title: [3H] 2-Amino-6,7-dihydroxy 1,2,3,4-tetrahydronapthalene (ADTN): a potential specific dopamine receptor ligand.
abstract: The characteristics of [3H] 2-amino-6,7-dihydroxy 1,2,3,4-tetrahydronapthalene (ADTN) binding to calf striatal membranes were investigated. [3H]ADTN was observed to bind with high affinity and stereospecificity to a preparation of crude synaptic membranes. A number of dopamine agonists and antagonists were studied for their ability to displace bound [3H]ADTN. Dopamine agonists were found to be more potent inhibitors of ADTN binding than were dopamine antagonists. Kinetic analysis indicates that [3H]ADTN binds to dopamine recognition sites in a manner comparable to dopamine itself. Overall, the data suggest that ADTN may be a useful ligand for the characterization of agonist requirements for recognition by dopamine binding sites.
