Abstract: Provided are a novel compound having CDK8 and/or CDK19 inhibitory activity, and a production method for Tregs. The treatment of T cells with a CDK8 and/or CDK19 inhibitor induces Foxp3 in the T cells. Foxp3+ T cells can be induced by treating Foxp3? T cells with the CDK8 and/or CDK19 inhibitor in vitro. Thus, Tregs can be induced.

Abstract: Provided is a pharmaceutical for preventing or treating an ophthalmic disease associated with intraocular neovascularization and/or increased intraocular vascular permeability. The inventors of the present invention have made investigations on a pharmaceutical for preventing or treating an ophthalmic disease associated with intraocular neovascularization and/or increased intraocular vascular permeability, and have confirmed that a selective S1P receptor agonist having agonist activity at an S1P1 receptor has an intraocular neovascularization-reducing action and an intraocular vascular permeability-reducing action, thus completing the present invention.

Abstract: The present invention provides a highly effective substance having a filaggrin production-promoting action. The present invention also provides a therapeutic agent useful for treating a skin disease, in particular, atopic dermatitis associated with reduced filaggrin production. As a result of intensive studies on a filaggrin production promoter, it has been found that A) an N-quinolylbenzamide derivative (Compound 1), B) ivermectin (Compound 2), or C) a phenylalaninamide derivative (Compound 3) promotes production of filaggrin in skin and satisfactorily improves a water retention ability and barrier function of the stratum corneum. The present invention relates to a filaggrin production promoter containing a certain N-quinolylbenzamide derivative or a pharmaceutically acceptable salt thereof as an active ingredient.

Abstract: The present invention relates to a prophylactic and/or therapeutic agent for an allergic disease which contains a compound having an agonistic activity to EP3 receptor that is one of the prostaglandin E2 receptor subtypes. More specifically, a compound having an agonistic activity to EP3 receptor is effective in therapy of an allergic respiratory disease such as bronchial asthma, pediatric asthma, allergic asthma, or atopic asthma, and a selective agonistic compound can be expected to induce a more remarkable therapeutic effect.

Abstract: The treatment and/or prophylactic drugs of post-traumatic stress disorder (PTSD) containing compounds (EP1 agonists), which activate EP1 receptor that is subtype of prostaglandin E2 receptor, as an active ingredient. EP1 agonists such as (13E)-(11?,15S,17S)-2,5-ethano-6,9-dioxo-11,15-dihydro-17,20-dimethylprosta-13-enoic acid, PGE1, or PGE2, etc. are useful for the treatment of post-traumatic stress disorder (PTSD).

Abstract: An objective of the present invention is to provide an activated Rho protein target protein derived from a human and a gene coding for the same. The present invention provides a protein derived from a human and a derivative thereof which has the following characteristics: (1) having activated Rho protein binding activity, (2) having profilin binding activity, (3) the gene coding for the protein being located at q31.2 of chromosome 5, and (4) having a molecular weight of about 150 kDa as measured by SDS-PAGE. Respiratory tract hypersensitivity, bronchial asthma, acute myelocytic leukemia (AML) and myelodysplasia syndrome (MDS) can be diagnosed using the nucleotide sequence coding for this protein.

Abstract: The object of the present invention is to provide a target protein for the activated Rho protein. The present invention is a protein having the activated Rho protein binding activity and protein kinase activity, or derivatives thereof. The molecular weight of the protein is about 160 kDa as measured by SDS-PAGE. The protein kinase activity of the protein is enhanced when it binds to the activated Rho protein.

Abstract: Disclosed are (1) a protein capable of receiving PGE, (2) a recombinant DNA coding for said protein, (3) a vector having said DNA, (4) a transformant carrying said vector, and (5) a method for producing said protein wherein said transformant is cultured in a culture medium, the protein being useful not only in cloning other PGE receptor genes, clarifying the structure of PGE receptors and elucidating the function of PGE, but also in searching for PGE antagonists and agonists and so on.
