Abstract

The invention provides application of timosaponin I in preparation of anti-human ovarian cancer drugs, and belongs to the technical field of new medical application of the timosaponin I. The molecular formula of the timosaponin I is C39H66O14, and the chemical structural formula of the timosaponin I is shown in the specification. The timosaponin I can effectively inhibit expression of mRNA of SHH signal channel related target genes and protein GLI1 and SUFU in human ovarian cancer cells SKOV3; the timosaponin I can effectively inhibit proliferation, epithelial-mesenchymal transition (EMT), migration and invasion of SKOV3 cells, and it is indicated that the timosaponin I is expected to be developed into an effective component of the medicine for resisting the human ovarian cancer. In addition, the medicine can be prepared into different preparation forms according to the requirements of patients, is convenient for the patients to take, and has better development and application prospects.

Description

technical field [0001] The invention belongs to the technical field of new medical applications of timosaponin I, and in particular relates to the application of timosaponin I in the preparation of anti-human ovarian cancer drugs. Background technique [0002] Ovarian cancer is the most common malignant tumor in women over the age of 40, second only to breast cancer, and the deadliest gynecological cancer. According to the 2020 survey, there are approximately 313,959 new cases of ovarian cancer and 207,252 deaths worldwide each year. Due to the relatively hidden location of the ovary and the lack of effective screening methods, the vast majority of ovarian cancers have already metastasized when diagnosed. At present, the treatment mode of ovarian cancer is mainly based on tumor reduction surgery and chemotherapy based on platinum drugs. Ovarian cancer patients often go through a cycle of surgery-chemotherapy-relapse-chemotherapy-relapse-re-chemotherapy, during which the sen...
