Synthesis, Аntibacterial, Аntifungal, and Antioxidant Activity of New (Benzo)Imidazo[2,1-b][1,3]Thiazine Quaternary Salts
A series of quaternary salts – 1-phenacyl(4-chlorophenacyl)-6-hydroxy-6,7-dihydro-5H-benzo[4,5]imidazo[2,1-b][1,3]thiazinium bromides 4a-f were obtained. Their structures were rigorously proven by the methods of 1H NMR, 13C NMR spectroscopy, and chromatography-mass spectrometry. All obtained compounds were tested in in vitro experiments for antibacterial, antifungal, and antioxidant activity.
