[0097] The present disclosure will be now further explained with respect to the examples:

Example 1 the Inhibitory Effect of Sotagliflozin on Tumor Cells

[0098] Prostate cancer DU145 cells, breast cancer MCF-7 cells, esophageal cancer KYSE30 cells, gastric cancer HGC-27 cells, cholangiocarcinoma RBE cells, ovarian cancer SKOV3 cells, and cervical cancer Hela cells were used to verify the inhibitory effect of Sotagliflozin on tumor cells. After growing to 80% density, the cells were trypsinized, passaged and plated in a 96-well plate with 5000 cells per well. After 24 hours, the medium was replaced with a medium containing the corresponding concentration of drug. After 48 hours, the absorbance at each concentration was detected by the MTT method.

[0099] The experiment included the following groups:

[0100] Control group: cells were cultured in normal culture medium without drug added.

[0101] Sotagliflozin test group: cells were treated by adding Sotagliflozin at different concentration to each culture medium.

[0102] After incubation, the cell growth inhibition rate was calculated by dividing the absorbance value at each concentration by the absorbance value of the control group. The calculated IC.sub.50 values of Sotagliflozin on various tumor cells are shown in FIG. 1-a to FIG. 1-g. In the figures, the concentration of Sotagliflozin is taken as the abscissa and the cell growth inhibition rate is taken as the ordinate. The results show that Sotagliflozin has a certain inhibitory effect on various tumor cells.

Example 2 Sotagliflozin Combined with Gefitinib

1. Determination of the Safe Concentration of Sotagliflozin

[0103] Sotagliflozin was purchased from Selleck Chemicals for growth inhibition test of cancer cell in vitro. Initially, test using normal human umbilical cord epithelial cells showed that Sotagliflozin produced great cytotoxicity at a concentration higher than 80 μM, and mainly exhibited cell growth inhibition effect at a concentration lower than 8 μM. Therefore, the concentrations of Sotagliflozin used in the subsequent compositions of this experiment were all lower than 80 μM to avoid affecting normal cells.

2. The Inhibitory Effect of Combination Administration on Tumor Cells

[0104] According to the tissue distribution characteristics of EGFR and SGLT1/2, the targets of Gefitinib and Sotagliflozin, the followings cells were selected for experimental verification: lung cancer cell line A549; colorectal cancer cell line LoVo, HT29, SW620, HCT116; cervical cancer HeLa; ovarian cancer SKOV3; gastric cancer HGC27; cholangiocarcinoma RBE; esophageal cancer KYSE30, and the like. After growing to 80% density, the cells were trypsinized, passaged and plated in a 96-well plate with 5000 cells per well. After 24 hours, the medium was replaced with a medium containing the corresponding concentration of drug. After 48 hours, the absorbance at each concentration was detected by the MTT method.

[0105] The experiment included the following groups:

[0106] Control group: cells were cultured in normal culture medium without drug added.

[0107] Gefitinib test group: cells were treated by adding Gefitinib alone at 4 different concentration, 5 μM, 10 μM, 20 μM, 30 μM, respectively, to the culture medium.

[0108] Gefitinib+Sotagliflozin combination test group: cells were treated by adding both Sotagliflozin (20 μM) and Gefitinib at 4 different concentration, 5 μM, 10 μM, 20 μM and 30 μM, respectively, to the culture medium.

[0109] After incubation, the cell growth inhibition rate was calculated by dividing the absorbance value at each concentration by the absorbance value of the control group. The results are shown in FIG. 2-a to FIG. 2-e. In the figures, the concentration of Gefitinib is taken as the abscissa and the cell growth inhibition rate is taken as the ordinate. The results showed that the inhibitory effect of Gefitinib alone on tumor cells is limited, and the combination of the two drugs is beneficial to improve the tumor inhibitory effect.

3. Determination of IC.SUB.50 .Value of Combination Administration

[0110] Lung cancer cell line A549 was used as an example to verify the IC.sub.50 value of the Gefitinib+Sotagliflozin combination. The experiment included the following groups:

[0111] Gefitinib test group (FIG. 2-a-1): cells were treated by adding Gefitinib alone at 6 different concentrations, 0M, 10M, 20 μM, 30 μM, 4 μM and 5 μM respectively, to the culture medium, and cell survival rate was measured after 1 h of incubation. The results showed that the IC.sub.50 value of Gefitinib on A549 cells was 24.4 μM.

[0112] Sotagliflozin test group (FIG. 2-a-2): cells were treated by adding Sotagliflozin alone at 6 different concentrations, 0 μM, 10 μM, 30 μM, 40 μM, 5 μM and 6 μM respectively, to the culture medium, and cell survival rate was measured after 1 h of incubation. The results showed that the IC.sub.50 value of Sotagliflozin on A549 cells was 73.0 μM.

[0113] Gefitinib+Sotagliflozin combination test group 1 (FIG. 2-a-3): cells were treated by adding both Sotagliflozin (10 μM) and Gefitinib at 6 different concentrations, 0 μM, 10 μM, 20 μM, 30 μM, 5 μM and 60 μM respectively, to the culture medium, and cell survival rate was measured after 1 h of incubation. The results showed that the IC.sub.50 value of the test group to on A549 cells was 17.03 μM.

[0114] Gefitinib+Sotagliflozin combination test group 2 (FIG. 2-a-4): cells were treated by adding both Sotagliflozin (20 μM) and Gefitinib at 5 different concentrations, 0 μM,  μM, 20 μM, 30 μM and 4 μM, respectively, to the culture medium, and cell survival rate was measured after 2 h of incubation. The results showed that the IC.sub.50 value of the test group to on A549 cells was 12.71 μM.

[0115] Gefitinib+Sotagliflozin combination test group 3 (FIG. 2-a-5): cells were treated by adding both Sotagliflozin (30 μM) and Gefitinib at 6 different concentrations, 0M, 10 μM, 20 μM, 30 μM, 4 μM and 50 μM respectively, to the culture medium, and cell survival rate was measured after 1 h of incubation. The results showed that the IC.sub.50 value of the test group to on A549 cells was 9.318 μM.

[0116] The results showed that with the combination of Sotagliflozin and Gefitinib, the inhibitory effect of Gefitinib on A549 cells was significantly enhanced, and the IC.sub.50 was reduced to less than half of that of the single agent. Therefore, the effect of the combination in the safe concentration range of Sotagliflozin is better than the effect of each single agent. The verification results of other cell lines are shown in the figures (2f-2j). It is worth mentioning that the ability of Sotagliflozin in the combination to enhance the efficacy of EGFR-targeting TKI drugs is not limited to a single drug of Gefitinib. In FIG. 2k and FIG. 2l, the present disclosure takes A549 cells as an example to further verify the other two inhibitors of EGFR, Afatinib and Erlotinib, and the results showed that the addition of Sotagliflozin at an a safe dose can effectively reduce a IC.sub.50 values of Afatinib and Erlotinib.

Example 3 Sotagliflozin Combined with Gefitinib Reverses the Resistance of Tumor Cells to Gefitinib

1. Screening of Gefitinib-Resistant Cell Lines.

[0117] After knowing that the combination of Gefitinib and Sotagliflozin significantly enhanced the effectiveness of Gefitinib from example 1, the present disclosure continues to explore whether the combination of the two drugs can reverse the resistance of tumor cells to Gefitinib. Gefitinib-resistant cells can be obtained by long-term culturing of A549 cells with a medium containing Gefitinib at increasing concentrations. After 5 months of screening, the present disclosure obtained A549 gefitinib-resistant cell line that can survive in 60 μM gefitinib for a long time.

2. Sotagliflozin Combined with Gefitinib Reverses the Resistance of Tumor Cells to Gefitinib

[0118] The Gefitinib-resistant cell line obtained by the present disclosure can be effectively killed by adding 30 μM Gefitinib and Sotagliflozin composition. It shows that the combination of Sotagliflozin and Gefitinib reverses the resistance of tumor cells to Gefitinib. The results are shown in FIG. 3.

Example 4 Sotagliflozin Combined with Apatinib

1. The Inhibitory Effect of Combination Administration on Tumor Cells

[0119] After obtaining the effectiveness of Gefitinib in Example 1, the present disclosure further validated another VEGFR-targeting TKI drug, Apatinib. According to the tissue distribution characteristics of VEGFR and SGLT1/2, the targets of Apatinib and Sotagliflozin, the followings cells were selected for experimental verification: liver cancer cell line HepG2; colorectal cancer cell line LoVo, HT29, SW620, SW480; cervical cancer HeLa; ovarian cancer SKOV3; gastric cancer HGC27; cholangiocarcinoma RBE; esophageal cancer KYSE3, and the like. After growing to 80% density, the cells were trypsinized, passaged and plated in a 96-well plate with 5000 cells per well. After 24 hours, the medium was replaced with a medium containing the corresponding concentration of Apatinib, Sotagliflozin, or the combination of Apatinib and Sotagliflozin. After 48 hours, the absorbance at each concentration was detected by the MTT method.

[0120] The experiment included the following groups:

[0121] Control group: cells were cultured in normal culture medium without drug added.

[0122] Apatinib test group: cells were treated by adding Apatinib alone at 4 different concentrations, 5 μM, 10 μM, 20 μM, 30 μM, respectively, to the culture medium.

[0123] Apatinib+Sotagliflozin combination test group: cells were treated by adding both Sotagliflozin (20 μM) and Apatinib at 4 different concentrations, 5μM, 10 μM, 20 μM and 30 μM, respectively, to the culture medium.

[0124] The cell growth inhibition rate was calculated by dividing the absorbance value at each concentration by the absorbance value of the control group. The results are shown in FIG. 4-a-1 to FIG. 4-a-5. In the figures, the concentration of Apatinib is taken as the abscissa and the cell growth inhibition rate is taken as the ordinate. The results show that the inhibitory effect of Apatinib alone on tumor cells is limited, and the combination of the two drugs is beneficial to improve the tumor inhibitory effect.

2. Determination of IC.SUB.50 .Value of Combination Administration

[0125] 2.1. Liver Cancer Cell Line HepG2 was Used as an Example to Verify the IC.sub.50 Value of the Apatinib+Sotagliflozin Combination. The Experiment Included the Following Groups:

[0126] Apatinib test group (FIG. 4-b-1): cells were treated by adding Apatinib alone at 6 different concentrations, 0M, 5 μM, 10M, 20 μM, 30 μM and 40 μM, respectively, to the culture medium, and cell survival rate was measured after 2 h of incubation. The results showed that the IC.sub.50 value of Apatinib on HepG2 cells was 46.0 μM.

[0127] Sotagliflozin test group (FIG. 4-b-2): cells were treated by adding Sotagliflozin alone at 7 different concentrations, 0M, 20 μM, 30 μM, 40 μM, 60 μM, 80 μM and 100 μM respectively, to the culture medium, and cell survival rate was measured after 2 h of incubation. The results showed that the IC.sub.50 value of Sotagliflozin on HepG2 cells was 115.7 μm.

[0128] Apatinib+Sotagliflozin combination test group 1 (FIG. 4-b-3): cells were treated by adding both Sotagliflozin (10 μM) and Apatinib at 6 different concentrations, 0 μM, 5 μM, 10 μM, 20 μM, 30 μM and 40 μM respectively, to the culture medium, and cell survival rate was measured after 2 h of incubation. The results showed that the IC.sub.50 value of the test group to on HepG2 cells was 33.3 μM.

[0129] Apatinib+Sotagliflozin combination test group 2 (FIG. 4-b-4): cells were treated by adding both Sotagliflozin (20 μM) and Apatinib at 6 different concentrations, 0 μM, 5 μM, 10 μM, 20 μM, 30 μM and 40 μM respectively, to the culture medium, and cell survival rate was measured after 2 h of incubation. The results showed that the IC.sub.50 value of the test group to on HepG2 cells was 29.6 μM.

[0130] Apatinib+Sotagliflozin combination test group 3 (FIG. 4-b-5): cells were treated by adding both Sotagliflozin (30 μM) and Apatinib at 6 different concentrations, 0 μM, 5 μM, 10 μM, 20 μM, 30 μM and 40 μM respectively, to the culture medium, and cell survival rate was measured after 2 h of incubation. The results showed that the IC.sub.50 value of the test group to on HepG2 cells was 13.13 μM.

[0131] Apatinib+Sotagliflozin combination test group 4 (FIG. 4-b-6): cells were treated by adding both Sotagliflozin (40 μM) and Apatinib at 6 different concentrations, 0M, 5 μM, 10M, 20 μM, 30 μM and 40 μM respectively, to the culture medium, and cell survival rate was measured after 2 h of incubation. The results showed that the IC.sub.50 value of the test group to on HepG2 cells was 10.89 μM.

[0132] These results showed that with the combination of Sotagliflozin and Apatinib, the inhibitory effect of Apatinib on HepG2 cells was significantly enhanced, and the IC.sub.50 was reduced to less than one-fourth of that of the single agent. Therefore, the effect of the combination in the safe concentration range of Sotagliflozin is better than the effect of each single agent. The verification results of other cell lines are shown in the FIGS. (4c-4g). It is worth mentioning that the ability of Sotagliflozin in the combination to enhance the efficacy of VEGFR-targeting TKI drugs is not limited to a single drug of Apatinib. In FIG. 5, the present disclosure further verified another VEGFR inhibitor Lenvatinib in a variety of cell lines, and the results showed that the addition of Sotagliflozin at a safe dose enhanced the inhibitory effect of Lenvatinib on these cell lines.

After 24 hours, the medium was replaced with a medium containing the corresponding concentration of Apatinib, Sotagliflozin, or the combination of Apatinib and Sotagliflozin. After 48 hours, the absorbance at each concentration was detected by the MTT method.

[0136] The experimental method was the same as before, and the incubation time was 1 h. The experiment included a blank control group, namely normal cultured HepG2 cells, in which the concentrations of Sotagliflozin or TKI drugs were both 0, and the survival rate of the blank control group cells was set to 100%. In other groups, the concentration of Sotagliflozin used was mol/L, and the concentrations of TKI drugs are shown in Table 2. The results are shown in the attached Figures:

[0137] The results showed that each combination administration group showed a significantly better inhibitory effect on tumor cells than the single agent control group.

Example 6

[0138] Examples 1 to 4 are all tests at the cell level. In order to further verify the anti-tumor effect in vivo of the diabetes treatment drug Sotagliflozin discovered in the present disclosure and the combination thereof with TKI inhibitor drugs, lung cancer A549 cells and the Ba1bc nude mice from Charles River Laboratories were used in tumor treatment experiments. After growing to the logarithmic phase, A549 cells were collected and resuspended in serum-free DMEM medium to 5×10.sup.7 cells per ml. Each mouse was inoculated with 100 μl of 5×10.sup.6 cells, and the tumor size was measured 19 days later. Mice were grouped according to the tumor size, and the average tumor size in each group was the same. Mice were administered after grouping.

[0139] According to the current recommended daily dose 200-400 mg of Sotagliflozin for diabetic patients, corresponding to 22 mg to 44 mg per kilogram of body weight for mice, we finally chose a dose of 30 mg/kg of Sotagliflozin for oral administration in mice. The dose of Gefitinib was 100 mg per kilogram according to the reported dose for the treatment of A549 xenograft tumor in previous studies. The two drugs were administered by gavage, consistent with the current oral mode in clinical use. The dosing cycle was once every two days. The tumor size was measured every two days. After 40 days of administration, the test was ended, and the tumor was removed and weighed.

[0140] As shown in FIG. 7-a˜FIG. 7-b˜FIG. 7-c, Sotagliflozin alone and Gefitinib alone can inhibit tumor growth (FIG. 7-a˜FIG. 7-b-FIG. 7-c), and the inhibition effect of the combination of Sotagliflozin and Gefitinib on tumors was better than that of the either drug alone. According to the effectiveness evaluation, the tumor growth inhibition rate should be greater than 60%, and the p value should be less than 0.05. The calculated tumor growth inhibition rate and p value of each group are as shown in the above table. Therefore, the administration of Sotagliflozin alone or Gefitinib alone is ineffective, and the administration of the combination of Sotagliflozin and Gefitinib is effective.

[0141] The above are only the preferred embodiments of the present disclosure. It should be pointed out that for those of skilled in the art, various improvements and modifications can be made without departing from the principle of the present disclosure, and these improvements and modifications should also be considered within the scope of the present disclosure.
