  摘要：

  在许多人类恶性肿瘤（包括对抗癌治疗有抵抗力的肿瘤）中已经检测到c-Met / HGF的过度表达。在临床前和临床抗肿瘤运动中，破坏异常的c-Met / HGF轴都取得了重大进展。为了消除OCH 2我们以前报道triazolotriazine的-相关代谢不足2，合成了一系列的CH 2 - / CF 2 -连接triazolotriazines并评估他们的c-Met活动，导致高度有效的化合物23与IC 50c-Met中0.24 nM的酶活性和EBC-1癌细胞系中0.85 nM的细胞活性值以及EBC-1异种移植小鼠模型在口服剂量为25 mg / kg时肿瘤完全消退。基于其强大的抗增殖活性和良好的药代动力学特性，已选择23种药物作为临床前研究的候选药物。
