Potent and selective BTK Degrader (IC50 = 5.1 nM); degrades BTK in a proteasome- and CRBN-dependent manner. Suppresses BTK signaling and proliferation in mantle cell lymphoma (MCL) cells by degrading BTK, IKFZ1, and IKFZ3 (3 validated targets in B-cell malignancies). Also degrades Ibrutinib (Cat. No. 6813) -resistant C481S-BTK mutant cancer cells. Exhibits no binding against a panel of 468 kinases at 1 μM. Reduces tumor burden and extends survival in lymphoma patient-derived xenograft models.
XMU-MP-3 is a robust, non-covalent inhibitor of BTK, exhibiting exceptional potency with IC50 values of 10.7 nM and 17.0 nM for BTK WT and BTKC481S mutation, respectively, in the presence of 10 μM ATP. Moreover, XMU-MP-3 elicits apoptosis.
