Thalidomide and its analogues are frequently used in PROTAC design. However, they are known to be inherently unstable, undergoing hydrolysis even in commonly utilized cell culture media. We recently reported that phenyl glutarimide (PG)-based PROTACs displayed improved chemical stability and, consequently, improved protein degradation efficacy and cellular potency. Our optimization efforts, aiming
沙利度胺及其类似物经常用于 PROTAC 设计。然而,已知它们本质上不稳定,即使在常用的细胞培养基中也会发生水解。我们最近报道,基于苯基戊二酰亚胺 (PG) 的 PROTAC 显示出更高的化学稳定性,从而提高了蛋白质降解效率和细胞效力。我们的优化工作旨在进一步提高化学稳定性并消除 PG 中容易外消旋的手性中心,从而开发出基于苯基二氢尿嘧啶 (PD) 的 PROTAC。在这里,我们描述了 LCK 导向的 PD-PROTAC 的设计和合成,并将其理化和药理学特性与相应的 IMiD 和 PG 类似物进行比较。
