Trihexyphenidyl-d 5 hydrochloride is deuterium labeled Trihexyphenidyl hydrochloride. Trihexyphenidyl hydrochloride is a selective and orally active M 1 muscarinic receptor antagonist with an IC50 of 3.7 nM for rat cerebral cortex M1 muscarinic receptors. Trihexyphenidyl hydrochloride modulates cholinergic activity, countering acetylcholine supersensitivity in neural pathways. Trihexyphenidyl hydrochloride improves movement disorder, inhibits McN-A-343 -induced pressor responses, vagally-induced bradycardia and vasodilatation. Trihexyphenidyl hydrochloride can be used for the research of Parkinson's disease. [1] [2] [3].
In Vitro, 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.
