Environment Friendly Synthesis of N′-(1,3-Diphenylallylidene)-1-ethyl-7-methyl-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carbohydrazides: Crystal Structure and Their Anti-oxidant Potential

Abstract

An environment friendly synthesis of novel hybrid pharmacophores derived from synergism of nalidixic acid and 1,3-diphenylprop-2-en-1-ones is described. Percent yield and reaction times of microwave assisted reactions have been compared with the reactions carried out under conventional reaction conditions which show marked decrease in reaction times and significant increase in yields. Besides, anti-oxidant potential of the synthesized hybrid compounds was evaluated and some of the compounds showed marked ascorbic acid equivalence Ferric reducing anti-oxidant power (FRAP) and metal chelating capacities. Crystal study of one representative of the synthesized series is also presented.
