ERRα Ligand-LinkerConjugates 1 refers to a chemical compound that consists of a ligand targeting estrogen-related receptor alpha (ERRα), and a PROTAC linker that facilitates the recruitment of E3 ligases MDM2. It finds utility in the synthesis of a range of PROTACs, including one known as PROTAC ERRalpha Degrader-1. With its capability to induce degradation of ERRα, PROTAC ERRalpha Degrader-1 functions as an ERRα degrader[1].
