SJ11646 is a Dasatinib (HY-10181)-based LCK PROTAC degrader with a DC50 of 0.00838 pM. SJ11646 has potent cytotoxicity against LCK-activated T-cell acute lymphoblastic leukemia (T-ALL) cells and primary leukemia samples with drastically prolonged suppression of LCK signaling, and induces T-ALL apoptosis. SJ11646 binds to 51 human kinases with a high affinity (particularly ABL1, KIT, and DDR1). SJ11646 has superior antileukemic efficacy in T-ALL mice model. [1][2]. Pink: LCK ligand (HY-107447), Blue: CRBN ligase ligand (HY-163169), Black: linker (HY-76667)
