describe the optimization of compound 1, which led to the design and synthesis of pyridyltriazine 31, a potent pan inhibitor of class I PI3Ks with a superior pharmacokinetic profile. Compound 31 was shown to potently block the targeted PI3K pathway in a mouse liver pharmacodynamic model and inhibit tumor growth in a U87 malignant glioma glioblastoma xenograft model. On the basis of its excellent in
磷酸肌醇3-激酶家族催化磷脂酰肌醇-4,5-二磷酸磷酸化为磷脂酰肌醇-3,4,5-三磷酸,其在重要的细胞功能如代谢,细胞生长和细胞存活中起关键作用的次级信使。 。我们努力确定有效,有效和口服可用的磷脂酰肌醇3-激酶(PI3K)抑制剂作为潜在的癌症治疗剂的结果是,发现了4-(2-(((6-methoxypyridin-3-yl)amino)-5-( (4-(甲基磺酰基)哌嗪-1-基)甲基)吡啶-3-基)-6-甲基-1,3,5-三嗪-2-胺(1)。在本文中,我们描述了化合物1的优化,这导致了吡啶基三嗪31的设计和合成,一种具有优异药代动力学特征的有效的I类PI3K泛抑制剂。化合物31在小鼠肝脏药效学模型中显示出有效阻断靶向PI3K途径并在U87恶性神经胶质瘤胶质母细胞瘤异种移植模型中抑制肿瘤生长的作用。基于其出色的体内功效和药代动力学特征,选择化合物31作为临床候选物进行进一步评估,并将其命名为AMG
