A number of DATS have been studied for agonist activity with dopamine (DA) and beta (beta) type adenylate cyclases and the most potent ones were found among the 6,7-DATs and the 5,6-DATs, respectively. None of the compounds tested possessed antagonist activity. The observed activities were not expected on the basis of structural analysis of model compounds such as apomorphine and 6,7-dihydroxy-1-benzyltetrahydroisoquinoline. A new view was constructed which suggests that the nitrogens of the DAT compounds were positioned better than those of the model compounds with regard to their binding sites.
