Leriglitazone (Hydroxypioglitazone) hydrochloride, a metabolite of pioglitazone. Leriglitazone (Hydroxypioglitazone) hydrochloride PioOH is a PPARγ agonist, stabilizes the PPARγ activation function-2 (AF-2) co-activator binding surface and enhances co-activator binding, affording slightly better transcriptional efficacy. Leriglitazone (Hydroxypioglitazone) hydrochloride binds to the PPARγ C-terminal ligand-binding domain (LBD) with a K i of 1.2 μM，Leriglitazone induces transcriptional efficacy of the PPARγ (LBD) with an EC 50 of 680 nM Form:Solid IC50& Target:PPAR-γ
