We have recently identified BMS-345541 (1) as a highly selective and potent inhibitor of IKK-2 (IC50 = 0.30 mu M), which however was considerably less potent against IKK-1 (IC50 = 4.0 mu M). In order to further explore the SAR around the imidazoquinoxaline tricyclic structure of 1, we prepared a series of tetracyclic analogues (7, 13, and 18). The synthesis and biological activities of these potent IKK inhibitors are described. (c) 2006 Elsevier Ltd. All rights reserved.
