Abstract
A stable oil-in-water emulsion of matrine-type alkaloid for intravenous injection is prepared from matrine, soybean oil, water and lecithin.
Description
Invention field
The present invention relates to matrine type alkaloid, it is specifically related to for the matrine alkaloid for venous purpose composition and method of making the same.
Background of invention
Matrine type alkaloid (Matrine type alkaloid) is that a class has matridinde-similar chemical compound of 15-ketone (Matridin-15-ketone) basic chemical structure, at present known have nearly over one hundred kind of chemical constituent, and clear and definite its main effective ingredient is an alkaloid.They extensively are present in leguminous plant Radix Sophorae Flavescentis (Sophora flavescens Ait.), Herba Sophorae alopecuroidis (sophora alopecuroides L.) and the root of subprostrate sophora (S.Subprostrata Chun et T.Chen), are the main effective ingredient of these several Chinese herbal medicine commonly used.Along with the continuous development and progress of separation and extraction technology, successively separated different matrine type alkaloid monomers in succession in recent years.Wherein commonly used have matrine (matrine), oxymatrine (oxymatrine), sophoridine (sophoridine), aloperine (aloperine), sophocarpine (sophocarpine), sophoramine (sophoramine), sophoranol alkali (sophoranol), a N-oxysophocarpine (oxysophocarpine) etc.It is the framing structure of representative that matrine type alkaloid all has with the matrine, promptly belongs to tetracyclic quinolizine pyridine class (quinolizidine), and molecular skeleton can be regarded the body that condenses of two quinolizine pyridine rings as.
One of main alkaloid that matrine goes out as extraction separation in Chinese medicine Radix Sophorae Flavescentis (sophora flavesceus AIT) or Herba Sophorae alopecuroidis (sophoraalopecuroides L) and other plant, prove through pharmaceutical research, multiple biological activity is arranged, as antitumor, antiinflammatory, anti-arrhythmia, prevent hepatic fibrosis, improve effects such as liver function.Clinical being used for fallen effects such as enzyme to symptom and sign, jaundice eliminating that the alanine aminotransferase of chronic hepatitis patient and bilirubin recover normal, diuresis jaundice eliminating, detoxifcation and improve hepatitis, also can suppress duplicating of hepatitis B virus, and leukopenia etc. due to can be used to prevent and treat chemotherapy of tumors the time.So the exploitation of the good preparation of matrine is then become the key of its disease treatment of performance.
The listing dosage form of matrine comprises injection matrine, matrine sodium chloride injection, matrine glucose injection, matrine bolt at present.Non-vein drug-delivery preparation such as matrine suppository, the non-vein low bioavailability of matrine injection, tangible local pain during the injection intramuscular injection, the blood vessel irritation of common vein usefulness aqueous injection and toxic reaction etc., and the medicine water solublity is unsatisfactory, poor stability, especially degraded easily takes place and flavescence after liquid drugs injection is sterilized, its quality of long term store and be difficult to safely control etc. all influences its curative effect and clinical use.
Therefore the matrine preparation that definitely needs a kind of stable, efficient, low toxic and side effects, excellent biological compatibility and be easy to prepare.

Sterol such as cholesterol or long-chain (C
14-C
22) alcohol, phosphatidic acid does the cosolubilization agent also optional the adding.If use, be that the general consumption of this class material is 0～1% in Emulsion weight.
Matrine can multiple concentration be sneaked into, and typical concentration is 5mg matrine/ml Emulsion.
The present invention also relates to the preparation method of the stabilized oil-in-water emulsion of matrine on the other hand, promptly with surfactant the oil solution of matrine is distributed to the method for the oil in water emulsion that formation is stable in the water: matrine is dissolved in the oil of a certain amount of ratio to limpid; Be distributed to phospholipid such as Ovum Gallus domesticus Flavus lecithin in the oil or evenly spread in the water, the water alternative comprises glycerol to regulate required permeability (in fact, glycerol can be added to aqueous phase in any moment in preparation process).Under the situation of high-speed stirred water, the oil solution that will contain matrine (with cholesterol if desired) is added in the dispersion to form primary emulsion, and it is refining that primary emulsion is transferred to homogenizer, makes to be suitable for the Emulsion that vein is used, stable, that granularity is little, nontoxic.
The Emulsion of intravenously administrable is the targeted drug carrier, belongs to the novel form of targeting drug delivery system.The characteristics of this dosage form are: particle disperses, be the lipoid microsphere structure, enter to change behind the human body and distributed in the body of medicine carrying thing, main liver the people, spleen, distributed density is higher in the histoorgans such as lung and bone marrow, the lymphsystem directivity is arranged, thereby improve the therapeutic index of medicine, reduce the toxicity of the therapeutic dose and the reduction medicine of medicine, and can regulate body's immunological function.Mainly be in antitumor and anti-infective treatment, to demonstrate obvious superiority.Therefore, in conjunction with many weak points of the existing preparation of aforementioned matrine, and its good oil-soluble, we dissolve in matrine in the oil and finally make stable oil in water emulsion is vein matrine lipomul, its advantage mainly is:
1. targeting: be its most outstanding advantage, contain the lipoid microsphere of matrine in the Emulsion, higher relatively at liver organ pipe distributed density, be easy to be gathered in diseased region with its distinctive characteristic.
2. slow-releasing: the matrine that is wrapped in the Emulsion enters in the blood circulation and is distributed in target site with higher concentration, and slowly continues to discharge from lipoid microsphere, has prolonged action time.
3. high efficiency: reduced administration number of times, brought into play higher curative effect.
4. reduced toxic and side effects and to the zest of blood vessel: matrine is wrapped in the lipoid microsphere, and because of barrier action has significantly reduced blood vessel irritation and inflammatory reaction, said composition is good, the easy thing of degraded of biocompatibility;
5. improved stability of drug: degraded easily takes place in common matrine water injection in preparation, sterilization and long term store process and flavescence is difficult to guarantee drug safety.It is wrapped in the stability that has then obviously improved in the lipoid microsphere in said process.
Trial-produce successfully with the matrine oil in water emulsion for vein, and compare with other preparation of kind, it is easy to prepare, stablize, efficient, hang down its good preparation that meets very much the hepatitis needs really of toxic and side effects, excellent biological compatibility demonstration.
