Synthesis, Characterization and Biological Potency of Butyl‐Pyridone Based Azo Dyes

Abstract A series of heterocyclic disperse azo dyes having pyridone architecture was prepared by a simple, economical and highly efficient diazo‐coupling method. In this method, butyl pyridone was used as a common coupling component by changing the five heterocyclic amine moieties. The structural investigations of the analogous compounds were accomplished by various spectroscopic techniques. Further, all the azo dyes were examined for their potency towards antibacterial, antituberculosis and anticancer activities. The results revealed that all the dye molecules exhibited excellent tuberculosis activity and also very promising anticancer activity. In the case of the antibacterial assay, only a few azo dyes displayed good inhibition effect towards the tested bacterial strains.
