| Abstract | Interleukin-2 inducible T-cell kinase (ITK), a member of the Tec family of tyrosine kinases, plays an important role in T cell signaling downstream of the T-cell receptor (TCR). Herein we report the discovery of a series of indolylindazole based covalent ITK inhibitors with nanomolar inhibitory potency against ITK, good kinase selectivity and potent inhibition of the phosphorylation of PLC gamma l and ERK1/2 in living cells. A computational study provided insight into the interactions between inhibitors and Phe437 at the ATP binding pocket of ITK, suggesting that both edge-to-face pi-pi interaction and the dihedral torsion angle contribute to inhibitors' potency. Compounds 43 and 55 stood out as selective covalent inhibitors with potent cellular activity, which could be used as chemical tools for further study of ITK functions. (C) 2019 Elsevier Masson SAS.
