cIAP1 Ligand-LinkerConjugates 3 are chemical compounds comprising an IAP ligand designed specifically for the E3 ubiquitin ligase and a PROTAC linker. These conjugates, denoted as cIAP1 Ligand-LinkerConjugates 3, find utility in the design of SNIPERs, short for Specific and Non-genetic IAP-dependent Protein Erasers [1].
