Description

Biochem/physiol Actions

DT2216 is a selective BCL-XL, but not BCL-2 or BCL-W, degrader composed of a von Hippel-Lindau (VHL) E3 ligase-targeting ligand linked to a ABT-263 (navitoclax) derivative. DT2216 is more potent than ABT-263 against BCL-XL-dependent leukemia (MOLT-4 IC50 = 52 vs 191 nM) and cancer cells (MDA-MB-231 IC50 = 229 vs 707 nM). DT2216 effectively inhibits the growth of several xenograft tumors in vivo either alone (15 mg/kg/wk i.p.) or in combination with other chemotherapeutic agents (docetaxel or VDL), exhbiting improved efficacy and reduced thrombocytopenia when compared with ABT-263 as a result of greatly reduced platelet toxicity due to poor VHL expression in platelets.
