– PROTAC EGFR degrader 7 (compound 13b) is a potent and selective CRBN-recruiting agent targeting EGFR L858R/T790M mutations with a DC50 of 13.2 nM. It effectively inhibits proliferation in NCI-H1975 cells with an IC50 of 46.82 nM and significantly induces apoptosis and G2/M phase arrest in these cells. Demonstrating antitumor efficacy, PROTAC EGFR degrader 7 holds promise for non-small cell lung cancer (NSCLC) research [1].
