Description

Novel imidazolyl pyrimidine derivatives, preparation method thereof and pharmaceutical composition for the prevention or treatment of cancer containing the same as an active ingredient

The present invention relates to a novel imidazolyl pyrimidine derivative, a preparation method thereof and a pharmaceutical composition for preventing or treating cancer containing the same as an active ingredient.

Human hepatocellular carcinoma (HCC) is a disease caused by long term liver inflammation.

Although surgical and percutaneous radiofrequency ablation improves patient survival, new methods for obtaining effective treatment for advanced human hepatocellular carcinoma (HCC) are needed. Treatment alternatives are needed. Thus, the induction of apoptosis by chemotherapy and low molecular weight transport is an emerging alternative.

Transforming growth factor beta-1 (TGF-β1) strongly inhibits human hepatocellular carcinoma (HCC) cell growth. In particular, it promotes cell growth in non-epithelial cells, such as fibroblasts and stellate cells, while in rodents and by cell death or cell cycle arrest. It inhibits cell growth in both human hepatocellular carcinoma (HCC) cells.

Induction of apoptosis by TGF-β1 in human hepatocellular carcinoma (HCC) cells is mediated by dephosphorylation of cdc2 Tyr15 (active form of cdc2), ie, reduction in cdc2 phosphorylation. The cdc2 activity is induced by Wee1 kinase downregulation, and cdc2 activity by decreasing Tyr15 phosphorylation is very important for TGF-β1-induced apoptosis in human hepatocellular carcinoma (HCC) cells. A decrease in Wee1 kinase expression is observed after TGF-β1 treatment, and cdc2 phosphorylation is regulated by Wee1 kinase. From this, it can be said that TGF-β1-mediated apoptosis is induced in the Wee1 / cdc2 axis.

In surgically excised samples, Wee1 kinase is overexpressed in human hepatocellular carcinoma (HCC), but kinase expression is not observed in non-cancerous tissues including cirrhotic tissue. Overexpression of Wee1 kinase has been reported in other tumor types, including brain tumors and leukemia (Non-Patent Document 1, Harris PS et al., (2014) Integrated genomic analysis identifies the mitotic checkpoint kinase WEE1 as a novel therapeutic target in medulloblastoma Mol Cancer 13: 72). In brain tumors, Wee1 kinase expression is upregulated only in tumor cells, and elevated kinases play an important role in cancer cell survival.

Wee1 kinase is a negative regulator of cdc2. Since TGF-β1 is a multifunctional cytokine, it is not a practical therapeutic alternative. Wee1 kinase negatively regulates the G2 / M phase by inhibiting the early stages of mitosis before DNA damage is repaired, thereby preventing premature mitotic entry and subsequent cell death. It is considered. Certain inhibitors or siRNAs may be used to inhibit Wee1 kinase to induce apoptosis in human hepatocellular carcinoma (HCC) cells. Thus, Wee1 kinase inhibitors may be new therapeutic strategies and alternatives emerging in Wee1 kinase-overexpressing carcinomas such as human hepatocellular carcinoma (HCC), and these types of inhibitors may present a realistic therapeutic alternative to advanced solid cancers. Can be.

Experimental Example 1 Evaluation of Wee1 Kinase Inhibitory Activity

In order to evaluate the inhibitory activity of Wee1 kinase of the compound represented by Formula 1 according to the present invention, the following experiment was performed.

Recombinant Wee1 kinase (Invitrogen, Carlsbad, CA), 3.4umol / l poly G: T (4: 1) (Signal Chem, Richmond, BC, Canada), 20 μmol / L ATP (Invitrogen, Carlsbad, CA) in 384-well plates ) Was added to the kinase reaction buffer (40 mmol / L TrisHCl, 10 mmol / L MgCl 2 and 0.1 μg / μL bovine serum albumin (BSA)) and mixed. Examples 1-21 compounds according to the present invention were added at concentrations of 1 μM or less, more than 1 μM to 10 μM or less, more than 10 μM to 100 μM and more than 100 μM, and then reacted in a 30 ° C. incubator for 1 hour. After the reaction was completed, the same amount of Kinase-Glo (Promega, Madison, WI) solution was added for 1 hour and the detection solution was added for 10 minutes at room temperature. The IC ₅₀ value of the kinase was calculated by measuring the amount of luciferase using a microplate enzyme-linked immunosorbent assay reader (Bio-Tek). The results are shown in Table 2 below.

From the structural differences of the above compounds, Wee1 kinase inhibitory activity is remarkably changed. That is, in the case of having the iodo (I) substituent at the pyrimidine 5 position as in the compound of Example 1 of the present invention, it has a Wee1 kinase inhibitory activity of up to about 20 times that of the above-described Example 15-20 compound.

Also, when the Example 7 compound is compared with the Example 21 compound, the Example 7 compound according to the present invention has an iodo (I) substituent at the pyrimidine 5 position, which is about 4 times higher than that of the Example 21 compound. It can be confirmed that it has Wee1 kinase inhibitory activity.

Accordingly, the imidazolyl pyrimidine derivatives, optical isomers thereof or pharmaceutically acceptable salts thereof according to the present invention exhibit excellent inhibitory activity of Wee1 kinase and therefore are used for the prevention or treatment of diseases related to Wee1 kinase, for example, liver cancer. It can be usefully used as a pharmaceutical composition.
