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 ketone substituted benzimidazole compounds of formula (I) wherein R1, R2, R3, R4 and Xa are defined herein. The compounds of the invention inhibit Itk kinase and are therefore useful for treating diseases and pathological conditions involving inflammation, immunological disorders and allergic disorders. Also disclosed are processes for preparing these compounds and to pharmaceutical compositions comprising these compounds.
