Biochem/physiol Actions

LFM-A13 is an inhibitor of the nonreceptor tyrosine kinase Bruton′s tyrosine kinase (Btk), a new molecular target for treatment of B-cell lymphoma and autoimmune disorders. LFMA13 inhibited recombinant BTK with an IC50 value of 2.5microM with 100-fold lower inhibitory activity against a number of other protein kinases including JAK1, JAK2, EGFR, IRK, IKK, and CDK1, 2 and 3, as well as several other related kinases
