Background

Pelitinib (also known as EKB-569), a 3-cyanoquinoline, is a potent, and irreversible inhibitor of epidermal growth factor receptor (EGF-R) tyrosine kinase that inhibits the activity of EGF-R with the half maximal inhibition concentration IC50 value of 38.5 nM in vitro [1].

Pelitinib has been found to exert a potent anti-proliferative activity against tumor cells overexpressing EGF-R, including NHEK, A431 and MDA-468 cells, with IC50 values of 61 nM, 125 nM and 260 nM respectively; while it has also been found to potently inhibit EGF-induced phosphorylated EGF-R (pEGF-R) in A431 and NHEK cells with IC50 values ranging from 20 nM to 80 nM [2].
