product name Osimertinib (AZD9291)
Description: Osimertinib (also known as AZD-9291) is an oral available, irreversible, and mutant-selective EGFR inhibitor with IC50 of 12.92, 11.44 and 493.8 nM for Exon 19 deletion EGFR, L858R/T790M EGFR, and WT EGFR in LoVo cells, respectively. It inhibits both activating and resistant EGFR mutations while sparing the normal form of EGFR that is present in normal skin and gut cells, thereby reducing the side effects encountered with currently available medicines.

In vitro activity: AZD9291 shows significantly more potent inhibition of proliferation in mutant EGFR cell lines compared to wild-type in vitro. Kinase Assay: Cell Assay: AZD9291 potently inhibits EGFR phosphorylation in EGFRm+ (e.g. PC9; < 25 nM) and EGFR m+/T790M (e.g. H1975; < 25 nM) cell lines in vitro, whilst demonstrating much less activity against wild-type EGFR lines (e.g. LoVo; > 500 nM). Consistently, AZD9291 showed significantly more potent inhibition of proliferation in mutant EGFR cell lines compared to wild-type in vitro. |
