Disclosed are compounds of the formula: wherein R1 represents optionally substituted aryl, heteroaryl, arylalkyl, or cycloalkyl groups; X, Z, and Y are optionally substituted nitrogen or carbon atoms; R3 and R4 are organic or inorganic substitutents which may togther form ring structutes; m is zero, one or two; and R5 and R6 are are organic or inorganic substituents; and the pharmaceutically acceptable addition salts thereof, which compounds are highly selective partial agonists or antagonists at brain dopamine receptor subtypes or prodrugs thereof and are useful in the diagnosis and treatment of affective disorders such as schizophrenia and depression as well as certain movement disorders such as Parkinsonism.
Synthesis of 2-(2,3-dimethoxyphenyl)-4-(aminomethyl)imidazole analogues and their binding affinities for dopamine D2 and D3 receptors

A series of 2-(2,3-dimethoxyphenyl)-4-(aminomethyl)imidazole derivatives was prepared and their affinity for dopamine D2 and D3 receptors was measured using in vitro binding assays. Several oxadiazole analogues were also prepared and tested for their affinity for dopamine D2 and D3 receptors. The results of receptor binding studies indicated that the incorporation of an imidazole moiety between the phenyl ring and the basic nitrogen did not significantly increase the selectivity for dopamine D3 receptors, whereas the incorporation of an oxadiazole at the same region resulted in a total loss of affinity for both dopamine receptor subtype binding sites. The most selective compound in this series is 2-(5-bromo-2,3-dimethoxyphenyl)-4-(6,7-dimethoxy-1,2,3, 4-tetrahydroisoquinolinomethyl)imidazole (5i), which has a D3 receptor affinity of 21 nM and a 7-fold selectivity for D3 versus D2 receptors. The binding affinity for σ1 and σ2 receptors was also measured, and the results showed that several analogues were selective σ1 receptor ligands.

A series of 2-phenyl-4-(aminomethyl)imidazoles were designed as conformationally restricted analogs of the dopamine D2 selective benzamide antipsychotics.The title compounds were synthesized and tested for blockade of YM-09151 binding in cloned African green monkey dopamine D2 receptor preparations.The binding affinity data thus obtained were compared against that of the benzamides and a previously described series of 2-phenyl-5-(aminomethyl)pyrroles.
