(2S,4R)-N-[(1S)-1-(4-fluorophenyl)-3-(methylamino)-3-oxopropyl]-4-hydroxy-1-[(2R)-3-methyl-2-(3-methyl-1,2-oxazol-5-yl)butanoyl]pyrrolidine-2-carboxamide

Background Introduction

(2S,4R)-N-[(1S)-1-(4-fluorophenyl)-3-(methylamino)-3-oxopropyl]-4-hydroxy-1-[(2R)-3-methyl-2-(3-methyl-1,2-oxazol-5-yl)butanoyl]pyrrolidine-2-carboxamide is a highly specialized ligand designed to engage the E3 ubiquitin ligase VHL (von Hippel-Lindau). VHL-based ligands are integral tools in targeted protein degradation (TPD) strategies, particularly in the synthesis of PROTACs (Proteolysis Targeting Chimeras), where they enable precise recruitment of the VHL E3 ligase complex.

Mechanism

This compound specifically binds to the VHL E3 ligase, facilitating the recruitment of the VCB (VHL-Cullin 2-Elongin B/C) ligase complex to the target protein. When incorporated as the E3 ligase ligand portion of a PROTAC, it creates a proximity-induced interaction between the target protein and the E3 ligase machinery. This drives polyubiquitination of the target protein, marking it for rapid recognition and degradation via the 26S proteasome. The presence of tailored chemical groups such as the 4-fluorophenyl and 3-methyl-1,2-oxazol moieties optimizes ligand affinity, selectivity, and solubility for efficient PROTAC design.

Applications

This VHL ligand is a valuable scaffold for creating bifunctional molecules used in PROTAC-based research and drug discovery. Applications include:

• Synthesis of VHL-recruiting PROTACs for targeted protein degradation
