Description: VHN05571, also known as (S,R,S)-AHPC-PEG2-butyl chloride, is a ProTAC building block. This conjugate contains a von Hippel-Lindau (VHL)-recruiting ligand, a linker with both hydrophobic and hydrophilic moieties, and a pendant chloroalkane for reactivity with a nucleophilic group on a target ligand. When used with other protein degrader building blocks with a pendant chloro group, parallel synthesis can be used to more quickly generate ProTAC libraries that feature variation in crosslinker length, composition, and E3 ligase ligand.
