Background: Erlotinib HCl is a directly acting inhibitor of epidermal growth factor receptor (EGFR/HER-1) tyrosine kinase with an IC50 of 2 nM.

Epidermal growth factor receptor (EGFR) is one member of the ErbB family which includes EGFR (ErbB1), ErbB2, ErbB3 and ErbB4. The activation of EGFR is dependent on the binding of peptide growth factors to the receptor. In many carcinomas, the presence of EGFR mutation leads to the activation of EGFP, which causes cell proliferation and other cancer processes [1].

Selective inhibition of EGFR tyrosine kinase by erlotinib hydrochloride leads to the disruption of cancer growth and development which include cell migration, proliferation, angiogenesis, and apoptosis. For instance, erlotinib hydrochloride was shown to induce cell apoptosis and G0/G1 cell cycle arrest in hepatocellular cancer cells, Bxpc-3 and PANC-1 cells, thereby enhancing chemosensitivity towards cytostatics [2, 3].

In addition, this product is widely researched and used for the treatment of human advanced non-small cell lung cancer (NSCLC) [4]. In pancreatic cancer, erlotinib hydrochloride was also reported to exhibit an anti-tumour effect [5].
