Application

Protein degrader building block Pomalidomide-C3-NH2 hydrochloride enables the synthesis of molecules for targeted protein degradation and PROTAC (proteolysis-targeting chimeras) technology. This conjugate contains a Cereblon (CRBN)-recruiting ligand and an alkyl-chain crosslinker with pendant amine for reactivity with an acid on the target ligand. Because even slight alterations in ligands and crosslinkers can affect ternary complex formation between the target, E3 ligase, and PROTAC, many analogs are prepared to screen for optimal target degradation. When used with other protein degrader building blocks with a terminal amine, parallel synthesis can be used to more quickly generate PROTAC libraries that feature variation in crosslinker length, composition, and E3 ligase ligand.

An organic base-promoted chemoselective alkylation of lenalidomide with different halides was developed, which offers a novel approach to a highly functionalized lenalidomide-based PROTAC library under mild reaction conditions. DIPEA was found to act as an efficient base to trigger facile

Human murine double minute 2 (MDM2) protein is a primary endogenous cellular inhibitor of the tumor suppressor p53 and has been pursued as an attractive cancer therapeutic target. Several potent, nonpeptide, small-molecule inhibitors of MDM2 are currently in clinical development.

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
