Discovery of potential antifungal triazoles: design, synthesis, biological evaluation, and preliminary antifungal mechanism exploration.

A series of triazoles as miconazole analogues was designed, synthesized and characterized by IR, NMR, MS and HRMS. All the newly prepared compounds were screened for their antifungal activities against five kinds of fungi. The bioactive assay showed that most of the synthesized compounds exhibited good or even stronger antifungal activities in comparison with the reference drugs miconazole and fluconazole.

Synthesis of novel fluconazoliums and their evaluation for antibacterial and antifungal activities.

A series of novel fluconazoliums were synthesized and their bioactive evaluation as potential antibacterial and antifungal agents were described. Some target compounds displayed good and broad-spectrum antimicrobial activities with low MIC values ranging from 0.25 to 64 μg/mL against all the tested strains, including three Gram-positive bacteria (Staphylococcus aureus, MRSA and Bacillus subtilis), three Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa and Bacillus proteus) as well as two fungi (Candida albicans and Aspergillus fumigatus).
