MS154 is a first-in-class E3 ligase cereblon-recruited EGFR degrader with Kd values of 1.8 nM and 3.8 nM for EGFR WT and EGFR L858R mutant, respectively. MS154 potently induces degradation of mutant, but not wild-type, EGFR in cancer cell lines in an E3 ligase-dependent manner. MS154 exhibits anticancer effects against lung cancer (blue: E3 ligase ligand ; black: linker (HY-W096167) ; pink: EGFR ligand (HY-168305) ).
