(R)-Hydroxytolterodine-d14
(R)-Hydroxytolterodine-d14 is deuterated labeled Desfesoterodine (HY-76569). Desfesoterodine (PNU-200577) is a potent and selective muscarinic receptor (mAChR) antagonist with a KB and a pA2 of 0.84 nM and 9.14, respectively. Desfesoterodine is a major pharmacologically active metabolite of Tolterodine (PNU-200583; HY-A0024) and Fesoterodine (HY-70053). Desfesoterodine improves cerebral infarction induced detrusor overactivity in rats.

Biological Activity
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].
In vitro, Desfesoterodine preventes carbachol-induced contraction of guinea-pig isolated urinary bladder strips in a competitive and concentration-dependent manner[2].
In radioligand binding studies carries out in homogenates of guinea-pig tissues and Chinese hamster ovary cell lines expressing human muscarinic m1-m5 receptors, Desfesoterodine is not selective for any muscarinic receptor subtype[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In vivo, Desfesoterodine is significantly more potent at suppressing acetylcholine-induced urinary bladder contraction than electrically induced salivation in the anaesthetised cat (ID50=15 and 40 nmol/kg, respectively) [2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
