Abstract

The discovery of a highly potent and selective small molecule inhibitor 9 for in vitro target validation of MNK1/2 Kinases is described. The aminopyrazine benzimidazole series was derived from an HTS hit and optimized by utilization of a docking model, conformation analysis, and binding pocket comparison against antitargets.
