Gefitinib-based PROTAC 3 通过 linker 将EGFR结合元件与von Hippel-Lindau配体结合，在 HCC827（外显子 19 del）和 H3255（L858R 突变）细胞中诱导 EGFR 降解，DC50 分别为 11.7 和 22.3 nM。

Gefitinib-based PROTAC 3, conjugating an EGFR binding element to a VHL ligand via a linker, induces EGFR degradation with DC50s of 11.7 nM and 22.3 nM in HCC827(exon 19 del) and H3255 (L858R mutantion) cells, respectively[1].

H3255 cells expressing L858R EGFR treated with Gefitinib-based PROTAC 3 (25 nM-10 μM; 24 hours), HCC827 cells expressing exon 19 del EGFR treated with Gefitinib-based PROTAC 3 (100 nM-10 μM; 24 hours), which enables the degradation of both exon-19 deletion EGFR as well as the mutant isoform containing the L858R activating point mutation, while sparing the WT EGFR[1].
