    Nemtabrutinib is an orally available reversible inhibitor of Bruton's tyrosine kinase (BTK; Bruton agammaglobulinemia tyrosine kinase), with potential antineoplastic activity. Upon administration, nemtabrutinib non-covalently binds to and inhibits the activity of both the wild-type and the C481S mutated form of BTK, a resistance mutation in the BTK active site in which cysteine is substituted for serine at residue 481. This prevents the activation of the B-cell antigen receptor (BCR) signaling pathway and BTK-mediated activation of downstream survival pathways. This leads to an inhibition of the growth of malignant B-cells that overexpress BTK. Compared to other BTK inhibitors, nemtabrutinib does not require interaction with the BTK C481 site and inhibits the proliferation of cells harboring the BTK C481S mutation. BTK, a member of the Src-related BTK/Tec family of cytoplasmic tyrosine kinases, is overexpressed or mutated in B-cell malignancies; it plays an important role in the development, activation, signaling, proliferation and survival of B-lymphocytes.
