Erlotinib, Free Base, is the free base form of erlotinib hydrochloride (sc-202154), a small molecule EGFR/HER-1 (human epidermal growth factor receptor) tyrosine kinase reversible inhibitor.A tyrosine kinase inhibitor
Information
In vitro
Erlotinib HCl potently inhibits EGFR activation in intact cells including HNS human head and neck tumor cells (IC50 20nM), DiFi human colon cancer cells and MDA MB-468 human breast cancer cells. Erlotinib HCl (1 μM) induces apoptosis in DiFi human colon cancer cells. Erlotinib inhibits growth of a panel of NSCLC cell lines including A549, H322, H3255, H358 H661, H1650, H1975, H1299, H596 with IC50 ranging from 29 nM to >20 μM. Erlotinib HCl(2 μM) significantly inhibits growth of AsPC-1 and BxPC-3 pancreatic cells. The effects of Erlotinib HCl in combination with gemcitabine are considered additive in KRAS-mutated pancreatic cancer cells. Ten micromolar of Erlotinib HCl inhibits EGFR phospho-rylation at the Y845 (Src-dependent phosphorylation) and Y1068 (auto-phosphorylation) sites. Combination with Erlotinib HCl could down-modulate rapamycin-stimulated Akt activity and produces a synergistic effect on cell growth inhibition.
In vivo
At doses of 100 mg/kg, Erlotinib HCl completely prevents EGF-induced autophosphorylation of EGFR in human HN5 tumors growing as xenografts in athymic mice and of the hepatic EGFR of the treated mice. Erlotinib HCl (100 mg/Kg) inhibits H460a and A549 tumor models with 71 and 93% inhibition rate.
