What is NSC 361680?
Description
Bis-PEG1-acid is a PEG linker containing two terminal carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acids can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.
The Uses of NSC 361680
Bis-PEG1-acid is a PEG-based PROTAC linker and can be used in the synthesis of PROTACs as BCL-xL degraders and anticancer agents with low platelet toxicity.
