ASK120067 is a novel third-generation inhibitor of EGFR T790M (L858R/T790M IC50=0.3 nM, T790M IC50=0.5 nM), with selectivity over EGFR WT (IC50=6 nM).ASK120067 potently inhibited the EGFR L858R/T790M and EGFR T790M resistant mutants, with IC50 of 0.3 nM and 0.5 nM, respectively, as well as the EGFR exon19del sensitizing mutant (IC50= 0.5 nM).ASK120067 also displayed a favorable selectivity profile against a panel of 258 kinases.ASK120067 selectively inhibits the growth of EGFR-mutant cell lines and induces apoptosis, with IC50 values of 12 nM, 6 nM and 2 nM against NCI-H1975, PC-9, and HCC827 cells, respectively.ASK120067 dose-dependently inhibited EGF-induced EGFR L858R/T790M phosphorylation and consequent activation of the downstream molecules AKT and ERK in NCI-H1975 cells, with similar or even more effective potency than osimertinib.ASK120067 (5, 10 mg/kg once daily) demonstrated profound and selective antitumor efficacy in EGFR-mutant xenograft models in vivo.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
