Description

[0001] The present invention relates to a pharmaceutical composition for inhibiting fibrosarcoma metastasis, which contains ketotifen as an active ingredient.

The present invention relates to a pharmaceutical composition for inhibiting fibrous sarcoma cancer metastasis containing kettifen as an active ingredient.

Cancer cells mean that cancer cells move from one organ or native site to another organ or to other parts. It is known that cancer metastasis is mainly caused by malignant cancer cells. Most of the metastatic cancer cells come out of the primary cancer and penetrate into the lymphoid or vascular system, and then circulate through the tissue or blood vessels and then penetrate and grow in other tissues. Cancer is a typical feature of malignant tumors, and mortality from malignant cancer is known to account for 90% of all cancer deaths (Weigelt et al., 2005).

An important role involved in metastasis is angiogenesis, cell migration and epithelial-mesenchymal transition (EMT). To meet the metabolic needs that grow as cancer cells grow, they migrate from the epithelial state to the mesenchymal state for movement, which is called angiogenesis. Through this process, newly formed blood vessels are known to act as a pathway for cancer cells to leave the cancer tissue and enter the circulation system of the human body (intravasation). In addition, cancer cells that have secured mobility may indirectly enter the vascular circulation system using the lymphatic system.

Cancer cells must survive in the circulatory system until growth is arrested in new organs. At restrained, cancer cells are ejected from the circulatory system into surrounding tissues, and at new sites, the cells continue to grow and are known to form pre-angiogenic micrometastases. Thus, the growth of cancer cells is maintained by angiogenesis, resulting in the formation of an observable cancer. Therefore, in order for cancer cells to transfer, cancer cells must necessarily move.

The treatment of cancer is mainly surgical operation, chemotherapy, radiotherapy etc, but most of them have a significant effect. However, some surviving cancer cells migrate in the patient's body and are metastasized, so that the cancer is often recurred, so that the suffering of the patient is not reduced. Therefore, there is a need to develop a new therapeutic agent which can alleviate the suffering of cancer patients and alleviate the anxiety of cancer metastasis. Accordingly, anticancer agents have been studied focusing on the treatment of advanced cancer and the remarkable decrease in cancer recurrence rate.

In the case of drugs that inhibit cancer metastasis, it is important to identify appropriate markers for metastatic cancer. Studies on biomarkers have been actively conducted to date, There are still many difficulties in doing so. Particularly, there is a demand for the development of a useful anti-cancer agent that can suppress cancer metastasis after surgery.

On the other hand, Ketotifen (4- (methyl- 4-piperidylidene) -4Hbenzo [4,5] cyclohepta [1,2-b] thiophen-10 It has been commonly used as an antianaphylactic agent. Ketotifen has been used primarily as an oral preparation to prevent allergic diseases by directly inhibiting the release of allergen-inducing mediators from mast cells. Ketotifen is also formulated into syrups or capsules and is used to treat asthma, allergic bronchitis, allergic conjunctivitis, allergic dermatitis, atopic dermatitis and the like, and is also used as an eye drop for ophthalmic diseases and as a topical application for external application .

As described above, various pharmacological effects of ketotifen are known, but the effect of ketotifen on the inhibition of metastasis of fibre sarcoma has not been reported, and there have been no studies on this.

The fibrosarcoma cancer cell line HT-1080 cells were cultured in RPMI 1640 (Weljin) medium containing 10% fetal bovine serum (FBS) and L-glutamine. 1% antibiotic (penicillin-G 100 units / ml / streptomycin 100 ug / ml) was added to the medium. Cell cultures were performed in an incubator (Forma 3111, formma Scientific.Lnc. USA) containing carbon dioxide at a temperature of 37 ° C and a concentration of 5%.

1-2. Measurement of cell migration inhibitory activity of ketotifen

The cell migration inhibitory activity of HT-1080 cells prepared in Example 1-1 was measured.

Specifically, for the migration experiment, a multi-well chamber of Neuro Probe coated with 10 μg / ml of fibronectin as a chemoattractant was used (Park et al., 2011) . Ketotifene of the present invention was dissolved in DMSO and pretreated for each concentration beforehand. HT-1080 cells were suspended in DMEM medium at a density of 1.1 × 10 ⁷ cells / ml, and 25 μl of them were taken in an upper chamber of a multichamber. Thereafter, an 8 μm polyhydrocarbon filter was placed in the middle well, DMEM medium containing 3% serum was placed in the lower well, and then cultured at 37 ° C. for 4 hours. After completion of the incubation, the non-migrating cells on the upper surface of the filter were wiped off thoroughly, and the cells migrating on the lower surface were stained using a Diff-quick dye. Five randomly selected cells were selected from the stained cells, and each cell in the selected region was identified by a microscope with a magnification of 400X and counted. The results are shown in Fig.

As shown in FIG. 1, the kettotin of the present invention significantly inhibited the migration of HT-1080 cells, a fibrosarcoma cancer cell line, at a concentration of 25 μM.

Therefore, it was confirmed that the ketotifen of the present invention significantly inhibited the migration of HT-1080 cells, which is a cell sarcoma cancer cell line, to thereby exert an excellent effect of inhibiting metastasis of fibrosarcoma cancer.

Example 2. Measurement of inhibitory activity of ketotifene against HT-1080 cells

Matrigel (TM) invasion assay was performed on the HT-1080 cells prepared in Example 1-1 to confirm the effect of ketotifen on the infiltration of HT-1080 cells, a fibrosarcoma cancer cell line. The inside of the transwell insert was coated with 500 μg / ml of Matrigel to induce invasion. Twenty nM of TPA (12-O-tetradecanoylphorbol-13 acetate) inducing invasion and various concentrations of ketotifen were treated with the HT-1080 cell line and cultured for 1 hour. 1 x 10 ⁴ cells per well were placed in a container, cultured in an incubator for 24 hours, and the number of cells moved downward was counted under a 200-fold microscope. The results are shown in Fig.

As shown in Fig. 2, it was confirmed that ketotifene inhibits the infiltration of HT-1080 cells in a concentration-dependent manner.

Example 3. Measurement of effect of ketotifen on the expression of cell migration-related proteins

Western blotting was performed to determine the effect of HT-1080 on cell migration-related proteins in ketotifen treatment. TPA, and ketotifene, respectively, on the expression of cdc42 and Rho, the cell migration-related proteins of HT-1080, and the results are shown in Fig.

As shown in FIG. 3, the expression of cdc42 and Rho was increased by TPA treatment, but the expression of these proteins was decreased when keto-typhine was treated.

Example 4. Measurement of the effect of kettifen on the expression and activity of cell infiltrating MMP-9 (Matrix metallopeptidase 9)

MMP-9 (Matrix metallopeptidase 9) is a gene involved in invasion and metastasis of cancer, and the effect of ketotifen on the expression and activity of MMP-9 was measured.

The HT-1080 cell line was treated with TPA and ketotifene, respectively, and the proteins extracted from the cells were electrophoresed to confirm the MMP-9 band. The results are shown in FIG.

As shown in FIG. 4A, an increase in MMP-9 was observed upon TPA treatment, and it was confirmed that treatment with ketotifen inhibited the expression of MMP-9 in a concentration-dependent manner.

Also, as shown in FIG. 4B, it was confirmed that MMP-9 increased in secretion by TPA was reduced by treatment with ketotifen. This indicates that ketotifene inhibits the activity of MMP-9 through inhibition of MMP-9 expression and has an activity of inhibiting invasion and metastasis of cancer cells.
