By hijacking endogenous E3 ligase to degrade protein targets via the ubiquitin-proteasome system, PROTACs (PRoteolysis TArgeting Chimeras) provide a new strategy to inhibit protein targets that were previously regarded as undruggable. The compounds described herein comprise a photolabile group on PROTACs, enabling the degradation of protein targets in a spatiotemporally controlled manner. By adding a photolabile caging group on ubiquitin recruiting moieties, light-inducible protein degradation was acheived. These opto-PROTACs display no activity in the dark, while restricted degradation can be induced at a specific time and rate by UVA-irradiation. Accordingly, these compounds provide light-controlled PROTACs and methods of using such compounds.
通过劫持内源性E3连接酶,通过泛素-蛋白酶体系统降解蛋白靶标,PROTACs(蛋白质降解靶向嵌合物)提供了一种新的策略,以抑制先前被认为无法治疗的蛋白靶标。本文所述的化合物包括在PROTACs上的光敏基团,以使蛋白靶标以时空控制的方式降解。通过在泛素招募基团上添加光敏囚禁基团,实现了光诱导的蛋白质降解。这些光控PROTACs在暗处没有活性,而可以通过紫外线照射在特定时间和速率下诱导限制性降解。因此,这些化合物提供了光控制的PROTACs和使用这些化合物的方法。
