The synthesis and pharmacological properties of a novel type of [(arylpiperazinyl)alkoxy]anilines with dopaminergic properties are described. One of these compounds, 3-[3-(4-phenyl-1-piperazinyl)propoxy]benzenamine (4c), has been identified as a selective dopamine (DA) autoreceptor agonist in tests that include [3H]haloperidol binding, inhibition of striatal DA synthesis, inhibition of DA neuronal firing, inhibition of spontaneous locomotor activity, and reversal of reserpine-induced depression in rats. In addition, 4c possesses good oral activity in the Sidman conditioned avoidance test in squirrel monkeys, which is indicative of antipsychotic activity. In a primate model, 4c was found to lack the liability for extrapyramidal side effects usually associated with antipsychotic drugs.

D014150 Antipsychotic Agents Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus.
