Description

TECHNICAL FIELD The present invention relates to a composition for preventing or treating cancer comprising a pyridine-based derivative,

The present invention relates to a pharmaceutical composition for preventing or treating cancer comprising a pyridine derivative as an active ingredient, a composition for promoting radiation therapy effect, or a health functional food for cancer prevention or improvement.

With the development of modern medicine, many diseases are being treated and prevented, but cancer is still one of the most difficult diseases to treat. Cancer is currently the number one cause of death, and it is increasing continuously.

Chemotherapy, surgery, and radiation therapy have been used to treat cancer. Of these, chemotherapy is the most commonly used method for treating cancer as an anticancer drug. Today, about 60 kinds of anticancer drugs are used in clinical practice. As knowledge of cancer development and characteristics of cancer cells is well known, new anticancer drugs are being developed. However, most of the anticancer drugs currently used in clinical practice are accompanied by side effects such as nausea, vomiting, ulcers of the mouth and small intestine, diarrhea, hair loss, and bone marrow suppression in which the production of effective components of blood is decreased. For example, mitomycin-C is known to cause renal insufficiency, and adriamycin has a side effect such as bone marrow suppression. In particular, cisplatin, which is the most useful anticancer drug developed so far, is widely used for the treatment of testicular cancer, ovarian cancer, lung cancer, head and neck cancer, bladder cancer, stomach cancer and cervical cancer, but hematopoietic toxicity such as anemia, vomiting, Such as kidney toxicity such as digestive tract toxicity, kidney tubular damage, hearing loss, internal electrolyte abnormality, shock, peripheral neuropathy and the like.

Therefore, there is a desperate need to develop a new anticancer drug having excellent safety.

In addition, since the number of cancer patients receiving radiation therapy is increasing every year, the importance of radiation therapy for cancer treatment is also increasing.

However, it has been pointed out that the acquisition of radiation resistance of cancer cells and the damage of normal tissues during high-dose radiation therapy have been pointed out as a problem of reducing the efficiency of radiation therapy. Therefore, studies on radiation therapy sensitizers to improve the efficiency of radiation therapy have been made.

The radiation therapy sensitizers reported so far are mainly anticancer agents such as Taxol and cisplatin which can be used as radiation therapy sensitizers in solid tumors such as breast cancer, uterine cancer, lung cancer, stomach cancer and colon cancer have.

In addition, tirapazamine is a radiotherapeutic effect enhancer that is not used as an anticancer agent but only for radiation therapy. However, it is effective only for hypoxic tumor cells. Because of the pressure inside the tumor due to hypoxic conditions, It is known that the effect is insignificant in clinical radiotherapy.

These radiation therapy sensitizers have a problem that their use is limited since they have high side effects. Although there is a difference in sensitivity in the radiation therapy for cancer cells, if the above sensitivity can be improved, it is preferable to irradiate the patient with a smaller amount of radiation to obtain the same therapeutic effect.

Therefore, it is necessary to develop an anticancer agent which can increase the sensitivity of cancer cells to radiation.

< Example  1 > Catechin  Confirmation of expression inhibition

It was confirmed that the β-catenin expression was inhibited by the pyridine derivative according to the present invention. For this, pyridine-based derivatives of the formula (2) or (3) were treated with 10 μM each of the DLD-1 colorectal cancer cells cultured as described in 2 of the Reference Example 1, and then cultured for 48 hours under the conditions of 5% CO 2 and 37 ° C. Then, a TCF-top flash reporter plasmid kit (TOPFlash, Millipore, Merck, USA) was introduced and measured using a luciferase activity assay kit (Promega, USA).

As a result, as shown in FIG. 1, it was confirmed that the activity against the Wnt3A-induced top flash reporter was suppressed by the pyridine-based derivative of the above formula (2) or (3).

< Example  2> On cell apoptosis  Cell death by

The DLD-1 human colon cancer cell line and the APC normal cell line RKO colorectal cancer cell line in which APC, which is a cancer suppressor gene cultured as in Reference Example 1, 2, were mutagenized were treated with the pyridine derivative of Formula 2 or Formula 3 Cell apoptosis induced by apoptotic cell death was induced.

For this, the cells were treated with 10 μM each of the pyridine derivatives of Chemical Formula (2) or Chemical Formula (3), and then cultured for 48 hours at 5% CO 2 and 37 ° C. Cells were recovered and double stained with propidium iodide (PI) and Annexin V (BD bioscience, USA), and subjected to FACS (Fluorescence activated cell sorter) (AnnexinV + / PI - ).

As a result, as shown in FIG. 2, when the pyridine-based derivatives of Chemical Formula 2 or 3 were treated, it was confirmed that apoptosis was increased about 2.2-fold and 1.2-fold only in DLD-1 colon cancer cells, respectively.

< Example  3> Tan kira ( TNKS ) Enzyme activity Inhibition  Measure

(Tankyrase 1 colorimetric activity assay kit, Cat # 4500-192-K, Trevigen, RnD systems, USA) in which the pyridine-based derivatives of Formula 2 or 3 can inhibit TNKS enzyme activity ) According to the manufacturer's instructions.

4,3-d] pyrimidin-4-one [2- (4-trifluoromethyl-phenyl) -3,5,7,8-tetradihydrothiopyrano [ - (trifluoromethyl-phenyl) -3,5,7,8-tetradihydro-thiopyrano [4,3-d] pyrimidin-4-one, XAV939] was used.

In addition, the PARP-1 colorimetric assay kit (Cat # 4677-096-K, Trevigen, RnD) was used to determine whether the pyridine-based derivatives of Formula 2 or Formula 3 inhibited PARP (poly-ADP ribose polymerase) systmes) according to the manufacturer 's instructions.

At this time, 1 μM of Olaparib was used as a positive control, and the results of TNKS or PARP inhibition are shown in Table 1 below.

TNKS -One Inhibition (Compared to 0% in the control group) PARP Inhibition density( μM ) 10 20 20 Pyridine derivative 1

65.9 ± 3.2 77.4 ± 2.5 0 ± 0.1
Pyridine derivative 2
(Formula 3)
38.6 ± 2.4 52.2 + 1.7 0.6 ± 0.3

At this time, XAV939 inhibited the activity of TNKS-1 enzyme by about 76% at 100 nM treatment and inhibited PARP enzyme activity by 88% at 1 μM treatment of Olaflavin.

As shown in Table 1, the pyridine derivatives of the formula (2) or (3) according to the present invention inhibited the activity of TNKS-1 enzyme, respectively, but did not inhibit PARP. Therefore, it was determined that the activity of the pyridine derivative of the formula (2) or (3) was specific to the TNKS enzyme.

< Example  4> Confirmation of anticancer effect by combination treatment with irradiation

DLD-1 colorectal cancer cells or RKO colorectal cancer cells in which the APC gene mutated as described in Reference Example 1 2 were mutated were placed in a 6 cm cell culture plate and the pyridine derivative of Formula 2 or 3 was dissolved in a concentration of 10 μM Respectively. Then, 3 Gy of gamma radiation was irradiated and cultured at 5% CO 2 and 37 ° C for 7 days. The cultured cells were harvested, stained with a 1% methylene blue mixed solution in 100% methanol, and the viable cells in which the colonies were formed were counted. The results are shown in FIG.

As a result, it was confirmed that the surviving fraction was remarkably decreased when the pyridine-based derivative of the formula (2) or the formula (3) was treated with irradiation.

Therefore, it was confirmed through FIG. 3 that the pyridine-based derivatives of Formula 2 or Formula 3 can be used as a radiotherapy adjuvant which can enhance the radiation-treating effect.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various modifications and changes may be made without departing from the scope of the appended claims.
