Design and synthesis of triazolopyridazines substituted with methylisoquinolinone as selective c-Met kinase inhibitors

A series of triazolopyridazines substituted with methylisoquinolinone were designed and synthesized. Some of the triazolopyridazines strongly inhibited c-Met kinase and showed good anti-proliferative activity against a panel of c-Met-amplified gastric cancer cell lines (MKN-45, SNU-5 and Hs746T).
