一种有效的、选择性的、第三代不可逆突变型 EGFR 抑制剂，对 L858R-T790M/L858R/L861Q 的 IC50 分别为 1/12/5 nM。

A potent, selective, third-generation irreversible inhibitor of mutant EGFR with IC50s of 1/12/5 nM for L858R-T790M/L858R/L861Q respectively; weak activity against wt EGFR (IC50=184 nM); inhibits signaling pathways and cellular growth in both EGFRm(+) and EGFRm(+)/T790M(+) mutant cell lines in vitro; exhibits tumor regression in EGFR-mutant tumor xenograft and transgenic models; orally active.Lung Cancer Approved(In Vitro):Osimertinib (AZD9291) (0-10 μM; 72 hours) dramatically inhibits cell proliferation with IC50s of 41, 26, 41, and 31 nM, respectively.Osimertinib (0-10 μM; 72 hours) inhibits cell proliferation (Ba/F3 cells harboring a T790M mutation, exon 19del+T790M, or L858R+T790M) with IC50s of 6, 7, and 74 nM, respectively.Osimertinib (0-10 μM; 72 hours) inhibits Ba/F3 cells harboring EGFR exon 20 insertion mutations (IC50 ranging from 16 to 701 nM for A763_Y764insFQEA (FQEA), Y764_V765insHH (HH), A767_V769dupASV (ASV), and D770_N771insNPG (NPG) cells).Osimertinib shows high levels of phenotype potency in both sensitizing-mutant (mean IC50 of 8 nM in PC-9) and T790M (mean IC50s of 11 and 40 nM in H1975 and PC-9VanR respectively) EGFR cell lines. Osimertinib has much less activity towards wild-type EGFR (mean IC50s of 650 and 461 nM in Calu3 and H2073 respectively).Osimertinib (0.1 μM; 48 hours) induces apoptosis in Ba/F3 cells (apoptosis rates of 40.9% and 90% in EGFR exon 19del+T790M, EGFR L858R+T790M respectively) (In Vivo):Osimertinib (0.1-25 mg/kg; p.o.; daily for 14 days) induces significant dose-dependent regression in both PC-9 (ex19del) and H1975 (L858R/T790M) tumor xenograft models.
