Mitogen/extracellular signal-regulated kinase (MEK) and phosphoinositide 3-kinase (PI3Kα) are considered to be promising targets for the development of anticancer therapeutics. We report the first example of the successful application of structure-based virtual screening to identify novel inhibitors of MEK with IC50 values ranging from 1 to 25 μM. One of the four newly identified MEK inhibitors was found to be also a potent inhibitor of PI3Kα with submicromolar inhibitory activity (IC50 = 0.3 μM). Because this dual inhibitor was screened for having desirable physicochemical properties as a drug candidate as well as the high inhibitory activities against MEK and PI3Kα, it warrants further development through structure–activity relationship (SAR) studies to optimize the inhibitory and anticancer activities. Structural features relevant to the stabilization of the dual inhibitor in the ATP-binding sites of MEK1 and PI3Kα are addressed in detail.
