Five derivatives 3-(1, 3- substituted diphenyl-1H-pyrazole-4-yl-) propionic acidswere synthesized by reduction of 3-(1,3-diphenyl-1H-pyrazole-4-yl-) acrylic acid in ethyl acetate was added in the presence of 20% palladium / charcoal with constant stirring. The reaction mixture was stirred for overnight and the excess of ethyl acetate was distilled off under reduced pressure. The precipitate obtained was filtered, dried and recrystallized from appropriate solventThe chemical structures of these compounds were confirmed by means of Physical data and IR spectral data. The compounds were assayed for antiinflammatory activity.Among the compounds 4a and 4d showed significant anti-inflammatory activity, 4b and 4e showed moderate anti- inflammatory activity
