Epertinib (S-22611) hydrochloride is a potent, orally active, reversible, and selective tyrosine kinase inhibitor of EGFR, HER4 and HER2, with IC50s of 1.48 nM, 2.49 nM and 7.15 nM, respectively. Epertinib hydrochloride shows potent antitumor activity[1][2]. Epertinib (hydrochloride) is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
Epertinib hydrochloride inhibits the phosphorylation of EGFR and HER2 in NCI-N87 cells, with IC50 values of 4.5 and 1.6 nM, respectively[2].
Epertinib hydrochloride shows inhibitory activity against MDA-MB-361 cell, with an IC50 of 26.5 nM[1].
Epertinib hydrochloride (0-10 μM, 72 h) can selectively inhibit the proliferation of a range of cancer cell lines expressing EGFR and/or HER2[2].
Epertinib hydrochloride (0-100 mg/kg, Orally, once daily for 28 days) shows antitumor activity[1].
Epertinib hydrochloride (50 mg/kg, Orally, once daily for 30 days) significantly reduces the brain tumor volume[1].
Epertinib hydrochloride (0-50 mg/kg, Orally, once daily for 10-28 days) significantly inhibits the tumor growth in a dose-dependent manner[2].
