Abstract

The invention belongs to the technical field of medicaments, in particular relates to a benzocyclodirivative as shown in a general formula (I) as well as pharmaceutically acceptable salts, a hydras and an isomer thereof, wherein R1, R2, R3, R4, Q, X and Y are defined in the specification. The invention also relates to a preparation method of the compounds, a pharmaceutical composition containing the compounds and application of the compounds in preparing medicaments for treating and / or preventing non-insulin-dependent diabetes mellitus.

Description

1. Technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to benzocyclic derivatives, pharmaceutically acceptable salts thereof, stereoisomers or solvates thereof, preparation methods of these compounds, pharmaceutical compositions containing these compounds, and these compounds Application in preparation of medicine for treating and / or preventing non-insulin dependent diabetes. 2. Background technology [0002] Diabetes is a systemic chronic metabolic disease caused by uncontrolled blood sugar levels higher than normal. Basically divided into four categories, including: type I (insulin-dependent), type II (non-insulin-dependent), other types and gestational diabetes. Type 1 and type 2 diabetes belong to primary diabetes, the two most common forms, caused by the interaction of genetic and environmental factors. The etiology of diabetes is very complex, but in the final analysis is due to absolute or relative lack of insuli...
