The aim of the present study was to evaluate the antinociceptive effect of the novel pyrazoline methyl ester: 4-methyl-5-trifluoromethyl-5-hydroxy-4,5-dihydro-1H-pyrazole methyl ester (MPF4). ⋯ The results of the present study suggest that MPF4 represents a potential target for the development of new drugs to treat persistent inflammatory pain.
