Abstract: An object of the present invention is to provide a sustained release composition containing SDF-1. The present invention provides a sustained release composition containing (1) SDF-1 and (2) a hydrogel containing modified gelatin having a carboxyl group and/or a sulfo group. Since the composition can release SDF-1, a chemokine which is a capable of promoting accumulation of vascular progenitor cells in vivo, in the sustained manner, it can be useful for treatment and/or suppression of symptom progression of ischemic disease or bone disease, as pharmaceutical preparations in various formulations.

Abstract: It relates to an endogenous repair factor production accelerator which comprises one or at least two selected from prostaglandin (PG) I2 agonist, EP2 agonist and EP4 agonist. Since prostaglandin (PG) I2 agonist, EP2 agonist or EP4 agonist has various endogenous repair factor production accelerating action, angiogenesis acceleration action and stem cell differentiation induction action, it is useful as preventive and/or therapeutic agents for ischemic organ diseases (e.g., arteriosclerosis obliterans, Buerger disease, Raynaud disease, myocardial infarction, angina pectoris, diabetic neuropathy, spinal canal stenosis, cerebrovascular accidents, cerebral infarction, pulmonary hypertension, bone fracture, Alzheimer disease, etc.) and various cell and organ diseases.

Abstract: A compound represented by formula (I), wherein R1 represents a hydrogen atom, etc., R2 and R3 each independently represents a hydrogen atom, optionally oxidized C1-4 alkyl group or optionally protected hydroxyl group, or R2 and R3 taken together represent optionally oxidized C2-5 alkylene group, R4 represents an optionally oxidized C1-6 alkyl group, etc., R5 represents an optionally oxidized C1-6 alkyl group, etc., R6 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.

Abstract: Compounds represented by general formula (I) (all of the symbols in the formula conform to the definitions in the Description) are compounds that, in addition to having a Btk-selective inhibitory activity, exhibit an excellent metabolic stability and can avoid hepatotoxicity or the like, and as a consequence can provide safe therapeutic agents for diseases in which B cells or mast cells participate.

Abstract: Since a compound represented by formula (I) wherein all of the symbols are the same as defined in the specification, a salt thereof, a solvate thereof, a prodrug thereof, a mixture with a diastereomer thereof in an arbitrary ratio, or a cyclodextrin clathrate thereof have a contracting activity of bladder detrusor and a relaxing activity of urethral sphincter, they can ameliorate bladder contraction dysfunction and/or urethral relaxation dysfunction, and for example, are effective for underactive bladder. Additionally, the compound of the present invention has little risk of side effects on the urinary system, the circulatory system and the digestive system, and exhibits excellent pharmacokinetics, such as oral absorbability etc. Therefore, the compound of the present invention is useful as a superior agent for preventing, treating and/or ameliorating underactive bladder.

Abstract: An EP2 agonist which may have an EP3 agonistic effect has an effect of regenerating and/or protecting nerves, and is therefore useful as a therapeutic agent for a disease of the peripheral nervous system, such as a lower or upper motor neuron disease, a nerve root disease, plexopathy, thoracic outlet compression syndrome, peripheral neuropathy, neurofibromatosis and neuromuscular transmission disease. An EP2 agonist which has an EP3 agonistic effect is a safe and effective agent for the regeneration and/or protection of nerves which has little influence on the circulatory system.

Abstract: A compound represented by formula (I), a salt thereof, an N-oxide thereof, a solvate thereof or a prodrug thereof: (wherein each symbol is as defined in the description.) The compounds represented by formula (I) has the antagonistic activity against CCR5, so they are useful in preventing and/or treating CCR5-related diseases, for example, various inflammatory diseases (asthma, nephritis, nephropathy, hepatitis, arthritis, rheumatoid arthritis, rhinitis, conjunctivitis, inflammatory bowel disease such as ulcerative colitis, etc.), immunological diseases (autoimmune diseases, rejection in organ transplantation (rejection of graft of solid organ, rejection of graft of pancreatic islet cells in therapy for diabetes, graft-versus-host disease, etc.), immunosuppression, psoriasis, multiple sclerosis, etc.), infectious diseases (infection with human immunodeficiency virus, acquired immunodeficiency syndrome, infection with RSV, etc.

Abstract: 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 BIR1 has immunopotentive activity, which is able to use for preventing and/or treating a cancer, an immunodeficiency disease or an infectious disease.

Abstract: A compound represented by formula (I), wherein R1 represents a hydrogen atom, etc., R2 and R3 each independently represents a hydrogen atom, optionally oxidized C1-4 alkyl group or optionally protected hydroxyl group, or R2 and R3 taken together represent optionally oxidized C2-5 alkylene group, R4 represents an optionally oxidized C1-6 alkyl group, etc., R5 represents an optionally oxidized C1-6 alkyl group, etc., R6 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.
