A new series of Chalcones (2a-i) were prepared by Claisen-Schmidth Condensation reaction involving substituted aromatic aldehydes and aromatic ketones in alcohol medium, in presence of 40% NaOH as base. The title compounds Pyrazolines (3a-i) were synthesized by reacting Chalcones (2a-i) and 2-thiophene carbohydrazide (1) in glacial acetic acid medium. The final synthesized compounds were screened for their In-vitro anti-inflammatory activity by egg albumin denaturation method and protein denaturation method. The structures of the newly synthesized compounds were assigned on the basis of IR, 1H-NMR and Mass spectral data. The compounds 3b, 3c, 3d and 3f also showed good inhibition when compared to the standard diclofenac sodium
