Lenalidomide is a TNF-α secretion inhibitor with IC50 of 13 nM in PBMCs. Lenalidomide (CC-5013) is a ligand of ubiquitin E3 ligase cereblon (CRBN), and it causes selective ubiquitination and degradation of two lymphoid transcription factors, IKZF1 and IKZF3, by the CRBN-CRL4 ubiquitin ligase. Lenalidomide promotes cleaved caspase-3 expression and inhibit VEGF expression and induces apoptosis.
