Abstract

Description

ALKYLCARBAMOYL NAPHTHALENYLOXY -OCTENOYLHYDROXYAMIDE DERIVATIVES HAVING
INHIBITORY ACTIVITY AGAINST HISTONE DEACETYLASE AND
PREPARATION THEREOF
FIELD OF THE INVENTION

The present invention relates to a novel alkylcarbamoyl naphthalenyloxyoctenoyl hydroxyamide derivative, a method for preparing same and an anticancer composition comprising same.

BACKGROUND OF THE INVENTION

Histones associate with DNAs in the nuclei of eukaryotic cells as basic proteins and are subject to reversible acetylation at the amino group of the lysine residue. The reversible acetylation is involved in the formation of chromatin of a higher order structure, the cell division cycle and ultimately the gene expression, and can be regulated by the dynamic balance established between the opposing activities of histone acetyl transferases (HATs) and histone deacetylases (HDACs): means enzymes neutralize or restore the positive charges of lysine residues (e.g., 4 lysine residues in H4) by acetylation/deacetylation to regulate the gene transcriptional level.
HDACs play an important role in cell cancerization or differentiation and their expression is enhanced under conditions such as hypoxia, lowered glucose, and cell cancerization, to inhibit the expression of cell proliferation inhibitors. That is, histone deacetylation by HDAC causes cell proliferation, while hyperacetylation of histone facilitates the inhibition of cell proliferation and cell differentiation. Therefore, when HDACs are inhibited, cell proliferation and angiogenesis can be controlled.
Abnormal histone deacetylation has been reported to cause acute promyelocytic leukemica (APL) (Lin R. J. et. al. Oncogene 20: 7204, 2001;
Zelent A. et. al. Oncogene 20: 7186, 2001). Specifically, abnormality in the regulation of HDAC activity leads to oncoprotein's transcriptional suppression and the formation of abnormal chromatin structures, which after causes normal cells to become cancer. Accordingly, HDAC has been one of the targets for the study of anticancer drugs as well as gene expression inhibitor and there have been attempts to develope HDAC inhibitors as anticancer drugs.
Recent anticancer drug studies through chromatin modeling have shown that HDAC inhibitors such as suberoylanilide hydroxamic acid (SAHA) or apicidin inhibit the proliferation of cancer cells and induce cell differentiation (Munster P. N. et al., Cancer research 61: 8492, 2001; Han J.
W. et. al. Cancer research 60: 6068, 2000).
Another HDAC inhibitor, n-butyrate was reported to be useful for the treatment of large intestine cancer. But it has to be used in such a high concentration in the order of milimolar (mM) that it disturbs the functions of other enzymes in cells, cytoskeleton, cell membrane, etc. Trichostatin A
(TSA) which enhances the differentiation and suppresses the proliferation of Friend murine erythroleukemia cells has been reported to inhibit HDAC
(Yoshida M. et al., Cancer research 47: 3688, 1987; Yoshida M. & Beppu T.
Exp Cell Res. 177: 122, 1988; Yoshida M. et al., J of Biol. Chem. 265: 17174, 1990).
Therefore, there has been a need for developing an improved HDAC
inhibitor. The present inventors have unexpectedly found that a novel alkylcarbamoyl naphthalenyloxyoctenoyl hydroxyamide derivative is an efficient inhibitor against cell proliferation which can be advantageously used for treating cancer.

SUMMARY OF THE INVENTION

It should be understood that Examples, while indicating preferred embodiments of the invention, are given by way of illustration only. From the above Examples, one skilled in the art can ascertain the essential characteristics of this invention, and without departing from the spirit and scope thereof, can make various changes and modifications of the invention to adapt it to various usage and conditions.

Test example 1 HDAC activity was analyzed using BIOMOL QuantizymeTM Assay system which comprised two steps of 1) enzyme reaction between HDAC and a substrate and 2) determination of the level of HDAC inhibitory activity. In step 1), 42 ,u,e of a buffer solution (25 mM Tris-HCl [pH 8.0], 137 mM
NaCl, 2.7 mM KCI, 1 mM MgCl2) and 50 of 250 M Fluor de LysTM
substrate were added to each well of a 96-well plate, to which 2.5 /a of a test compound (compounds of Example 1 to 49) was added. 0.5 0 of HeLa nuclear extract(10 M) (a source of HDAC enzymes) was then added thereto to a final concentration of 100 nM. The enzyme reaction was carried out for 1 hr. Subsequently, in step 2), 2 M tricostatin A was added to 50 ,ut of Flour de LysTM developer, followed by allowing the mixture to react at room temperature for 15 minutes. The light excited at 355 nm and emitted at 460 nm from the fluorophore was measured with a fluorometric plate reader. The intensity of the fluorescence increases as the enzyme activity is higher. The HDAC inhibitory activity of each of the test compounds was determined and compared with that of the control. And suberoylanilide hydroxamic acid (SAHA) (Biomol) was used at the same level with the test compounds as a comparative control.

The HDAC inhibitory concentrations (IC50) of the compounds according to the present invention are shown in Table 1.

Test Example 2 Inhibitory activities of the compounds synthesized in Examples against proliferation of cancer cells were examined by SRB (Sulforhodamine B) analysis using cervix adenocarcinoma Hela (Korean Cell Line Bank, KCLB 10002) and colon cancer cells HCT116 (Korean Cell Line Bank, KCLB 10247) as followed:
Cancer cells were inoculated into a 96-well microplate at a concentration of 1 x 103-3 x 103 cells/well and incubated under the condition of 37 C, 5% CO2 for 24 hrs. After the incubation was completed, 0.2, 1, 5, 25, or 100 pM of each of the compounds of Examples was added to the plate, and then the reactant was incubated again. After the substrate was stained, the anti-cancer activity was determined by comparing the amount of protein in the cells treated with compound of Examples with that of protein in non-treated cells.
Specificially, after the incubation was completed, the culture medium was removed from each well, and the cells were washed 3 times with PBS
(pH7.4). Then, a solution of 50% trichloroacetic acid (TCA) was added to each well in an amount of 50 ,ul/well at 4 C for 1 hr to fix them. Then, the microplate was washed 5 times with distilled water and dried at room temperature.
50 ,ut of a staining solution prepared by dissolving 0.4% SRB in 1%
acetic acid was added to the wells, and the microplate was kept at room temperature for 1 hr. The well plate was then washed 5 times with 1%
acetic acid to remove unbound SRB and dried at room temperature.
The stained cells were treated with 150 ,ut/well of 10 mM Tris-HCl solution (pH 10.5) to elute SRB from the cells, and the absorbance of each well at 520 nm was measured.
The ED50 value representing inhibition of the cancer cell growth by the extent of 50% was calculated from the measured absorbance, and the results are shown in Table 2.
When cancer cells were treated with a HDAC inhibitor, histone deacetylation would be inhibited, leading to an increase in the amount of acetyl-histone. In this test, the increased amount of acetyl-histone in the cancer cells was determined by using Western blotting, after the treatment with each of the compounds of Examples.
Hela cells were inoculated into a 6-well microplate at a concentration of 1.5 x 108 cells/well and incubated overnight under the condition of 371C, 5% CO2.
10 pM of each compound of Examples, and suberoylanilide hydroxamic acid (SAHA) as a control was added to the plate and the plate was incubated again for 24 hrs.
The cells were harvested in the presence of the test compound and were subjected to fractionation to separate the nuclei from the cells. The cells were allowed to swell in a hypotonic solution, lysed by several rounds of freezing-thawing cycles, and then centrifuged of 1,300 rpm for 5 min to collect the nuclei. The nuclei was lysed in a lysis buffer solution (20 mM
HEPES (pH 7.9), 25% glycerol, 420 mM KCI, 1.5 mM MgCl2, 0.2 mM
EDTA) to obtain a protein extract.
The resulting protein extract was subjected to SDS-PAGE to separate the proteins by the size and transferred onto the nitrocellulose membrane according to the conventional method.
The amount of acetylated histon H4 was measured using anti-acetyl histone H4 antibody (Upstate, USA) and evaluated the HDAC inhibitory activity of the inventive compounds by comparing the degree of increase of acetylated histone H4 relative to the control (SAHA).
The results are shown in Table 2.
