Abstract

A new series of Chalcones (2a-j) were prepared by reacting 2-acetyl Pyrrole and substituted ketones in alcohol medium in presence of NaOH. The Chalcones undergoes selective cyclization with phenoxy acetic acid hydrazide (1) in glacial acetic acid medium to yield the title compounds 1,3,5-trisubstituted Pyrazolines (3a-j). The newly synthesized compounds were evaluated for their In-vitro anti-inflammatory activity by egg albumin denaturation and protein denaturation method. All the new compounds were established on the basis of 1H-NMR, IR and Mass spectral data. Some of the tested compounds 3a, 3f showed good anti-inflammatory activity when compared to the standard drug diclofenac sodium.
