Abstract: In this work, a series of novel 1,2,4-triazole derivatives with selenium-containing hydrophobic side chains were designed and synthesized based on the structure of lanosterol 14α-demethylase (CYP51). All compounds were characterized by HRMS, 1H NMR and 13C NMR. Then, their antifungal activities against eight human pathogenic fungi were evaluated in vitro by testing the minimal inhibitory concentrations. The results showed that nearly all tested compounds were found to be more potent against all tested fungal strains than control drug fluconazole. Further mechanism study demonstrated that the target compounds had fungal CYP51 inhibitory activity. Meanwhile, representative compounds revealed low cytotoxic effects toward mammalian cell lines. In addition, the docking results showed that the target compounds bound to Candida albicans CYP51 in a better pattern than fluconazole, especially in the narrow hydrophobic cleft. Overall, the novel 1,2,4-triazole derivatives with selenium-containing hydrophobic side chains can be further developed for the potential treatment of invasive fungal infections.
