PD 0325901 （MEK抑制劑） PD-02/10/50

產品信息

MAPK屬于一種Ser/Thr蛋白激酶，可在多種不同的信號轉導途徑中充當一種共同的信號轉導成份，且在細胞周期調控中發揮重要的作用。MAPK信號通路包括：MAP激酶（MAPK）、MAPK激酶（MEK、MKK或MAPK 激酶）和MEK激酶（MEKK、MKKK或MAPK激酶激酶）。在哺乳動物機體中，已經發現五種不同的MAPK信號轉導通路。其中ERK1/2信號轉導通路調控細胞生長和分化，JNK和p38 MAPK信號轉導通路在炎癥與細胞凋亡等應激反應中發揮重要作用。

PD 0325901:
A selective inhibitor against purified MEK, exhibiting a Ki of 1 nM against activated MEK1 and MEK2. It has been shown that 1 µM PD0325901 combined with 3 µM CHIR99021 (2i) prevents cell differentiation and sustains self-renewal of murine embryonic stem cells. N-[(2R)-2,3-DIHYDROXYPROPOXY]-3,4-DIFLUORO-2-[(2-FLUORO-4-IODOPHENYL)AMINO]-BENZAMIDE
