Abstract:
PURPOSE: Carnosic acid, a derivative thereof, or a pharmaceutically acceptable salt thereof is provided to suppress elastase activation or matrix metalloproteinase-9 (MMP) expression, and to basically inhibit vital reaction mediated by the suppression. CONSTITUTION: An elastase activation inhibitor contains carnosic acid of chemical formula 1, a derivative thereof, or a pharmaceutically acceptable salt thereof as an active ingredient. The carnosic acid derivative is carnosic acid methyl ester or carnosic methyl alcohol. The carnosic acid, the derivative, or the pharmaceutically acceptable salt is derived from rosemary and/or sage. The inhibitor contains 0.0001-20 wt% of the active ingredient. An MMP expression inhibitor contains the carnosic acid, the derivative, or the pharmaceutically acceptable salt as an active ingredient. A composition for skin anti-aging contains the carnosic acid, the derivative, or the pharmaceutically acceptable salt as an active ingredient.
Abstract:
The present invention relates to a novel phenylacetic acid amide derivative compound, isomers thereof, pharmaceutically acceptable salt thereof, prodrug thereof, a hydrate or a solvate thereof, and a composition for skin whitening comprising the same. The novel compound or the like has excellent skin whitening effect.
Abstract:
The present invention provides a novel pseudo-ceramide compound represented by Chemical Formula 1, an isomer thereof, a pharmaceutically acceptable salt thereof, a pro-drug thereof, a hydrate thereof, and a solvate thereof. [Chemical Formula 1] (In Chemical Formula 1, R is a C9 to 17 saturated or unsaturated aliphatic chain, and R′ is an amino group or an alkoxy group having a C10 to 18 saturated aliphatic chain.) According to the present invention, the novel pseudo-ceramide compound has a skin protecting effect by having excellent stability, dissolubility, and skin moisturization, so that the novel pseudo-ceramide compound can be used as an active ingredient for protecting the skin from external stimuli without side effects, preventing the skin from damage, and recovering damaged skin. Accordingly, the novel pseudo-ceramide compound can be used as a skin-moisturizing composition for external application on skin, a cosmetic composition, or a pharmaceutical composition.
Abstract:
PURPOSE: A skin irritation relieving agent containing carnosic acid or a derivative thereof is provided to suppress release of IL-8(interleukin-8), MCP-1(monocyte chemotactic protein-1), and IL-6(interleukin-6), and to relieves skin irritation due to retinoid or surfactant. CONSTITUTION: A skin irritation relieving agent contains carnosic acid denoted by chemical formula 1, a derivative thereof, or pharmaceutically acceptable salt thereof as an active ingredient. The skin irritation relieving agent relieves inflammation, skin dryness, erythema, horny substance, itching, or burning sensation. The skin irritation is caused by retinoid or surfactant of an external use skin formulation. The retinoid is selected from the group consisting of retinol, retinal, and retinoic acid.
Abstract:
PURPOSE: A benzoic acid amide compound is provided to have excellent a skin-whitening effect without side effects by suppressing melanin generation and decreasing tyrosinase activity. CONSTITUTION: A benzoic acid amide compound, an isomer thereof, pharmaceutically-acceptable salt thereof, a prodrug thereof, a hydrate thereof, or a solvate thereof is represented by chemical formula 1. In the chemical formula 1: each of R1, R3, and R4 is independently selected from hydrogen, hydroxy, C1-C5 alkoxy, C3-C6 cycloalkoxy, aryloxy, and C1-C15 haloalkoxy; R2 is selected from hydrogen, C1-C5 alkyl, C3-C6 cycloalkyl, aryl, and C1-C5 haloalkyl; and n is an integer from 1-5.
