Metaproterenol hemisulfate salt (CAS 5874-97-5)

Metaproterenol hemisulfate salt is a synthetic sympathomimetic amine that acts as a beta-adrenergic agonist, specifically binding to the beta-2 adrenergic receptor (ADRB2). Its mechanism of action involves activating the G-protein coupled receptor, stimulating the production of cyclic adenosine monophosphate (cAMP), and subsequently triggering a range of downstream signaling pathways. In research, Metaproterenol hemisulfate salt has been employed as a tool to investigate the physiological and biochemical processes regulated by the beta-2 adrenergic receptor, including the modulation of smooth muscle tone, metabolic pathways, and gene expression. Its specific mechanism of action has provided valuable insights into the molecular mechanisms underlying cellular signaling and has been used to explain the role of the beta-2 adrenergic receptor in various physiological processes. Additionally, Metaproterenol hemisulfate salt has been utilized as a reference material in analytical chemistry, serving as a standard for the identification and quantification of beta-adrenergic agonists in various samples.
