Abstract: Provided are heterocyclic compounds, having effects of treating and preventing inflammatory diseases and treating skin wounds, and particularly, exhibiting effects of recovering disrupted skin barriers, mitigating inflammation, and pruritus. Also, a composition containing the compound as an effective component can be used to mitigate various inflammatory diseases and protease activated receptor-2 (PAR-2)-overexpressed diseases, and can be particularly used as a composition having an anti-inflammatory function in inflammatory skin diseases including atopic dermatitis and the like, by inhibiting PAR-2 activity.

Abstract: Disclosed is a compound having an acceleration effect on the secretion of human ?-defensin, LL-37, which is a human-derived anti-microbial peptide, a method for preparing same, and a composition for accelerating the secretion of anti-microbial peptide having same as an active ingredient, and the compound and the composition using same of the present invention enhance the anti-microbial effect and the immunity control effect that the anti-microbial peptide has in the body by accelerating the secretion of the anti-microbial peptide in the body.

Abstract: The heterocyclic compound according to the present invention may treat and prevent inflammatory diseases and heal skin wounds, and particularly, have effects of recovering damaged skin barrier, reducing inflammation and pruritus in inflammatory skin diseases. In addition, the composition containing the compound according to the present invention as an active ingredient may be used to alleviate various inflammatory diseases and diseases in which PAR-2 is excessively expressed, and particularly, the composition may inhibit activity of PAR-2 in skin, such that the composition may be used as a composition having anti-inflammatory function in inflammatory skin diseases including atopic dermatitis, or the like.

Abstract: Disclosed herein is the use of a non-natural compound represented by the following formula 1 as an activator of the peroxisome proliferator activated receptor-? (PPAR-?) which shows an anti-inflammatory effect on inflammatory skin diseases. The PPAR-? activator increases the expression of PPAR-? in the skin to enhance various physiological effects of PPAR-?, that is, the anti-inflammatory effect caused by inhibiting the activity of transcription factors such as the nuclear factor ?K (NF-?K) that induces inflammatory reactions, the effect of improving the epidermal permeability barrier function of the skin, and the effect of promoting the terminal differentiation of epidermal keratinocytes. Thus, the PPAR-? activator is useful for the treatment, alleviation or amelioration of skin diseases such as acne, seborrheic dermatitis, viral skin diseases, urticaria, pruritus, viral infectious diseases and contact dermatitis.
