Problems solved by technology

At present, the clinical treatment methods for ovarian cancer are tumor cytoreductive surgery, chemotherapy and radiotherapy. According to the patient's condition, chemotherapy can be given before and after surgery. Therefore, chemotherapy plays an important role in the treatment of patients with advanced ovarian cancer. However, due to the drug resistance of tumor cells The toxicity and side effects of chemotherapy affect the overall effect of chemotherapy, so the resistance of ovarian cancer patients to chemotherapy drugs has become the biggest obstacle to chemotherapy
[0006] So far, there has been no report on the correlation between citicoline sodium and its pharmaceutical composition and the prevention and treatment of ovarian cancer

Embodiment 1

[0020] Example 1: Compound (I) Separation Preparation and Structure Confirmation

[0021] Separation method: (a) Grind the dried root (2kg) of Polygala, extract with 80% ethanol under heat reflux (15L×3 times), combine the extracts, concentrate until no alcohol smell (3L), and then use petroleum ether (3L×3 times) 3 times), ethyl acetate (3L × 3 times) and water-saturated n-butanol (3L × 3 times) were extracted to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; (b) step (a) Use D101 type macroporous resin to remove impurities from the n-butanol extract in (a), first elute with 10% ethanol for 8 column volumes, then use 70% ethanol for 10 column volumes, collect 70% eluate, and depressurize Concentrate to get 70% ethanol elution concentrate; (c) in step (b), 70% ethanol elution concentrate is separated with normal phase silica gel, and the volume ratio is 60:1 (10 column volumes), 30:1 ( 8 column volumes), 15:1 (10 column volumes) and ...

Abstract

The invention discloses a citicoline sodium medicine composition and pharmaceutical application of the citicoline sodium medicine composition to preventing and treating ovarian cancer. The citicoline sodium medicine composition contains citicoline sodium and a natural product compound (I) which is separated from dried roots of radix polygalae and is of a novel structure. Only common effects of preventing and treating the ovarian cancer can be realized when the citicoline sodium and the natural product compound (I) are individually used, but effects of preventing and treating the ovarian cancer can be obviously improved when the citicoline sodium and the natural product compound (I) are used with each other, and accordingly the citicoline sodium medicine composition can be developed to obtain medicines for preventing and treating the ovarian cancer. Compared with the prior art, the citicoline sodium medicine composition and the pharmaceutical application have the advantages of outstanding substantial characteristics and obvious advancement.

Description

technical field [0001] The invention belongs to the field of biomedicine and relates to a new application of citicoline sodium, in particular to a pharmaceutical composition of citicoline sodium and its medical application for preventing and treating ovarian cancer. Background technique [0002] Citicoline sodium is used for disturbance of consciousness after acute craniocerebral trauma and brain surgery. It can gradually restore the function of limbs to hemiplegia caused by cerebral apoplexy. It can also be used for function and consciousness disturbance caused by other acute injuries of the central nervous system. in ischemic cerebrovascular disease and vascular dementia. [0003] Citicoline sodium can promote brain substance metabolism and improve cerebral circulation by reducing cerebrovascular resistance and increasing cerebral blood flow. It can also enhance the function of the ascending reticular activation system of the brain stem, enhance the function of the verteb...
