Problems solved by technology

[0008] Chuanhuning (dehydroandrographolide succinate half-ester monopotassium salt) increases its water solubility after salting the free carboxyl group, and mostly forms potassium and sodium salts; however, the potassium salt is highly alkaline, which affects the stability of the ester bond, and The recrystallization effect is not good, affecting the purity

Abstract

The invention provides a dehydroandrographolide glycine semi-ester hydrochloride derivative composition. The composition comprises dehydroandrographolide glycine semi-ester hydrochloride, a metal complexing agent and / or other pharmaceutically acceptable carriers. The invention also provides a preparation method as well as application of the composition. The composition can be used for adjusting the nonspecific immunity function, and has anti-tumor, anti-pyretic, anti-inflammatory, anti-virus, liver protection, cholagogic, anti-diabetic, anti-fertility and cardiovascular protection effects. The purity of the active ingredient of the composition is high, and the risk of adverse effect caused by impurities is avoided; the composition is in a scientific proportion, so that the stability of the medicament is greatly improved and other serious adverse events caused by degradation and polymer formation occurring in manufacturing and storage of the medicament are avoided; the composition has a better curative effect and an excellent effect on the adjustment of the nonspecific immunity function.

Description

technical field [0001] The invention belongs to the technical field of medicine and relates to a dehydroandrographolide derivative composition and its preparation method and application, in particular to a dehydroandrographolide glycine half ester hydrochloride composition and its preparation method and application. Background technique [0002] Andrographolide is a diterpene lactone compound extracted from Andrographis paniculata, a plant of the Acanthaceae family. It is one of the main active ingredients of the traditional Chinese medicine Andrographis paniculata. It has the functions of clearing away heat and detoxification, cooling blood and reducing swelling. Andrographolide is insoluble in water, and different hydrophilic groups need to be introduced into the lactone structure to enhance its water solubility, so as to exert corresponding pharmacological effects. A large number of andrographolide derivatives such as Xiyanping injection, Chuanhuning injection, Yanhuning ...
