Description : Icotinib Hydrochloride is a potent and highly selective inhibitor of epidermal growth factor receptor tyrosine kinases (EGFR-TKI) with IC50 value of 5 nM.EGFR is an oncogenic driver which is expressed on the cell surface of normal cells and cancer cells [1], and patients with somatic mutations, particularly an exon 19 deletion or exon 21 L858R mutation, within the tyrosine kinase domain have activating mutations that lead to unchecked cell proliferation.[2] Overexpression of EGFR caused inappropriate activation of the anti-apoptotic Ras signaling pathway, found in many different types of cancer.[3] Icotinib is a quinazoline derivative that binds reversibly to the ATP binding site of the EGFR protein, preventing completion of the signal transduction cascade.[4] Icotinib inhibited the intracellular phosphorylation of tyrosine kinase(TK) associated with the epidermal growth factor receptor (EGFR).[5] Icotinib is indicated for the treatment for EGFR mutation-positive, advanced or metastatic non-small cell lung cancer (NSCLC) as a second-line or third-line treatment, for patients who have failed at least one prior treatment with platinum-based chemotherapy.[6] References:1.A Douglas Laird,and Julie M Cherrington.
