Abstract

The invention discloses an azacyclic transition metal zinc complex containing multiple coordination sites, and a preparation method and application of the azacyclic transition metal zinc complex. The azacyclic transition metal zinc complex is a 1-(benzotriazole-1-methyl)-1-(2-ethyl imidazole) zinc complex, and has a molecular formula of [Zn (SCN) 2(C12H13N5)2]. The azacyclic transition metal zinc complex, namely, the 1-(benzotriazole-1-methyl)-1-(2-ethyl imidazole) zinc complex provided by the invention has a higher inhibiting effect for alpha-amylase, and the inhibiting effect of the 1-(benzotriazole-1-methyl)-1-(2-ethyl imidazole) zinc complex is much higher than that of singly-used 1-(benzotriazole-1-methyl)-1-(2-ethyl imidazole) or transition metal salt for the alpha-amylase and is higher than that of commonly-used hypoglycemic agent acarbose for the alpha-amylase. Therefore, the azacyclic transition metal zinc complex is proved to have a good hypoglycemic effect so as to be effectively used for preparing medicines for treating diabetes mellitus, and is an innovation in the aspect of medicines for treating the diabetes mellitus.

Description

technical field [0001] The invention relates to a nitrogen-heterocyclic transition metal zinc complex containing multiple coordination points, a preparation method and application, and belongs to the technical field of medicine. Background technique [0002] Diabetes is a metabolic disease characterized by high blood sugar. The long-term high blood sugar in diabetes can easily lead to chronic damage and dysfunction of various tissues, especially the eyes, kidneys, heart, blood vessels, and nerves. At present, the global prevalence of diabetes is in a period of rapid rise, and my country has become the country with the largest number of diabetic patients in the world. According to relevant reports, among the numerous diabetic patients, type 2 diabetes patients account for 90%-95%. It has become one of the major diseases threatening human health. [0003] At present, the methods adopted for the treatment of type 2 diabetes mainly include: oral hypoglycemic drugs, insulin in...
