Abstract

The invention discloses an amidophenyl-1,3,4-oxadiazole compound shown in the formula (I). The invention also discloses a preparation method of the amidophenyl-1,3,4-oxadiazole compound. The preparation method comprises that an amino-compound II and a substituted aliphatic acid III are condensed to form the amidophenyl-1,3,4-oxadiazole compound. The invention also discloses a use of the amidophenyl-1,3,4-oxadiazole compound I in preparation of a drug for treating type II diabetes. The amidophenyl-1,3,4-oxadiazole compound has a non-AMP structure type, can reduce side-effect risk, can obviously inhibit FBPase in a molecule level, can substantially inhibit glucose generation in a cell level, and has good cell viability and good druggability.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to amide phenyl-1,3,4-oxadiazole compounds, a preparation method and application thereof. Background technique [0002] Diabetes is a chronic disease that occurs when the pancreas does not produce enough insulin or the body cannot effectively use the insulin it produces. The World Health Organization (WHO) estimates that approximately 285 million people worldwide currently suffer from diabetes. This figure is likely to more than double by 2030. Ninety percent of diabetics around the world have type 2 diabetes, which is the result of the body's inability to use insulin effectively. [0003] Due to different causes, diabetes can be divided into four types, namely: type I, type II, gestational diabetes and other types. Among them, patients with type II diabetes account for more than 90%. It is characterized by insulin resistance (i.e. decreased sensitivity of tissues in the body to ...
