Beyond the MEK-pocket: can current MEK kinase inhibitors be utilized to synthesize novel type III NCKIs? Does the MEK-pocket exist in kinases other than MEK?

    An approach and preliminary results for utilizing legacy MEK inhibitors as templates for a reiterative structural based design and synthesis of novel, type III NCKIs (non-classical kinase inhibitors) is described. Evidence is provided that the MEK-pocket or pockets closely related to it may exist in kinases other than MEK.
