Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with specific examples: the application of a kind of myricetin and doxorubicin composition of the present invention in the preparation treatment human breast cancer preparation, it is to use different concentrations of myricetin and doxorubicin Mycin treated MCF-7 cells, and through the following detection and observation:

[0015] MTT colorimetric method was used to detect the inhibition rate of MCF-7 cells and calculate the combination index of the two drugs;

[0016] AO / EB staining was used to observe the morphological changes of MCF-7 cells;

[0017] JC-1 kit detects the influence on its mitochondrial membrane potential;

[0018] Western blotting was used to detect the expression of apoptosis-related proteins in MCF-7 cells;

[0019] Results: When myricetin or doxorubicin was used alone, both inhibited the growth of tumor cells, and the inhibition rate was dose-dependent. At ~80%, the combinat...

Abstract

The invention discloses application of an FUC (fucoxanthin)-ADR (adriamycin) composition in preparing a human breast cancer treatment preparation. In the application, the FUC and the ADR of differentconcentrations are adopted for treating MCF-7 cells, and detection and observation include detecting the inhibition ratio against the MCF-7 cells by MTT colorimetry, and calculating the combination index of the two drugs; observing the morphological change of the MCF-7 cells by AO/EB staining; detecting the influence on mitochondrial membrane potential with a JC-1 kit; detecting the expression ofapoptosis-related protein in the MCF-7 cells by Western blotting; the result shows that the FUC and the ADR can inhibit the growth of tumor cells when applied respectively, and the inhibition ratio shows dose dependence; when the FUC and the ADR are combined, the inhibition ratio is obviously higher than that of single use; when the total inhibition ratio is 50-80%, the combination index (CI) is less than 1, indicating that the two drugs combined generate a relatively strong synergistic effect.

Description

technical field [0001] The present invention relates to the application of myricetin and doxorubicin composition in the preparation of preparations for treating human breast cancer. Background technique [0002] Breast cancer is one of the most common malignant tumors in women, its incidence rate is the highest among female malignant tumors, and its mortality rate is second only to lung cancer. As a representative of anthracyclines, adriamycin (ADR) chemotherapy can effectively improve the survival rate of breast cancer patients and inhibit the recurrence and metastasis of breast cancer. Myricetin (fucoxanthin, FUC), also known as fucoxanthin or fucoxanthin, is a class of natural carotenoids. Many studies have shown that myricetin has a significant inhibitory effect on breast cancer cells. In the clinical treatment of breast cancer, long-term monotherapy with doxorubicin can easily lead to cardiotoxicity of doxorubicin. Nowadays, the research on the combination of anticanc...
