Technical field

The present invention relates to the application of arteannuin in the preparation artitumor multi-medicine-resistant medicine, belong to field of medicaments.

Background technology

Tumor multi-medicine drug-resistant is one of major reason that causes the chemotherapy of tumors failure.Multidrug resistance (multidrug Resistance, MDR) be meant that tumor cell develops immunity to drugs to a kind of antitumor drug in accepting the cancer drug therapy process in, to structure and the diverse antineoplastic agent deposits yields cross-resistance of effect.Cause tumor multi-medicine drug-resistant mechanism complicated, tumor cell can obtain multidrug resistance by different approaches.Think at present, cause MDR mechanism to comprise: 1. be present in the P glycoprotein on the tumor cell membrane, multidrug-associated protein, lung resistance-related protein unconventionality expression; 2. desmoenzyme abnormal changes such as phosphokinase C, DNA topoisomerase II, glutathion (GSH) and glutathione-S-transferase.In addition, the variation of the increase of the synzyme of thymidine (TS), aldehyde dehydrogenase (ALDH) and dihydrofolate reductase (DHFR) also can cause the chemical sproof generation of cell; 3. natural death of cerebral cells (Apoptosis) gene and cytokine change.4. DNA repairs unusual; 5. organ microenvironment and other factors etc.

In recent years, along with to the deepening continuously of tumor drug resistance Mechanism Study, had been found that some multidrug resistance reversing agent and active component thereof.Mainly contain: 1. calcium channel blocker, as be verapamil; 2. immunosuppressant is as Ciclosporin A; 3. glutathione transferase (GST) and TOP isomerase II inhibitor; 4. hormone and hormone antagonist compounds; 5. kinases inhibitor; 6. DNA repairs related enzyme activity inhibitor etc.But what can enter clinical research has only only a fews such as isoptin, cyclosporin A, SDZPSC833, zitazonium, and clinical reversing effect is unsatisfactory.It mainly contains following reason: 1. toxic and side effects has limited dosage; 2. the clinical drug-resistant of multimachine system participation formation makes the single inversion agent of action target spot be difficult to play a role; 3. biological preparation is unstable in vivo, and the half-life is short, be difficult to affact the target spot position, and side reaction is many.

In the last few years, found that many Chinese medicines and active ingredient of Chinese herbs thereof can reverse multiple drug resistance of tumor, particularly Chinese medicine reversing tumor drug resistance is after the classical mechanism of the MDR of P-gP mediation is generally acknowledged the back and affirmed the reverse effect to MDR such as calcium antagonist isoptin, and the tumor research persons begin the MDR reversal agents that research evaluation effect is strong from the Chinese medicine with calcium channel antagonistic activity consciously, toxicity is little both at home and abroad.Result of study is found: 1. Chinese herb rhubarb Main Ingredients and Appearance emodin/chrysophanic acid can increase the cytotoxicity of antitumor drug under low dosage, and can partly reverse the MDR of tumor cell; 2. Tetrandrine, Dauricine, liensinine, left-handed tetrahydrochysene Ma Ting and ginsenoside Rb1's reverse multiple drug resistance of tumor effect is obvious, and reversing multiple and be 8.2-13.0 and matrine, aconitine has in various degree reverse effect to the property of medicine of drug-resistant cell strain; 3. Chinese medicine Radix Stephaniae Tetrandrae extract tetrandrine can suppress the MDR characteristic of mdr cell to a certain extent; 4. the main active ingredient Peimine and the Peiminine that reduce phlegm in the Chinese medicine Bulbus Fritillariae Uninbracteatae show unique characteristics aspect reverse multiple drug resistance of tumor, its chemical constitution is under the jurisdiction of the cevine Alkaloid of different steroidal alkaloid, be different from calcium ion antagonist, immunosuppressant and other existing reversal agent of drug resistance fully, and can act on the tumor cell of resistance mechanism difference (P-gP or MDR), potential applicability in clinical practice is arranged very much.The Chinese traditional compound medicine R3 of the class of 5. regulating the flow of vital energy Chinese medicine Rhizoma Corydalis, Fructus Psoraleae extractant, Chinese medicinal formulae (forming) by drug for invigorating blood circulation and eliminating stasis such as Rhizoma Chuanxiong, Rhizoma Curcumae, Caulis Spatholobis but extracting solution R1 etc. have 6. Bulbus Fritillariae Thunbergii powder reversing acute leukemia multidrug resistance of reversing drug resistance effect.But these medicine/active ingredients or stay in laboratory stage, or the back toxicity of purifying is bigger, or it is lower and be difficult to realize the reversing drug resistance effect to reverse multiple.

Herba Artemisiae Annuae is clinical conventional Chinese medicine, and bitter in the mouth suffering, cold in nature is returned liver, gallbladder meridian.Have heat clearing away, expelling summer-heat, remove steam, the effect of preventing the attack (or recurrence) of malaria.Diseases such as pathogenic summer-heat heatings, fever due to yin deficiency, night fever abating at dawn, hectic fever due to YIN-deficiency consumptive fever, malaria cold and heat, jaundice due to damp-heat are treated in normal clinically and other drug matchings.Its Main Ingredients and Appearance is an arteannuin, and arteannuin also is its antimalarial main active ingredient simultaneously.Arteannuin and derivant thereof are the specially good effect new antimalarial agents of China's independent development exploitation, it has advantage quick, safe and efficient, no Drug resistance, more because its structure is special, pharmacological action is extensive, enjoys domestic and international the world of medicine to pay close attention to having potential tempting prospect aspect the multiple diseases such as anti-curing oncoma, acquired immune deficiency syndrome (AIDS).Arteannuin is the ester compounds that contains the sesquiterpene of a peroxide bridge, because the uniqueness of its structure, and makes its malaria mechanism of action and known antimalarial far different.Experimentation shows, arteannuin mainly is by damaging plasmodial film system to the plasmodium scavenging action, and tumor multi-medicine drug-resistant produces important mechanisms and tumor cell membrane abnormal protein have substantial connection, this just enlightens the antimalarial pharmacological mechanism of artemisin, may be to the tumor multi-medicine drug-resistant treatment effectively.
