Pirenzepine-d₈ dihydrochloride  (Synonyms: LS 519-d₈ dihydrochloride; Pirenzepin-d₈ dihydrochloride; Gastrozepin-d₈ dihydrochloride)

Pirenzepine-d₈ (LS 519-d₈; Pirenzepin-d₈) dihydrochloride is a deuterium labeled Pirenzepine (dihydrochloride) (HY-17037). Pirenzepine (LS 519) dihydrochloride is a selective M1 mAChR (muscarinic acetylcholine receptor) antagonist. Pirenzepine dihydrochloride reduces gastric acid secretion and reduces muscle spasm, can be used in peptic ulcers research. Pirenzepine dihydrochloride shows anti-proliferative activity to cancer cells^[1][2][3].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
