Sofpironium bromide

Sofpironium bromide (CAS No.: 1628106-94-4) is a synthetic small molecule anticholinergic agent used as a pharmacological research tool in life sciences programs focused on cholinergic regulation of exocrine gland function, where it is broadly categorized as a muscarinic acetylcholine receptor modulator with primary functional activity associated with inhibition of M3 receptor mediated signaling in sweat gland biology and with reported high affinity across additional muscarinic receptor subtypes including M1, M2, M4, and M5, thereby supporting mechanistic studies of acetylcholine dependent secretory pathways, receptor subtype contribution, and downstream calcium linked signal transduction in peripheral non neuronal tissues; in biomedical research and early drug discovery workflows, this compound is commonly applied in cell based assay systems and translational preclinical models to investigate receptor pharmacology, target engagement, and structure activity relationships within anticholinergic chemical space, while quantitative potency outputs should be interpreted from assay specific datasets and are generally discussed in broad terms such as nanomolar to micromolar activity ranges for muscarinic receptor pathway modulation when direct standardized values are not available, and experimental concentrations or administered doses are typically selected according to model context, endpoint sensitivity, exposure design, and overall research objectives.
