Benefits of technology

[0007] In view of the foregoing situations, the present inventors have made extensive studies and as a result, found that monoclonal antibodies against macrophage migration inhibitory factors (MIF), low molecular compounds capable of binding to MIF and the like prevent serum depletion-induced cell death in rat primary cardiomyocytes. Furthermore, the inventors have found that low molecular compounds capable of binding to this MIF prevent myocardial cell death induced by doxorubicin or HMG-CoA reductase inhibitors, cartilage cell death induced by NO, etc. and have also found that the low molecular compounds increase expression of genes under control of Antioxidant response element (ARE). Based on these findings, the inventors have continued further investigations and come to accomplish the present invention.

Problems solved by technology

However, the relationship between MIF and cell death is unknown except for the mouse B cell line, and moreover, there is no report on mechanism of cell death in which MIF is involved.

reference example 1

2-(2-Pyridyl)-4H-1,3-benzothiazin-4-one (Compound 1)

[0122]

[0123] Methyl thiosalicylate (1.6 g, 9.51 mM) and 2-cyanopyridine (1.0 g, 9.60 mM) were dissolved in toluene (2 ml), and triethylamine (2 ml, 14.4 mM) was added to the solution. After heating for 8 hours under reflux, toluene was removed by distillation. Ethanol was added to the residue and the precipitates were taken out by filtration to give crude crystals (1.7 g). The crude crystals were purified by silica gel column chromatography (hexane: chloroform=5:1→chloroform) to give the title compound as crystals (1.0 g, 43.4%).

[0129]

[0130] Methyl thiosalicylate (1.8 g, 10.7 mM) and 3-cyanopyridine (1.1 g, 10.56 mM) were dissolved in toluene (5 ml), and triethylamine (2 ml, 14.4 mM) was added to the solution. After heating for 48 hours under reflux, the same procedures as in REFERENCE EXAMPLE 1 were carried out to give the title compound as crystals (1.1 g, 43.4%).

Abstract

The cell death inhibitor comprising a substance capable of binding to macrophage migration inhibitory factor is useful as a preventive / therapeutic agent for, e.g., heart diseases, neurodegenerative diseases, cerebrovascular diseases, central nervous infections, traumatic diseases, demyelinating diseases, bone / joint diseases, kidney diseases, liver diseases, myelodysplastic diseases, arteriosclerosis, diabetes, pulmonary hypertension, sepsis, inflammatory bowel diseases, autoimmune diseases, failure accompanying rejection in organ transplantation, AIDS, cancer, etc.

Description

TECHNICAL FIELD [0001] The present invention relates to a cell death inhibitor, screening for the cell death inhibitor, and the like. BACKGROUND ART [0002] From the nature of processes to death, cell death is categorized into two types, necrosis and apoptosis. Necrosis is accidental cell death that accidentally occurs due to physical / chemical factors, etc. In contrast, apoptosis is cell death deeply involved in morphogenesis during the developmental process, tissue formation, maintenance of homeostasis, biological defense, etc. to play a critical role in supporting the individual's life, and the process is regulated by a gene. Congenital or acquired disorders of these cell death processes excessively induce or prevent cell death to cause dysfunctions of various organs, leading to diseases (SAISHIN-IGAKU, 54, 825, 1999). [0003] In recent years, it has been revealed that these types of cell death are deeply committed to the development or progress of various diseases (R. Sanders Willi...
