What is Nonaethylene Glycol Monomethyl Ether ?

Description

m-PEG9-alcohol is a PEG linker containing a hydroxyl group. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The hydrophilic PEG spacer increases solubility in aqueous media.

Definition

ChEBI: Nonaethylene glycol monomethyl ether is nonaethylene glycol in which one of the hydroxy groups is substituted by methoxy. It is functionally related to a nonaethylene glycol.

in vitro

Nonaethylene glycol monomethyl ether is a PEG-based PROTAC linker that can be used to synthesize PROTACs. PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase, and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
