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: Object The present invention provides a pharmaceutical composition for prophylaxis or treatment of hepatitis. Solution A pharmaceutical composition for prophylaxis or treatment of hepatitis, comprising a compound represented by the general formula (I): wherein R1 represents a C1-C4 alkyl group, R2 and R3 which are the same or different represent a hydrogen atom, a C1-C4 alkyl group, or a C1-C4 alkoxy group, X represents a sulfur atom or a nitrogen atom substituted by a methyl group, and n represents an integer of 3 or 4, or a pharmacologically acceptable salt thereof as an active ingredient.

Abstract: A pharmaceutical composition containing 1 or more PPAR regulators and 1 or more amino alcohol compounds of the formula (I): wherein R1 and R2, each represents hydrogen or alkyl; R3 represents C1-C6 alkyl or hydroxymethyl; R4 represents hydrogen, C1-C6 alkyl, alkoxy or halogen; R5 represents substituted phenyl; X represents vinylene (CH?CH), oxygen, sulfur or methylamino; Y represents a single bond, oxygen, sulfur or carbonyl; Z represents a single bond or C1-C8 alkylene; n represents 2 or 3; or pharmacologically acceptable salts thereof. The pharmaceutical composition is used to suppress rejection of organ transplants or skin grafts and to prevent or treat autoimmune diseases.
