Background:

PD0325901is a specific inhibitor of mitogen-activated protein kinase MEK. PD0325901 is a small molecular with the formula of C₁₆H₁₄F₃IN₂O₄and Molecular Weight of 482. MEK is a key component of the RAS/RAF/MEK/ERK signaling pathway that is frequently activated in human tumors, and MEK/ERK regulates cell proliferation, survival, and differentiation in response to extracellular signals. PD0325901 effectively reduces P-ERK levels and cell growthin vitro, and inhibits tumor growth in mouse modelin vivo
