  Discovery of azabenzimidazole derivatives as potent, selective inhibitors of TBK1/IKKε kinases

  摘要：

  The design, synthesis and biological evaluation of a series of azabenzimidazole derivatives as TBK1/IKK epsilon kinase inhibitors are described. Starting from a lead compound 1a, iterative design and SAR exploitation of the scaffold led to analogues with nM enzyme potencies against TBK1/IKK epsilon. These compounds also exhibited excellent cellular activity against TBK1. Further structure-based design to improve selectivity over CDK2 and Aurora B resulted in compounds such as 5b-e. These probe compounds will facilitate study of the complex cancer biology of TBK1 and IKK epsilon. (C) 2012 Elsevier Ltd. All rights reserved.

  The discovery and optimization of a series of 6-aryl-azabenzimidazole inhibitors of TBK1 and IKK-epsilon is described. Various internal azabenzimidazole leads and reported TBK1/IKK-epsilon inhibitors were docked into a TBK1 homology model. The resulting overlays inspired a focused screen of 6-substituted azabenzimidazoles against TBK1/IKK-epsilon. This screen resulted in initial hit compound 3. The TBK1/IKK-epsilon enzyme and cell potency of this compound was further improved using structure guided drug design. Systematic exploration of the C6 aryl group led to compound 19, a potent inhibitor of TBK1 with selectivity against cell cycle kinases CDK2 and Aurora B. Further elaboration and optimization gave compound 25, a single digit nM inhibitor of TBK1. These compounds may serve as in vitro probes to evaluate TBK1/IKK-epsilon as an oncology target.

  A series of 5-azaquinoxaline-2,3-dione derivatives were synthesized and evaluated on d-amino acid oxidase (DAAO) inhibition as potential α-hydroxylactam-based inhibitors. The potent inhibitory activities in vitro suggested that 5-nitrogen could significantly enhance the binding affinity by strengthening relevant hydrogen bond interactions.
