4-Methyl Erlotinib Hydrochloride Usage And Synthesis

Uses

Erlotinib (E625000) derivative as internal standard for HPLC.

Biological Activity

4-methyl erlotinib is an analog of erlotinib by the addition of a methyl group at the four position of the phenyl group. erlotinib is a tyrosine kinase inhibitor which acts on the epidermal growth factor receptor (egfr) [1].the epidermal growth factor receptor (egfr) autocrine pathway has been important for cancer development and progression, including cell proliferation, apoptosis, angiogenesis, and metastatic spread [2].erlotinib inhibits egfr-associated kinase activity by binding to the egf-activated receptor, with the phenyl group at one end sequestered in a hydrophobic pocket of the kinase domain and the ether linkages at the opposite end projecting into solvent [1].erlotinib can prolong survival in patients with non–small-cell lung cancer after first-line or second-line chemotherapy [3].
