  Covalent Inhibitors of Interleukin-2 Inducible T Cell Kinase (Itk) with Nanomolar Potency in a Whole-Blood Assay

  摘要：

  We wish to report a strategy that targets interleukin-2 inducible T cell kinase (Itk) with covalent inhibitors. Thus far, covalent inhibition of Itk has not been disclosed in the literature. Structure-based drug design was utilized to achieve low nanomolar potency of the disclosed series even at high ATP concentrations. Kinetic measurements confirmed an irreversible binding mode with off-rate half-lives exceeding 24 h and moderate on-rates. The analogues are highly potent in a cellular IP1 assay as well as in a human whole-blood (hWB) assay. Despite a half-life of approximately 2 h in resting primary T cells, the covalent inhibition of Itk resulted in functional silencing of the TCR pathway for more than 24 h. This prolonged effect indicates that covalent inhibition is a viable strategy to target the inactivation of Itk.
