Abstract
The invention relates to the technical field of medicines, in particular to a composition of marsdenia tenacissima glycoside H and doxorubicin and application thereof, wherein the molar concentration ratio of the marsdenia tenacissima glycoside H to the doxorubicin is as follows: marsdenia tenacissima glycoside H: doxorubicin 1: 2. The invention takes human lung cancer cell A549, gastric cancer cell SGC-7901 and breast cancer cell MCF-7 as in-vitro experimental models to observe the cell proliferation inhibition effect of the combined drug of marsdenia tenacissima glycoside H and doxorubicin, and the experimental results show that: compared with a control group (single drug), the combined drug group has obvious inhibition on cell proliferation, and the synergistic effect of the two can obviously enhance the effect of the chemotherapeutic drug in tumor treatment, thereby having the prospect of developing into clinical combined drug.
Description
Technical Field
The invention relates to the technical field of medicines, in particular to a composition of marsdenia tenacissima glycoside H and doxorubicin and application thereof.
Background
Malignant tumor-cancer has become one of the main diseases that are common and seriously threaten human life and quality of life. In recent years, with the development of economic society, the life level of people is increasing, but the morbidity and mortality of cancer are increasing.
The currently clinically used western medicines for treating tumors have large toxic and side effects, cause great damage to the bodies of tumor patients during treatment, and also have the problems of reduced sensitivity of malignant tumor cells to the western medicines and the like. The disease is more difficult to treat, and the life quality of the patient is reduced.
Apoptosis refers to a process that factors inside and outside a body trigger a death program prestored in a cell, the death program of the cell is automatically started under the control of genes, and the life process is orderly ended, namely programmed cell death. The normal organism utilizes apoptosis to eliminate redundant, aged and damaged cells so as to keep the internal environment balance of the organism and maintain normal physiological activities. Imbalance of apoptosis may cause various diseases such as cancer and autoimmune diseases. The sensitivity of tumor cells to chemotherapeutic drugs is reduced, so that chemotherapy is difficult to progress well, and chemotherapy fails, and therefore, the research and application of mechanisms for improving the sensitivity of tumor cells to chemotherapeutic drugs is urgent. The combined medication refers to the simultaneous or sequential application of two or more drugs for achieving the purpose of treatment, and the result is mainly to increase the curative effect of the drugs or to reduce the toxic and side effects of the drugs. Research proves that the combination of the traditional Chinese medicine monomer and the chemotherapeutic drug can obviously reduce the dosage of the chemotherapeutic drug and reduce the adverse reaction of patients. Aiming at the defects of the prior art, the invention firstly proposes the combination of the marsdenia tenacissima glycoside H and the doxorubicin for resisting cancer, and the experimental result shows that the two have synergistic effect, so that the increment rate of malignant tumors can be greatly reduced, and the sensitivity of the malignant tumors to chemotherapeutic drugs can be greatly improved. The composition of the marsdenia tenacissima H and the doxorubicin and the application thereof are not reported at present.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a composition of marsdenin H and doxorubicin and application thereof.
In order to achieve the purpose, the invention adopts the technical scheme that:
in a first aspect, the invention provides a marsdenin H combined doxorubicin composition, wherein the molar concentration ratio of the marsdenin H to the doxorubicin is as follows: marsdenia tenacissima glycoside H: and (2-4) doxorubicin is 1.
Preferably, the molar concentration ratio of the marsdenia tenacissima H to the doxorubicin is as follows: marsdenia tenacissima glycoside H: and (2-3) doxorubicin is 1.
Preferably, the molar concentration ratio of the marsdenia tenacissima H to the doxorubicin is as follows: marsdenia tenacissima glycoside H: doxorubicin 1: 2.
Further, the composition comprises a pharmaceutically acceptable carrier, and the pharmaceutically acceptable carrier and the marsdenin H are processed together.
Further, the dosage form of the marsdenia tenacissima H comprises injection, tablets, capsules or granules.
In a second aspect, the present invention provides a method for preparing the composition, comprising the step of weighing the raw materials according to molar concentration ratios.
In a third aspect, the present invention provides the use of a composition as described above for the preparation of a medicament for the treatment of a malignant tumor.
Preferably, the malignant tumor comprises human lung cancer malignant tumor, human gastric cancer malignant tumor and human breast cancer malignant tumor.
Furthermore, the composition can inhibit the proliferation of malignant tumor cells, promote the apoptosis of the malignant tumor cells, reduce the dosage of the doxorubicin and improve the sensitivity of malignant tumor to the doxorubicin.
Term(s) for
As used herein, an ingredient of the term "pharmaceutically acceptable" is one that is suitable for use in humans and/or animals without undue adverse side effects (such as toxicity, irritation, and allergic response), i.e., at a reasonable benefit/risk ratio.
As used herein, the term "pharmaceutically acceptable carrier" refers to a carrier for administration of a therapeutic agent, including various excipients and diluents and the like. The term refers to such pharmaceutical carriers: they are not essential active ingredients per se and are not unduly toxic after administration. Suitable carriers are well known to those of ordinary skill in the art. A thorough discussion of pharmaceutically acceptable excipients can be found in Remington's Pharmaceutical Sciences (mackpub.co., n.j.1991). Pharmaceutically acceptable carriers in the compositions may comprise liquids such as water, saline, glycerol and ethanol. In addition, auxiliary substances such as emulsifiers, fillers, binders, wetting agents, disintegrants, absorption enhancers, flavoring agents, colorants, cosolvents and the like may also be present in these carriers.

Discussion 4
Doxorubicin is a first-line chemotherapeutic drug for the clinical treatment of gastric cancer, however, the reduction of the sensitivity of tumor cells deteriorates the therapeutic effect. Clinical data indicate that combination therapy can improve efficacy compared to traditional chemotherapy alone. Therefore, the search for natural ingredients which can be synergistically used with conventional chemotherapeutic drugs has great clinical significance for the treatment of colorectal cancer.
In the invention, the combination of marsdenia tenacissima H and doxorubicin is adopted, and in-vitro experiments prove that the drug can effectively inhibit the proliferation of lung cancer A549 cells, gastric cancer SGC-7901 cells and breast cancer MCF7 cells, so that the sensitivity of cancer cells to chemotherapeutic drugs is enhanced, and the apoptosis of tumor cells is promoted.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and additions can be made without departing from the principle of the present invention, and these should also be considered as the protection scope of the present invention.
