Hazard Information	Back Directory
[Uses] EMI1 is an EGFR ex19del/T790M/C797S and EGFR L858R/T790M/C797S inhibitor. EMI1 can be used for the research of mutant EGFR-associated, drug-resistant non-small-cell lung cancer (NSCLC)[1].
[Biological Activity] EMI1 (ChemBridge 5213777) is a call penetrant and potent inhibitor of EGFR signaling in EGFR L858R/T790M/C797S and ex19del/T790M/C797S triple mutants associated with drug-resistant NSCLC. AdditionallyEMI1 potently depolymerized interphase microtubulesdisrupts spindle formation and induced mitotic block in PC9 EGFR ex19del/T790M/C797S cells. EMI1 exhibits potent anti-proliferative activity against various cancer cell lines.
