Embodiment 1
[0030] Embodiment 1 Preparation of the compound of the present invention
[0031] (1) Preparation of 2-(2,4-difluorophenyl)-2-hydroxyl-3-(1 H -1,2,4-triazol-1-yl)diethylaminodithiocarbamate (compound 1k in Table 1):
[0032] 1-[2-(2,4-difluorophenyl)-2,3-epoxypropyl]-1 H 10g of -1,2,4-triazole mesylate was dissolved in 100mL ethyl acetate and 100mL saturated sodium carbonate solution, then shaken and separated, and the organic layer was washed once with 50mL saturated sodium carbonate solution and 50mL saturated sodium chloride solution. , dried over anhydrous sodium sulfate. Filtration, evaporation of the solvent to give intermediate 1-[2-(2,4-difluorophenyl)-2,3-epoxypropyl]-1 H -1,2,4-triazole.
[0033] Put a magnet into a 50mL single-necked bottle, add 10mL absolute ethanol and 0.21mL diethylamine (2mmol). After 10 min of ice-water bath, 0.12 mL of carbon disulfide (2 mmol) was added dropwise under rapid magnetic stirring, and kept stirring in the ice bath for 30 min...

Abstract
The invention provides an azole antifungal compound and its pharmaceutically acceptable salt. The structural general formula of the azole antifungal compound is shown in the specification, wherein R is selected from various aliphatic primary amine or secondary amine, aromatic primary amine or secondary amine and various substituted phenylpiperazine; the substituent group on phenyl of the substituted phenylpiperazine is hydrogen, alkyl group, halogen, cyanogroup, nitro-group, amino group or alkoxy group, is arranged at ortho, meta or para position of phenyl ring, and is monosubstituted or polysubstituted; the alkyl group is the alkyl group with 1-4 carbon atoms; the halogen is selected from F, Cl, Br or I; and the alkoxy group is selected from methoxy, ethoxy and t-butyl oxygroup. The compound provided by the invention has strong antifungal activity to deep fungi. In comparison with present antifungal drugs applied in clinic, the compound provided by the invention has advantages of high efficiency, low toxicity, wide antifungal spectrum and the like. Thus, the compound can be applied to prepare antifungal drugs. A preparation method of the compound is simple and has high yield. The prepared compound has a good antifungal effect.
Description
technical field [0001] The invention relates to the technical field of pharmaceutical compounds, in particular to an azole antifungal compound and its preparation method and application. Background technique [0002] In recent years, with the widespread application of broad-spectrum antibiotics, antineoplastic drugs, and immunosuppressants, the widespread development of peritoneal dialysis, organ transplantation, and radiotherapy, and the rapid spread of immunodeficiency diseases, especially AIDS, Candida albicans, Cryptography neoformans The incidence of opportunistic deep fungal infections such as coccus and Aspergillus fumigatus has increased dramatically. Deep fungal infection has risen to the third largest infectious disease clinically, seriously threatening human life and health. Most of the antifungal drugs currently used in clinical practice have the disadvantages of large toxic and side effects, narrow antibacterial spectrum, and easy drug resistance. Effective ant...
