Original Research


A series of acyl hydrazone derivatives were synthesized and screened for antiinflammatory and analgesic activities. The N-acylarylhydrazone compounds described herein were designed by combining the pharmacophoric features of hydrazones and styryl ketones in order to identify the pharmacophoric contribution of the N-acylarylhydrazone moiety and to study the structure–activity relationships. In carrageenan-induced paw edema test, N′-(4-hydroxy benzylidene)-2-acetamido-3-phenyl propenohydrazide (6j) reduced edema by 74 % which is comparable to the standard reference drug, phenylbutazone at equidose. N′-(4-methoxy benzylidene)-2-acetamido-3-phenyl propenohydrazide (6g) showed analgesic activity (68 %) which is equipotent to the standard drug, aspirin (64 %). Molecular docking studies further confirmed that 6j showed better binding affinity with COX-2 and LOX-5 with reduced gastric ulcerogenic effect when compared to phenylbutazone.
