摘要:
The present invention relates to a novel anticancer composition, and more specifically relates to a maleic acid derivative compound of Chemical Formula 1, to a production method for the compound, and to a pharmaceutical composition comprising the compound. The maleic acid derivative of the present invention suppresses the expression of AIMP2-DX2 and hence selectively suppresses the growth of cancer cell lines without acting on normal cells, and thus pharmaceutical compositions containing the maleic acid derivative of the present invention and pharmaceutically acceptable salts thereof as active ingredients can be used to prevent and treat cancer.

The present invention relates to a method for screening an anticancer agent which inhibits the binding of AIMP2-DX2 and HSP70. More particularly, the present invention relates to a method for screening an anticancer agent and an anticancer composition comprising an anticancer agent screened by the method as an active ingredient, the method comprising: a step of contacting AIMP2-DX2 or a fragment thereof with HSP70 of a fragment thereof in the presence or absence of a test substance; a step of measuring the binding of AIMP2-DX2 and HSP70; a step of determining a change in the level of binding of AIMP2-DX2 and HSP70 by the test substance; a step of screening a test substance which reduces the level of binding of AIMP2-DX2 and HSP70; and a step of identifying an anticancer activity of the screened test substance in cells or animals. The present invention can be effectively used to develop an anticancer agent with a completely new mechanism of action on the basis of the discovery that HSP70 is a regulator that directly binds to and stabilizes AIMP2-DX3, which is important for cancer development and progression. In addition, the pharmaceutical composition for preventing or treating cancer comprising, as an active ingredient, an anticancer agent screened according to the method of the present invention inhibits the expression of HSP70 or inhibits the binding of HSP70 and AIMP2-DX2, thereby lowering the level of AIMP2-DX2 protein, and can effectively prevent the progression of cancer. As such, the pharmaceutical composition can be useful for developing a cancer treating agent.

The present invention relates to a novel anticancer composition, and more specifically, to: an anticancer pharmaceutical composition comprising a compound represented by chemical formula 1 or a pharmaceutically acceptable salt thereof; a method for preventing or treating cancer, comprising a step of administering an effective amount of a compound represented by chemical formula 1 or a pharmaceutically acceptable salt thereof to an individual in need thereof; and a use of a compound represented by chemical formula 1 or a pharmaceutically acceptable salt thereof for preparing an agent for preventing or treating cancer. The compound of the present invention inhibits, dependent on the concentration, the protein level of AIMP2-DX2, which is overexpressed in lung cancer cells, and inhibits, dependent on the concentration, the survival of cancer cells without acting on normal cells, and thus a pharmaceutical composition comprising the compound of the present invention or a pharmaceutically acceptable salt thereof can be used for preventing and treating cancer.
摘要:
The present invention pertains to a novel compound having anticancer activity, and a method for producing same, and more specifically, to a novel compound that exhibits excellent anticancer activity by inhibiting the expression of AIMP2-DX2, and a method for producing same. The compound represented by chemical formula 1 according to the present invention is highly effective in inhibiting the expression of AIMP2-DX2, and thus can be very advantageously used for the development of agents for treating various diseases, in particular cancer, caused by AIMP2-DX2.
摘要:
The present invention relates to a method for scanning a cancer metastasis inhibitor by analyzing the activity of lysyl-tRNA synthetase (KRS) in a cancer cell line cultured in a three-dimensional collagen gel environment, and to a method for monitoring the dissemination of cancer cells from aggregated cancer cells, and the epithelial-mesenchymal transition, migration, invasion, and metastasis of cancer cells. Specifically, it was verified that, in the case where a cell line or a spheroidically aggregated cell line, in which KRS has been regulated to be expressed or unexpressed, was constructed by using various colorectal cancer cells including HCT116 cell line and then cultured in a two-dimensional environment, the incomplete epithelial-to-mesenchymal transition phenotype (incomplete ECM phenotype) was induced in the cell line inhibiting KRS expression, and the inhibition of KRS expression inhibited cell-extracellular matrix (ECM) adhesion and cell-ECM signaling activity. In addition, it was verified that, in the case where the constructed spheroid cell line was cultured in an aqueous environment or a three-dimensional collage gel culture environment, the inhibition of KRS expression induced cells into mesenchymal cells but failed to reach the disintegration of cell-cell adhesion; inhibited the cell-ECM adhesion and the related signaling activity, causing the inhibition of the dissemination of cells from spheroid cells cultured in a three-dimensional collagen gel culture environment; and failed to induce the dissemination of cells through TGFβ1 present in the cellular microenvironment. Thus, the present invention can be used as a method for screening a cancer metastasis inhibitor and a method for monitoring the migration, invasion and metastasis of cancer cells, and will be useful as one of the screening methods capable of creating low-cost, high-efficient added value at the time of pre-clinical tests required for drug development.
摘要:
The present invention relates to the use of a novel aminopyridine derivative to prevent or treat cancer, and more particularly to a carcinostatic composition including a compound of Formula 1 or a derivative thereof as an active principle. The compound of the present invention degrades the activation of AIMP2-D7C2 targeted by a novel anticancer drug so as to effectively in-duce destruction of cancer cells, thus effecting prevention and treatment of cancer. Therefore the compound of the present invention can be used to prevent and treat cancer.
