Application

Protein degrader builiding block C5 Lenalidomide-PEG3-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 with alternative exit vector and a PEGylated crosslinker with pendant amine for reactivity with an acid on the target warhead. Because even slight alterations in ligands, warheads, 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.

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

Traditional pharmaceutical drug discovery is almost exclusively focused on directly controlling protein activity to cure diseases. Modulators of protein activity, especially inhibitors, are developed and applied at high concentration to achieve maximal effects. Thereby, reduced bioavailability and off-target effects can

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
