Submit ReviewErlotinib Hydrochloride
Description: Potent, reversible EGFR tyrosine kinase inhibitor
Chemical Name: N-(3-Ethynylphenyl)-6,7-bis(2-methoxyethoxy)-4-quinazolinamine hydrochloride
Purity: ≥98% (HPLC)
Biological Activity for Erlotinib Hydrochloride
Erlotinib hydrochloride is a reversible, potent EGFR tyrosine kinase inhibitor (IC50 = 2 nM); it reduces EGFR autophosphorylation in intact tumor cells (IC50 = 20 nM). Erlotinib is selective for cell lines showing PC-9 and H3255 mutations (IC50 values are 7 and 12 nM, respectively, sparing wild-type and T790 mutant EGFR. Erlotinib shows antiproliferative effects in cancer cell lines in vitro and promotes differentiation of urothelial organoids. Orally bioavailable.
