Azole antifungals are commonly used to treat fungal infections but have resulted in the occurrence of drug resistance. Therefore, developing azole derivatives (AZDs) that can both combat established drug-resistant fungal strains and evade drug resistance is of great importance. In this study, we synthesized a series of AZDs with a fluconazole (FLC) skeleton conjugated with a mitochondria-targeting triphenylphosphonium cation (TPP+). These AZDs displayed potent activity against both azole-sensitive and azole-resistant Candida strains without eliciting obvious resistance. Moreover, two representative AZDs, 20 and 25, exerted synergistic antifungal activity with Hsp90 inhibitors against C. albicans strains resistant to the combination treatment of FLC and Hsp90 inhibitors. AZD 25, which had minimal cytotoxicity, was effective in preventing C. albicans biofilm formation. Mechanistic investigation revealed that AZD 25 inhibited the biosynthesis of the fungal membrane component ergosterol and interfered with mitochondrial function. Our findings provide an alternative approach to address fungal resistance problems.
Antibacterial drug and preparation method thereof

Paragraph 0028; 0041-0043; 0060; 0061, (2020/06/20)
The invention discloses an antibacterial drug. The antibacterial drug is 2-(2,4-difluorophenyl)-1-(1H-1,2,4-triazol-1-yl)-3-(1H-1,2,3,4-tetrazol-1-yl)-2-propanol, the compound is obtained by modifyingfluconazole and introducing a tetrazole ring. Compared with fluconazole, the compound has wider antimicrobial activity spectrum. The invention also discloses a preparation method of the antibacterialdrug. The method comprises the step of introducing the tetrazole ring to obtain 2-(2,4-difluorophenyl)-1-(1H-1,2,4-triazol-1-yl)-3-(1H-1,2,3,4-tetrazol-1-yl)-2-propanol on the basis of retaining moststructures with drug effects on fluconazole.
