Definitions

  • the present invention relates to organic compounds useful for therapy and/or prophylaxis in a patient, and in particular to inhibitors of ITK kinase useful for treating diseases mediated by ITK kinase.
  • Interleukin-2-inducible T-cell kinase is a Tec family kinase that is expressed in T cells, NKT cells, NK cells, and mast cells. ITK is activated downstream of antigen engagement of the T cell receptor (TCR) and mediates TCR signals through the phosphorylation and activation of PLCy. Mice in which ITK is deleted showed defective differentiation of T cells towards the Th2 subset, but not the Thl subset. Additional studies indicate that Th2 cytokine production, but not early Th2 lineage commitment, is defective in ITK-deficient mouse T cells. Th2 cells promote allergic inflammation, and ITK knock-out mice have reduced lung inflammation, mucus production, and airway hyperreactivity in models of allergic asthma.
  • ITK kinase There exists a need for inhibitors of ITK kinase and treatments of diseases and disorders mediated by ITK kinase.
