(S,R,S)-AHPC-Me-CO-CH2-PEG3-NH2 is a synthetic E3 ligase ligand-linker conjugate composed of a VHL ligand and a linker, utilized in PROTAC BRD4 Degrader-5 and PROTAC BRD4 Degrader-5-CO-PEG3-N3.

CEP1347-VHL-02 is a PROTAC that selectively targets MLK3. This compound is composed of the target protein ligand CEP-1347, the E3 ubiquitin ligase ligand (S,R,S)-AHPC-Me, and the PROTAC linker Amino-PEG3-CH2COOH. The participating component responsible for controlling the target protein ligand activity is CEP-1347-acid, whereas the conjugate of the E3 ubiquitin ligase ligand and linker is identified as (S,R,S)-AHPC-Me-CO-CH2-PEG3-NH2.
