Propiverine hydrochloride

Propiverine hydrochloride (CAS No.: 54556-98-8) is a synthetic small molecule antimuscarinic and calcium modulatory research compound, generally classified within bladder smooth muscle pharmacology tools for mechanistic studies of detrusor overactivity and lower urinary tract dysfunction biology, with a functional profile characterized by inhibition of cholinergic signaling through muscarinic receptor blockade, most notably involving M3 dominated contractile pathways, together with calcium antagonistic effects that reduce stimulus induced smooth muscle contraction and support investigation of excitation contraction coupling, intracellular calcium handling, and downstream tone regulating networks; in preclinical experimental systems, reported pharmacological activity for muscarinic antagonism is commonly described in the nanomolar to micromolar range depending on assay format, receptor context, and tissue preparation, while effects on calcium dependent contractile responses are typically examined at low micromolar to higher micromolar concentrations, and the compound is therefore used as a reference or comparator agent in receptor pharmacology assays, isolated tissue contractility studies, cell based signaling analyses, and animal models designed to interrogate urinary storage dysfunction related phenotypes, where concentrations or doses used in experiments typically depend on specific experimental designs and research objectives, and where interpretation is focused on target engagement, pathway modulation, and translational biomarker discovery in biomedical research and drug discovery workflows rather than any non research use.
