General description

PD-0325901 is a highly effective oral small-molecule inhibitor that targets both mitogen-activated protein kinase kinase 1 (MEK1) and MEK2. It is a selective, non-ATP-competitiveinhibitor of these two MEK isoforms. This cell-permeable benzamide compound is a selective non-competitive inhibitor of MAPKK/MKK, effectively blocking cellular Erk1/2 phosphorylation. In serum-starved HeLa cells, it achieves over 90% inhibition after serum stimulation, while in C26 cells, it reduces phosphorylation by 50% at inhibitor concentrations of 25 nM and 0.33 nM, respectively. The compound exhibits minimal to no effect on Erk1/2 activity ora panel of 66 other kinases, even at concentrations as high as 10 µM in cell-free kinase assays. PD-0325901 has demonstrated oral bioavailability inmice, successfully suppressing both tumor growth and Erk phosphorylation in BRAF(V600E)-expressing SKMEL28 cell-derived tumors in vivo.

Application

PD 0325901 has been used as:·

  • a supplement in induced pluripotent stem cells (iPSC) medium to culture MEF feeder layers with reprogrammed cells
  • mitogen-activated protein kinase kinase1/2 (MEK1/2) inhibitor to treat the cells to identify G1 phase cells that had crossed the restriction point in the cell cycle
  • Mek1/2 inhibitor to block the Ras-Erk1/2 signaling pathwayto investigate the role of fibroblast growth factor (Fgf) signaling in the specification of endoderm progenitors during embryonic development
