Gefitinib belongs to a class of tyrosine kinase inhibitors (TKI) designed to compete with ATP for binding into the ATP binding pocket of mutated or over-expressed receptor and thus inhibit its tyrosine kinase activity and the signaling events downstream of it. Gefitinib along with erlotinib have been used to target epidermal growth factor receptor, Egfr. Gefitinib, presented here, was among the first and the most widely used TKI for use in the treatment of locally advanced or metastatic non-smal

Pathwaynon-small cell lung cancer pathwayLung cancer, a major cause of cancer mortality, has been assigned to two types: small-cell (SCLC) and non-small cell lung cancer (NSCLC). The first, an extremely aggressive form of cancer accounts for ~20% of cases while the second accounts for the remaining ~80%.
