摘要:
Nerve regeneration promoters containing compounds represented by the following general formula (1), salts thereof or prodrugs of the same: (1) wherein each symbol is as defined in the specification. The compounds represented by the general formula (1) inhibit nerve cell death and promote the formation of new nerve cells and nerve cell regeneration and also promote the repair and regeneration of nerve tissues and functions through neurite extension, because of serving as a stem cell (nerve stem cell, embryonic stem cell, bone marrow cell, etc.) proliferation/differentiation promoter, a nerve cell precursor proliferation/differentiation promoter, a neurotrophic factor activity enhancer, a neurotrophic factor-like substance or a neurodegeneration inhibitor. Furthermore, these compounds are useful in preparing cells for transplantation (nerve stem cells, nerve cell precursors, nerve cells, etc.) from a brain tissue, bone marrow, embryonic stem cells, etc. At the same time, these compounds promote the take, proliferation, differentiation and function expression of transplanted cells, which makes them useful as preventives and/or remedies for neurodegenerative diseases.
摘要:
The present invention relates to a substance specific to human PD-1 comprising a part that recognizes human PD-1, a part that recognizes a membrane protein in cell membrane of human PD-1-expressing cells, and linkers. Since the substance specific to human PD-1 selectively can recognize human PD-1 and a membrane protein on cell membrane of human PD-1-expressing cells and can transmit inhibitory signal of human PD-1, it is useful for therapy and/or prevention of diseases caused by immunopathy.
摘要:
A method of screening a substance inhibiting the onset of a disease in which an anti-myocardial troponin I autoantibody participates; a medicinal composition for treating a heart disease and a base material for treating a heart disease containing a substance produced by the above method; an apparatus for treating a heart disease in which an anti-myocardial troponin I autoantibody participates whereby the above antibody is removed; a method of constructing an animal for evaluating a heart disease which comprises administering an anti-myocardial troponin I autoantibody; a method of selecting a remedy for a heart disease with the use of the above animal; and a method of diagnosing dilated cardiomyopathy which comprises quantifying an anti-myocardial troponin I autoantibody. The above-described treatment apparatus whereby the anti-myocardial troponin I autoantibody is removed and the medicinal composition for treating a disease in which the antibody participate are useful in treating and/or preventing a heart disease.
摘要:
Compositions for cancer or infection treatment via immunopotentiation caused by inhibition of immunosuppressive signal induced by PD-1, PD-L1, or PD-L2 and therapies using them, immunopotentiative substrates included as the active ingredient, screening methods of the substrates for cancer or infection treatment, cell lines used for the screening methods, evaluation methods that selects the substrates for cancer treatment, and carcinoma cell transplanted mammals used for the evaluation methods. The compositions of the present invention that inhibits the function of PD-1,PD-L1, or PD-L2 are useful for cancer or infection treatment. The compositions of the present invention comprise an anti-PD-L1 antibody.
摘要:
[PROBLEM] The compound that selectively binds to BLT2 and the preventive and/or therapeutic drug for BLT2-mediated disease such as skin disease are needed. [MEANS] FOR SOLVING THE PROBLEMS] The present invention provides the compound with BLT2 binding activity, salt thereof, solvate thereof or prodrug thereof. Since the compound with BLT2 binding activity, particularly the compound represented by the formula (I)
, salt thereof, solvate thereof or prodrug thereof (symbols in formula have the same meanings as specification.) have BLT2 binding activity, it is useful for prevention and/or therapy of BLT2 mediated diseases, e.g., dermatosis, intestinal disease, HIV infection, acquired immunodeficiency syndrome, rejection to transplant, transplant rejection, graft-versus-host disease, autoimmune disease, allergic disease, inflammation, infection, ulcers, lymphoma, malignant tumor, leucaemia, arterial sclerosis, hepatitis, hepatic cirrhosis or cancer, etc.
wherein R 1 represents a hydrogen atom, etc., R 2 and R 3 each independently represents a hydrogen atom, optionally oxidized C1-4 alkyl group or optionally protected hydroxyl group, or R 2 and R 3 taken together represent optionally oxidized C2-5 alkylene group, R 4 represents an optionally oxidized C1-6 alkyl group, etc., R 5 represents an optionally oxidized C1-6 alkyl group, etc., R 6 represents an optionally oxidized C1-6 alkyl group, etc., m represents 0 or an integer from 1 to 3, n represents 0 or an integer from 1 to 4, and i represents 0 or an integer from 1 to 7.
摘要:
A compound represented by the general formula (I): (wherein R represents optionally protected hydroxy or oxo; indicates alpha configuration, beta configuration, or a mixture of these in an arbitrary proportion; n is an integer of 1 to 3; and m is an integer of 0 to 10, provided that two or more R 's are not bonded to the same carbon atom other than the terminal carbon atoms), a salt of the compound, or a prodrug of either. The compound represented by the general formula (I) is effective in, e.g., improving the function of astrocytes. It is useful as a preventive and/or therapeutic agent for brain infarction or nerve function disorders after brain infarction and for neurodegenerative diseases such as Parkinson's disease, Parkinson's syndrome, amyotrophic lateral sclerosis, and Alzheimer's disease.
摘要:
An agent for treating acute cerebral infarction, comprising (2R)-2-propyloctanoic acid or a salt thereof, which is used for administration after a lapse of time of from about 5 hours to about 72 hours from the onset of the disease is useful for treating acute cerebral infarction, since it safely improves acute cerebral infarction or accompanying symptoms in the patient of acute cerebral infarction, specifically in the patient of acute cerebral infarction defined as a score of 7 to 22 on NIH Stroke Scale.
摘要:
A compound represented by general formula (I):
a salt thereof, a solvate thereof, or a prodrug thereof wherein all symbols are as defined in the specification has an antagonistic activity against CXCR4 and is therefore useful as a preventive and/or therapeutic agent for CXCR4-mediated diseases, for example, inflammatory and immune diseases (for example, rheumatoid arthritis, arthritis, systemic erythematosus, retinopathy, macular degeneration, pulmonary fibrosis, transplanted organ rejection, etc.), allergic diseases, infections (for example, human immunodeficiency virus infection, acquired immunodeficiency syndrome, etc.), psychoneurotic diseases, cerebral diseases, cardiac /vascular disease(for example, arteriosclerosis, myocardial infarction, stenocardia, cerebral infarction, chronic arterial occlusive disease, etc.), metabolic diseases, and cancerous diseases (for example, cancer, cancer metastasis, etc.), a preventive and/or therapeutic agent for cancerous diseases or infections, or an agent for regeneration therapy.
