The intense research work in the field of medicinal chemistry has enhanced the significance of Biphenyl moiety as pharmacologically important compound. Some of the compounds bearing Biphenyl moiety possess important medicinal properties like antihypertensive and calcium channel blocker, anti-inflammatory, diuretic, anti-diabetic activity, antipsychotic and anxiolytic activity. The present article describes the synthesis of novel benzohydrazides and 2-phenylbenzohydrazides bearing Biphenyl moiety and vanillin hybrid. The synthesized compounds (31-40) were characterized by ¹H NMR, Mass and IR spectroscopic techniques and were evaluated for anti-inflammatory activity by carrageenan paw edema method. The results of the study revealed that compounds 39 and 40 (bearing 2-phenylacetohydrazides) showed maximum anti-inflammatory activity while the compounds 31, 32, 33, 34 and 38 bearing benzohydrazides displayed moderate anti-inflammatory activity.
