Description

[0001] The present invention relates to a composition for preventing or treating cancer comprising a phenyloxazole-based derivative,

The present invention relates to a pharmaceutical composition for preventing or treating cancer comprising a phenyloxazole-based derivative, a composition for enhancing an anti-cancer effect, or a health functional food for cancer prevention or improvement.

Receptor tyrosine kinases (RTKs) are transmembrane proteins that penetrate cell membranes and are one of the most important receptor groups responsible for cell signaling systems that regulate cell proliferation, cell migration, cell cycle and cell differentiation Human RTKs are classified into about 20. Platelet Derived Growth Factor Receptor (PDGFR) can be activated by ligand platelet-derived growth factor (PDGF), mitogen-activated protein kinases (MAPK), phosphatidyl Inositol 3-kinase (PI3K) and STAT3 (signal transducer and activator of transcription 3) can activate the downstream signaling pathway. Activation of PDGFR, including mutations, is observed in GISTs, Glioblastoma multiforme, and chronic myeloid leukemia. An internal tandem duplication (IDT) mutation in the juxtamembrane domain of FLT3 (FMS-like tyrosine kinase 3) gene in approximately 30% of patients with acute myeloid leukemia (AML) About 3% of patients with acute lymphoblastic leukemia (ALL) have mutations, and patients with these mutations are known to have poor prognosis. Thus, FLT3 inhibition may be helpful in the treatment of acute myelogenous leukemia and acute lymphoblastic leukemia. c-Kit can be activated by ligand stem cell factor (SCF), and point mutants such as D816V or V560G are constantly activated without ligand to resist cell proliferation, cell survival and apoptosis Lt; / RTI > In particular, c-Kit activates mastocytosis and induces mastocytosis to increase expression in various organs (skin, liver, gastrointestinal tract, genitalia, etc.) gastrointestinal stromal tumor (GIST), small cell lung cancer, testicular cancer, and polymorphic glioblastoma. Patients with about 70-80% GISTs have a gain-of-function mutation in c-Kit. In addition, we have reported the possibility of rapid growth and metastasis of non-small cell lung cancer due to the activation of c-Kit of non-small cell lung cancer by increasing SCF by nicotine.

Cyclin-depenedent kinase (CDK) is a serine / threonine protein kinase that is crucial to the cell cycle. These complexes consist of two catalytic small molecules, cyclin-dependent kinase (CDK) and regulatory small molecule, cyclin. Each CDK is complexed with a specific cyclin to activate it. The progression of each cell cycle can be controlled by specific CDK / cyclin complexes. CDK1 / cyclin B1, CDK2 / cycle E, and CDK2 / cyclin A are important factors in cell cycle progression.

A number of RTK inhibitors have been tried in clinical trials and have shown initial clinical response, but they are transient and have a problem that resistance may develop rapidly. The RTK inhibitor may cause a D816V mutation in the KIT, a D842V mutation in the PDGFR, and a D835V mutation in the FLT3, interfering with the binding of the RTK inhibitor to the target by various mutations.

Therefore, RTK activation and rapid cell cycle progression are involved in the regulation of abnormal cells in various cancer species. Therefore, the development of inhibitors targeting RTK activity and CDK1 / cyclin B and CDK2 / cyclin A and CDK5 / p35 complex kinase activity Is required.

A 0.5 mg / mL MTT solution was then added to each well and further incubated at 37 [deg.] C for 3 hours. After incubation, the supernatant was removed and the formazan crystals formed were dissolved in DMSO and measured at 590 nm using a spectrophotometer. Controls were treated with DMSO and the results are shown in Table 6 as relative growth rates relative to 100% survival.

3. Lactate dehydrogenase (Lactate Dehydrogenase , LDH ) analysis

In normal cells, the LDH enzyme does not pass through the cell membrane but is released by cell membrane destruction during cell death. Therefore, LDH enzyme can be measured in cell culture to measure apoptosis. First, 10 μM of the derivative 1 was treated for 1, 3, 8, 24, or 48 hours with human lung cancer cell line H1299, and then the cell supernatant was collected and dispensed into a 96-well plate. This was analyzed by spectrophotometric analysis at 450 nm using an LDH assay kit (LDH assay kit, Dojindo, Japan).

As a result, as shown in Fig. 3, LDH enzyme was increased 1.6 times as compared with the control group after 48 hours of treatment with the derivative 1. Thus, it has been confirmed that the derivative 1 [5- (4-bromophenyl) -N- (naphthalen-1-yl) oxazol-2-amine] has apoptotic effect on human lung cancer cells.

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

H1299 lung cancer cells cultured in the same manner as in Example 3 were treated with 5 μM of derivative 1 and 1 μM of known anticancer agent 5-FU (10 μM) for 48 hours, and cell viability was analyzed by MTT assay.

As a result, as shown in Fig. 4, when the 5-FU and the derivative 1 were co-administered, the cell proliferation inhibitory effect was increased by 60% or more as compared with the case of 5-FU alone. Accordingly, it has been found that the derivative 1 [5- (4-bromophenyl) -N- (naphthalen-1-yl) oxazol-2-amine] as the phenyloxazole derivative according to the present invention can increase the effect It was confirmed that it could be used as an anticancer adjuvant.

< Example  5> Confirmation of anticancer effect by combination treatment with irradiation

H1299 lung cancer cells cultured in the same manner as in Example 3 were dispensed into 6 cm cell culture plates, and the derivative 1 synthesized in Example 1 was treated with 3 or more times of 1 or 5 μM concentration. Then, gamma radiation was irradiated at 2, 4, 6 or 8 Gy and cultured at 5% CO 2 and 37 ° C for 7 days. The cultured cells were recovered, 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. 5A.

As a result, it was confirmed that the surviving fraction was remarkably decreased when 5 μM concentration of the derivative 1 according to the present invention was treated with irradiation.

In addition, cleavage of caspase-3 (caspase-3) involved in apoptosis and PARP (poly-ADP ribose polymerase) involved in DNA repair was confirmed by Western blotting in the same manner as in 1. of Example 3 above. At this time, proteins and cleaved PARP proteins were detected with caspase-3 antibody (Cell signaling technology, Inc. USA) and PARP-1 antibody (PARP-1, Cell signaling technology, Inc. USA).

As a result, it was confirmed that the expression of PARP and truncated caspase-3 protein cleaved when the derivative 1 according to the present invention at a concentration of 5 μM and 1 Gy of radiation were treated together as shown in FIG. 5B.
