5-Formyl-2-Furanboronic Acid (CAS: 27329-70-0) is a boric acid intermediate, widely used in medicine and other fields. Boric acid compounds can react with chlorine, bromine or iodide aromatics and olefins in Suzuki, thereby connecting a variety of groups, and downstream products are very rich.
5-Formyl-2-Furanboronic Acid is an intermediate of Lapatinib (CAS: 231277-92-2) / Lapatinib Ditosylate Monohydrate (CAS: 388082-78-8). Lapatinib (lapatinib), trade name Tykerb, is an oral reversible small molecule tyrosine kinase inhibitor for HER-1/ HER-2. Lapatinib has a different mechanism of action from the approved humanized monoclonal antibody drug Herceptin, which can down-regulate cell proliferation signals by double blocking the HER-1/ HER-2 pathway. Lapatinib in combination with Capecitabine is suitable for the treatment of advanced or metastatic breast cancer patients with HER2(ErbB-2 overexpression) and previous treatment including anthracyclines, paclitaxel and trastuzumab.
