introduction
1-ethynyl-cyclohexane is an organic intermediate. It has been reported in the literature that it can be used to prepare (E)-2, 2-difluoro-1-phenyl-4-cyclohexenyl-3-en-4-iodo-1-one and 4-phenoxyquinolino N-sulfonamidine compounds.
application example
1-ethynyl-cyclohexane can be used to prepare 4-phenoxyquinolino-N-sulfonamidines having the following structure. These compounds can be used as tyrosine kinase inhibitors, especially c-Met inhibitors. c-Met is highly expressed in most solid tumors and some sarcomas and is closely related to poor prognosis, such as lung cancer, breast cancer, colon cancer, prostate cancer, liver cancer, gastric cancer and glioma. In addition, patients with high HGF/c-Met expression levels have stronger resistance to chemotherapy and radiotherapy. In addition to the abnormal expression of HGF/c-Met, c-Met can also be activated by gene mutation and gene amplification in cancer patients.
