Embodiment 1

[0051] Example 1: Tipranavir can effectively kill human gastric cancer stem cells at a low concentration, and it is time- and concentration-dependent.

[0052] Two lines of gastric cancer stem cells (denoted as GCSC1 and GCSC2) derived from different gastric cancer patients were taken, and the cell concentrations were both (1×10 5 cells / mL, 100μl), inoculated in 96-well plate, three replicate wells in each group, treated GCSC1 with different concentrations of Tipranavir (0uM, 0.5uM, 1.0uM, 2.5uM, 5.0uM, 10uM, 20uM, 40uM, 100uM) And GCSC2 cells 24hr, 48hr, 72hr, DMSO as a control. CCK-8 was added to measure the absorbance value (A450) at a wavelength of 450 nm, and the cell growth curves of each group were drawn. Detect the killing effect of Tipranavir on gastric cancer stem cells (GCSC1 and GCSC2), and calculate its IC 50 , see the result figure 1 ( figure 1 , cell viability cell activity; concentration concentration).

[0053] The results showed that Tipranavir could eff...

Embodiment 2

[0054] Example 2: The effect of Tipranavir on killing gastric cancer stem cells is significantly better than that of the existing first-line drug combined with 5-FU and cisplatin.

[0055] Two lines of gastric cancer stem cells (denoted as GCSC1 and GCSC2) derived from different gastric cancer patients (1×10 5 cells / mL, 100 μl) were inoculated in 96-well plates, and each group had three replicate wells, and GCSC1 and GCSC2 cells were treated with Tipranavir (10uM) and 5-FU+cisplatin (5-FU: 2.5μM; cisplatin: 4μM) for 72hr, respectively, DMSO served as a control. CCK-8 was added to measure the absorbance value (A450) at a wavelength of 450 nm, and the cell growth curves of each group were drawn. Comparison of the killing effects of Tipranavir and 5-FU+cisplatin on gastric cancer stem cells (GCSC1 and GCSC2). see results figure 2 ( figure 2 , cell viability cell activity).

[0056] The results showed that the effect of Tipranavir on killing gastric cancer stem cells was si...

Embodiment 3

[0057] Example 3: Tipranavir can effectively kill gastric cancer cells, and its effect is also significantly better than the combination of 5-FU and cisplatin, and has no toxic side effects on normal gastric epithelial cells, while the combination of 5-FU and cisplatin has no effect on normal gastric epithelial cells. Cell toxicity.

[0058] Four gastric cancer cell lines (AGS, HGC-27, MGC-803, BGC-823) and normal gastric epithelial cell line (GES-1) (1×10 5 cells / mL, 100 μl) were inoculated in 96-well plates, and each group had three replicate wells, and the cells of each strain were treated with Tipranavir (10uM) and 5-FU+cisplatin (5-FU: 2.5μM; cisplatin: 4μM) for 72hr, DMSO as comparison. CCK-8 was added to measure the absorbance value (A450) at a wavelength of 450 nm, and the cell growth curves of each group were drawn. To compare the killing effects and side effects of Tipranavir and 5-FU+cisplatin on gastric cancer cells (AGS, HGC-27, MGC-803, BGC-823) and normal gast...

Abstract

The invention discloses application of Tipranavir in preparation of a cancer treatment drug for killing tumor stem cells and tumor cells, and relates to the technical field of medicines. The inventionfurther discloses a cancer treatment drug. The drug can kill the tumor stem cells and the tumor cells; the drug takes the Tipranavir as a main active component and contains a pharmaceutically acceptable carrier. The invention provides the Tipranavir for the first time, and the Tipranavir can be used for preparing the anti-cancer drug for killing the tumor stem cells and the tumor cells; the anti-gastric cancer effect of the Tipranavir is obviously better than that of an existing gastric cancer first-line treatment drug (5-FU and cisplatin are combined); the Tipranavir has no obvious toxic side effect and the toxic side effect is obviously smaller than that of the gastric cancer first-line treatment drug (5-FU and cisplatin are combined); a novel drug and scheme are provided for tumor treatment of targeted tumor stem cells and healing of tumors; and the Tipranavir has important meanings on improvement of the tumor treatment effect and improvement of the living quality of patients.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to the application of Tipranavir in the preparation of cancer therapeutic drugs for killing tumor stem cells and tumor cells. Background technique [0002] Malignant tumors are diseases with high morbidity and high mortality that seriously endanger human health. For example, gastric cancer (GC) is the most common malignant tumor of the digestive system, its incidence rate ranks fifth among all malignant tumors in the world, and its mortality rate ranks third among the causes of malignant tumors. my country is a high-incidence area of ​​gastric cancer, with high morbidity and mortality, both ranking second in malignant tumors. The principle of gastric cancer treatment is comprehensive treatment based on surgical treatment. In my country, the early diagnosis rate of gastric cancer is still relatively low. Most patients are diagnosed with advanced tumors and lose the chance of surgi...
