A series of thieno[3,2-d]pyrimidine derivatives as phosphatidylinositol 3-kinase (PI3K) inhibitors was designed using the combination strategy. The synthesis and biological evaluation of the derivatives demonstrated their potent inhibition of PI3K, culminating in the discovery of 7 and 21. Determination of a co-crystal structure of 7 complexed with PI3Kα provided the structural basis for the high enzymatic
使用组合策略设计了一系列作为磷脂酰肌醇3-激酶(PI3K)抑制剂的噻吩并[3,2-d]嘧啶衍生物。衍生物的合成和生物学评估表明它们对PI3K具有有效的抑制作用,最终发现了7和21。确定7与PI3Kα络合的共晶体结构为高酶活性提供了结构基础。此外,对化合物7和21的细胞研究表明,它们通过抑制细胞内PI3K / AKT /雷帕霉素途径的哺乳动物靶点而有效抑制了癌细胞系的增殖。结果为PI3K的有效简化抑制剂提供了广阔前景,并提供了用于进一步优化以进行体内实验的化学系列。
