Lys-PEG3-BA
Lys-PEG3-BA is an EML4-ALK/EGFR PROTAC degrader with DC50 values of 1.32 and 19.66 μM for H3122 (EML4-ALK) and H1975 (EGFR-L858R/T790M) cells, respectively. Lys-PEG3-BA hinders proliferation via rewiring the ubiquitin- proteasome system in vitro. Lys-PEG3-BA can be used for non-small cell lung cancer research.

Lys-PEG3-BA (0-20 μM) leads EML4-ALK decertation in H3122 (EML4-ALK) cells and attains a 91% reduction at 10 μM[2].
Lys-PEG3-BA (0-20 μM) specifically triggers the degradation of EGFR in H1975 (EGFR-L858R/T790M) cells, and attains a 52% reduction at 20 μM [2].
Lys-PEG3-BA (48-72 h) efficiently inhibits H3122 (EML4-ALK) and H1975 cell proliferation with an IC50s of 5.30 μM at 48 h and 18.56 μM at 72 h, respectively[2].

Result:Specifically triggered the degradation of EGFR in H1975 (EGFR-L858R/T790M) cells, without affecting the wild-type EGFR protein level.
Resulted in apparent downregulation of the EML4 ALK protein in H3122 (EML4-ALK) cells at varying doses.
