General description

PZ15227 is a proteolysis targeting chimeras (PROTACs) based senolytic agent targeting BCL-XL protein. It is a derivative of ABT-263, a Bcl-2 family protein inhibitor. PZ15227 degrades Bcl-xl by recruiting celebron (CRBN) E3 ligase in senescent cells but not in platelets. Comparative to its parent compound, PZ15227 is less toxic to human platelets because of low CRBN expression in platelets.

In aging mice, osteoclast number increases in cortical bone but declines in trabecular bone, suggesting that different mechanisms underlie age-associated bone loss in these 2 compartments. Osteocytes produce the osteoclastogenic cytokine RANKL, encoded by Tnfsf11. Tnfsf11 mRNA increases in cortical

Small molecules that selectively kill senescent cells (SCs), termed senolytics, have the potential to prevent and treat various age-related diseases and extend healthspan. The use of Bcl-xl inhibitors as senolytics is largely limited by their on-target and dose-limiting platelet toxicity.
