Two classes of piperazinone-containing thieno[3,2-d]pyrimidines were designed and synthesized as new PI3Kδ inhibitors in this study. Detailed SAR study with respect to the piperazinone substituents at the 6-position of thieno[3,2-d]pyrimidine core demonstrated that piperazinone-containing thieno[3,2-d]pyrimidines would be more potent and selective for PI3Kδ than their piperazine counterparts, which led to the discovery of several potent PI3Kδ inhibitors with comparable or better antiproliferative activity against a panel of non-Hodgkin lymphoma (NHL) cell lines as compared with idelalisib. Our study will promote the development of new PI3Kδ inhibitors based on piperazinone-containing thieno[3,2-d]pyrimidine scaffold.
本研究设计并合成了两类含哌嗪酮的噻吩并[3,2-d]嘧啶类化合物作为新型 PI3Kδ 抑制剂。对噻吩并[3,2-d]嘧啶核心 6 位哌嗪酮取代基的详细 SAR 研究表明，与哌嗪类化合物相比，含哌嗪酮的噻吩并[3,2-d]嘧啶类化合物对 PI3Kδ 的活性更高、选择性更强，由此发现了几种具有较强活性的 PI3Kδ 抑制剂，与idelalisib 相比，对一系列非霍奇金淋巴瘤（NHL）细胞系的增殖活性相当或更好。我们的研究将促进以含哌嗪酮的噻吩并[3,2-d]嘧啶为骨架的新型 PI3Kδ 抑制剂的开发。
