title: trans-2,6-,3,6- and 4,6-diaza-5,6,6a,7,8,12b-hexahydro-benzo[c]phenanthrene-10,11- diols as dopamine agonists.
abstract: The title compounds were synthesized by replacing the thiophene moiety of A-86929(2a) with variously substituted pyridines. Dopamine D-1 and D-2 binding and adenylate cyclase assays indicate that 4,6-diaza compounds 15 are potent and selective full D1 agonists when R1 is H or a small substituent and R2 = H, with D1 binding affinity and adenylate cyclase functional potency equivalent to that of A-86929(2a).
