Gly-PEG3-BA
Gly-PEG3-BA is an EML4-ALK PROTAC degrader. Gly-PEG3-BA effectively reduces EML4-ALK with a DC50 value of 0.50 μM in H3122 (EML4-ALK) cells. Gly-PEG3-BA effectively reduces EGFR mutant (L858R/T790M) levels with a DC50 of 20.15 μM in H1975 (EGER-L858R/T790M) cells. Gly-PEG3-BA exerts potent antiproliferation activity in H3122 (EML4-ALK) and H1975 (EGER-L858R/T790M) cells with IC50s value of 0.84 and 20.74 μM. Gly-PEG3-BA can be used for non-small lung cancer research.

Gly-PEG3-BA (0-20 μM, 72 h) exhibits highly target-selective activity against EGFR in H1975 cells (harboring the EGFR L858R/ T790M double mutation) and induces dose-dependent targeted degradation of the EML4-ALK fusion protein in H3122 (EML-ALK) cells[1].
Gly-PEG3-BA (0-20 μM, 48 or 72 h) tune down EML4-ALK and EGFR mutant efficiently and confer potent antiproliferation activity in H3122 (EML-ALK) and H1975 (EGER-L858R/T790M) cells with IC50 values of 0.84 and 20.74 μM[1].
Gly-PEG3-BA (0-72 h, 48 or 72 h) effectively decreases EML4-ALK or EGFR mutant protein levels in a dose-dependent manner in H3122 and H1975 cells[1].
Gly-PEG3-BA induces the degradation of EML4-ALK and mutant EGFR, and this degradation process is mediated by ZYG11B and ZER1 in H3122 and H1975 cells (knocked down ZYG11B and ZER1 expression)[1].
