: 6. A radiolabeled amine compound in accordance with claim 1 wherein the hydrocarbyl amino group comprises an arylsulfonamido group.
- Claim: 7. A radiolabeled amine compound in accordance with claim 6 wherein the arylsulfonamido group has the general formula: ##STR6## where Ar comprises aryl group selected from phenyl and naphthyl.
- Claim: 8. A radiolabeled amine compound in accordance with claim 7 wherein Ar is substituted with a dimethylamino group.
- Claim: 9. A radiolabeled amine compound in accordance with claims 4, 5 or 6 wherein X is lower alkylene containing 1 to about 6 carbon atoms.
- Claim: 10. A radiolabeled amine compound in accordance with claim 9 wherein the lower alkylene group is selected from the group consisting of methylene, ethylene and trimethylene.
- Claim: 11. A radiolabeled amine compound of the general formula
- Claim: wherein X is selected from the group consisting of oxygen, sulfur, lower alkylene, radioactive selenium and radioactive tellurium, and where, if X is radioactive selenium or tellurium, Y is an arylamino group selected from the group consisting of a benzenesulfonamido-, naphthalenesulfonamido-, dibenzylamino-, bis(phenylethyl)amino- and benzyhdrylamino group, or where, if X is oxygen, sulphur, or lower alkylene, Y is a radioactive iodine-substituted arylamino group selected from benzenesulfonamido-, naphthalenesulfonamido-, dibenzylamino-, bis(phenylethyl)amino- and benzhydrylamino-; or a pharmaceutically-acceptable, acid salt of said amine compound.
- Claim: 12. A radiolabeled amine compound in accordance with claim 11 wherein the arylamino group is substituted by one or more substituent groups selected from the group consisting of halogen, nitro, cyano, hydroxy and carbon containing groups of up to about 6 carbon atoms.
- Claim: 13. A radiolabeled amine compound in accordance with claim 12 wherein the substituent group is a carbon-containing group selected from the group consisting of alkyl, alkoxy, alkanoyl, aminoalkyl, monoalkylamino, dialkylamino, carboxy and alkoxycarbonyl.
- Claim: 14. A radiolabeled amine compound in accordance with claim 11 wherein X is selected from oxygen, sulphur, lower alkylene and Y is an arylamino selected from a benzenesulfonamido-, naphthalenesulfonamido-, dibenzylamino, bis(phenylethyl)amino or benzhydrylamino- group which is substituted with radioactive iodine.
