Afatinib dimaleate_product_DataBase

Bioactivity	Afatinib (BIBW 2992) dimaleate 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 dimaleate 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].
Invitro	Afatinib dimaleate (100 nM) sufficiently prevents heregulin-stimulated HER3 phosphorylation[1].Afatinib dimaleate (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 dimaleate (48-72 h)shows growth inhibition in HKESC-1, HKESC-2, SLMT-1 and EC-1 cells[2].Afatinib dimaleate (0-1 μM, 24-48 h) inhibits AKT and MAPK pathways, and inhibits EGFR and AKT phosphorylation in ESCC cell lines[2].Afatinib dimaleate (0-1 μM, 16-48 h) induces G0/G1 cell cycle arrest in HKESC-2 and EC-1[2].Afatinib dimaleate (0-1 μM, 24-48 h) effectively induces apoptotic cell death in HKESC-2 and EC-1[2].
