PROTAC EGFR degrader 18
PROTAC EGFR degrader 18 is a VHL-based PROTAC degrader targeting EGFR. PROTAC EGFR degrader 18 inhibits tumor cell proliferation and induces apoptosis. When functionalized with hyaluronic acid, PROTAC EGFR degrader 18 achieves specific enrichment at tumor sites via CD44-mediated targeting, exerting anti-tumor activity while significantly reducing systemic toxicity. PROTAC EGFR degrader 18 can be used for the research of non-small cell lung cancer.

PRO NP (50-1000 nM; 2-24 h) induces concentration- and time-dependent degradation of EGFR in HCC827 cells[1].
PRO NP (500-1000 nM; 24 h) mediated EGFR degradation in HCC827 cells occurs via the proteasome pathway and requires formation of a ternary complex with EGFR and VHL E3 ubiquitin ligase[1].
PRO NP (1 nM-10 μM; 72 h) inhibits proliferation of HCC827 cells with an IC50 of 314 nM and PC-9 cells with an IC50 of 2.15 μM after 72 h of treatment[1].
PRO NP + HA (1 nM-10 μM; 72 h) inhibits proliferation of HCC827 cells with an IC50 of 164 nM and PC-9 cells with an IC50 of 620 nM after 72 h of treatment, showing enhanced cytotoxicity compared to unmodified PRO NP[1].
PRO NP + HA (1 μM; 48 h) induces apoptosis in 40% of HCC827 cells after 48 h of treatment, showing enhanced pro-apoptotic activity compared to unmodified PRO NP[1].

Cell Line:HCC827 cells
-
Concentration:50-1000 nM (24 h incubation); 500 nM (time-course incubation)
-
Incubation Time:24 h (concentration-dependent); 2-24 h (time-dependent)
-
Result:Induced concentration-dependent EGFR degradation: at 300 nM, EGFR expression was significantly reduced, with maximal degradation at 500 and 1000 nM.
Exhibited time-dependent degradation, with increasing EGFR reduction from 2 to 24 h, and highest efficiency between 4-12 h.

Cell Line:HCC827 cells
-
Concentration:500-1000 nM PRO NP; 400 nM MG132; 10 μM gefitinib, 10 μM VHL ligand, 1 μM PRO NP
-
Incubation Time:24 h (PRO NP/MG132 treatment); 4 h (preincubation), 24 h (PRO NP treatment)
-
Result:MG132 significantly attenuated EGFR degradation induced by 500 nM and 1000 nM PRO NP.
Both gefitinib and VHL ligand markedly reduced PRO NP-mediated EGFR degradation.
