6,7-Bis(2-Methoxyethoxy)-3H-Quinazolin-4-one (CAS: 179688-29-0) is an intermediate of Erlotinib Hydrochloride (CAS: 183319-69-9). Erlotinib Hydrochlorate is a small molecule tyrosine kinase inhibitor which acts reversibly on epidermal growth factor receptors, a hydrochloride of erlotinib, a molecular-targeted drug. The US Food and Drug Administration (FDA) has approved erlotinib (Tarceva) combined with gemcitabine as a first-line treatment for locally advanced and metastatic pancreatic cancer. It is mainly used as a second- or third-line treatment for locally advanced or metstatic non-small cell lung cancer (NSCLC) and as a treatment for pancreatic cancer. It is used as a tyrosine inhibitor for NSCLC treatment. The small molecular compound Erlotinib Hydrochlorate is a tyrosine kinase receptor inhibitor which inhibits the proliferation of tumor cells by inhibiting phosphorylation, binding to the intracellular catalytic domain of tyrosine kinase in competition with ATP, thus blocking downstream signal transduction and inhibiting activity of tumor cell ligand dependent HER-1/EGFR.
