Synthesis, Characterization, And Bioactivity Studies Of Triazolothiadiazines As Potential Antifungal Agents

Abstract

The escalating issue of antifungal resistance necessitates the development of novel therapeutic agents, particularly those containing azole scaffolds (Synthesis, Antifungal Activities, Molecular Docking and Molecular ..., 2023). This research focuses on the synthesis, comprehensive characterization, and evaluation of the bioactivity of triazolothiadiazine derivatives as promising antifungal candidates (Synthesis, Antifungal Activities, Molecular Docking and Molecular ..., 2023). A series of seventeen novel triazole derivative compounds were synthesized, with their structures rigorously elucidated using spectroscopic methods including 1H-NMR, 13C-NMR, and HRMS (Synthesis, Antifungal Activities, Molecular Docking and Molecular ..., 2023). Further structural confirmation was achieved through two-dimensional NMR techniques such as HSQC, HMBC, and NOESY (Synthesis, Antifungal Activities, Molecular Docking and Molecular ..., 2023).

The antifungal efficacy of these compounds was assessed in vitro against various Candida strains, revealing significant inhibitory activities (Synthesis, Antifungal Activities, Molecular Docking and Molecular ..., 2023). Notably, compound 5d demonstrated potent activity against Candida glabrata and Candida krusei with a MIC90 value of 2 µg/mL, surpassing the activity of fluconazole and indicating its promising potential (Synthesis, Antifungal Activities, Molecular Docking and Molecular ..., 2023). Additionally, the study evaluated the compounds' ability to inhibit biofilm formation, a critical virulence factor in fungal infections (Synthesis, Antifungal Activities, Molecular Docking and Molecular ..., 2023). Molecular docking and molecular dynamics simulations were conducted for compound 5d, which corroborated the observed antifungal activity and provided insights into its mechanism of action (Synthesis, Antifungal Activities, Molecular Docking and Molecular ..., 2023). These findings underscore the potential of triazolothiadiazines as a new class of antifungal agents, warranting further investigation for therapeutic applications.
