Description

Application

Protein degrader building block C5 Lenalidomide-PEG₁-piperazine 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, a rigid linker, and a pendant amine for reactivity with an acid on the target warhead. 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.
