Background

1. Epidemiology of cancer

Non-infectious diseases are the main causes of death in the world, and cancer is the disease with the highest fatality rate among the non-infectious diseases, and brings heavy burden to the social health medical system. Traditional cancer treatment is mainly performed by surgery and radiotherapy, and chemotherapy is mainly performed on advanced cancer. Classical chemotherapy has great side effects due to poor targeting. The occurrence of targeted chemotherapy drugs represented by gleevec greatly reduces the pain of patients caused by chemotherapy. The targeted drug is designed for molecules different from normal cell growth characteristics and expression of cancer cells, such as gleevec specificity, which has good therapeutic effect on constitutively activated tyrosine kinase in chronic myelogenous leukemia (Flynn and gerries, 2020). Another significant feature of cancer cells, unlike normal cells, is an alteration in the metabolic pattern. In order to balance the need for cellular components for rapid proliferation and to maintain the energy supply required for survival, cancer cells prefer to utilize glucose in an aerobic glycolysis fashion, which is called the Warburg effect (Warburg, 1956). Aerobic glycolysis does not sufficiently oxidize glucose to produce ATP, but can produce a large number of intermediate metabolites for DNA and protein synthesis to promote cancer cell proliferation. It is therefore feasible to target the carbohydrate metabolism of tumor cells, thereby achieving the goal of inhibiting cancer cell proliferation (Kroemer and Pouyssegur, 2008).

2. Suggestin and cancer treatment

Glucose uptake by cancer cells from the external environment is mainly achieved by glucose transporters, which are divided into two major families, the GLUT family, which transports along a glucose concentration gradient in a diffusion-assisted manner, and the SGLT family, which transports glucose uptake by co-transport of sodium ions, and which actively transports external glucose to cells for use in an ATP-consuming manner (Navale and parajame, 2016). The two most prominent members of the SGLT family are SGLT1 and SGLT2, SGLT2 is distributed mainly in the anterior end of the proximal convoluted tubule of the kidney to reabsorb more than 97% of the glucose in the raw urine into the blood by active transport, while SGLT1 is distributed mainly in the epithelial cells of the intestinal serosa and distal end of the proximal convoluted tubule of the kidney to absorb the glucose in the intestinal tract by active transport and the remaining approximately 3% of the glucose in the raw urine after absorption by SGLT2 (douminez Rieg and Rieg, 2019). Because of the important roles of SGLT1 and SGLT2 in sugar absorption and reabsorption, it is an ideal target for the treatment of diabetes. Currently, the empagliflozin targeting SGLT2, canagliflozin and dapagliflozin show good treatment effects when clinically used for treating type II diabetes, and also have the curative effect of reducing cardiovascular diseases. Miglityn alone targeted SGLT1 has entered the clinical study stage. Sogeletin targeting both SGLT1 and SGLT2 was approved for marketing in the european union.

TKI and TKI resistance of cancer

Receptor Tyrosine Kinases (RTKs) are the most common genes in cancer that promote cancer progression, and RTKs, when bound to the corresponding ligands, typically dimerize and catalyze autophosphorylation to initiate a series of downstream signaling cascades that promote cancer cell proliferation (Lemmon and Schlessinger, 2010; Yarden and Pines, 2012). Cancer cells often overexpress RTKs or constitutively activate mutations of RTKs to upregulate RTK activity to promote self-proliferation, and thus targeting RTK activity is a major means for developing anticancer drugs, including small molecule tyrosine kinase activity inhibitors (TKIs) targeting the ATP-binding pocket of RTKs, and targeting ligand-bound mabs and the like (Thomas and Weihua, 2019). The successful development of TKI, which effectively prolongs the disease-free progression survival of patients with over-expressed or constitutively activated RTK, significantly improves the quality of life of the patients, and most TKI are first-line drugs in the corresponding cancer field at present, however, patients who respond well to treatment with TKI even though they are naturally resistant to TKI develop acquired resistance within a treatment period of about one year (Camdge et al; Cortot and Janne, 2014). Summary the reasons for drug resistance are mainly divided into pharmacological resistance and biological resistance, pharmacological resistance is mostly caused by drug interaction in the body and drug concentration around cancer cells cannot be achieved, cancer cells may still be sensitive to drugs, while biological resistance is caused by cancer heterogeneity, drug resistance mutation caused by drug selection pressure, and alternative activation of alternative signal pathways (Minuti, g., a et al). Biological resistance is the main reason for TKI class drug resistance. Against cancer cells

The mechanism of acquired resistance, researchers have devised a number of approaches to overcome cancer resistance, including the development of newer inhibitors for the second, third, etc. generation, against conventional resistance mutations, in combination with radiation or chemotherapy after resistance, and with new targeted drugs. To date, even third-generation inhibitors have acquired resistance, and radiotherapy and chemotherapy have received little benefit. Overcoming resistance in combination with other targeted drugs is the primary choice.

TABLE 1 drugs and their English names

The invention is further illustrated by the following examples:

example 1 combination of Soxhlet with gefitinib

1. Sogelliflozin safety concentration determination

Killing effect of gefitinib on lung cancer A549 cells cultured in a sugar-free culture medium and a sugar-containing culture medium; after 48 hours of treatment of a549 cells with 20uM gefitinib, trypan blue staining was used to distinguish live cells from dead cells, which were stained blue with trypan blue, and the results are shown in fig. 1. According to the earlier findings illustrated in FIG. 1, the in vitro inhibition of cancer cell growth of suggestin purchased from Selleck inhibitors was tested by first testing suggestin using normal human umbilical epithelial cells at concentrations above 80 μ M for significant cytotoxicity, and below 80 μ M for substantial inhibition of cell growth, so that the subsequent compositions used in this experiment all used suggestin at concentrations below 80 μ M to prevent effects on normal cells.

2. Tumor cell inhibiting effect of combined medicine

Selecting a lung cancer cell line A549 according to tissue distribution characteristics of gefitinib and suogliflozin drug targets EGFR and SGLT 1/2; colorectal cancer cell lines LoVo, HT29, SW620, HCT 116; cervical cancer HeLa; ovarian cancer SKOV 3; gastric cancer NGC 27; bile duct cancer RBE; the experiment of the esophageal cancer KYSE30 and the like is verified. The method comprises the steps of digesting cells by trypsin when the cells grow to 80% density, carrying out passage and paving the cells in a 96-well plate, changing the culture medium containing the drug with corresponding concentration after 24 hours, and detecting the light absorption value under each concentration by using an MTT method after 48 hours.

The experiment is divided into:

control group: no drug is added, and only normal culture medium is used for culturing cells;

gefitinib test group: cells were treated with gefitinib alone in the medium, and 4 treatments were set at different concentrations, 5. mu.M, 10. mu.M, 20. mu.M, and 30. mu.M, respectively.

Gefitinib + suogliflozin combination test group: cells were treated with addition of sugelliflozin (20 μ M) and gefitinib at 4 different concentrations, 5 μ M, 10 μ M, 20 μ M, 30 μ M gefitinib.

After the culture, the cell growth inhibition rate was calculated by dividing the absorbance at each concentration by the absorbance of the control, and the results are shown in FIGS. 2-a to 2-e. In the figure, the concentration of gefitinib is used as a horizontal coordinate, and the cell growth inhibition rate is used as a vertical coordinate, so that the result shows that the inhibition effect of the gefitinib alone on tumor cells is limited, and the combination of the gefitinib and the gefitinib is beneficial to improving the inhibition effect on tumors.

3. Determination of IC50 value of combination drug

Taking the lung cancer cell line A549 as an example, the IC50 value of the gefitinib and suggestin combined drug is verified, and the experiment is divided into:

gefitinib test group (fig. 2-a-1): and only adding gefitinib into the culture medium to treat the cells, and detecting the cell survival rate after incubating for 1 h. 6 concentration gradients were set at 0. mu.M, 10. mu.M, 20. mu.M, 30. mu.M, 40. mu.M, 50. mu.M, respectively. The results showed that gefitinib had an IC50 value of 24.42 μ M for a549 cells.

Sugelliflozin test group (fig. 2-a-2): cells were treated with sugelliflozin only in the culture medium and the cell viability was measured after 1h incubation. 6 concentration gradients were set at 0. mu.M, 10. mu.M, 30. mu.M, 40. mu.M, 50. mu.M, 60. mu.M, respectively. The results showed that the IC50 value for sugelliflozin against a549 cells was 73.04 μ M.

Gefitinib + sugelliflozin combination test group 1 (fig. 2-a-3): cells were treated with sugelliflozin (10 μ M) and gefitinib added to the medium and assayed for cell viability after 1h of incubation. Gefitinib was set for 6 different concentration treatments, with gefitinib at 0 μ M, 10 μ M, 20 μ M, 30 μ M, 50 μ M, 60 μ M, respectively. The results showed an IC50 value of 17.03 μ M for a549 cells from this test group.

Gefitinib + sugelliflozin combination test group 2 (fig. 2-a-4): cells were treated with sugelliflozin (20 μ M) and gefitinib added to the medium and assayed for cell viability after 2h incubation. Gefitinib was set for 5 different concentration treatments, with gefitinib at 0 μ M, 10 μ M, 20 μ M, 30 μ M, 40 μ M, respectively. The results showed an IC50 value of 12.71 μ M for a549 cells from this test group.

Gefitinib + suogliflozin combination test group 3 (fig. 2-a-5): cells were treated with sugelliflozin (30 μ M) and gefitinib added to the medium and assayed for cell viability after 1h of incubation. Gefitinib was set for 6 different concentration treatments, with gefitinib at 0 μ M, 10 μ M, 20 μ M, 30 μ M, 40 μ M, 50 μ M, respectively. The results showed that the IC50 value for this test group for a549 cells was 9.318 μ M.

The result shows that with the use of the combination of the suogrel and the gefitinib, the inhibition rate of the gefitinib on the A549 cells is obviously enhanced, and the IC50 is reduced to be less than half of that of a single drug, so that the combined effect within the safe concentration range of the suogrel is better than the effect of each single drug. The results of the verification of other cell lines are shown in the attached drawings (2f-2j), and it is worth mentioning that the effect of the combination of sugelliflozin for enhancing the effect of targeting EGFR TKI is not limited to gefitinib alone, in FIG. 2k, FIG. 21, the invention further verifies afatinib and erlotinib which are two other EGFR inhibitors by taking A549 cells as an example, and the result shows that the addition of safe dose of sugelliflozin can effectively reduce the IC50 value of afatinib and erlotinib.

Example 2 combination of Soxhlet and Gefitinib to reverse Gefitinib resistance in tumor cells

1. And (4) screening gefitinib resistant cell strains.

After the gefitinib and sueglin combination in example 1 is obtained to significantly enhance the effectiveness of gefitinib, the present invention continues to explore whether the combination can reverse the gefitinib resistance of tumor cells. The A549 cells are cultured for a long time by using a culture medium containing gefitinib with gradually increased concentration, so that the cells can obtain drug resistance to the gefitinib, and the invention obtains an A549 gefitinib drug-resistant cell strain which can survive in 60uM gefitinib for a long time through 5 months of screening.

2. The combination of sugelliflozin and gefitinib reverses the resistance of tumor cells to gefitinib.

The gefitinib-resistant cell strain obtained by the invention can still be effectively killed by adding 30uM gefitinib and the sugelliflozin composition. It is shown that the combination of sugelliflozin and gefitinib reverses the resistance of tumor cells to gefitinib, and the results are shown in fig. 3.

Example 3 combination of Soxhlet with Apatinib

1. Tumor cell inhibiting effect of combined medicine

After the effectiveness of gefitinib in example 1 is obtained, the invention further verifies the other type of VEGFR-targeted TKI drug apatinib, and the liver cancer cell line HepG2 is preferentially selected according to the tissue distribution characteristics of the target points VEGFR and SGLT1/2 of the apatinib and the sugrezin drugs; colorectal cancer cell lines LoVo, HT29, SW620, SW 480; cervical cancer HeLa; ovarian cancer SKOV 3; gastric cancer NGC 27; bile duct cancer RBE; the experiment of the esophageal cancer KYSE30 and the like is verified. The method comprises the steps of growing cells to 80% density, digesting the cells with trypsin, carrying out passage and paving the cells in a 96-well plate, changing the cells into a culture medium containing apatinib, sueggliflozin and a combined drug of apatinib and sueggliflozin with corresponding concentrations after 24 hours, and detecting the absorbance value under each concentration by using an MTT method after 48 hours.

The experiment is divided into:

control group: no medicine is added, and only a normal culture medium is suitable for culturing cells;

apatinib test group: the cells were treated with apatinib alone in the medium, setting 4 different concentrations of treatment, 5 μ M, 10 μ M, 20 μ M, 30 μ M.

Apatinib + suggestin combination test group: cells were treated with addition of suggestin (20 μ M) and apatinib to the medium, setting 4 different concentrations of treatment, wherein apatinib was 5 μ M, 10 μ M, 20 μ M, 30 μ M, respectively.

The cell growth inhibition was calculated by dividing the absorbance at each concentration by the absorbance of the control, and the results are shown in FIGS. 4-a-1 to 4-a-5. The results of the figure, which uses the concentration of apatinib as the abscissa and the cell growth inhibition rate as the ordinate, show that the inhibition effect of apatinib on tumor cells is limited when the apatinib is used alone, and the combination of the two medicines is beneficial to improving the inhibition effect on tumors.

The invention preferentially selects the liver cancer cell line HepG2 for experimental verification. The method comprises the steps of growing cells to 80% density, digesting the cells with trypsin, carrying out passage and paving the cells in a 96-well plate, changing the cells into a culture medium containing apatinib, sueggliflozin and a combined drug of apatinib and sueggliflozin with corresponding concentrations after 24 hours, and detecting the absorbance value under each concentration by using an MTT method after 48 hours.

The experimental method is the same as before, and the incubation time is 1 h. The experiment shows that the blank control group, namely the HepG2 cells cultured normally, wherein the concentration of the sugelliflozin or the TKI medicament is 0, the survival rate of the cells of the blank control group is 100%, the concentration of the sugelliflozin adopted in other administration groups is 30 mu mol/L, the concentration of the TKI medicament is divided into the experiment groups shown in the table 2, and the results are shown in the accompanying drawings:

TABLE 2 administration group Experimental design

The results show that in each drug combination group, the drug combination group shows good inhibition effect on tumor cells, and the effect of the drug combination group is obviously superior to that of a control group which is singly administrated.

Example 5

Examples 1 to 4 are all thinIn order to further verify that the diabetes treatment drug suggestin and TKI inhibitor drugs discovered by the invention have effects in-vivo anti-tumor, the lung cancer A549 cell is selected and subjected to tumor-bearing treatment test by using Balbc nude mice produced by Witongli Hua. The cells are grown to the logarithmic phase, and A549 cells are collected and are resuspended to be 5 multiplied by 10 by serum-free DMEM medium⁷Each mouse was inoculated with 100. mu.l of 5X 10 cells per ml⁶Individual cells, tumor size was measured 19 days later and grouped by size, with the average size of tumors in each group being consistent. The administration is started after grouping, the administration dosage of the sugelliflozin is 200-400 mg according to the current sugelliflozin recommended daily administration dosage of diabetic patients, the administration dosage is selected by converting the dosage into the dosage of 22-44 mg per kg of body weight of mice, and finally, the administration of the sugelliflozin is carried out by selecting the dosage of 30 mg per kg in an oral administration mode. Gefitinib was administered at a dose of 100 mg per kg, determined according to previous studies to treat a549 transplantable tumors. The administration mode of the two medicines is consistent with the oral administration mode in the current clinic, and the administration is carried out by intragastric administration of mice. The dosing period was once every two days. Tumor size was measured every two days. After 40 days of administration, the test is ended and the tumor is dissected and weighed.

As shown in FIGS. 7-a-7-b-7-c, the single drugs of both sugliflozin and gefitinib can inhibit tumor growth (FIGS. 7-a-7-b-7-c), and the combination of sugliflozin and gefitinib has better tumor inhibition effect than the two drugs used alone. According to the evaluation of the effectiveness of the medicine, the requirement that the tumor growth inhibition rate is more than 60 percent and the p value is less than 0.05 is met. By calculating the tumor growth inhibition rate and the p value of each group, the single drug administration of the sugelliflozin and the gefitinib is judged to be ineffective finally, and the treatment effect of the sugelliflozin and gefitinib composite is effective.
