- C-benzo five-membered heteroaromatic aryl glucoside derivative as well as preparation method and application thereof
-
The invention discloses a C-benzo five-membered heteroaromatic aryl glucoside derivative shown in the general formula (I) (in the description), a preparation method of the derivative or an intermediate of the derivative, as well as application of the derivative. In the general formula (I), R, R1, R2, R3, R4, X and Y are defined in the description. The C-benzo five-membered heteroaromatic aryl glucoside derivative is novel in structure, has quite strong inhibitory activity on SGLT-2, has high selection ratio for SGLT-1 and SGLT-2, and can be used for preparing drugs for treating and preventing diseases relevant to SGLT-2.
