简介内容:HX103, an epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI)-based fluorogenic probe, exhibits selective inhibition towards various EGFR mutations, including EGFR 19 del, EGFR L858R, EGFR wild type, and EGFR T790M, with respective IC50 values of , , , and 977 nM. It is utilized for quantifying active-EGFR to foresee agent sensitivity in NSCLC (non-small cell lung cancer) patients harboring EGFR-activating mutations [1].
