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 R-1 is H or a small substituent and R-2 = H, with D1 binding affinity and adenylate cyclase functional potency equivalent to that of A-86929(2a).
