Problems solved by technology

However, the use of conventional drugs for treatment can not achieve satisfactory results, and has various side effects, which limits the use of conventional drugs
[0011] For example, anti-inflammatory drugs such as aspirin or butazolin have been used to relieve the syndromes of OA and PA, however, it is difficult to keep these drugs administered because of their side effects, such as severe gastric Stimulation leading to gastritis, gastric ulcer, etc.

Embodiment 1

[0224] Example 1. Preparation of 3-[1-(2,4-dimethoxybenzyl)-2-oxo-2,5-dihydro-1H-pyrrol-3-yl]-N-hydroxyl propionamide ( 1e)

[0225]

[0226] Step 1. Preparation of Allyl-(2,4-Dimethoxybenzyl)amine (1b)

[0227] 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 the reaction mixture was neutralized 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%).

Embodiment 2

[0238] Example 2. Preparation of 3-(1-benzyl-2-oxo-2,5-dihydro-1H-pyrrol-3-yl)-N-hydroxyl-propionamide (2e)

[0239] 3-(1-Benzyl-2-oxo-2,5-dihydro-1H-pyrrol-3-yl)-N-hydroxy-propionamide (2e) was prepared in a similar manner to that described in Example 1 above 1 (see Table 1).

Embodiment 3

[0240] Example 3. Preparation of N-hydroxy-3-(2-oxo-1-phenethyl-2,5-dihydro-1H-pyrrol-3-yl)-propionamide (3e)

[0241] N-Hydroxy-3-(2-oxo-1-phenethyl-2,5-dihydro-1H-pyrrol-3-yl)-propionamide (3e) was prepared in a similar manner to that described in the above examples 1 (see Table 1).

Abstract

The present invention relates to novel 2-oxo-cyclic compounds, processes for their preparation and pharmaceutical compositions containing said compounds. The present invention provides a pharmaceutical composition for the prevention and treatment of inflammatory diseases, including pain or inflammation caused by rheumatic diseases, for example, rheumatoid arthritis, juvenile spondyloarthropathy, gout, osteoarthritis, systemic Lupus erythematosus and juvenile arthritis and inflammatory syndromes, eg due to myositis, gingivitis, synovitis, ankylosing spondylitis, burstitis, burns and scars, inflammatory Crohn's disease, type I diabetes. Thus, it can be used as a therapeutic method in the treatment and prevention of inflammatory diseases.

Description

technical field [0001] The present invention relates to novel 2-oxo-heterocyclic compounds which are effective anti-inflammatory agents and pharmaceutical compositions comprising said compounds. Background technique [0002] Inflammation due to mechanical scars or various bacterial infections etc. is a normal reaction of the human body related to edema, pain etc. Usually, arthritic syndrome occurs only temporarily, but, when severe, it can cause long-term and eventual deformity. Joint disease can be divided into several groups of diseases, such as rheumatoid arthritis (RA), rheumatic inflammation associated with the disease, etc. Of these, specifically, arthritis is the most frequent and is a chronic disease characterized by inflammatory changes in the synovial lining of the joint capsule, which may progress to affect all joints of the body, at worst will cause disability. Progressive joint diseases such as rheumatoid arthritis cause joint disorders such as joint deformit...
