Discovery of 6-(difluoro(6-(4-fluorophenyl)-[1,2,4]triazolo[4,3- b ][1,2,4]triazin-3-yl)methyl)quinoline as a highly potent and selective c-Met inhibitor
c-Met/HGF overexpression has been detected in many human malignancies including tumors which are resistant to anticancer therapy. Disrupting the aberrant c-Met/HGF axis has enjoyed significant progress in both preclinical and clinical antitumor campaign. To eliminate the OCH2-related metabolic deficiency of our previously reported triazolotriazine 2, we synthesized a series of CH2-/CF2-linked triazolotriazines
