摘要:
The present invention provides a method for inducing differentiation of cardiomyocytes efficiently and selectively from stem cells. A method for inducing differentiation of cardiomyocytes from pluripotent stem cells, which comprises: (i) culturing the pluripotent stem cells in a culture medium containing no substance that promotes activation of the canonical Wnt signaling pathway during the time period between initiation of differentiation induction and 24 hours before the period of elevated canonical Wnt gene expression; and then (ii) culturing the pluripotent stem cells in a culture medium containing a substance that promotes activation of the canonical Wnt signaling pathway during a time period of 24 to 96 hours, starting from 24 to 0 hours before the period of elevated canonical Wnt gene expression.
摘要:
It is intended to provide a method for significantly improving the bioavailability of orally administered sapropterin hydrochloride which is used as a therapeutic agent for BH4 responsive hyperphenylalaninemia and a preparation for oral administration or a preparation for oral intake with improved bioavailability. It is a preparation in which the bioavailability of sapropterin hydrochloride has been improved characterized by containing sapropterin hydrochloride and an absorption promoter comprising an organic carboxylic acid having a plurality of carboxyl groups in its molecule, wherein the organic carboxylic acid containing a plurality of carboxyl groups in its molecule is selected from tartaric acid, citric acid, malic acid, or an optically active substance, a racemic compound, an anhydride or a hydrate thereof or a mixture thereof and the addition amount thereof is 0.1 to 100 times the weight of sapropterin hydrochloride.
摘要:
The present invention provides a novel therapeutic agent for skin injuries and a skin regeneration accelerator. The therapeutic agent for skin injuries and the skin regeneration accelerator containing a substance acting on a growth hormone secretagogue receptor or a pharmaceutically acceptable salt thereof as an active ingredient.
摘要:
The growth of myocardial cells is induced by expressing cycline and CDK in the myocardial cells and regulating the function or action of a Cip/Kip protein, or by inhibiting the production of a Cip/Kip protein. Among the Cip/Kip family proteins, it is preferable to regulate the function of p27Kip1 or inhibiting the production thereof. As a recombinant vector to be used therefor, it is intended to provide a vector having: (1) a cyclin gene; (2) a cyclin-dependent kinase gene and (3) one or more members selected from the group consisting of a gene encoding a factor inhibiting the function or action of a Cip/Kip protein and nucleic acid sequences inhibiting the production of Cip/Kip family proteins.
摘要:
A pharmaceutical composition for nasal administration exhibits an improved bioavailability of a biologically active polypeptide, the active ingredient of the pharmaceutical composition. Specifically, the composition is prepared by uniformly dispersing and embedding a biologically active acidic polypeptide having an isoelectric point of 7 or lower on the surfaces of a polyvalent metal compound carrier with the help of an additive capable of dispersing and embedding the polypeptide on the surfaces of the carrier. The polyvalent metal compound carrier is a metal compound with a valent of 2 or higher that is either insoluble or little soluble in water, examples being aluminum compounds, calcium compounds, magnesium compounds, silicone compounds, iron compounds, and zinc compounds.
摘要:
Preventive or therapeutic drugs, which inhibit the progression of eosinophilia-related diseases while preventing the progression of various complications, and are so safe by virtue of their being free from adverse effects as to bring about enhancement in the quality of daily life of a patient. Specifically, preventive or therapeutic drugs for eosinophilia-related diseases containing chymase inhibitors as the active ingredient, wherein the chymase inhibitors are quinazoline derivatives of the general formula (I) or pharmacologically acceptable salts thereof: (I)
摘要:
Preventive or therapeutic drugs for dermatitises accompanied with dimorphic inflammatory reactions and those caused by repeated exposure to antigens, which inhibit the progression of such dermatitises and are so safe by virtue of their being free from adverse effects as to bring about enhancement in the quality of daily life of a patient. Specifically, remedies for the above dermatitisescontaining chymase inhibitors as the active ingredient, wherein the chymase inhibitors are quinazoline derivatives of the general formula (I) or (II) or pharmacologically acceptable salts thereof.
摘要:
It is intended to provide agents promoting the proliferation and/or differentiation of hematopoietic stem cells and/or hematopoietic precursor cells which are useful as remedies for diseases induced by the insufficient proliferation and/or differentiation of hematopoietic stem cells and/or hematopoietic precursor cells, in particular, diseases associated with a diffuse decrease in hematopoietic cells and/or hematopoietic hypofunction. The above problem is solved by providing agents for promoting the proliferation and/or differentiation of hematopoietic stem cells and/or hematopoietic precursor cells which contain as the active ingredient cofilin.
摘要:
NF-λB inhibitors containing as the active ingredient benzoquinone derivatives represented by general formula (I), hydroquinone compounds thereof or salts of the same, wherein R1, R2 and R3 independently represent each H, C1-5 alkyl or C1-5 alkoxy; R4 represents H, hydroxy-methyl, alkyl or optionally esterified or amidated carboxy; Z is represented by formula (A); and n is from 0 to 6.
