Application

Protein degrader building block E7820-PEG1-NH2 hydrochloride enables the synthesis of molecules for targeted protein degradation and PROTAC® (proteolysis-targeting chimeras) research. This conjugate contains a DCAF15-recruiting ligand E7820 (SML2950), a PEG linker, and a pendant amine for reactivity with a carboxylic acid on the target ligand. 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 with a terminal amine, parallel synthesis can be used to more quickly generate degrader libraries that feature variation in crosslinker length, composition, and E3 ligase ligand.
