Abstract

The invention relates to nitrogen imidazole compounds and salts thereof. A chemical structure formula of the nitrogen imidazole compounds is as shown in the specification, wherein R is selected from hydrogen, halogen, cyanogroup and nitryl, can be located on an o-position, a meta-position and a para-position of a benzene ring, can be mono-substituted or poly-substituted. The invention further provides a preparation method and application of the compounds. The compounds are strong in antifungal activity for deep fungus, have the advantages of being efficient, low in toxicity, wide in antifungal spectrum and the like in comparison with an antifungal drug in existing clinical application, and therefore, the compounds can be used for preparing an efficient antifungal drug.

Description

【Technical field】 [0001] The present invention relates to the technical field of medicine, in particular to a class of nitrogen azole compounds 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 in clinical use have defects such as large toxic and side effects, narrow antibacterial spectrum, and easy to develop drug resistance. Effective anti...
