ERRα antagonist-1
ERR+ - antagonist-1, ERRa antagonist-1
T112301072145-33-5In house
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.

SNIPER(ER)-87
T186972222354-91-6
SNIPER(ER)-87 is a chemical compound composed of a derivative of the inhibitor of apoptosis protein (IAP) ligand LCL161 conjugated to the estrogen receptor α (ERα) ligand 4-hydroxytamoxifen using a PEG linker. It effectively degrades the ERα protein with an IC50 value of 0.097 μM. Within cells, SNIPER(ER)-87 selectively recruits XIAP to ERα, and XIAP functions as the primary E3 ubiquitin ligase responsible for the degradation of ERα induced by SNIPER(ER)-87[1][2].

17β-hydroxy Exemestane
T35676122370-91-6
17β-hydroxy Exemestane is the primary active metabolite of exemestane . It is formed by metabolism of exemestane by the cytochrome P450 (CYP) isoforms CYP1A and CYP4A11. 17β-hydroxy Exemestane is an aromatase inhibitor (IC50 = 69 nM using human placental microsomes) and an androgen receptor (AR) agonist (IC50 = 39.6 nM) that is selective for AR over estrogen receptor α (ERα; IC50 = 21.2 μM). It stimulates growth of AR- and ERα-positive MCF-7 (EC50 = 2.7 μM) and T47D breast cancer cells (EC50s = 0.43 and 1,500 nM for AR- and ER-mediated growth, respectively) and inhibits proliferation of testosterone-treated aromatase-overexpressing MCF-7aro cells in a concentration-dependent manner. 17β-hydroxy Exemestane (20 mg/kg) inhibits increases in serum cholesterol and LDL levels and prevents decreases in bone mineral density in the lumbar vertebrae and femur, as well as femoral bending strength and compressive strength of the fifth lumbar vertebrae, in ovariectomized rats.
