series of pyrido[2, 3-d]pyrimidin-7(8H)-ones were designed and synthesized as new selective orally bioavailable Threonine Tyrosine Kinase (TTK) inhibitors. One of the representative compounds, 5o, exhibited strong binding affinity with a Kd value of 0.15 nM, but was significantly less potent against a panel of 402 wild-type kinases at 100 nM. The compound also potently inhibited the kinase activity of TTK
一系列吡啶并[2,3- d ]嘧啶-7(8 ħ) -酮,设计并作为新的选择性口服生物可利用苏氨酸酪氨酸激酶(TTK)抑制剂合成。代表性化合物之一5o表现出很强的结合亲和力,K d值为0.15 nM,但在100 nM时对一组402种野生型激酶的效力明显较低。该化合物还有效地抑制TTK的激酶活性,其IC 50 23纳米的值,诱发染色体错误分离和非整倍,并用低μMIC人癌细胞系的面板的抑制增殖50值。化合物5o在大鼠中以25 mg / kg的剂量给药时,具有良好的口服药代动力学特性,生物利用度值为45.3%。此外,5o与紫杉醇的联合治疗在裸鼠中显示出对HCT-116人结肠癌异种移植模型的有希望的体内疗效,其肿瘤生长抑制(TGI)值为78%。抑制剂5o可能为进一步验证TTK抑制的治疗潜力提供一种新的研究工具。
