Antipsychotic profile of 5-[2-[4-(6-fluoro-1H-indole-3-yl)piperidin-1-yl]ethyl]-4-(4-fluorophenyl)thiazole-2-carboxylic acid amide (NRA0562) in rats.

The antipsychotic profile of 5-[2-[4-(6-fluoro-1H-indole-3-yl)piperidin-1-yl]ethyl]-4-(4-fluorophenyl)thiazole-2-carboxylic acid amide (NRA0562) was investigated using the conditioned avoidance test in rats. NRA0562 is a putative "atypical" antipsychotic agent with moderate to high affinities for dopamine D(1), D(2), D(4), 5-hydroxytryptamine(2A) receptors and alpha(1) adrenoceptor. NRA0562 (1 and 3 mg/kg, p.o.) dose-dependently and significantly impaired the conditioned avoidance response. Likewise other atypical antipsychotics such as risperidone (1 and 3 mg/kg, p.o.) and clozapine (100 mg/kg, p.o.) dose-dependently and significantly impaired the conditioned avoidance response in rats. In addition, typical antipsychotics, haloperidol (1 and 3 mg/kg, p.o.) potently impaired the conditioned avoidance response.These results suggest that antipsychotic profile of NRA0562 is consistent with profiles of clozapine or risperidone and may be considered an atypical antipsychotic agent.
