- Design, synthesis and antifungal evaluation of 1-(2-(2,4-difluorophenyl)-2- hydroxy-3-(1H-1,2,4-triazol-1-yl)propyl)-1H-1,2,4-triazol-5(4H)-one
-
Based on the structure of the active site of cytochrome P450 14α-demethylase (CYP51) and the conclusions of the structure-activity relationships of azole antifungals, a series of 1-(2-(2,4-difluoro-phenyl)-2- hydroxy-3-(1H-1,2,4-triazol-1-yl)propyl)-1H-1,2,4-triazol-5(4H)-one of fluconazole analogs was synthesized. All compounds were characterized by IR, HRMS, 1HNMR and 13C NMR spectroscopic analysis. Results of preliminary antifungal in vitro test using eight human pathogenic species showed that some compounds displayed comparable or even better antifungal activities than reference drug fluconazole and that compound 3i exhibited significant activity against Candida albicans being worthy of further optimization.

- Design and synthesis of novel triazole antifungal derivatives by structure-based bioisosterism
-
The incidence of life-threatening fungal infections is increasing dramatically. In an attempt to develop novel antifungal agents, our previously synthesized phenoxyalkylpiperazine triazole derivatives were used as lead structures for further optimization. By means of structure-based bioisosterism, triazolone was used as a new bioisostere of oxygen atom. This type of bioisosteric replacement can improve the water solubility without loss of hydrogen-bonding interaction with the target enzyme. A series of triazolone-containing triazoles were rationally designed and synthesized. As compared with fluconazole, several compounds showed higher antifungal activity with broader spectrum, suggesting their potential for further evaluations.
