SPDP-PEG8-acid Usage And Synthesis
Description
SPDP-PEG8-acid is a PEG linker containing SPDP crosslinker and carboxylic acid moieties. SPDP is reactive toward thiol groups and contains a cleavable disulfide bond. Its membrane permeability allows for intracellular crosslinking reactions. The terminal caboxylic acid can react with primary amines in the presence of activators such as EDC and HATU to form stable amide bonds. The hydrophilic properties of the PEG linkers increase compound solubility in aqueous media.
Uses
OPSS-PEG8-COOH is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
