MS39 (11-point 3-fold dilution series up to 30 μM) binds with high affinity to both purified wild-type EGFR (Kd=11 nM) and EGFRL858R mutant (Kd=12 ± 7 nM) proteins in a competitive binding assay[1].
MS39 (1-10000 nM; 16 h) potently induces concentration-dependent degradation of EGFR e19d in HCC-827 cells with a DC50 of 5.0 nM over 16 h, and inhibits downstream EGFR-AKT signaling[1].
MS39 (1-10000 nM; 16 h) potently induces concentration-dependent degradation of EGFRL858R in H3255 cells with a DC50 of 3.3 nM over 16 h, and inhibits downstream EGFR-AKT signaling[1].
