Isoetharine Mesylate

Isoetharine Mesylate (CAS No.: 7279-75-6) is a synthetic small molecule catecholamine derivative broadly categorized as a beta adrenergic receptor agonist and research tool compound for respiratory pharmacology, receptor signaling, and xenobiotic response studies, with reported activity at beta adrenergic pathways and additional evidence of pregnane X receptor activation linked to regulation of drug metabolizing enzyme expression including CYP450 associated programs; mechanistically, it is used to probe G protein coupled receptor driven adenylate cyclase activation and increased intracellular cAMP signaling, which in experimental systems is associated with smooth muscle relaxation biology, and as a catechol type substrate it is also relevant for metabolism studies involving catechol O methyltransferase mediated biotransformation, making it useful for integrated investigations of receptor pharmacodynamics and metabolic stability relationships; based on published characterization of this pharmacological class, in vitro functional responses are commonly described within nanomolar to micromolar concentration ranges depending on receptor context, assay format, and cell background, while PXR and downstream transcriptional effects are typically evaluated across concentration windows selected to balance pathway sensitivity and off target liability; in biomedical research and early drug discovery workflows, this compound is commonly applied in cell based assays of cAMP accumulation, beta receptor selectivity profiling, smooth muscle cell response phenotyping, and CYP related induction panels, and it may also be incorporated into animal model study designs focused on pharmacology and exposure response benchmarking, where the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
