KU-596, an investigational new drug that is currently undergoing clinical trials for the treatment of neuropathy and interacts with the Hsp90 C-terminal domain. In particular, we report the design and synthesis of three novel paramagnetic analogs of KU-596, which will be used to obtain long range distances for NMR structural studies of Hsp90 in complex with C-terminal ligands.
配体结合位点的识别代表了基于结构的药物开发计划的起点。缺乏结合位点阻碍了调节目标蛋白质的改进配体的开发。在这封信中,我们描述了允许阐明 Hsp90 C 末端配体结合位点的化学工具的开发。我们的策略基于 KU-596 的顺磁性类似物的制备,KU-596 是一种研究性新药,目前正在进行治疗神经病变的临床试验,并与 Hsp90 C 末端结构域相互作用。特别是,我们报告了 KU-596 的三种新型顺磁性类似物的设计和合成,它们将用于获得长距离的 Hsp90 与 C 末端配体复合的 NMR 结构研究。
