piperazines with excellent baseline affinity and selectivity for phosphoinositide 3-kinase δ (PI3Kδ) over closely related isoforms. Rapid evaluation and optimization of structure-activity relationships (SAR) for this class, leveraging the modular nature of this scaffold, facilitated development of this hit class into a series of potent and selective inhibitors of PI3Kδ. This effort culminated in the identification
高通量筛选(HTS)活动鉴定出一类杂芳基哌嗪,它们对紧密相关的同工型具有优异的基线亲和力和对磷酸肌醇3激酶δ(PI3Kδ)的选择性。利用该支架的模块性质,对该类的结构-活性关系(SAR)进行快速评估和优化,有助于将该命中类开发为一系列有效的PI3Kδ抑制剂。这项工作最终确定了29种,在酶和基于细胞的测定中显示了出色的功效,以及良好的药代动力学和脱靶谱。
