Abstract
The invention relates to sofalcone crystals VIII, a preparation method thereof, a medicinal composition prepared from the sofalcone crystals VIII of the invention and use of the sofalcone crystals VIII. The sofalcone crystals VIII are characterized by the X-ray diffraction pattern and infrared spectrogram of the powder thereof.
Description
Technical field
The invention belongs to the pharmaceutical field of anti-gastric-ulcer, acute or chronic gastritis, more particularly, relate to [5-(3-methyl-2-butene base) oxygen base-2-[3-[4-(3-methyl-2-butene base) oxygen base] phenyl-1-oxo-2-propenyl of sofalcone (sofalcone) or formula (I)] phenoxy group] the crystal form V III and preparation method thereof of acetic acid, the pharmaceutical composition that contains it and the purposes in making anti-gastric-ulcer, acute or chronic gastritis medicine thereof.
Background technology
Sofalcone (sofalcone); chemistry [5-(3-methyl-2-butene base) oxygen base-2-[3-[4-(3-methyl-2-butene base) oxygen base] phenyl-1-oxo-2-propenyl by name] phenoxy group] acetic acid; a kind of gastric mucosa protective agent and tissue repair agent; can be used for the treatment of stomach ulcer, acute or chronic gastritis; developed by the large positive drugmaker of Japan, go on the market in Japan in March, 1984.
Chemical structure:
Molecular formula: C
27H
30O

Molecular weight: 450.5
Sofalcone is a kind of effective gastric mucosa protectant; can increase stomach volume of blood flow, expansion stomach mucous membrane blood vessel, increase the stomach-tissue oxygen-consumption, promote the stomach mucous membrane reparation, increase the coat of the stomach constituent, increase Prostaglandin in stomach-tissue, mainly bring into play its result for the treatment of by strengthening defense factor.Show through applying of clinical study and more than ten years, this medicine especially has curative effect preferably to stomach ulcer to peptide ulceration, also can be used for the treatment of the diseases such as chronic gastritis, has the advantages that curative effect is high, side effect is little.
The preparation method of this product has been reported both at home and abroad, as document Chem.Pharm.Bull.1979,27 (12): 2943～2953 and document U.S.4085135, Chinese patent CN1733682A, the preparation method of sofalcone, the pharmaceutical composition that contains them and preparation treatment stomach ulcer have been put down in writing in CN101434533A, the purposes of chronic gastritis medicine, but all do not relate to the crystal formation of sofalcone.
The poorly water-soluble of sofalcone is used in oral preparations at present, and in view of the pharmacy value of this compound, acquisition purity is high, this compound that have very definite crystal formation and favorable reproducibility is important.
Summary of the invention
An object of the present invention is to provide sofalcone crystal form V III.
Another object of the present invention is to provide the preparation method of sofalcone crystal form V III.
A further object of the invention is to provide sofalcone crystal form V III as effective constituent, and the medicinal compositions that contains one or more pharmaceutically acceptable carriers, vehicle or thinner, and at anti-gastric-ulcer, the application of chronic gastritis medicine aspect.
Now in conjunction with the object of the invention, content of the present invention is specifically described.
Sofalcone of the present invention has following structural formula:
Sofalcone crystal form V III has following characteristics:
Measure with D/Max-2500 type x-ray diffractometer, condition determination: CuKa, 40KV, 100mA, its collection of illustrative plates have following diffraction angle (2 θ), spacing (d value) and intensity (%), the error of 2 θ is 0.2.
Sofalcone crystal form V III, with Potassium Bromide (KBr) compressing tablet, the infrared spectrogram that records has following charateristic avsorption band:
3469cm
-1、2938cm
-1、2814cm
-1、2775cm
-1、1768cm
-1、1712cm
-1、1451cm
-1、?1418cm
-1、1239cm
-1、1115cm
-1、798cm
-1。
For the preparation of the sofalcone of sofalcone crystal form V III, can conveniently be made by two kinds of synthetic methods.A kind of is document Chem.Pharm.Bull.1979,27 (12): and the method for report in 2943～2953, reaction scheme is as follows:
Also have synthetic route and method in the patent CN101434533A that a kind of inventor of being applies for, be expressed as follows with reaction formula:
Synthetic sofalcone is refining with ethanol, and through proton nmr spectra (
1H-NMR), carbon-13 nmr spectra (
13C-NMR) prove conclusively its chemical structure (seeing accompanying drawing 1,2).Testing tool is Bruker AV 400 type nuclear magnetic resonance analyser, and deuterated reagent is the DMSO-d6 of CambridgeIsotope Laboratories company.The maximum single contaminant that high performance liquid chromatography (HPLC) records is 0.235%.
But above-mentioned product namely uses single solvent ethanol to re-refine twice, and maximum single contaminant still is not less than 0.2%.
The crystal form V III of sofalcone is that crystallization obtains in the mixed solution of hexanaphthene-tetrahydrofuran (THF).The usage quantity of mixed solution be 4～11 times of the sofalcone quality (volume-mass ratio, mL/g), wherein preferred 5～9 times.
Tetrahydrofuran (THF) accounts for 20～55% of mixed solution cumulative volume, and wherein preferred 30～50%.
Temperature during dissolving is 50 ℃～80 ℃.Then naturally be cooled to room temperature, placed 1～5 hour, namely obtain the new crystal VIII type of sofalcone.
Specific operation process is:
Get a certain amount of sofalcone, add hexanaphthene one tetrahydrofuran (THF) mixed solution, heated and stirred after dissolving, naturally cools to room temperature, then is incubated for some time.Separate out solid, filter, namely get sofalcone crystal form V III.
Then through the X-powder diffraction method, maximum infrared absorption spectrometry feature.
Do not contain crystal water and recrystallisation solvent in thermogravimetric analysis demonstration sofalcone crystal form V III.
