Bifunctional molecules known as PROTACs simultaneously bind an E3 ligase and a protein of interest to direct ubiquitination and clearance of that protein, and they have emerged in the past decade as an exciting new paradigm in drug discovery. In order to investigate the permeability and properties of these large molecules, we synthesized two panels of PROTAC molecules, constructed from a range of protein-target ligands, linkers, and E3 ligase ligands. The androgen receptor, which is a well-studied protein in the PROTAC field was used as a model system. The physicochemical properties and permeability of PROTACs are discussed.

雄激素受体 PROTAC 渗透性的系统研究。

被称为 PROTAC 的双功能分子同时结合 E3 连接酶和感兴趣的蛋白质，以指导该蛋白质的泛素化和清除，并且它们在过去十年中已成为令人兴奋的药物发现新范式。为了研究这些大分子的渗透性和性质，我们合成了两组 PROTAC 分子，这些分子由一系列蛋白质靶标配体、接头和 E3 连接酶配体构成。雄激素受体是 PROTAC 领域中经过充分研究的蛋白质，被用作模型系统。讨论了 PROTACs 的理化性质和渗透性。
