Propargyl-PEG6-acid Structural

What is Propargyl-PEG6-acid?

Description

Propargyl-PEG6-acid comprises propargyl and carboxylic acid functional groups. The acid group reacts with primary amines in the presence of activators (e.g. EDC, or HATU).The propargyl group reacts with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The molecule has good solubility in aqueous environment.

The Uses of Propargyl-PEG6-acid

This heterobifunctional, PEGylated crosslinker features a carboxylic acid at one end and propargyl group at the other for reaction with azide-containing compounds using click chemistry. The hydrophillic PEG linker facilitates solubility in biological applications. Propargyl-PEG6-acid can be used for bioconjugation or as a building block for synthesis of small molecules, conjugates of small molecules and/or biomolecules, or other tool compounds for chemical biology and medicinal chemistry that require ligation. Examples of applications include its synthetic incorporation into antibody-drug conjugates or proteolysis-targeting chimeras (PROTAC? molecules) for targeted protein degradation.
