New IKK inhibitors: Synthesis of new imidazo[1,2-a]quinoxaline derivatives using microwave assistance and biological evaluation as IKK inhibitors

The inhibition of the NF-kappa B-dependent pathways by IKK inhibitors plays an important role in immunity, inflammation, and cancer. New imidazoquinoxalines tricyclic derivatives are prepared using microwave assistance and their biological activities as IKK inhibitors are described. Compounds 6a present a potent inhibition activity and selectivity for IKK2. Docking studies in the IKK2 binding site allowed identification of residues most likely to interact with theses inhibitors and explain their potent IKK2 inhibition activity and selectivity.
