Metaproterenol  (Synonyms: Orciprenaline)

Metaproterenol (Orciprenaline) is a direct-acting sympathomimetic and a β2-adrenergic receptor (β2AR) agonist with an IC₅₀ of 68 nM. Metaproterenol also has anti-inflammatory activity^[1][2].

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^[1].
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^[1].

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^[1].
