Abstract:
본 발명은 NF-κB의 p65 서브유닛으로부터 유래된 작은 펩타이드 단편(small peptide fragments) 및 이를 포함하는 약학 조성물 또는 화장료 조성물을 제공한다. 상기 펩타이드는 NF-κB의 전사 촉진 기능을 조절함으로써 NF-κB 억제 활성을 갖는다. 상기 펩타이드들은 NF-κB 활성에 의해 발현이 유도되는 다양한 염증 매개분자의 발현을 억제하고 백혈구의 혈관외유출을 억제함으로써 항-염증 활성을 갖는다. 특히, 상기 펩타이드들은 피부 염증 및 피부 노화에 대한 우수한 억제활성을 갖는다. 또한, 상기 펩타이드들은 혈관신생 및 암세포의 바닥막 침윤을 억제함으로써 암세포의 성장과 전이에 대한 억제 활성을 갖는다.
Abstract:
The present invention provides a pharmaceutical composition for preventing or treating inflammation or skin aging which includes small peptide fragments derived from p65 subunits of NF-κB as an active ingredient. In addition, the present invention provides a cosmetic composition for improving inflammation or skin aging which includes the peptide fragments. The peptide suppresses expression of various inflammation mediated molecules in which expression is induced by activities of the NF-κB and suppresses extravasation of white blood cells. In addition, the cosmetic composition suppresses expression of MMP-1, TNF-α, and IL-1α which are inflammation mediators which are transcriptionally controlled by the NF-κB as the inflammation mediator which is increased by ultraviolet stimulation and suppresses production of PGE2 which is the inflammation mediated molecules and expression of COX-2 which is an enzyme which mediates the same so that the cosmetic composition has skin photoaging suppression activities.
