Sulfa drugs are well-known antibacterial agents containing N-substituted sulfonamide group on para position of aniline ring (NH2RSO2NHR'). In this study 2,4-dichloro-1,3,5-triazine derivatives of sulfa drugs, sulfamerazine (1b), sulfaquinoxaline (2b), sulfadiazine (3b), sulfadimidine (4b), and sulfachloropyrazine (5b) (1a-5a) were synthesized and characterized. Their carbonic anhydrase inhibiti...

ABSTRACT. The present study is aimed to synthesise Schiff bases from sulfathiazole/ sulfamethoxazole/ sulfadimidine with 2-hydroxybenzaldehyde. synthesized were characterized by analytical data, IR, 1H-NMR, 13C-NMR, UV-Vis spectra, mass spectra and screened for antibacterial activity against gram positive bacteria Staphylococcus aureus negative Salmonella typhiand antifungal Candida albicans Mu...
