herein are the same as those in the specification. It has been demonstrated by animal experiments that the tetrahydronaphtho[1,2-b]furan-2(3H)-one derivative can significantly inhibit the adjuvant-induced in Wistar male rats so that it can alleviate the primary and secondary lesions, showing a preventive activity to some extent. Therefore, the tetrahydronaphtho[1,2-b]furan-2(3H)-one derivative provided herein is applicable to the preparation of a drug for preventing/treating rheumatoid arthritis, and has promising clinical applications.
