Abstract

The invention discloses the application of the composition of benzenebutanoic acid and a triazole antifungal drug and an antifungal product. Static and dynamic combined antifungal activity, on drug-resisting candida albicans (CA), of the composition of the triazole antifungal drug and benzenebutanoic acid is researched. When PBA is combined with FLC, ITC and VRC, the antimicrobial activity of the triazole antifungal drug on drug-resisting CA can be improved, a synergic antifungal effect can be realized, the drug resistance of drug-resisting CA on the triazole antifungal drug can be reversed, and a research direction is provided for development of new drugs and new application of old drugs. For CA (MIC>=512 mug / ml) resistant to FLC, ITC and VRC, minimal inhibitory concentration can be reduced remarkably through drug combination, over 80% fungi can be killed through combination of PBA of 32 mug / ml and FLC of 1 mug / ml, combination of PBA of 32 mug / ml and ITC of 0.125 mug / ml, and combination of PBA of 16 mug / ml and VRC of 0.25 mug / ml, and the effect is better as concentration becomes higher.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to the application of phenylbutyric acid combined with triazole antifungal drugs and the products thereof. Background technique [0002] With the increase of patients with acquired immunodeficiency syndrome and the wide application of broad-spectrum antibacterial drugs, the development of medical technologies such as organ transplantation technology and catheter technology, the morbidity and mortality of invasive fungal infections are also increasing year by year. The morbidity and fatality rate of bacteria reached 40%, occupying the fourth place in the hospital acquired bloodstream infection. Among them, Candida albicans (Candida albicans, CA) is a common isolate in clinical fungal infections, usually treated with azole antifungal drugs fluconazole (Fluconazole, FLC), voriconazole (Voriconazole, VRC), itraconazole azole (Itraconazole, ITC) treatment. As a safe, effective and che...
