Embodiment 1
[0228] Example 1. Preparation of 3-[1-(2,4-dimethoxybenzyl)-2-oxo-2,5-dihydro-1H-pyrrol-3-yl]-N-hydroxyl propionamide ( 1e)
[0229]
[0230] Step 1. Preparation of Allyl-(2,4-Dimethoxybenzyl)amine (1b)
[0231] Under stirring, 0.32 ml of allyl bromide (3.66 mM) and 0.7 ml of diisopropylethylamine (3.99 mM) were added to 500 mg of 2,4-dimethoxybenzyl dissolved in dichloromethane In the reaction solution of amine (3.33 mM), the solution was left alone at room temperature. After neutralizing the reaction mixture with 10% NaOH solution, the mixture was extracted with chloroform, washed with saturated NaCl solution, washed with MgSO 4 Dry, filter, and concentrate in vacuo. The formed compound was purified by silica gel column chromatography using a solvent mixture of methanol and chloroform (1:9) as eluent to obtain 276 mg of allyl-(2,4-dimethoxybenzyl)amine (1b) ( Yield: 40%).
[0242] Example 2. Preparation of 3-(1-benzyl-2-oxo-2,5-dihydro-1H-pyrrol-3-yl)-N-hydroxyl-propionamide (2e)
[0243] 3-(1-Benzyl-2-oxo-2,5-dihydro-1H-pyrrol-3-yl)-N-hydroxy-propionamide (2e) was prepared analogously to that described in Example 1 above (See Table 1).
Embodiment 3
[0244] Example 3. Preparation of N-hydroxy-3-(2-oxo-1-phenethyl-2,5-dihydro-1H-pyrrol-3-yl)-propionamide (3e)
[0245] N-Hydroxy-3-(2-oxo-1-phenethyl-2,5-dihydro-1H-pyrrol-3-yl)-propionamide (3e ) (see Table 1).

The present invention provides a pharmaceutical composition for preventing and treating the cancer disease comprising lung cancer, bone cancer, pancreatic cancer, skin cancer, cancer of the head and neck, cutaneous or intraocular melanoma, uterine cancer, ovarian cancer, rectal cancer or cancer of the anal region, stomach cancer, colon cancer, breast cancer, gynecologic tumors, Hodgkin's disease, cancer of the esophagus, cancer of the small intestine, cancer of the endocrine system, sarcomas of soft tissues, cancer of the urethra, cancer of the penis, prostate cancer, chronic or acute leukemia, solid tumors of childhood, lymphocytic lymphonas, cancer of the bladder, cancer of the kidney or ureter, or neoplasms of the central nervous system, therefore, it can be used as the therapeutics for treating and preventing cancer diseases.
Description
technical field [0001] The present invention relates to novel uses of 2-oxo-heterocyclic compounds having anticancer activity and pharmaceutical compositions comprising said compounds. Background technique [0002] Cancer is characterized by the formation of groups of cells called tumors caused by abnormal, uncontrolled cell growth, infiltration into adjacent tissues, and extensive metastasis to other organs, a process called neoplasia. Worldwide, more than 20 million people suffer from cancer each year, of whom 6 million die from the disease each year. The origin of cancer is divided into internal factors such as genetic factors, immune factors, etc., and external factors such as various chemical substances, radiation, viruses, and the like. Cancer may result when the balance between oncogenes and tumor suppressor genes is disrupted by the above factors. [0003] Histone is a nuclear protein that binds to nuclear DNA. Histone acetylation occurs at the ε-amino group of the...
