Abstract

The present invention relates to the compound of heterozolotriazole ring and indole carboxylic acid represented by formula (I) having glycogen phosphorylase inhibitory activity and its salt, its preparation method and its preparation for treatment and / or prevention and treatment. Use in medicine for diseases related to abnormal glycogen metabolism.

Description

technical field [0001] The invention relates to the field of medicinal chemistry, in particular to a complex of heterozolotriazole ring and indole carboxylic acid as a glycogen phosphorylase inhibitor and a salt thereof, a preparation method and a medical application thereof. Background technique [0002] The main feature of diabetes is that the concentration of glucose in the blood is higher than the normal level for a long time, and there are two main sources of blood sugar: glycogenolysis and gluconeogenesis. According to relevant research reports, in the fasting state, about 3 / 4 of the fasting blood sugar comes from the glycogenolysis of the liver, and the rest comes from the gluconeogenesis of the liver. In patients with type 2 diabetes, the rate of hepatic glucose production is significantly increased and hepatic glucose production is high. Therefore, inhibiting hepatic glucose production has become one of the important targets for the development of new antidiabetic ...
