In 2000, Wyeth reported that the 3-quinolinecarbonitrile ring system was a template for EGFR inhibitors. It soon became apparent that the group at C-4 of this core was responsible for kinase selectivity. A 4-(2,4-dichloro-5- methoxyanilino) substituent provided potent inhibitors of Src, a non-receptor tyrosine kinase that plays a key role in cell signaling. One compound from this series, SKI-606, bosutinib, is currently in clinical trials for the treatment of cancer.
