The structures were confirmed by the elementary anal., ¹H-MR and IR spectra. MIC₈₀ of all the title compounds were determined by the method recommended by the National Committee for Clin. Laboratory Standards (NCCLS) using the RPMI1640 test medium. The results of the preliminary antifungal test show that all the title compounds exhibited potent antifungal activities to a certain extent. The antifungal activity of 1-(1H-1,2,4-triazol-1-yl)-2-(2,4-difluorophenyl)-3-(4-alkyloxyphenylpiperazin-1-yl)-2-propanols was more potent than that of 1-(1H,1,2,4-triazol-1-yl)-2-(2,4-difluorophenyl)-3-substituted sulfur ether-2-propanols in vitro. The antifungal activities of the four compounds in 1-(1H-1,2,4-triazol-1-yl)-2-(2,4-difluorophenyl)-3-(4-alkyloxyphenylpiperazin-1-yl)-2-propanols are more potent than that of fluconazole or equal to that of ketoconazole in vitro.

Sheng, Chunquan published the artcileImproved model of lanosterol 14α-demethylase by ligand-supported homology modeling: validation by virtual screening and azole optimization, Application In Synthesis of 86386-77-8, the publication is ChemMedChem (2010), 5(3), 390-397, database is CAplus and MEDLINE.

Lanosterol 14α-demethylase (CYP51) is an important target for antifungal drugs. An improved three-dimensional model of CYP51 from Candida albicans (CACYP51) was constructed by ligand-supported homol. modeling and mol. dynamics simulations. The accuracy of the constructed model was evaluated by its performance in a small-scale virtual screen. The results show that known CYP51 inhibitors were efficiently discriminated by the model, and it performed better than our previous CACYP51 model. The active site of CACYP51 was characterized by multiple copy simultaneous search (MCSS) calculations On the basis of the MCSS results, a series of novel azoles were designed and synthesized, and they showed good in vitro antifungal activity with a broad spectrum. The MIC₈₀ value of four of these compounds against C. albicans is 0.001 μg mL^-1, indicating that they are promising leads for the discovery of novel antifungal agents.

Wang, Wenya published the artcileDiscovery of highly potent antifungal triazoles by structure-based lead fusion, Application of 1-((2-(2,4-Difluorophenyl)oxiran-2-yl)methyl)-1H-1,2,4-triazole methanesulfonate, the publication is MedChemComm (2011), 2(11), 1066-1072, database is CAplus.

By means of structure-based lead fusion, a series of novel drug-like azoles possessing 4-(benzyloxy)piperidin-1-yl side chains were rationally designed and synthesized. Flexible mol. docking studies indicated that the newly synthesized azoles took advantages of the key interactions between the two lead structures and CACYP51. As a result, they revealed improved antifungal activity and broader spectrum. All the new azoles showed good to excellent in vitro antifungal activity against all of the tested pathogenic fungi (MIC₈₀ range: 2.33-0.01 μM). Compounds 10a, 10g and 10h, the most active azoles toward Candida albicans (MIC₈₀ = 0.01 μM) are 82 fold more potent than fluconazole. In particular, all the compounds also showed good activity against Aspergillus fumigatus (MIC₈₀ = 2.33-0.55 μM) that is not sensitive to fluconazole.
