Abstact

The identification and hit-to-lead exploration of a novel, potent and selective series of substituted benzimidazole-thiophene carbonitrile inhibitors of IKK-epsilon kinase is described. Compound 12e was identified with an IKK-epsilon enzyme potency of pIC(50) 7.4, and has a highly encouraging wider selectivity profile, including selectivity within the IKK kinase family.
