Definitions
- the present invention relates to an agent for treating or preventing an inflammatory bowel disease, comprising a particular amino acid(s).
- the present invention also relates to an agent for inhibiting TNF production, comprising a particular amino acid(s).
- An inflammatory bowel disease is a generic term for enteropathy with inflammation, and mainly includes ulcerative colitis and Crohn's disease.
- the ulcerative colitis is a diffuse non-specific inflammatory disease where large bowel mucosa or submucosa is affected and erosion or ulcer is often formed.
- Clinical symptoms are mucous and bloody stools, abdominal pain, blood stools, watery stools, fever, lack of appetite, malevolence, emesis and the like.
- agents for treating the ulcerative colitis salazosulfapyridine, adrenal cortex steroids, immunosuppressants, 5-aminosalicylic acid (5-ASA) and the like are used, but it can not be said that these agents are enough to treat the ulcerative colitis.
- Crohn's disease is an idiopathic chronic enteritis of unknown cause, and exhibits non-specific inflammatory symptoms in intestines from a small intestine to a large intestine. Its lesions are composed of granulomatous lesions with fibrosis and ulcer, and it is likely that the lesions appear in all gastrointestinal area from an oral cavity to an anus.
- the clinical symptoms of Crohn's disease include abdominal pain, general malaise, diarrhea, melena, occult blood positive, fever, weight loss, anemia, ileus symptom, abdominal tumor, malevolence, emesis and peritonitis symptom.
- Crohn's disease simultaneously causes various gastrointestinal and parenteral symptoms, e.g., intestinal stenosis, intestinal perforation, abdominal abscess and heavy hemorrhage which are serious conditions, in addition to nutritional disorder, and often requires procedures such as intestinal surgery.
- a high calorie infusion or an enteral nutrition is performed for the purpose of improving the nutritional condition.
- a risk of bacterial translocation is increased.
- the enteral nutrition is performed.
- the therapy by an agent has been attempted.
- salazosulfapyridine, metronodazole, adrenal cortex steroids, immunosuppressants, 5-aminosalicylic acid (5-ASA) and the like are administered.
- an anti-TNF antibody has begun to be administered clinically. However, it can be said that the administration of these agents is insufficient yet for treating the Crohn's disease.
- TNF- ⁇ is an inflammatory cytokine produced by macrophages, macrophage lineage cells (Kupper cells), neutrophils, basophils, eosinophils, lymphocytes, NK cells, LAK cells, mast cells, bone marrow cells, fibroblasts, astrocytes, keratinocytes and the like, and has been recently demonstrated to be deeply involved in pathogenesis of many diseases including Crohn's disease. Therefore, it is believed that if the action of TNF- ⁇ can be inhibited, it becomes possible to treat those diseases.
- steroidal hormone agents and non-steroidal anti-inflammatory agents are applied to some inflammatory diseases. However, they have diverse action points and do not have an inhibitory action specific for TNF- ⁇ .
- the side effect of the steroid agent has become a medical problem.
- the treatment using an anti-TNF- ⁇ antibody and a soluble TNF- ⁇ receptor which are peptide macromolecules gives good clinical results in chronic rheumatoid arthritis and Crohn's disease, but sometimes induces serious infectious diseases including tuberculosis and sepsis, and deterioration of demyelinating disease. Occurrence of malignant tumors has been also reported. Additionally, the formation of a neutralization antibody has been reported, and thus they can not be said to be sufficient.

Description
- The present invention relates to an agent for treating or preventing an inflammatory bowel disease, comprising a particular amino acid(s). The present invention also relates to an agent for inhibiting TNF production, comprising a particular amino acid(s).
- An inflammatory bowel disease is a generic term for enteropathy with inflammation, and mainly includes ulcerative colitis and Crohn's disease. The ulcerative colitis is a diffuse non-specific inflammatory disease where large bowel mucosa or submucosa is affected and erosion or ulcer is often formed. Clinical symptoms are mucous and bloody stools, abdominal pain, blood stools, watery stools, fever, lack of appetite, malevolence, emesis and the like. As agents for treating the ulcerative colitis, salazosulfapyridine, adrenal cortex steroids, immunosuppressants, 5-aminosalicylic acid (5-ASA) and the like are used, but it can not be said that these agents are enough to treat the ulcerative colitis.
- Crohn's disease is an idiopathic chronic enteritis of unknown cause, and exhibits non-specific inflammatory symptoms in intestines from a small intestine to a large intestine. Its lesions are composed of granulomatous lesions with fibrosis and ulcer, and it is likely that the lesions appear in all gastrointestinal area from an oral cavity to an anus. The clinical symptoms of Crohn's disease include abdominal pain, general malaise, diarrhea, melena, occult blood positive, fever, weight loss, anemia, ileus symptom, abdominal tumor, malevolence, emesis and peritonitis symptom. Crohn's disease simultaneously causes various gastrointestinal and parenteral symptoms, e.g., intestinal stenosis, intestinal perforation, abdominal abscess and heavy hemorrhage which are serious conditions, in addition to nutritional disorder, and often requires procedures such as intestinal surgery. In Japan, a high calorie infusion or an enteral nutrition is performed for the purpose of improving the nutritional condition. In the high calorie infusion, a risk of bacterial translocation is increased. Thus, particularly for a long term, the enteral nutrition is performed. In addition, the therapy by an agent has been attempted. In the drug therapy, salazosulfapyridine, metronodazole, adrenal cortex steroids, immunosuppressants, 5-aminosalicylic acid (5-ASA) and the like are administered. Recently, an anti-TNF antibody has begun to be administered clinically. However, it can be said that the administration of these agents is insufficient yet for treating the Crohn's disease.
- TNF-α is an inflammatory cytokine produced by macrophages, macrophage lineage cells (Kupper cells), neutrophils, basophils, eosinophils, lymphocytes, NK cells, LAK cells, mast cells, bone marrow cells, fibroblasts, astrocytes, keratinocytes and the like, and has been recently demonstrated to be deeply involved in pathogenesis of many diseases including Crohn's disease. Therefore, it is believed that if the action of TNF-α can be inhibited, it becomes possible to treat those diseases. Currently, steroidal hormone agents and non-steroidal anti-inflammatory agents are applied to some inflammatory diseases. However, they have diverse action points and do not have an inhibitory action specific for TNF-α. Thus, it is likely to elicit harmful side effects. Particularly, the side effect of the steroid agent has become a medical problem. Furthermore, the treatment using an anti-TNF-α antibody and a soluble TNF-α receptor which are peptide macromolecules gives good clinical results in chronic rheumatoid arthritis and Crohn's disease, but sometimes induces serious infectious diseases including tuberculosis and sepsis, and deterioration of demyelinating disease. Occurrence of malignant tumors has been also reported. Additionally, the formation of a neutralization antibody has been reported, and thus they can not be said to be sufficient.

- Balb/c background IL-10 deficient mice were established from C57BL/6 background IL-10 deficient mice by back-crossing for seventh generations. Balb/c background IL-10 deficient mice spontaneously develop the colitis with aging and exhibit symptoms such as diarrhea. Spleen, mesenteric lymph nodes and sacral lymph nodes were collected from the IL-10 gene-deficient Balb/c mice (male) which had developed the colitis detected by observing the diarrhea symptoms. After preparing single cell suspensions, the cells at about 1×107 were injected intraperitoneally to Scid mice which were immunodeficiency mice (hereinafter the Scid mouse injected IP was referred to as an “experiment mouse”). Subsequently, a chow was changed to an experimental diet. As the experimental diet, a standard chow or those obtained by mixing the amino acids with the standard chow shown in the following Tables 1 to 5 were used. At a time point three weeks after cell transfer, the mice were killed, the colon was collected, the intestinal contents were washed out, and its weight was measured. A percentage of inhibiting a weight gain of the colon was calculated by the following formula.

- Extraction of total RNA
- The experimental diet obtained by mixing the amino acids shown in Table 6 with the standard chow was given to the experiment mice, and after three weeks, the colon was removed. A colon sample was homogenized with 500 μL of Isogen (Nippon Gene). The homogenate mixed with 100 μL of chloroform was centrifuged at 15,000 rpm at 4° C. and an aqueous layer was collected. An equivalent amount of 2-propanol was added thereto, which was then centrifuged at 15,000 rpm at 4° C. A resulting pellet was washed with 70% (v/v) ethanol, dried in air and dissolved in water treated with DEPC.
- Synthesis of cDNA
- All reagents used were from Invitrogen. 0.5 μg Of total RNA and 0.5 μg of oligo (dT) were dissolved in 12 μL of DEPC-treated water, heated at 70° C. for 10 minutes, and cooled on ice for one minute. Subsequently, 4 μL of 5×1st strand buffer, 1 μL of 10 mM dNTP mix and 2 μL of 100 mM DTT were added thereto. The mixture was reacted at 42° C. for 5 minutes. 1 μL (200 U) of SuperScriptII was added, and the mixture was reacted at 42° C. for 50 minutes and 70° C. for 15 minutes.

SYBR Green PCR Master Mix comprises SYBR Green and heat resistant DNA polymerase, and detects fluorescence generated by specifically binding SYBR Green to a double strand DNA amplified by PCR using ABI PRISM 7700 System. Gene expression amounts of the samples can be compared by comparing the numbers of PCR cycles at which a significant fluorescence signal is detected for the first time. The cDNA corresponding to 10 ng of total RNA was used as a template of the quantitative PCR, and n=2 or more per sample of measurements were performed. A forward primer and a reverse primer at each 7.5 μmol of each gene were added to 7.5 μL of SYBR Green PCR Master Mix (Applied Biosystems), and the total volume was made to be 15 μL with water. The PCR was performed by 40 cycles of the reaction at 95° C. for 10 seconds, 60° C. for 30 seconds and 72° C. for 30 seconds after reacting at 95° C. for 10 minutes. The sequences of the primers used for the quantitative RT-PCR are as follows.
