Biological Activity

Description

DT2216 is a potent and selective degrader of BCL-XL based on PROTAC technology. DT2216 inhibits various BCL-XL-dependent leukemia and cancer cells but considerably less toxic to platelets.

Targets

BCL-XL ^[1]

In vitro

DT2216 is a BCL-XL proteolysis targeting chimera (PROTAC) that targets BCL-XL to the Von Hippel-Lindau (VHL) E3 ligase for degradation. DT2216 is more potent against various BCL-XL-dependent leukemia and cancer cells but significantly less toxic to platelets than ABT263 in vitro because VHL is poorly expressed in platelets.^[1]

In vivo

In vivo, DT2216 effectively inhibits the growth of several xenograft tumors as a single agent or in combination with other chemotherapeutic agents, without causing significant thrombocytopenia.^[1]
