Uses:
Fmoc-N-amido-PEG4-acid (Fmoc-NH-PEG4-COOH) is a PEG derivative containing an Fmoc-protected amine and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond.
Fmoc-N-amido-PEG4-acid has various uses, such as 1) used as a cleavable ADC linker for antibody-drug conjugates (ADCs); 2) used as a PEG-based PROTAC linker for the synthesis of PROTACs.
