CC-92480 has a unique and rapid degradation profile: the enhanced efficiency to drive the formation of the protein−protein interaction between Aiolos and cereblon, inducing targeted docking to the CRL4-CRBN E3 ubiquitin ligase complex. The CC-92480-dependent binding of Aiolos/Ikaros to CRBN leads to polyubiquitination and ultimately proteasome-mediated degradation of protein. Rapid and extensive loss of Aiolos/Ikaros in sensitive cells, such as multiple myeloma cells, results in apoptosis and subsequent cell death.
