PD 0325901

Product Description

PD 0325901 is a potent MEK1 and MEK2 inhibitor. PD 0325901 inhibits MEK activity in mouse colon 26 cells (IC₅₀ = 0.33 nM). PD 0325901 inhibits the growth of melanoma cell lines in vitro and in vivo; induces G₁-phase cell cycle arrest and apoptosis in a mouse xenograft model. PD 0325901 also inhibits production of proangiogenic cytokines such as VEGF. PD 0325901 enhances generation of induced pluripotent stem cells (iPSCs). PD 0325901 in combination with Vitamin C sustains mouse ES cells at an undifferentiated and hypomethylated state. PD 0325901 promotes myelin recovery in drug-induced demyelination in vivo in mice model. Orally bioavailable. Used in protocols for the generation of CiPSCs from MEFs, induction of cortical neurons from hiPSCs, and culture of mESCs (see below).

For more information about how PD 0325901 may be used, see our protocols: Culturing Transcriptomically Distinct Pluripotent mESCs, Highly Efficient Generation of CiPSCs from MEFs, Accelerated Induction of Cortical Neurons from hiPSCs.
