We have created novel 1,2,3-triazole-based benzothiazinone derivatives in the current work. The produced compounds' in vitro antioxidant, antifungal, and antitubercular properties were assessed. Moreover, a simulated molecular docking analysis was conducted on the cytochrome P450 lanosterol 14α-demethylase active site to elucidate the enzyme's binding affinity and interactions with synthesised benzothiazinone derivatives. A notable correlation between these compounds' antifungal activity and binding score was indicated by molecular docking data. The synthetic 1,2,3-triazole-based benzothiazinone derivatives may satisfy the structural criteria for creating novel antifungal drugs, according to the results of the in vitro and in silico investigations.
