Abstract

The invention relates to a triazole alcohol derivative, a preparation method and application thereof. The triazole alcohol derivative is a 2-(2, 4-difluorophenyl)-3-(1-substituted-1H-1, 2, 3-triazole-4-yl)-1-(1H-1, 2, 4-triazole-1yl)-2-propanol compound. The invention also provides a salt of the compound, a pharmaceutical composition, a preparation method and application thereof. The compound provided by the invention has strong antifungal activity, and has the advantages of low toxicity, broad antibacterial spectrum and the like, and can be used for preparation of antifungal drugs.

Description

technical field [0001] The invention relates to the technical field of medical compounds, in particular to a novel triazole alcohol derivative and its preparation method and application. Background technique [0002] In recent years, with the extensive application of broad-spectrum antibiotics, antineoplastic drugs, and immunosuppressants, the widespread implementation of radiotherapy and organ transplantation, the widespread development of catheters and intubations, and the rapid increase in immunocompromised patients, especially AIDS patients, have resulted in Fungal infections, especially deep fungal infections, have risen sharply, and deep fungal infections have become the main cause of death from major diseases such as AIDS and tumors. However, as far as the antifungal drugs in clinical use are concerned, there are problems such as large side effects, narrow antibacterial spectrum, and easy drug resistance. Effective antifungal drugs, especially anti-deep fungal drugs, ...
