Abstract:
Provided are a 2-cyclopenten-1-one oxime derivative which inhibits the production of TNF-alpha or PEF4, its pharmaceutically acceptable salt, and a pharmaceutical composition containing the derivative for treating or preventing the TNF-alpha mediated disease. A 2-cyclopenten-1-one oxime derivative is represented by the formula(1), wherein R1 is a linear or branched C1-C10 alkyl group or a C3-C7 cycloalkyl group; and R2 is a substituted or unsubstituted aromatic group. Preferably the aromatic group of R2 is selected from a phenyl group, a pyridyl group, a naphthyl group, an indolyl group, a thienyl group, a benzo[b]thienyl group, a dibenzofuranyl group, or a thianthrenyl group.

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.
