NOVEL 3-CHLORO-5-SUBSTITUTED-QUINOXALINE-2-AMINE DERIVATIVES AND PHARMACEUTICALLY ACCEPTABLE SALT THEREOF, METHOD FOR PREPARATION, THERAPEUTIC AGENT FOR ANTIINFLAMMATORY DISEASE INDUCED BY SPC ACTIVITY CONTAINING 3-CHLORO-5-SUBSTITUTED-QUINOXALINE-2-AMINE DERIVATIVES AS AN EFFECTIVE INGREDIENT

摘要

Provided are a 3-chloro-5-substiuted-quinoxalin-2-amine derivative represented by the following Chemical Formula 1, a pharmaceutically acceptable salt thereof, a method for preparation thereof, and a use thereof as an effective ingredient in a therapeutic agent for inflammatory disease induced by activity of sphingosyl phosphorylcholine (SPC) receptor. The 3-chloro-5-substiuted-quinoxalin-2-amine derivative of the present invention has been confirmed to have superior inhibition activity against SPC receptor in an animal experiment using human-derived endothelial cells and mice. Thus, a therapeutic agent for inflammatory disease containing the 3- chloro-5-substiuted-quinoxalin-2-amine derivative or a pharmaceutically acceptable salt thereof as an effective ingredient may be useful for treating inflammation, itching or skin infection associated with atopic dermatitis or other disease induced by activity of SPC receptor.
