Pomalidomide-linker 1

Background Introduction

Pomalidomide-linker 1 is a synthetic conjugate that integrates the cereblon (CRBN)-binding ligand pomalidomide with a versatile chemical linker. This design enables researchers in the PROTAC (Proteolysis Targeting Chimera) field to develop novel PROTAC molecules for targeted protein degradation. The linker is engineered for facile conjugation to diverse target protein ligands, supporting rapid tailored PROTAC synthesis for chemical biology and drug discovery applications.

Mechanism

Pomalidomide-linker 1 functions as an E3 ligase ligand-linker conjugate. The pomalidomide moiety specifically binds to the cereblon (CRBN) E3 ubiquitin ligase, recruiting it to target proteins tagged by the attached ligand at the linker end. This proximity enables ubiquitination of the target protein by the CRBN E3 ligase complex, culminating in proteasomal degradation. By leveraging the cell's inherent protein degradation machinery, this mechanism allows selective and potent degradation of disease-associated proteins.

Applications

Pomalidomide-linker 1 is widely used in the design and assembly of CRBN-based PROTAC molecules for research and preclinical drug discovery. Researchers employ this conjugate to build custom-targeted protein degraders, facilitating studies in oncology, neurodegenerative diseases, and immunology. It also aids in the validation of new protein targets and streamlines the development of next-generation therapeutics. By enabling the rapid creation of functional PROTACs, Pomalidomide-linker 1 accelerates translational research into targeted protein degradation strategies.
