(S,R,S)-AHPC-Me-C10-NH2 hydrochloride is a synthesized E3 ligase ligand-linker conjugate incorporating a VHL ligand and a linker.

(S,R,S)-AHPC-Me hydrochloride (VHL ligand 2 hydrochloride) is a chemical compound utilized in the synthesis of ARV-771, an exceptionally potent BET protein degrader. This compound selectively degrades BET protein in cells resistant to castration, exhibiting a remarkable DC50 <1 nM. Recognized as VHL ligand 2 hydrochloride, (S,R,S)-AHPC-Me hydrochloride serves as the VHL ligand derived from (S,R,S)-AHPC for the recruitment of von Hippel-Lindau (VHL) protein.

(S,R,S)-AHPC-C4-NH2 hydrochloride (E3 ligase Ligand-Linker Conjugates 28) is a synthesized E3 ligase ligand-linker conjugate incorporating the (S,R,S)-AHPC based VHL ligand and a linker.

(S, R, S)-AHPC-PEG4-NH2 hydrochloride is a chemically synthesized conjugate consisting of an E3 ligase ligand-linker, incorporating the VHL ligand based on (S, R, S)-AHPC, and a 4-unit PEG linker, which are specifically designed for use in PROTAC technology.

'(S,R,S)-AHPC-C8-NH2 (VH032-C8-NH2) hydrochloride is a synthetic E3 ligase ligand-linker conjugate, consisting of the VH032-based VHL ligand and a linker for use in PROTAC technology.'

(S,R,S)-AHPC-PEG3-NH2 hydrochloride (E3 ligase Ligand-Linker Conjugates 5) is an E3 ligase ligand-linker conjugate incorporating the (S,R,S)-AHPC-based VHL ligand and 3-unit PEG linker.

(S, R, S)-AHPC-C6-NH2 hydrochloride (also known as VH032-C6-NH2 hydrochloride) is a synthetic E3 ligase ligand-linker conjugate. It combines the VH032-based VHL ligand with a linker designed for AKT PROTAC degrader applications.

(S,R,S)-AHPC-PEG2-NH2 hydrochloride (E3 ligase Ligand-Linker Conjugates 6) is a synthesized E3 ligase ligand-linker conjugate. (S,R,S)-AHPC-PEG2-NH2 hydrochloride incorporates the (S,R,S)-AHPC based VHL ligand and 2-unit PEG linker used in the synthesis of PROTAC.

(S,R,S)-AHPC hydrochloride (Protein degrader 1 hydrochloride) is a building block in the synthesis of proteolysis-targeting chimera technologies (PROTACs).

(S,S,S)-AHPC hydrochloride is a von Hippel-Lindau (VHL) aminoblock. (S,S,S)-AHPC (Compound 27) is often used as a negative control for (S,R,S)-AHPC. (S,R,S)-AHPC is a VHL ligand based on VH032 and can be used to recruit VHL proteins.
