Nonsteroidal Anti-inflammatory Drug-based<i>N</i>-Allylidene Benzohydrazides and 1-Acyl-2-pyrazolines: Their Synthesis as Potential Cytotoxic Agents<i>In Vitro</i>
1‐acyl‐2‐pyrazoline derivatives derived from nonsteroidal anti‐inflammatory drugs was designed as potential anticancer agents. Synthesis of these compounds was carried out via the condensation reaction of chalcones and acid hydrazides under heating. The methodology did not require the use of any costly reagents or catalysts, and the acid hydrazide reactants were readily prepared from mefenamic acid or
