Abstract

Disclosed is a bis(2-ethyl-3hydroxy-4-pyranone) copper(II) complex and its use in treating diabetes, which relates to heterocyclic compound having oxygen atoms, especially a copper central ionic 2-ethyl-3-hydroxy-4-pyranone chelate and its use. The copper complex has a molecular formula of C14H14CuO6, and a formula weight of FW=341.5. The compound can be made into oral administration medicines against diabetes.

Description

Technical field [0001] The invention relates to heterocyclic compounds containing oxygen atoms, in particular to 2-ethyl-3-hydroxyl-4-pyrone chelates with copper as the central ion and applications thereof. Background technique [0002] Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia caused by insulin secretion defect and its biological action disorder, which can lead to a series of complications and endanger human health. Modern research shows that Cu is an essential trace element for the human body. It is the active center of many redox proteases and plays an important role in the metabolism of glucose [Edited by Yang Kedi. Trace Elements and Health. Science Press. First Edition. 2003, p91-106]. Epidemiological surveys have shown that there is copper deficiency and deficiency in diabetic patients, and copper-containing compounds can make animal models of diabetes show the activity of lowering blood sugar and i...
