Mechanism of Action

Targets/IC₅₀/Ki	MEK1/2
In vitro	PD318088 is a small-molecule inhibitor of MEK1/2, which is an analog of PD184352, suggesting it might have substantial anti-proliferative activity against cancer cells, although no functional study of this compound is currently available. This inhibitor binds simultaneously with ATP in a region of the MEK1 active site that is adjacent to the ATP-binding site. Formation of the ternary complexes with this chemical and MgATP results in moderate increases (to 140 nM) for the K_d monomer-dimer for both MEK1 and MEK2. The binding of this compound and MgATP to MEK1 also abolishes the formation of tetramers and higher-order aggregates. This compound and MgATP together increase the dimerization disassociation constant for MEK1 and MEK2 slightly from ~75 nM to ~140 nM, suggesting that the mechanism of inhibition for this molecule is probably a result of localized conformational changes in the active site and not a global change in the overall structure.
