Application

Protein degrader building block (S,R,S)-AHPC-di-trimethylamide-dioxodisulfide-carbonate ester enables the synthesis of molecules for degradation of proteins and PROTAC® (proteolysis-targeting chimeras) research. This conjugate contains a von Hippel-Lindau (VHL)-recruiting ligand and a pendant disulfide, linked via a carbonate group. The pendant disulfide allows for targeted degradation of antibodies. 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, parallel synthesis can be used to more quickly generate degrader libraries that feature variation in crosslinker length, composition, and E3 ligase ligand.

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
