Abstract:
본 발명은 BLT2 억제제를 포함하는 자외선 보호용 조성물에 관한 것으로, 보다 상세하게는 자외선 조사에 의해 세포막 단백질인 BLT2, 이들의 리간드 및 이들의 합성효소 등이 과발현되어 활성산소종 생성 및 MAP 키나아제 활성화를 통한 세포사멸을 유도하며, 상기 단백질의 발현을 억제하는 억제제가 자외선으로부터 피부 또는 모발 등을 효과적으로 보호함을 규명함으로써 이를 피부보호제제, 피부염증제제, 자외선차단 피부보호제 등에 사용할 수 있다. 케라티노사이트, UVB, 세포사멸(Apoptosis), ROS, BLT2, Nox1, LTB4, 12(S)-HETE
Abstract:
PURPOSE: A novel inhibitor for blocking interaction of BLT2-G alpha i 3 is provided to block LTB4-BLT2-mediated signal transduction and to prevent or treat BLT2-associated immune diseases. CONSTITUTION: A novel inhibitor for blocking interaction of BLT2-G alpha I 3 contains one or more components selected from the group consisting of purpurine and chloranyl. The intracellular signal transduction of BLT2 is suppressed by bond of pupurine or chloranyl to BLT2. A composition for preventing or treating immune diseases is administered together with other active ingredients.
Abstract:
PURPOSE: A composition containing a BLT2 inhibitor for blocking UV ray is provided to suppress apoptosis and to protect skin or hair from UV ray. CONSTITUTION: A composition for blocking UV ray contains a BLT2 inhibitor as an active ingredient. The UV ray is UVB. The BLT2 inhibitor is LY255283, BLT2 siRNA, or BLT2 antibody. The BLT2 siRNA has a sequence of sequence number 1. A pharmaceutical composition for protecting skin or hair from UV ray contains the BLT2 inhibitor as an active ingredient. The pharmaceutical composition is used for preventing or treating skin inflammation, sensitive pigmentation, melanoma, or non-melanoma skin cancer. A cosmetic composition for protecting skin or hair form UV ray contains the BLT2 inhibitor as an active ingredient. The cosmetic composition further contains molecular or granular UV blocking agent, or mixture thereof.
Abstract:
PURPOSE: An inhibitor of leukotriene B4 receptor BLT2 is provided to suppress of possibility of metastasis of cancer cells and treat cancer such as breast cancer, prostate cancer, and pancreatic cancer. CONSTITUTION: An inhibitor of leukotriene B4 receptor BLT2 for treating human cancer suppresses expression and intracellular signal transduction of BLT2. The inhibitor is LY255283(1-[5-ethyl-2-hydroxy-4-[[6-methyl-6-(1/-/-tetrazol-5-yl)heptyl]oxy]phenyl]-ethanone). Human cancer is tumor in which BLT2 protein or oncogene RAS is overexpressed. A pharmaceutical composition for treating human cancer contains mixture of material which suppresses intracellular signal transduction or BLT2 expression and other anticancer drug as active ingredient.
