Formula: C7H5N3O2S《Synthesis, Characterization and Biological Potency of Butyl-Pyridone Based Azo Dyes》 was published in 2020. The authors were Kumar, Vinod;Keshavayya, J.;Matada, Mallikarjuna N.;Srinivasa, Sudhanva M.;Rangappa, S., and the article was included in《ChemistrySelect》. The author mentioned the following in the article:
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, Bu 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 mols. 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. And 6-Nitrobenzo[d]thiazol-2-amine (cas: 6285-57-0) was used in the research process.
6-Nitrobenzo[d]thiazol-2-amine(cas:6285-57-0 Formula: C7H5N3O2S) inhibits the activity of amines, which are small molecules found in many pharmaceuticals. The chemical structure of this drug contains one or more methylene groups that can be activated by diazonium salt to form an intermediate molecule with a reactive amine group.
