ASK120067 is a potent and orally active inhibitor of EGFR (IC50:0.3 nM) with selectivity over EGFR (IC50:6.0 nM). ASK120067 is a third-generation EGFR-TKI for the research of non-small cell lung cancer (NSCLC).

体外研究
In the in vitro kinase assay ASK120067 potently inhibits the EGFR L858R/T790M and EGFR T790M resistant mutants with IC50 values of 0.3 nM and 0.5 nM, respectively, as well as the EGFR sensitizing mutant (IC50= 0.5 nM). The 50 of ASK120067 against wild-type EGFR (EGFR) is 6 nM. ASK120067 selectively inhibits the growth of EGFR-mutant cell lines and exhibits potent antiproliferative activity in the mutant EGFR NSCLC cells, with IC50 values of 12 nM, 6 nM and 2 nM against NCI-H1975 (T790M mutation), PC-9, and HCC827 cells (sensitizing mutations), respectively. However, it shows moderate or weak anti-growth activities in A431, LoVo and A549 cells (EGFR), with IC50 values ranging from 338 nM to 1541 nM. ASK120067 (0.1-100 nM) inhibits the phosphorylation of EGFR at Tyrosine residue 1068 and its downstream signaling proteins AKT and ERK in NCI-H1975 cells (EGFR) even at low dosage (0.1-1 nM). Additionally, ASK120067 inhibits p-EGFR and p-Akt and p-erk in EGFR WT A431 cell until the concentration reaches 10 to 100 nM.
体内研究
ASK120067 (oral gavage; 5-20 mg/kg; once daily; 21 days) results in significantly regressed tumor growth, with a tumor growth inhibition (TGI) rate of 85.7%, and administration of 10 mg/kg ASK120067 causes dramatic tumor shrinkage with a TGI rate of 99.3%, exhibiting a similar potency with Osimertinib.
Animal Model:
BALB/cA nude mice
