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.
