Embodiment 3

[0096] A pharmaceutical composition for treating glioma, comprising a therapeutically effective amount of the pharmaceutical composition of Example 1 above and a pharmaceutically acceptable carrier. The pharmaceutically acceptable carrier is selected from one or more of the following: lactose, sucrose, gelatin, agar, pectin, gum arabic, magnesium stearate, stearic acid, lower alkyl ethers of cellulose , Corn Starch, Potato Starch, Gums, Fatty Acids, Glyceryl Monostearate. The daily effective dosage of the pharmaceutical composition (excluding pharmaceutically acceptable carrier) in the above-mentioned Example 1 is 0.001-0.006g / kg human body, and it can be made into the medicine with corresponding content according to the need, and taken according to the doctor's advice.

Abstract

The invention belongs to the technical field of medicine and particularly relates to a pharmaceutical composition for treating glioma.The pharmaceutical composition comprises a component A, a component B, a component C and a component D, wherein the component A is diterpenoids (I) extracted from callicarpa nudiflora, the component B is withanolides (II) extracted from the dried whole herb of asiatic plantain, the component C is triterpenoid saponins echinoside A purchased from the market, and the component D is flavonoids (IV) extracted from the overground part of vervain.In-vitro experiment prove that the pharmaceutical composition can inhibit the human brain malignant glioblastoma U251 cells by inhibiting cell proliferation and inducing cell apoptosis and can be developed into medicine for treating the glioma.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a pharmaceutical composition for treating glioma. Background technique [0002] Glioma, also known as glioma for short, is the most common primary central nervous system tumor, accounting for about half of all primary intracranial tumors. In a broad sense, it refers to all neuroepithelial-derived tumors. In a narrow sense, it refers to tumors derived from various types of glial cells. According to the classification scheme of the World Health Organization (WHO) in 1999, it is divided into astrocytoma, oligobranchoma, ependymoma, mixed glioma, choroid plexus tumor, neuroepithelial tumor of uncertain origin, and neuroepithelial tumor. Neuronal and neuronal glioma, pineal parenchymal tumor, embryonal tumor, neuroblastoma tumor. [0003] At present, the main treatment for glioma is surgery, but the risk of surgery is extremely high. At present, hormone therapy can be...
