DY131 (GSK 9089) is a potent and selective ERRγ and ERRβ agonist. DY131displays inactive against ERRα, ERα and ERβ^[1][2]. DY131 also inhibits Smo signaling^[3].

DY131 (0.1-30 μM; 5 days) treatment suppresses cell proliferation and reduces BrdUrd-positive cells in both LNCaP-ERRγ and LNCaP cells in a dose-dependent manner, with higher suppression in LNCaP-ERRγ clone^[1].
DY131inhibits Shh induced accumulation of Smo::EGFP with an IC₅₀ of 0.8 μM. DY131 suppresses SAG (100 nM) induced accumulation of Smo::EGFP in the primary cilium and Gli transcription activity with an IC₅₀ of ~2 μM^[3].
DY131 dramatically decreases phosphorylated histone H3 (pH3) marked proliferation of CGNPs induced by Shh^[3].
A selective ERRγ agonist, DY131, inhibits the growth of the ERα-positive endometrial cancer cells but promoted that of the ERα-negative cancer cells^[4].

DY131 (5 μg/kg; subcutaneous injection; every second day; for 12 days) treatment increases P450 side-chain cleavage (P450scc), StAR and HMGCoA reductase (HMGCR) while decreases hormone sensitive lipase (HSL) expressions^[5].
