IC50: 68 nM (β2-adrenergic receptor)

Treatment of Zucker diabetic fatty rats with Metaproterenol for 12 weeks attenuates monocyte activation as well as pro-inflammatory and pro-fibrotic responses in the kidneys and heart. Thus, Metaproterenol might has protective effects against diabetic renal and cardiovascular complications.

Metaproterenol (10 μM; 74 hours; THP-1 cells and bone marrow macrophages) treatment enhances β-arrestin2 and its interaction with IκBα in high glucose-induced THP-1 cells and bone marrow macrophages. Metaproterenol (10 μM; 74 hours; THP-1 cells and bone marrow macrophages) treatment leads to downregulation of NF-κB in high glucose-induced THP-1 cells and bone marrow macrophages. Western Blot Analysis Cell Line: THP-1 cells and bone marrow macrophages Concentration: 10 μM Incubation Time: 74 hours Result: Enhanced β-arrestin2 and its interaction with IκBα. RT-PCR Cell Line: THP-1 cells and bone marrow macrophages Concentration: 10 μM Incubation Time: 74 hours Result: Led to downregulation of NF-κB.
