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:
PURPOSE: A composition containing NADPH oxidase complex protein and/or diphenylene iodonium and/or derivative thereof is provided to treat and diagnose cancer. CONSTITUTION: A composition for preventing and treating cancer contains therapeutically effective amount of diphenylene iodonium, derivative thereof, or pharmaceutically acceptable salt thereof as an active ingredient. The therapeutically effective amount is 1mg/kg to 1000 mg/kg. The composition is administered by combining with an anti-cancer drug such as cisplatin, taxol, taxotere, doxorubicin, etoposide, gleevec, arimidex, tamoxifern, epirubicin, adriamycin, or valstar.
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.
Abstract:
PURPOSE: A method for preparing recombinant plasmid using heme oxidase-1 gene is provided to screen natural products with anti-obesity and/or anti-inflammatory functions. CONSTITUTION: A recombinant plasmid is used for suppressing the expression of heme oxidase-1 gene. A plasmid vector contains an RNA promoter. The hame oxidase-1 gene has a base of sequence number 1. A base for inducing hairpin structure is a base of sequence number 2 or 3. A method for producing adipocytes which suppresses heme oxidase-1 gene expression comprises a step of transduction of the recombinant plasmid to adipocyte cell line. A method for detecting an anti-obesity candidate from a natural product comprises: a step of treating the natural product to the adipocytes; a step of measuring the expression level of the heme oxidase-1 gene; and a step of selecting the natural product as an anti-obesity candidate material when the expression of heme oxidase-1 gene is reduced.
