如今,由于癌症的发病机制复杂多样,同时抑制两种或多种途径在癌症治疗中发挥着越来越重要的作用,并且发现细胞周期蛋白依赖性激酶6(CDK6)抑制剂和PIM1抑制剂的组合产生协同作用急性髓性白血病 (AML) 治疗中的作用。因此,我们通过基于药效团和基于结构的虚拟筛选发现了一种靶向CDK6/PIM1的新型lead 1,合成了5个不同系列的新衍生物,获得了一种强效平衡的CDK6/PIM1双重抑制剂51,具有较高的激酶选择性。同时,51显示出出色的安全性和良好的药代动力学特性。此外,51在减轻 AML 负担方面显示出比 palbociclib 和 SMI-4a在体内更强的效力。总之,我们为 AML 治疗提供了一个新方向,并为 AML 临床前研究提供了一个很好的先导化合物。
Phospshoinositide 3-Kinase (PI3K)/Mammalian Target of Rapamycin (mTOR) Dual Inhibitors: Discovery and Structure–Activity Relationships of a Series of Quinoline and Quinoxaline Derivatives
摘要:
The phosphoinositide 3-kinase (PI3K) family catalyzes the ATP-dependent phosphorylation of the 3'-hydroxyl group of phosphatidylinositols and plays an important role in cell growth and survival. There is abundant evidence demonstrating that PI3K signaling is dysregulated in many human cancers, suggesting that therapeutics targeting the PI3K pathway may have utility for the treatment of cancer. Our efforts to identify potent, efficacious, and orally available PI3K/mammalian target of rapamycin (mTOR) dual inhibitors resulted in the discovery of a series of substituted quinolines and quinoxalines derivatives. In this report, we describe the structure-activity relationships, selectivity, and pharmacokinetic data of this series and illustrate the in vivo pharmacodynamic and efficacy data for a representative compound.
