Eleven-membered heterocycles (dibenz[g,j]-1-oxa-4-azacycloundecenes) and open-chain analogues were synthesized and investigated for affinities to human dopamine receptor subtypes. The moderately rigidized rings displayed nanomolar and subnanomolar Ki values at D1-like receptors with a significant D1 to D2 and a slight D5 to D 1 selectivity. The open-chain analogues showed lower affinities but significant D1 to D2 selectivities. Compound 3 (K i(D5) = 0.57 nmol) showed antagonistic or inverse agonistic binding characteristics in a functional Ca assay.
