N-(Azido-PEG3)-N-Fluorescein-PEG4-acid Chemical Properties,Usage,Production

Uses

N-(Azido-PEG3)-N-Fluorescein-PEG4-acid is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. N-(Azido-PEG3)-N-Fluorescein-PEG4-acid is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

Biological Activity

N-(Azido-PEG3)-N-Fluorescein-PEG4-acid 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].
