Abstract
The invention relates to dehydrocrebanine, a fumarate of a dehydrocrebanine derivative, or a pharmacologically acceptable solvate of the fumarate, and applications of the pharmacologically acceptable solvate in preparation of drugs used for controlling methicillin-resistant staphylococcus aureus.
Description
Invention field
The present invention relates to pharmaceutical chemistry field, particularly, the present invention relates to dehydrocrebanine organic acid salt and pharmacy application thereof.
Background technology
For now, although the medicine of methicillin-resistant staphylococcus aureus resistance is existing a variety of, existing these medicines easily cause many and heavy untoward reaction, 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 specification of CN 101822675A, to have described some and have the active compound of methicillin-resistant staphylococcus aureus resistance.
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 the activity of its methicillin-resistant staphylococcus aureus resistance is higher because of synergy between the two.
Surprising and the significant stability of these compounds, water-soluble, anti-microbial activity are effectively preparation and a large amount of advantages that provide that use.
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 defined above II-source, after this if necessary, then prepare its pharmaceutically acceptable solvate.
Suitable counter ion II-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 II-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 at the temperature of for example solvent refluxing of temperature raising, be conveniently molar weight approximately to wait but preferably formula I compound mixed to then crystallization with counter ion II-source in the situation with slightly excessive counter ion II-source and go out required product (III).
The pharmaceutically acceptable solvate of formula III compound can be prepared by conventional chemical process.
Prepared by the method that formula I compound is described in can the patent specification that be CN101822675A according to Chinese invention patent application publication No..
Suitable source of counter ions is knownly can easily obtain through commercial sources, for example fumaric acid, 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; The stability of for example solid chemical compound can be measured with the stability test of accelerating, for example dsc (DSC), and thermo-gravimetric analysis (TGA) is tested with 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.With respect to the stability of 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 be settled out the degree of parent free alkali in the aqueous solution of mensuration by test compound, 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 methicillin-resistant staphylococcus aureus resistance.
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 producing methicillin-resistant staphylococcus aureus resistance.
Provide embodiments of the invention below for further illustrating and describe in more detail the present invention.
Embodiment 1
