1-(2-(2-(2-aminoethoxy)ethoxy)ethyl)-1H-pyrrole-2,5-dione Chemical Properties, Uses, Production

Uses

Mal-PEG2-NH2 (TFA) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].

Biological Activity

Mal-PEG2-NH2 (TFA) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. 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[1].
