(+)-Biotin 4-nitrophenyl ester (Biotin-ONp) is a pre-activated biotin derivative, that is used as a biotinylation reagent in the modification of peptides, amino acids and proteins. Biotin-ONp is an effective and efficient tool for the introduction of biotin during solid phase synthesis, offering greater reactivity and higher solubility than Biotin-OSu. It may also be used to prepare biotinylated quinazoline derivatives. Recently, Biotin-ONp has been described as an alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs. PROTACs contain two different ligands connected by a linker, one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
