  • Patent number: 10517867
    Abstract: The present disclosure provides a posaconazole derivative, a pharmaceutical composition and use thereof, which specifically include a compound represented by the following formula (I), a racemate, stereoisomer, tautomer, oxynitride, or a pharmaceutically acceptable salt thereof: The compounds of the present disclosure have strong antifungal activity, high safety, and good water solubility, without the need for the addition of a cosolvent (such as hydroxypropyl-?-cyclodextrin, sulfobutyl ether-?-cyclodextrin, and the like) with potential safety risks. Furthermore, the formulation process of the compound could have less difficulty and less cost, and therefore can be used to prepare improved antifungal drugs.
