EKB-569 (Pelitinib), an irreversible EGFR tyrosine kinase inhibitor has shown potential therapeutic efficiency in solid tumors. In SCC-4 and SCC-9 cells, Pelitinib inhibited IR-induced NF-kB, telomerase activity and hTERT transactivation. Ionizing radiation-induced telomerase activity is regulated at the transcriptional level by triggering TERT promoter activation. Pelitinib potently inhibits the proliferation of normal human keratinocytes (NHEK), as well as A431 and MDA-468 tumor cells with IC50 of 61 nM, 125 nM, and 260 nM. The ABCG2 multidrug transporter confers resistance to gefitinib and pelitinib. In breast and ovarian cancer cells, although ErbB phosphorylation was reduced by pelitinib and canertinib, activation of the AKT/mTOR pathway remained essentially unaltered in drug-resistant cells.
