Application

Protein degrader building block Pomalidomide-C5-phosphoramidite enables the synthesis of molecules for targeted protein degradation and PROTAC® (proteolysis-targeting chimeras) research. This conjugate contains a Cereblon (CRBN) recruiting ligand, a rigid linker, and a pendant phosphoramidite for reactivity with target DNA-binding proteins such as transcription factors. Because even slight alterations in ligands and crosslinkers can affect ternary complex formation between the target, E3 ligase, and degrader, many analogs are prepared to screen for optimal target degradation. When used with other protein degrader building blocks, parallel synthesis can be used to more quickly generate degrader libraries that feature variation in crosslinker length, composition, and E3 ligase ligand.

DNA-binding proteins, including transcription factors (TFs), play essential roles in various cellular processes and pathogenesis of diseases, deeming to be potential therapeutic targets. However, these proteins are generally considered undruggable as they lack an enzymatic catalytic site or a ligand-binding

Protein homeostasis networks are highly regulated systems responsible for maintaining the health and productivity of cells. Whereas therapeutics have been developed to disrupt protein homeostasis, more recently identified techniques have been used to repurpose homeostatic networks to effect degradation of

Conventional genetic approaches have provided a powerful tool in the study of proteins. However, these techniques often preclude selective manipulation of temporal and spatial protein functions, which is crucial for the investigation of dynamic cellular processes. To overcome these limitations

The current inhibitor-based approach to therapeutics has inherent limitations owing to its occupancy-based model: 1) there is a need to maintain high systemic exposure to ensure sufficient in vivo inhibition, 2) high in vivo concentrations bring potential for off-target side effects, and 3) there is
