Background

PD 0325901 is a potent and selective non-ATP competitive MEK inhibitor. This small molecule is highly effective at inhibiting cell growth and proliferation in various cancer cells (1). The potency of PD 0325901 has been illustrated by the inhibition of ERK phosphorylation in mouse and human cell models with an IC50 of 0.33 nM and between 20-50 nM, respectively (1,2). PD 0325901 increases the self-renewal of mouse embryonic stem cells (mESCs) by enhancing the expression of pluripotency genes and acts as an antagonist for retinoic acid (RA) induced cell differentiation (3).
