Selective benzimidazole inhibitors of the antigen receptor-mediated NF-κB activation pathway
摘要:
Dysregulated antigen receptor-mediated NF-kappa B activation can contribute to development of autoimmunity, chronic inflammation, and malignancy. A chemical biology screening strategy has identified a substituted benzimidazole that selectively inhibits antigen receptor-mediated NF-kappa B activation without blocking other NF-kappa B activation pathways. A library of analogs was synthesized and the structure-activity relationship and metabolic stability for the series is presented. (C) 2010 Elsevier Ltd. All rights reserved.
Inhibition of Protein Kinase C-Driven Nuclear Factor-κB Activation: Synthesis, Structure−Activity Relationship, and Pharmacological Profiling of Pathway Specific Benzimidazole Probe Molecules
摘要:
A unique series of biologically active chemical probes that selectively inhibit NF-kappa B activation induced by protein kinase C (PKC) pathway activators have been identified through a cell-based phenotypic reporter gene assay. These 2-aminobenzimidazoles represent initial chemical tools to be used in gaining further understanding on the cellular mechanisms driven by B and T cell antigen receptors. Starting from the founding member of this chemical series 1a (notated in PubChem as CID-2858522), we report the chemical synthesis, SAR studies, and pharmacological profiling of this pathway-selective inhibitor of NF-kappa B activation.
