Technical field
The present invention relates to the nitrate derivatives and the atoxic pharmacy acceptable salt thereof of Potenlini and glycyrrhetinic acid and contain these compounds as the pharmaceutical composition of activeconstituents and in the application for preparing aspects such as hepatitis treatment medicine and ulcer treatment medicine; The invention still further relates to the preparation method of the nitrate derivatives and the atoxic pharmacy acceptable salt thereof of Potenlini and glycyrrhetinic acid.
Background technology
The present invention relates to the nitrate derivatives and the atoxic pharmacy acceptable salt thereof of Potenlini and glycyrrhetinic acid, and their preparation method, and the medicine composition that contains these compounds, and Potenlini or the nitrate derivatives of glycyrrhetinic acid and the method for atoxic pharmacy acceptable salt treatment hepatitis and peptide ulceration etc. thereof by awarding effective therapeutic dose.
Potenlini (Glycyrrhizic acid, GA), claim glycyrrhizin (Glycyrrhizin again, GL), chemical name 3-O-(2 '-beta d glucopyranosiduronic acid base)-beta d glucopyranosiduronic acid glycosides 3 beta-hydroxies-11-carbonyl oxygen-18 β volatile oil-12-alkene-30-carboxylic acid (English chemical name: 3-O-(2 '-β-D-glucuronopyranosyl)-β-D-glucuronopyranoside 3 β-hydroxy-11-oxo-18 β olean-12-en-30-oic acid), be the effective constituent of separation and Extraction from Radix Glycyrrhizae.Natural isolating Potenlini is 18 beta isomers, and 18 beta isomers can be converted into 18 αYi Goutis by ad hoc approach.Its chemical structure is as follows:
Figure A20051005151100061
Potenlini beta isomer Potenlini αYi Gouti
Carboxyl in the Potenlini molecule can become single salt, two salt or three salt with various positively charged ions such as sodium ion, potassium ion, ammonium ion, zine ion, magnesium ion etc.Studies show that Potenlini has anti-inflammatory, antiviral and effects such as protecting liver and detoxication and raise immunity, clinically be widely used in treating various acute, chronic hepatitis.What clinical application was more is beta isomer mono-ammonium (commodity are called potenlin) and αYi Gouti di-ammonium salts (commodity are called Glycyrrhizic acid,diammonium salt, chief editors such as Chen Xinqian, new pharmacology, the 15th edition, People's Health Publisher, 2004, the 472 pages); Formulation has injection liquid or capsule, respectively by injection administration or oral administration; These preparations have and significantly fall enzyme, anti-inflammatory and hepatoprotective effect.
Potenlini is that (glycyrrhetinic acid is the active metabolite of Potenlini for GlycyrrhetinicAcid, GLA) performance pharmacological action by being converted into its aglycon glycyrrhetinic acid in vivo; External, can Potenlini be converted into glycyrrhetinic acid by hydrolysis.The chemical structure of glycyrrhetinic acid is as follows:
Glycyrrhetinic acid beta isomer glycyrrhetinic acid αYi Gouti
The preparation that contains Potenlini or glycyrrhetinic acid and derivative thereof also has Radix Glycyrrhizae fluidextract or FUFANG GANCAO PIAN to be used for the cough-relieving what is said or talked about of dispelling, treatment upper respiratory tract infection and bronchitis (chief editor such as Chen Xinqian, new pharmacology, the 15th edition, the People's Health Publisher, 2004, the 421 pages); Zinc glycyrrhizate and liver Meticortene Solu-Delta-cortef are used for the treatment of peptide ulceration (chief editor such as Chen Xinqian, new pharmacology, the 15th edition, People's Health Publisher, 2004, the 440,442 pages).
But, also there are some untoward reactions in Potenlini or glycyrrhetinic acid and derivative thereof in clinical application, mainly contain and receive poor, nauseating, vomiting, abdominal distension, skin pruritus, urticaria, dry, edema, dizziness, uncomfortable in chest, palpitaition, blood pressure and increase, side effect (the chief editor such as Chen Xinqian who also has some steroid samples, new pharmacology, the 15th edition, the People's Health Publisher, 2004, the 421,440,442 and 472 pages).Therefore need more effective and side effect glycyrrhizin derivative still less, to be used for the treatment of diseases such as hepatitis, peptide ulceration and virus infection.
