摘要:
The present invention provides an agent for preventing or relapse-preventing, treating or ameliorating gastroesophageal reflux disease, in which existing treatment is not effective. 4-[({6-[Isobutyl(1,3-thiazol-2-ylsulfonyl)amino]-2,3-dihydro-1H-inden-5-yl}oxy)methyl]-3-methyl benzoic acid, a salt thereof or a prodrug thereof is effective in the prevention or relapse prevention, treatment or amelioration of gastroesophageal reflux disease.
摘要:
As a substance which pharmacologically regulates the function of a cell surface functional molecule, a substance which has specificity and an activity or efficacy equal or superior to an antibody and does not require an advanced production technique and facility for application thereof to a pharmaceutical product has been demanded. The invention relates to a multimer of an extracellular domain of a cell surface functional molecule, particularly a tetramer of an extracellular domain of PD-1 or PD-L1. Further, the invention relates to an application of such a tetramer as a preventive and/or therapeutic agent for cancer, cancer metastasis, immunodeficiency, an infectious disease or the like and an application of PD-1 or PD-L1 as a testing or diagnostic agent or a research agent for such a disease.
摘要:
The present invention provides compounds of the general formula (I), their salts and N- oxides, and solvates and prodrugs thereof (wherein the characters are as defined in the description). The compounds of the general formula (I) are inhibitors of Factor XIa, so that they are useful in the prevention of and/or therapy for thromboembolic diseases.
摘要:
The purinone derivative 6-amino-9-[(3R)-1-(2-butynoyl)-3-pyrrolidinyl]-7-(4-phenoxyphenyl)-7,9-dihydro-8H-purin-8-one hydrochloride has Btk-selective inhibitory activity and, in addition to having excellent metabolic stability, it is a compound that exhibits a high level of solubility and absorption with respect to the free base and can be crystallized, hence it can serve as a therapeutic agent for diseases involving B cells and mast cells.
摘要:
The present invention provides a compound of which active form is represented by a formula (A). and which can be injected into a joint cavity which is an affected part of disorders and can be accumulated in the joint cavity to exert the pharmacological effect thereof in a sustained manner, for the purpose of ameliorating cartilage disorders without developing any side effect. A compound according to the present invention, which is represented by a formula (I):
(wherein all of symbols are as defined in the description), is a compound that can achieve the above-mentioned purpose. This compound does not exhibit any side effect on the cardiovascular system even when the compound is administered in an effective amount for exhibiting a cartilage regeneration activity, and is therefore extremely useful as a safe and effective preventive and/or therapeutic agent for cartilage disorders. Since a suspension produced using this compound can be injected without requiring the incision of the affected part, it can reduce the burden on patients, and is extremely useful as a medicinal agent.
摘要:
The present invention relates to use of an antagonist of BIR1 (B cell immunoglobulin receptor 1) related to the present invention, a method for screening the antagonist, in addition to subtype polypeptides of BIR1, the polynucleotide encoding them and antibodies for the polypeptides. BIR1 functions as an immunosuppressive receptor, and the antagonist of BIRI has immunopotentive activity, which is able to use for preventing and/or treating a cancer, an immunodeficiency disease or an infectious disease.
摘要:
The present invention provides a method that allows production of stereospecific and asymmetrical five-membered ring-containing compounds serving as synthetic intermediates for formation of five-membered rings of prostaglandins and the like, with high yield and excellent stereoselectivity in terms of diastereoselectivity and enantioselectivity in a short process without requiring troublesome procedures such as optical resolution. The method for producing a five-membered ring-containing compound includes a cyclization step of condensing and cyclizing an α, β-unsaturated nitro compound represented by the following chemical formula (I) with a 1,4-butanedione compound, in the presence of a catalyst formed by a compound having a pyrrolidine ring and an optically active α-carbon relative to the nitrogen on the ring, in a water-insoluble organic solvent and/or a non-oxygen atom-containing water-soluble organic solvent so as to produce the five-membered ring-containing compound represented by the following chemical formula (II).
