PD 0325901 Usage And Synthesis

Description

PD 325901 (391210-10-9) is a selective non-ATP competitive MEK inhibitor (IC50 = 0.33 nM).1 Inhibits growth and/or proliferation of a variety of cancer cells.2 Enhances self-renewal of embryonic stem cells.3 In combination with vitamin C, synergistically induces hypomethylation of mouse embryonic stem cells.4 In combination with CHIR-99021 and A83-01 induces generation of ground state iPS cells from human and rat somatic cells.5

Chemical Properties

White to Off-White Solid

Uses

PD 0325901 has been used as an inhibitor in extracellular signal-regulated kinase (ERK) inhibition assay in primed induced pluripotent stem cells, RKO colorectal cancer cell line and human embryonic stem cells(hESCs).

Uses

The mitogenic extracellular kinase 1/2 (MEK1/2) inhibitor

Definition

ChEBI: A hydroxamic acid ester that is benzhydroxamic acid (N-hydroxybenzamide) in which the hydroxamic acid group has been converted to the corresponding 2,3-dihydroxypropyl ester and in which the benzene ring has been substituted at position by a (2-fluoro-4-iodophenyl)amino group and at positions 3 and 4 by fluorines (the R enantiomer).

Biochem/physiol Actions

PD 0325901 is a potent MKK1 (MEK1) and MKK2 (MEK2) inhibitor. The Ki is 1.1 and 0.79 nM for MEK1 and MEK2, respectively. PD 0325901 was inactive against a panel of 27 other kinases. PD 0325901 inhibited C26 tumor pERK by 75% when dosed at 25 mg/kg in mice.

storage

-20°C
