Merck, 929301-50MG, FBnG-C3-PEG3-C3-NH2 hydrochloride

Application
Protein degrader building block FBnG-C3-PEG₃-C3-NH₂ hydrochloride enables the synthesis of molecules for degradation of proteins and PROTAC® (proteolysis-targeting chimeras) research. This conjugate contains a p-fluorobenzylguanine (FBnG) ligand, 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.
