Abstract
The invention relates to fumarates of antofine and antofine derivatives or pharmaceutically acceptable solvates thereof, and an application of the fumarates or the solvates in preparing drugs for treating cancers.
Description
Invention field
The present invention relates to pharmaceutical chemistry field, particularly, the present invention relates to organic acid salt and the pharmacy application thereof of alkaloid safe and reliable fragrant (antofine).
Background technology
For now, although the medicine for the treatment of cancer is existing a variety of, existing these medicines easily cause many and heavy untoward reaction, some generation resistances, and the result for the treatment of of existing medicine is still not ideal enough.Chinese invention patent application publication No. is in the patent application of CN 101962381 A, to have described some to have the active compound for the treatment of cancer.
Summary of the invention
The invention discloses some new compound, the preparation method of these compounds, the pharmacy application of the pharmaceutical composition that contains these compounds and these compounds and composition.
These compounds have shown good water-soluble stability and solid form stability.Some compound of these compounds shows special good stability.These compounds are compared with corresponding free alkali, and it has very high solvability in water.
These compounds are compared with corresponding free alkali and are shown that in surprise its anticancer activity is higher because of synergy between the two.
Surprising and the significant stability of these compounds, water-soluble, anticancer activity are effective preparation and a large amount of advantages that provide of using.
Therefore, the invention provides a kind of formula III compound:
｛（Ⅰ）H｝+Ⅱˉ;
Wherein the chemical structure of I is as follows:
Wherein the chemical structure of II is as follows:
And/or pharmaceutically acceptable solvate, wherein:
II-expression counter ion.
Suitable counter ion II-the comprise ion being provided by pharmaceutically acceptable organic acid.
The preferred acceptable organic acid of medicine comprises cholic acid, Chenodiol, ursodesoxycholic acid, Deoxycholic Acid, tartrate, toxilic acid, fumaric acid, particularly fumaric acid.
Preferred counter ion are fumarate ions.
Formula III compound is salt.
Suitable pharmaceutically acceptable solvate is hydrate.
In addition, the present invention also provides the preparation method of formula III and/or pharmaceutically acceptable solvate.This method comprises formula I compound:
React with counter ion Ⅱˉ defined above source, after this if necessary, then prepare its pharmaceutically acceptable solvate.
Suitable counter ion Ⅱˉ source is pharmaceutically acceptable organic acid.
The preferred acceptable organic acid of medicine comprises cholic acid, Chenodiol, ursodesoxycholic acid, Deoxycholic Acid, tartrate, toxilic acid, fumaric acid, particularly fumaric acid.
Preferred source of counter ions is fumaric acid.
Reacting normally between formula I compound and counter ion Ⅱˉ source carried out under conventional salt-forming condition, for example, in solvent, be generally C1---C4 alkanol solvent as ethanol, can provide under the arbitrary temp that generates required suitable speed, conventionally in the temperature raising for example at the temperature of solvent refluxing, be conveniently molar weight approximately to wait but preferably formula I compound mixed to then crystallization with counter ion Ⅱˉ source in the situation with slightly excessive counter ion Ⅱˉ source and go out required product (III).
The pharmaceutically acceptable solvate of formula III compound can be prepared by conventional chemical process.
Formula I compound can be prepared by the method for describing in the patent application of CN 101962381A according to Chinese invention patent application publication No..
Suitable source of counter ions is knownly through commercial sources, can easily obtain, fumaric acid for example, or can prepare required source of counter ions according to known method.
The stability of the compounds of this invention can be measured with conventional quantitative analysis method; For example the stability of solid chemical compound can be measured with the stability test of accelerating, for example dsc (DSC), thermo-gravimetric analysis (TGA) and the test of the thermoisopleth in intensification.This test comprises room temperature storage test.(in wherein during known under temperature and humidity control condition storage test compound).The quantitative analysis of test compound is before storage period, in storage period or after storage period.Stability with respect to suitable reference standard determination test compound.
As mentioned above, compound of the present invention is compared with corresponding free alkali, and it has significantly high solvability in water.The ordinary method of measuring like this stability of the compounds of this invention in the aqueous solution be included in known temperature condition and known during in mensuration in the aqueous solution of test compound, be settled out the degree of parent free alkali, we find that formula III compound demonstrates good aqueous stability.Particularly wherein the formula III compound of the fumaric acid radical of II-expression is stable especially in the aqueous solution.More surprised is formula III compound abnormal stablizing in the aqueous solution of the fumaric acid radical of wherein II-expression.
Described test compound quantitative analysis test can ordinary method, conventionally uses chromatography, and for example high pressure lipuid chromatography (HPLC) is carried out.
As mentioned above, compound of the present invention has practical therapeutic activity.
Therefore, the invention provides formula III compound and/or the pharmaceutically acceptable solvate as therapeutic active substance.
Like this, the invention provides formula III compound and/or the pharmaceutically acceptable solvate as treatment and/or inhibition cancer.
Formula III compound and/or pharmaceutically acceptable solvate can himself form be used, and the form that preferably also can contain the pharmaceutical composition of pharmaceutically acceptable carrier is used.
Therefore, the present invention also provides a kind of pharmaceutical composition that contains formula III compound and/or pharmaceutically acceptable solvate and pharmaceutically acceptable carrier.
Term used herein " pharmaceutically acceptable " comprises compound, composition and the component to people and animal doctor's use, and for example, term " pharmaceutically acceptable salt " comprises the upper acceptable salt of animal doctor.
Suitable pharmaceutical composition is the composition of unit dosage, for example oral liquid, tablet, capsule, injection liquid, sprays.
Optimum pharmaceutical composition is oral liquid, sprays.
According to the convention on conventional medicine, carrier can comprise thinner, weighting agent, disintegrating agent, wetting agent, lubricant, tinting material, seasonings or other conventional additives.
Optimum composition is to be configured to unit dosage.
Conventionally, activeconstituents can aforementioned pharmaceutical compositions form be used.
The present invention also provides a kind of contain formula III compound and/or the application of pharmaceutically acceptable solvate on the medicine of production for treating and/or inhibition cancer.
Provide embodiments of the invention below for further illustrating and describe in more detail the present invention.
