SYNTHESIS, BIOLOGICAL EVALUATION AND MOLECULAR PROPERTIES PREDICTION OF 1, 3, 5-TRISUBSTITUTED 2-PYRAZOLINE DERIVATIVES

A number of trisubstituted 2-pyrazolines which are known for their biological importance like antimicrobial, anti-inflammatory, antitubercular, analgesic, anticancer, antimalarial, anti-viral, antihelmentic activities are prepared by reacting chalcones with phenyl hydrazine in absolute ethanol in presence of pyridine. In the present investigation an attempt has been made for the synthesis of 2-pyrazoline derivatives and subjected to molecular properties prediction by molinspiration, molsoft and osiris softwares. The synthesized compounds have been confirmed by IR, Mass and (HNMR)-H-1 spectral data. These compounds were also screened for various biological activities like antifungal, anti-inflammatory and acute toxicity activity by standard methods. The synthesized compounds have shown moderate to good antifungal, anti-inflammatory activity and some of the synthesized compounds have shown significant activity as compared with standard. Compound 5d showed good antiinflammatory activity, compounds 5c, 5d, and 5e showed higher antifungal activity and all the synthesized compounds were found to be in conformity with lipinski's rule.
