百济神州AR靶向PROTAC专利公开《DEGRADATION OF ANDROGEN RECEPTOR (AR) BY CONJUGATION OF AR ANTAGONISTS WITH E3 LIGASE LIGAND AND METHODS OF USE》

 近日, 百济神州 公开了其双功能 AR PROTAC 降解剂专利公开,该专利( WO2021058017 )最早申请于2019年9月,通过招募E3泛素连接酶来降解AR。 化合物结构通式: 实施例结构摘取部分如下: 根据此前 Arvinas 报道: ARV-110 robustly degrades AR in all cell lines tested, with an observed halfmaximal degradation concentration (DC50) of ~1 nM . “ Proteolysis-targeting chimera (PROTAC) is a novel strategy for selective knockdown of target proteins by small molecules (Sakamoto KM et al., Proc Natl Acad Sci 2001, 98: 8554–9.; Sakamoto K.M. et al., Methods Enzymol. 2005; 399: 833‐847. ) . PROTAC utilizes the Ubiquitin‐protease system to target a specific protein and induce its degradation in the cell (Zhou P. et al., Mol Cell. 2000; 6 (3) : 751‐756; Neklesa T.K. et al., Pharmacol Ther. 2017; 174: 138‐144; Lu M. et al., Eur J Med Chem. 2018; 146: 251‐259; ) . The normal physiological function of the Ubiquitin-protease system is responsible for clearing denatured, mutated, or harmful proteins in cells. The normal physiological function of the Ubiquitin-protease system is responsible
