MedChemExpress - Model Afatinib - 850140-72-6

Afatinib (BIBW 2992) is an orally active, potent and irreversible dual specificity inhibitor of ErbB family (EGFR and HER2), with IC50 values of 0.5 nM, 0.4 nM, 10 nM and 14 nM for EGFRwt, EGFRL858R, EGFRL858R/T790M and HER2, respectively. Afatinib can be used for the research of esophageal squamous cell carcinoma (ESCC), non-small cell lung cancer (NSCLC) and gastric cancer[1][2][3][4].

Description：Afatinib (BIBW 2992) is an orally active, potent and irreversible dual specificity inhibitor of ErbB family (EGFR and HER2), with IC50 values of 0.5 nM, 0.4 nM, 10 nM and 14 nM for EGFRwt, EGFRL858R, EGFRL858R/T790M and HER2, respectively. Afatinib can be used for the research of esophageal squamous cell carcinoma (ESCC), non-small cell lung cancer (NSCLC) and gastric cancer.

In Vitro：Afatinib (100 nM) sufficiently prevents heregulin-stimulated HER3 phosphorylation[1]. Afatinib (0-10000 nM) effectively inhibits anchorage-independent proliferation of NIH-3T3 cells ectopically expressing EGFR mutants, and inhibits cell proliferation of H1666, H3255, and NCI 1975 cells[1]. Afatinib (48-72 h)shows growth inhibition in HKESC-1, HKESC-2, SLMT-1 and EC-1 cells[2]. Afatinib (0-1 μM, 24-48 h) inhibits AKT and MAPK pathways, and inhibits EGFR and AKT phosphorylation in ESCC cell lines[2]. Afatinib (0-1 μM, 16-48 h) induces G0/G1 cell cycle arrest in HKESC-2 and EC-1[2]. Afatinib (0-1 μM, 24-48 h) effectively induces apoptotic cell death in HKESC-2 and EC-1[2].

In Vivo：Afatinib (0-20 mg/kg, Orally, daily for 25 days) shows dramatic tumor regression and downregulation of EGFR, HER2, HER3 and AKT phosphorylation[1]. Afatinib (15 mg/kg, Orally, in a schedule of 5 days on plus 2 days off, for two weeks) strongly inhibits the growth of HKESC-2 tumor[2].

IC50 & Target：EGFRL858R 0.4 nM (IC50) EGFR 0.5 nM (IC50) EGFRL858R/T790M 10 nM (IC50) HER2 14 nM (IC50) HER3
