Abstract: Thermosensitive fine particles of the present invention include a side chain crystal polymer which is crystallized at a temperature lower than a melting point and which exhibits fluidity at a temperature equal to or more than the melting point. The side chain crystal polymer may include, as a monomer component, a (meth)acrylate having a straight-chain alkyl group having 14 or more carbon atoms. A mean particle diameter of the fine particles may be 0.1 to 50 ?m. The thermosensitive fine particles may include no organic solvents.

Abstract: by screening using a high-throughput evaluation system relating to the promotion of the extracellular secretion of trimers of the causative proteins COL4A3/A4/A5, which decreased in the renal tissue of patients with Alport syndrome (AS), it was found that cyclosporin A has an effect of promoting extracellular secretion of trimers of type-IV collagen. From further studies, it was found that Alisporivir and NIM258, which do not inhibit calcineurin, also have an action to promote extracellular secretion of type-IV collagen. Furthermore, the present inventors have found that these actions are based on the cyclophilin D inhibitory mechanism, and have found a radical therapeutic agent for AS by inhibition of cyclophilin D. The present invention provides a composition and an AS therapeutic/prophylactic drug, which contain a cyclophilin D inhibitor as an active ingredient, for promoting the secretion of collagen trimers in cells having a mutated type-IV collagen gene.

Abstract: An object of the present invention is to provide a combination therapy in which an antitumor effect is enhanced as compared to when a Trk inhibitor or any of various kinase inhibitors is administered alone. A Trk inhibitor, particularly, a compound represented by General Formula (I): wherein all symbols have the same meanings as symbols described in this specification, a salt thereof, an N-oxide thereof, a solvate thereof, or a prodrug thereof is useful as an active ingredient of a cancer therapeutic agent used in combination with one or more drugs selected from the group consisting of an MEK inhibitor, a CDK4/6 inhibitor, an EGFR inhibitor and a JAK1/2 inhibitor.
