Phencyclidine is an arylcyclohexylamine compound which has received a lot of investigative attention due to the complex spectrum of behaviours and its complicated interactions with the central nervous system. Phencyclidine administration may act as stimulant, depressant, hallucinogen, and analgesic depending on dose and tested species. In this study, new phenyl and thienyl analogues with specific affinity for the phencyclidine sites in NMDA receptors, dopamine uptake blocking, or both of them were synthesized. The acute and chronic pain properties of these compounds were studied using the tail immersion and formalin tests on mice and the results were compared with control and phencyclidine groups at a dose of 10 mg/kg. The outcomes indicated that all synthesized compounds showed better activities to decrease acute thermal and chemical, but not chronic pains. Also, these effects were more significant for phenyl (group 1) compared to thiophene (group 2) analogues, which is probably due to the higher affinity of group 1 for inhibition of dopamine reuptake compared to binding to the phencyclidine sites in NMDA receptors in this family.[GRAPHICS].
