Description

The Chinese medicine extract and the purposes that contain the dammarane type four-ring triterpenoid saponins
Technical field
The invention belongs to Chinese medicine extract, relate to the dammarane type four-ring triterpenoid saponins extract that extracts from the Chinese medicine Radix Notoginseng, this extract and anthracene ring antitumor medicinal are united when using, and can alleviate its cardiac toxicity, and can not reduce the latter's antitumor curative effect.
Technical background
Since nineteen fifty-seven was isolated first anthracene nucleus kind anti-cancer drugs daunorubicin (Daunorubicin), the anthracene nucleus kind anti-cancer drugs had become a widely used clinically based chemotherapy medicine.(ADM) after entering clinical trial the seventies, distinguishing feature, especially effective to hypoxic tumor cells such as antitumor spectra is wide because of having, clinical efficacy is good has become the representative medicine of anthracene nucleus kind anti-cancer drugs to amycin for Doxorubicin.DXR, Adriamycin.ADM is effective to kinds of tumors, comprising: hematological system tumor, malignant lymphoma, breast carcinoma, bladder cancer, pulmonary carcinoma, ovarian cancer, cervical cancer, carcinoma of testis, tumor of head and neck and bone and soft tissue tumor etc.ADM is cheap, and curative effect-expense is one of current antitumor drug commonly used clinically than higher.But because restriction, especially the dose accumulation cardiac toxicity of its main toxicity cardiac toxicity have seriously limited its extensive and life-time service clinically.
In order to solve the cardiac toxicity problem of anthracene nucleus kind anti-cancer drugs, the various countries scholar has proposed different countermeasures, comprises the analog of seeking high-efficiency low-toxicity and uses the myocardial preservation medicine.
At present, found multiple amycin analog.Two analogs that have been used widely clinically be pirarubicin [Perarubicin, Pirarubicin, (2R)-4-O-Tetrahydropyranyladriamycin, THP] and epirubicin (Epirubicin, EPI).THP in 1979 by discoveries such as Japanese scholar Umezawa, be the Pentamethylene oxide. derivatives of ADM, added THP trtrahydropyranyl in the 4 three-dimensional positions of ADM.EPI is the isomer of ADM.The cardiac toxicity of these 2 kinds of medicines will be lower than amycin.But the bone marrow toxicity of Perarubicin is more much higher than amycin, and epirubicin still has cardiac toxicity, has certain bone marrow toxicity simultaneously, and price is higher, therefore can not replace amycin fully.
Myocardial preservation medicine commonly used does not have significant curative effect to the cardiac toxicity that amycin causes.Recently, FDA has ratified dexrazoxane (dexrazoxane) can effectively prevent the cardiac toxicity that anthracene ring antitumor medicinal such as amycin etc. bring out as chemical protective agent, and does not influence the anti-tumor activity of chemotherapeutics.It combines with iron ion by be hydrolyzed into chelating agen in cell, disturbs Fe 3+The formation of-anthracycline drug chelate, and then reduced the oxygen-derived free radicals generation.In addition, dexrazoxane has also suppressed the peroxidating of this class chelate to cardiolipin, thereby heart is had unique protective effect.This medicine now in North America and European countries' listing, is mainly used in the advanced breast cancer patient.These product have the protective agent of preventive effect as unique listing to anthracene nucleus antineoplastic chemical drugs cardiac toxicity, have obtained significant curative effect clinically.But the dosage of dexrazoxane is very big, normally 10 of amycin times, and certain nephrotoxicity is arranged.Show that from clinical information if adopt dexrazoxane and amycin to merge the scheme of administration, patient's financial burden will improve 5-10 doubly.Therefore, the new anti-amycin cardiac toxicity medicine of exploitation has realistic meaning.
The mechanism that amycin causes cardiac toxicity is not clear and definite fully yet.But existing several hypothesis obtain the support of experimental evidence: 1) amycin is induced and is produced a large amount of oxygen-derived free radicals, and excessive oxygen-derived free radicals causes the damage and the death (or apoptosis) of cell function; 2) amycin is accumulated in the mitochondrion, causes electron transport chain to take off coupling, and the cellular energy dysbolismus is also therefore downright bad; 3) amycin causes the intracellular calcium overload, causes apoptosis; 4) amycin causes a large amount of releases of NO excessive secretion and ultra-oxygen anion free radical, causes proteinic nitration to modify, and causes protein function to destroy.
Arasaponin derives from panax araliaceae plant (Panax notoginseng (Burk.) F.H.Chen), has pharmacologically active widely.A large amount of experimentation and clinical practices show; arasaponin itself does not have or only has faint antioxidant activity; but the heart and injury that oxidative stress causes is had protective effect, especially reperfusion injury of ischemic heart desease, heart etc. is had definite curative effect.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, it is the Chinese medicine extract that contains dammarane type four-ring triterpenoid saponins compounds that a kind of main active is provided, derive from panax araliaceae plant (Panaxnotoginseng (Burk.) F.H.Chen), contain Panax Notoginseng saponin R at least 1, the ginsenoside Rg 1, Rb 1, Re and Rd, its content (HPLC method mensuration) is 45~95% (w/w).These compositions also can extract from other plant and obtain, and perhaps the approach by chemosynthesis or biotransformation obtains.
Chinese medicine extract provided by the invention can add in the other medicines, is combined into new chemicotherapy ancillary drug.
Another object of the present invention provides the Chinese medicine extract that contains dammarane type four-ring triterpenoid saponins compounds and alleviates application in the medicine of anthracene ring antitumor medicinal cardiac toxicity in preparation.The antagonism anthracene ring antitumor medicinal cardiac toxicity that the present invention uses Chinese medicine extract has carried out in the body, experiment in vitro studies have shown that; arasaponin also has significant protection effect to the inductive heart and injury of amycin, but does not weaken the antitumous effect of anthracene ring antitumor medicinal (as amycin).Can be used as prevention, alleviate anthracene nucleus medicament cardiac toxicity new type natural preparation.
Innovation part of the present invention is: 1. arasaponin compounds, belong to the dammarane type four-ring triterpenoid saponins, the activity that does not have tangible antioxidation or removing free radical, there is not tangible calcium ion complexing yet, but can bring into play the effect of anti-amycin cardiac toxicity, mean that its mechanism of action is novel; Reported first of the present invention a kind of Chinese medicinal plant extract can alleviate the cardiac toxicity of amycin, and do not influence the anti-tumor activity of amycin, still do not have any Chinese medicine extract before this and be in the news and have related activity; 3. although the physiologically active of arasaponin has obtained extensive studies, the someone reports the activity of arasaponin aspect anti-amycin cardiac toxicity as yet, and the present invention will further enlarge the clinical practice of Radix Notoginseng.In view of Radix Notoginseng and the secular human history of extract thereof, its safety is extensively admitted, and this means that the present invention has bright potential applicability in clinical practice.
