Application

Protein degrader building block A1V2PF1-NHEt-PEG1-NH2 enables the synthesis of molecules for targeted protein degradation and SNIPER (specific and non-genetic inhibitor of apoptosis protein (IAP)-dependent protein erasers) technology. Developed in partnership with ComInnex, this conjugate contains an in silico-derived IAP-recruiting ligand, an alkyl-chain crosslinker, and a pendant amine for reactivity with an acid on a target warhead. Because even slight alterations in ligands and crosslinkers can affect ternary complex formation between the target, E3 ligase, and protein degrader, many analogs are prepared to screen for optimal target degradation. When used with other protein degrader building blocks with a terminal amine, including CRBN and VHL targeted, parallel synthesis can be used to more quickly generate SNIPER and PROTAC® degrader libraries that feature variation in crosslinker length, composition, and E3 ligase ligand.
