amino peg9 amine

Amino-PEG9-amine is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.

OICR-8268-acrylic acid-amino-PEG9-amine 是一种 E3 泛素酶配体-连接子偶联物 (E3 Ligase Ligand-linker conjugate)，可用于合成 OICR41114。

OICR41114 (PROTAC4) 是一种针对WDR5的PROTAC降解剂。其能够降解内源性WDR5，EC50为40 nM，Dmax为49%。OICR41114 通过蛋白酶体依赖性机制降解HiBiT标记的WDR5。OICR41114由靶蛋白配体Dimethyl-F-OICR-9429-COOH、E3连接酶配体OICR-8268-acrylic acid和PROTAC linker Amino-PEG9-amine组成。其中，E3连接酶配体与linker形成的偶联物为OICR-8268-acrylic acid-amino-PEG9-amine。
