Design, synthesis, and investigation of biological activities ofnew triazole derivatives with antifungal effect

Fungal infections are an important cause of morbidity and mortality, especially in immunocompromised patients, the foremost of which is AIDS. In the last two decades, the incidence of such fungal infections has increased significantly, especially due to Candida species. The increasing incidence of life-threatening fungal infections has increased the need for new drugs to treat these infections. In this study, 10 triazole derivative compounds were synthesized. Analysis of the obtained compounds; 1H-NMR, 13C-NMR and HRMS spectroscopic methods are illuminated by the analysis findings. The inhibition effects of the obtained compounds on the 14α-demethylase enzyme were investigated. Among the synthesized compounds, 4a, 4c, 4d, 4e, 4g and 4c coded compounds were used against C. parapsilosis strain; Compounds 4c, 4f and 4g also showed significant inhibitory effect against C. albicans strain. Within the scope of the thesis, the interactions of 14α-demethylase enzyme active site and our compound were elucidated by molecular modeling and molecular dynamics studies. Enzyme active site and binding points were determined by docking studies for the selected compounds. The strongest interaction with 14α-demethylase enzyme active sites was observed in 4c and 4g coded compounds.
