Isopropamide Iodide

Isopropamide Iodide (CAS No.: 71-81-8) is a synthetic small molecule in the quaternary ammonium anticholinergic class that is broadly categorized as a pharmacological tool compound for gastrointestinal physiology and cholinergic signaling research, with functional relevance as a long acting muscarinic receptor antagonist that attenuates acetylcholine mediated smooth muscle excitation and secretory activity, thereby supporting mechanistic studies of parasympathetic regulation in digestive systems and related receptor biology; within biomedical research and early drug discovery workflows, it is commonly positioned in receptor pharmacology and pathway interrogation programs focused on muscarinic GPCR signaling, including downstream calcium mobilization and phospholipase linked signaling processes, and it is also used as a reference modulator when profiling compounds in cell based assays that model hypermotility, secretory dysfunction, or broader cholinergic imbalance, while published quantitative potency values are not consistently reported across standardized modern assay platforms and are therefore generally interpreted at qualitative to semiquantitative levels, with experimentally active exposure windows often handled in the micromolar domain and, depending on assay format and endpoint sensitivity, potentially extending toward lower concentration ranges in optimized systems; typical applications include target engagement and functional antagonism studies in engineered receptor expressing cells, smooth muscle or epithelial in vitro models, and exploratory in vivo pharmacology models of gastrointestinal function, where the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives, and all use is limited to controlled laboratory research contexts rather than any form of human use or non research consumption.
