Description

Biochem/physiol Actions

Potent ABL and SRC family tyrosine kinases (TYKs) degrader with greater antileukemic efficacy than dasatinib in cultures and in vivo.



SJ11646 is a potent and high-affinity (LCK/ABL1/SRC Kd = 0.14/0.054/0.17 nM for SJ11646 vs. 0.09/0.054/0.19 nM for dasatinib) ABL and SRC family tyrosine kinases (TYKs) degrader composed of dasatinib linked to a E3 ligase cereblon (CRBN)-binding ligand. SJ11646 effectively degrades SRC family TYKs in KOPT-K1 cells (LCK, CSK, SRC, FYN; 100 nM for 24h) and is 55,114-times more cytotoxic (LC50 = 0.0123 pM) than dasatinib against the BCR-ABL fusion-harboring B-ALL cell line SUP-B15. When used at equal molar amount via daily i.p., SJ11646 (15 mg/kg) shows significantly greater antileukemic efficacy than dasatinib (10 mg/kg) in two T-ALL PDX models in mice in vivo.
