SLU-PP-332 is a pan-estrogen receptor-related receptor (ERR) agonist with high affinity for ERRα, ERRβ, and ERRγ, exhibiting EC50 values of 98, 230, and 430 nM, respectively. SLU-PP-332 enhances mitochondrial function and cellular respiration, increases type IIa oxidized skeletal muscle fibers, and enhances exercise tolerance in skeletal muscle cell lines. It has potential applications in the study of metabolic diseases, improvement of muscle function, and amelioration of metabolic disorders and aging.

ERRα antagonist-1 (ERR+/- antagonist-1) is a high-affinity, selective antagonist of the estrogen-related receptor α (ERRα). It effectively prevents the interaction of ERRα with both Proliferator-activated Receptor γ Coactivator-1α (PGC-1α) and PGC-1β, displaying IC50 values of 170 nM and 180 nM, respectively. Notably, ERRα antagonist-1 does not interfere with the interactions involving ERRβ or ERRγ and the PGC-1α and PGC-1β coactivators. Furthermore, it does not affect the interaction between either ERα or ERβ and PGC-1α or SRC-1.

(rel)-PROTAC ERRα Degrader-1, a relative configuration of PROTAC ERRα Degrader-1, is an estrogen-related receptor alpha (ERRα) degrader comprising an MDM2 ligand binding moiety, a linker, and an ERRα binding moiety [1].
