Abstract

The invention belongs to the field of pharmaceutical preparations, in particular discloses a water-soluble triazole antifungal compound and a preparation method thereof. The water-soluble triazole antifungal compound has a structural formula like a formula Ia, a formula Ib or a formula Ic, wherein R1 is a group of a formular II. The compound is formed by inducing a new group on a structural basis of a broad-spectrum and high-efficiency antifungal compound in the processes of clinical application and new drug development so as to improve the water solubility of the compound and lower the toxicity, is used as a prodrug of triazole antifungal medicaments and has the advantages of wide antifungal spectrum, strong antifungal activity resistance, good safety, and the like.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to a water-soluble triazole antifungal compound and a preparation method thereof. Background technique [0002] Triazole is a five-membered heterocyclic ring in which one carbon atom in the imidazole ring is replaced by nitrogen. As a pharmacophore, triazole has lower toxicity than imidazole, and it is widely used in many types of medicines and pesticides. So far, there have been many The triazole drugs are used in clinical and agricultural; as an important functional group, triazole has a strong ability to complex metal ions and form hydrogen bonds, so it is favored in the chemical field. [0003] Triazole antifungal drugs are currently the most widely used drugs for the treatment of mycoses, especially deep mycoses. Its mechanism of action is that N-4 on the triazole ring coordinates with the iron atom of the iron porphyrin center in the fungal cytochrome P-450 to inhibit...
