Medicinal chemistry, an evolving and interdisciplinary field, is the study of therapeutically active compounds. The very fact that Benzimidazoles are potential synthons for building synthetically a variety of chemical systems known for their broader biological and pharmacological applications. It is interesting to note that the important benzimidazole moiety is yet to be explored both synthetically and biologically in conjunction with several other biologically prominent heterocyclic systems, inspite of the extensive work reported so far on benzimidazoles by various research workers....
