Abstract:

A series of structurally novel compounds possessing 2-phenylpiperazin-1-yl nicotinamide template was synthesized and evaluated for neuropathic pain activity. After the assessment of neurotoxicity and peripheral analgesic activity, the compounds were evaluated in a peripheral neuropathic pain model, the chronic constriction injury (CCI) to assess their antiallodynic and antihyperalgesic potential. Studies carried out to assess the underlying mechanism revealed that the compounds (5 and 6) suppressed the inflammatory component of the neuropathic pain and inhibited oxidative and nitrosative stress.

Keywords: Neuropathic pain, antiallodynic, antihyperalgesic, carrageenan, nitric oxide, DPPH
