Iberdomide (CC-220) 是一种新型口服免疫调节化合物，靶向cereblon（cereblon是CRL4CRBN E3泛素连接酶复合体的一部分），IC50为60 nM。Iberdomide (CC-220) 可诱导凋亡并具有抗肿瘤和免疫刺激的活性。 Information Iberdomide (CC-220) is a novel oral immunomodulatory compound that targets cereblon , part of the CRL4CRBN E3 ubiquitin ligase complex, with an IC50 of 60 nM in a competitive TR-FRET assay. Iberdomide (CC-220) induces apoptosis with antitumor and immunostimulatory activities. Targets cereblon 60 nM In vitro In cellular degradation assays, treatment with CC-220 results in the loss of Ikaros protein levels with an EC50 of 1 nM compared to 67 nM for lenalidomide and 24 nM for pomalidomide. CC-220 is similarly potent toward Aiolos, with an EC50 of 0.5 nM compared to 87 nM for lenalidomide and 22 nM for pomalidomide. CC-220 is a potent anti-proliferative and pro-apoptotic compound that shows activity in several MM cell line categories with differing sensitivity to lenalidomide, pomalidomide and dexamethasone. CC-220 induces PBMC-mediated killing of all MM cell lines regardless of the level of Cereblon expression and cell autonomous sensitivity. CC-220 acts through binding of Cereblon, leading to the degradation of the hematopoietic transcription factors Ikaros and Aiolos, followed by disruption of the MM promoting c-Myc/IRF4 axis.
