Iberdomide (CC-220) is an orally active and potent cereblon (CRBN) E3 ligase modulator (CELMoD) with an IC₅₀ of ~150 nM for cereblon-binding affinity. Iberdomide, a derivative of Thalidomide (HY-14658), has antitumor and immunostimulatory activities^[1][2].

Iberdomide (CC-220; 0.01, 0.1, 1, 10 μM; 72-96 hrs) has antiproliferative effects in a panel of multiple myeloma (MM) cell lines (EJM, H929, KMS11, KMS128M, KMS12PE, MM1.S, MM1.R, RPM-8226, U266 cells) across a range of concentrations^[1].
Iberdomide (0.1 μM; 96 hrs) induces apoptosis in all MM cell lines^[1].
Iberdomide (0.1 μM; 24, 48, 72 hrs) results in time-dependent increases in G0/G1 and sub-G1 cell cycle fractions on H929 cells^[1].
Iberdomide leads to rapid Aiolos depletion in the KMS12BM line^[1].
Iberdomide (0.1 μM) displays some anti-proliferative activity in two of the Pomalidomide-resistant (PR) lines with cereblon mutations (EJM/PR and H929/PR) along with decreased levels of cereblon protein^[1].
Iberdomide (0.1-1000 nM; 72 hrs) equally induces PBMC-mediated killing of both parental MM1.S cells and MM1.S/PR cells^[1].

Iberdomide (CC-220; 10 mg/kg; oral gavage) after 6 or 24 hours causes higher hCRBN expression in hC343 splenocytes correlated to deeper IKZF1/3 downregulation in WT (C57BL/6), hC123, or-343, (representing two different transgenic founder lines expressing hCRBN) and mCrbn^-/- mice^[2].

Iberdomide is dissolved in DMSO. In the assay, 60 nM 6Xhis-tagged CRBN-DDB1 is combined with 30 nM cy5-conjugated cereblon modulator and 3 nM LanthaScreen Eu-anti-His Tag antibody in 20 mM HEPES pH 7, 150 mM NaCl, 0.005% Tween-20 assay buffer. FRET is observed by exciting at 340 nm and monitoring emission at 615 nm and 665 nm, and FRET efficiency is determined by the ratio of FRET to non-FRET emission. Competing cereblon modulating compound (Iberdomide) or DMSO carrier is titrated and incubated for 10 min before scanning^[1].
