Abstract

The invention is a sulfur / nitrogen-containing azole antifungal compound as well as a preparation method and an application of the sulfur / nitrogen-containing azole antifungal compound, relates to the technical field of medicine. The sulfur / nitrogen-containing azole antifungal compound is a novel azole antifungal compound and has a chemical structural formula which is shown in the specification, wherein, R1 is hydrogen or a straight-chain or branched-chain saturated or unsaturated lower alkyl having 1-6 carbon atoms; R2 is selected from hydrogen, alkyl, halogen, cyano group, a nitro group, an amino and an alkoxy, can be located at the ortho, meta or para position of the benzene ring and can be monosubstituted or polysubstituted. The invention also provides a preparation method and an application of the compound. The compound disclosed by the invention has strong antifungal activity on the deep fungal, has the advantages of high efficiency, low toxicity, broad anti-fungal spectrum and the like compared with the current clinically applied antifungal drugs, and therefore, the compound can be used for the preparation of efficient antifungal agents.

Description

technical field [0001] The invention relates to the field of medical technology, and is a novel nitrogen azole antifungal compound—N-alkyl-N-(2-(2,4-difluorophenyl)-2-hydroxy-3-(1H-1,2, 4-triazol-1-yl))-propyl-aminodithiocarbamic acid benzyl ester compounds and salts thereof, as well as their preparation methods and uses. 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 in clinical us...
