Soquelitinib

Chemical Information
Soquelitinib is an orally available, small-molecule, irreversible inhibitor of interleukin-2 inducible T-cell kinase (ITK) with potential immunomodulatory and antineoplastic activities. Upon oral administration, soquelitinib selectively and covalently binds to the cysteine residue at position 442 (CYS-442) of ITK, thereby disrupting ITK-mediated signal transduction, while sparing tyrosine-protein kinase TXK (resting lymphocyte kinase, RLK) activity. This may abrogate T-cell receptor (TCR) signaling through ITK and inhibit TCR-induced proliferation of malignant T-cells. Additionally, inhibiting ITK activation may prevent the upregulation of GATA-3, a transcription factor that drives T-helper 2 (Th2) cell differentiation and is overexpressed in certain T-cell lymphomas. Thus, selective inhibition of ITK may inhibit Th2 responses without affecting T-helper 1 (Th1)-dependent immunity. ITK, a member of the Tec family of non-receptor protein tyrosine kinases plays a significant role in the T-cell development, differentiation and production of pro-inflammatory cytokines.
