Disclosed herein are 2,4-disubstituted-5-aminocarbonyl-1,3-thiazole derivatives, a preparation method thereof, and a therapeutic agent for treating inflammatory diseases induced by SPC, which contains the derivative as an active ingredient. The anti-inflammatory effect of the 2,4-disubstituted-5-aminocarbonyl-1,3-thiazole derivatives was analyzed through a test employing human dermal cells and an animal test using mice and, as a result, it was found that the derivatives showed excellent inhibitory activity on SPC receptor compared to thiazole derivatives known in the prior art. Thus, the 2,4-disubstituted-5-aminocarbonyl-1,3-thiazole derivatives or pharmaceutically acceptable salts thereof are useful as active ingredients in therapeutic agents for treating inflammatory diseases, such as inflammation, pruritus and skin infection, which appear in atopic dermatitis and other diseases induced by SPC activity.
