Abstract

The invention discloses novel organic berberine glycyrrhetinic acid enantiomeric salts used for medicines and a production method and application thereof. The chemical name of the organic berberine glycyrrhetinic acid enantiomeric salts is: 5,6-dihydrogen-9,10-dimethoxybenzo[g]-1,3-benzodioxolane[5,6-a]quinolizidine.18a(beta),3beta-hydroxyl-11-oxooleanane-12-olefine-30-formate. The production method comprises the following steps of: respectively dissolving berberine and a glycyrrhetinic acid enantiomer in 80 percent ethanol according to a medicament eutecticum principle, mixing the two liquids, stirring for 2 hours, removing the ethanol under reduced pressure, and treating by using ethyl acetate to prepare the berberine glycyrrhetinic acid enantiomeric salts. The organic salts with dual parent nuclei have positive practical significance for resisting diseases such as tumors, diabetes, chronic inflammatory diseases such as rheumatoid arthritis, hepatitis, Alzheimer disease and the like of human and developing medicines.

Description

technical field [0001] The present invention relates to a new compound that can be used for the treatment of diseases such as tumors and diabetes, specifically a compound salt formed by combining berberine and glycyrrhetinic acid, which is the different enantiomer 18a-glycyrrhetinic acid of berberine and glycyrrhetinic acid Or 18β-glycyrrhetinic acid combined salt. Background technique [0002] Berberine is an isoquinoline alkaloid extracted from Coptis chinensis of the family Ranunculaceae, and is the main component of Chinese medicine Coptis chinensis. In the past, it was often believed that it was not easy to absorb after oral administration, and because it is effective against intestinal infections caused by Shigella, Escherichia coli, and Staphylococcus aureus, conjunctivitis, suppurative otitis media, etc., it is mainly used clinically for the treatment of intestinal infections. With the deepening of research, in recent years, it has been found that it has pharmacolog...
