Dopamine/Serotonin Receptor Ligands. 9. Oxygen-Containing Midsized Heterocyclic Ring Systems and Nonrigidized Analogues. A Step toward Dopamine D5 Receptor Selectivity
摘要:
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 sulmanomolar K-i values at D-1-like receptors with a significant D-1 to D-2 and a slight D-5 to D-6 selectivity. The open-chain analogues showed lower affinities but significant D-1 to D-2 selectivities. Compound 3 (K-i(D-5) = 0.57 nmol) showed antagonistic or inverse agonistic binding characteristics in a functional Ca assay.
