Application:
N-(3-Chloro-4-Fluorophenyl)-7-Fluoro-6-Nitroquinazolin-4-Amine (CAS: 162012-67-1) is an intermediate in the synthesis of Afatinib Dimaleate (CAS: 850140-73-7). Afatinib Dimaleate is a salt form of Afatinib. Afatinib is a second-generation, orally administered, irreversible inhibitor of the ErbB family of tyrosine kinases. Mechanism of ActionAfatinib downregulates ErbB signalling by covalently binding to the kinase domains of epidermal growth factor receptor (EGFR), human epidermal growth factor receptor (HER) 2 and HER4, resulting in irreversible inhibition of tyrosine kinase autophosphorylation; it also inhibits transphosphorylation of HER3. Afatinib is approved as monotherapy for the treatment of EGFR tyrosine kinase inhibitor (TKI)-naive adults with locally advanced or DefinitionChEBI: A maleate salt obtained by combining afatinib with two molar equivalents of maleic acid. Used for the first-line treatment of patients with metastatic non-small cell lung cancer.
