Abstract

Employing phenylmalonitrile dianion chemistry, a large number of analogues of MEK Inhibitor lead SH053 (IC(50)=140 nM) were rapidly synthesized leading to single digit nM inhibitors, displaying submicromolar AP-1 transcription inhibition in COS-7 cells. Compound 41, exhibiting a MEK IC(50)=12 nM showed IP activity in a TPA-induced ear edema model with an ED(50)=5 mg/kg.
