PI3Kδ inhibitors play an important role in the treatment of leukemia, lymphoma and autoimmune diseases. Herein, using our reported compounds as the lead compound, we designed and synthesized a series of selenium-containing PI3Kδ inhibitors based on quinazoline and pyrido[3,2-d]pyrimidine skeletons. Among them, compound Se15 showed sub-nanomolar inhibition against PI3Kδ and strong δ-selectivity. Moreover
PI3Kδ抑制剂在白血病、淋巴瘤和自身免疫性疾病的治疗中发挥着重要作用。在此,以我们报道的化合物为先导化合物,我们设计并合成了一系列基于喹唑啉和吡啶并[3,2-d]嘧啶骨架的含硒PI3Kδ抑制剂。其中,化合物Se15对PI3Kδ表现出亚纳摩尔级的抑制作用,并且具有很强的δ选择性。此外,Se15对 SU-DHL-6 细胞显示出有效的抗增殖作用,IC 50值为 0.16 μM。分子对接研究表明,Se15能够与PI3Kδ形成多个氢键,并且与PI3Kδ选择性区域紧密堆积。总之,带有吡啶并[3,2- d ]嘧啶支架的含硒化合物Se15是一种新型的有效且选择性的PI3Kδ抑制剂。硒的引入可以丰富PI3Kδ抑制剂的结构,为新型PI3Kδ抑制剂的设计提供新思路。
