In this work, synthesis of three pyrazoline derivatives (6-8) have been described. (E)-1,3-(phenylsubstituted)-prop-2-en-1-one (3-5) prepared by the reaction of substituted benzaldehyde with 4-methylacetophenone whereas condensation cyclization of the same chalcones (3-5) with phenylhydrazine hydrate in ethanol yielded 6-8. The structures of the title compounds (6-8) were characterized by chemical reactions, elemental analysis, and spectral methods such as IR spectra. The synthesized chalcone and pyrazolines were evaluated for in-vitro antibacterial and antioxidant activities against standard. The zone of inhibition for some of the newly synthesized compounds showed notable antibacterial activity against selected bacterial strains compared with ampicillin. Significant antioxidant activities were also shown by chalcone and pyrazolines.
