tumors like hepatocellular carcinoma (HCC) is rarely reported. Thus, the development of potent and selective PI3Kδ inhibitors with a new chemotype and therapy is highly desirable. Through the scaffold-hopping strategy, indazole was first described as the core structure of propeller-shaped PI3Kδ inhibitors. A total of 26 indazole derivatives were designed and prepared to identify a novel compound 9x
PI3Kδ 抑制剂已被开发用于治疗 B 细胞恶性肿瘤以及炎症和自身免疫性疾病。然而,它们在肝细胞癌 (HCC) 等实体瘤中的治疗作用却鲜有报道。因此,非常需要开发具有新化学类型和治疗的强效和选择性PI3Kδ抑制剂。通过支架跳跃策略,吲唑首次被描述为螺旋桨形PI3Kδ抑制剂的核心结构。共设计和制备了 26 种吲唑衍生物,用于鉴定具有良好异构体选择性、PK 曲线和效力的新型化合物9x 。与 Idelalisib 和索拉非尼相比,药效学 (PD) 研究表明,9x在 HCC 细胞系和异种移植模型中表现出卓越的功效,并且机制研究表明,9x强烈抑制下游 AKT 途径,从而在 HCC 模型中诱导随后的凋亡细胞死亡。因此,这项工作为 PI3Kδ 抑制剂的新结构设计提供了一种新的有效治疗 HCC 的小分子。
