pathways. However, the functional role of class II PI3Ks is still unclear. Herein, we describe the synthesis of a panel of compounds that were tested against all eight mammalian PI3K-isoforms. We found inhibitors with some selectivity for class II PI3K-C2γ and also compounds with preferred inhibition of class II PI3K-C2β, providing structural leads to develop selective tool compounds.
多年前就意识到完全阐明磷酸肌醇3激酶(PI3K)的生物学功能的重要性。它们产生3-磷酸肌醇,已知其在许多细胞间和细胞内信号传导途径中起重要的第二信使作用。但是,II类PI3K的功能作用仍不清楚。在这里,我们描述了针对所有八个哺乳动物PI3K同工型测试的一组化合物的合成。我们发现了对II类PI3K-C2γ具有一定选择性的抑制剂,以及对II类PI3K-C2β具有较好抑制作用的化合物,为开发选择性工具化合物提供了结构性线索。
