Application:
(S)-N-(3-Chloro-4-Fluorophenyl)-6-Nitro-7-((Tetrahydrofuran-3-yl)oxy)quinazolin-4-Amine (CAS: 314771-88-5) is used in the preparation of Afatinib Dimaleate (CAS: 850140-73-7). Afatinib is an innovative anti-cancer target drug, a new generation of oral target drug, the world's first anti-cancer target drug that irreversibly binds to the ErbB family, and is more effective and targeted Blocks the signal that triggers the growth of cancer cells, reducing or delaying the proliferation of cancer cells. Afatinib belongs to a class of drugs known as tyrosine kinase inhibitors. It works by blocking the function of two closely related proteins, the epidermal growth factor receptor (EGFR) and the human epidermal growth factor receptor 2 (HER2). Used for the first-line treatment of patients with metastatic non-small cell lung cancer. Afatinib is an innovative anti-cancer target drug, a new generation of oral target drug, the world's first anti-cancer target drug that irreversibly binds to the ErbB family, and is more effective and targeted Blocks the signal that triggers the growth of cancer cells, reducing or delaying the proliferation of cancer cells.
