Propargyl-PEG4-Sulfone-PEG4-t-butyl ester is a PEG linker containing a propargyl group and t-butyl protected carboxyl group acid. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield stable triazole linkages. The t-butyl protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. The protected acid can be deprotected by acidic or basic hydrolysis. The hydrophilic PEG spacer increases solubility in aqueous media. | [Uses]
Propargyl-PEG4-Sulfone-PEG4-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Propargyl-PEG4-Sulfone-PEG4-Boc is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups. | [IC 50]
