Tiotropium-d3 bromide
Stable Isotope
Tiotropium-d3 bromide is a deuterium-labeled variant of Tiotropium bromide, a selective antagonist of muscarinic acetylcholine receptors (mAChRs). By inhibiting acetylcholine binding, it prevents the opening of ligand-gated ion channels, leading to bronchial dilation. This compound is primarily used in pharmacological studies related to respiratory disorders and can be utilized in isotopic labeling experiments to investigate drug metabolism and pharmacokinetics.
