This present study was undertaken to synthesize and investigate possible analgesic activities of some 2-(2-carboxyphenylsulfanyl)-N-(4-substitutedphenyl)acetamide derivatives that were designed by combining an analgesic drug thiosalicylic acid and the main pharmacophore group of paracetamol, N-(4-substitutedphenylacetamide). Chemical structures of synthesized compounds were elucidated by IR, H-1-NMR, and Mass spectral data. Paracetamol, thiosalicylic acid and some of the synthesized compounds in the series exhibited significant analgesic activities in hot-plate, tail-clip, and acetic acid-induced writhing tests. Compound 2d showed more potent analgesic activity than both paracetamol and thiosalicylic acid. None of the compounds changed the responses of animals recorded in Rota-Rod or activity cage tests with respect to control values. Therefore, analgesic activities of the synthesized compounds evaluated in this study were not caused by motor impairments or neurosedative effects.
