In this study, a series of new 6-aryl substituted 4-anilinequinazolines was designed and synthesized as PI3Kδ inhibitors based on our reported chemical structures. The preliminary structure-activity relationship (SAR) was established, and compounds 13h and 13k displayed most potent PI3Kδ inhibitory activities with the IC50 values of 9.3nM and 9.7nM, respectively. Compound 13h demonstrated similar anti-proliferative
在这项研究中,根据我们报道的化学结构,设计并合成了一系列新型的6-芳基取代的4-苯胺喹唑啉类化合物作为PI3Kδ抑制剂。建立了初步的构效关系(SAR),化合物13h和13k显示出最有效的PI3Kδ抑制活性,IC50值分别为9.3nM和9.7nM。化合物13h对三种人类B细胞系表现出了与艾得拉西类似的抗增殖特性。在与PI3Kδ酶的13h对接中发现了三个关键的氢键相互作用。这些结果表明化合物13h具有纳摩尔PI3Kδ抑制活性和独特的化学结构,值得进一步的结构优化。
