used moiety to impart selectivity in inhibitors for PI3Kγ and PI3Kδ. Guided by molecular docking, this new specificity piece was then linked to the hinge-binding region of the inhibitor using a novel cyclic moiety. Further structure-activity relationship optimization around the hinge region led to the discovery of candidate 26, a highly potent and selective PI3Kγ-PI3Kδ dual inhibitor with favorable drug
开发了电子密度模型,并用于鉴定喹唑啉酮的新型吡咯烷酮替代物,喹唑啉酮是赋予PI3Kγ和PI3Kδ抑制剂选择性的常用部分。在分子对接的指导下,使用新的环状部分将这一新的特异性片段连接至抑制剂的铰链结合区。围绕铰链区域的进一步的结构-活性关系优化导致了候选化合物26的发现,该候选药物是一种在临床前物种中具有良好药物代谢和药代动力学特性的高效PI3Kγ-PI3Kδ双重抑制剂。
