Discovery, SAR and X-ray structure of 1H-benzimidazole-5-carboxylic acid cyclohexyl-methyl-amides as inhibitors of inducible T-cell kinase (Itk)
摘要:
A series of novel potent benzimidazole based inhibitors of interleukin-2 T-cell kinase (Itk) were prepared. In this report, we discuss the structure-activity relationship (SAR), selectivity, and cell-based activity for the series. We also discuss the SAR associated with an X-ray structure of one of the small-molecule inhibitors bound to ITK. (c) 2008 Elsevier Ltd. All rights reserved.
Disclosed are polypeptides encoding the ITK kinase domain and nucleic acids encoding such polypeptides, crystal structures of various polypeptide-ligand complexes comprising the ITK kinase domain bound to a ligand, methods of producing the aforementioned polypeptides and nucleic acids which encode them and methods of producing crystal structures of the aforementioned polypeptides comprising the ITK kinase domain bound to a ligand.
