Synthesis and Biological Evaluation of 4-Anilinoquinolines as Potent Inhibitors of EpDEermal Growth Factor Receptor

摘要

The mutant receptor tyrosine kinase EGFR is a valDEated and therapeutically amenable target for genotypically selected lung cancer patients. Here we present the synthesis and biological evaluation of a series of 6- and 7-substituted 4-anilinoquinolines as potent type I inhibitors of clinically relevant mutant variants of EGFR. Quinolines 3a and 3e were found to be highly active kinase inhibitors in biochemical assays and were further investigated for their biological effect on EGFR-dependent Ba/F3 cells and non-small cell lung cancer (NSCLC) cell lines.
