(R)-5-Hydroxymethyl Tolterodine

Desfesoterodine, also known as PNU-200577, is a major pharmacologically active metabolite of tolterodine, a new muscarinic receptor antagonist intended for the treatment of an overactive bladder. In vitro, PNU-200577 produced a competitive and concentration-dependent inhibition of carbachol-induced contraction of guinea-pig isolated urinary bladder strips (KB = 0.84 nM; pA2 = 9.14). In vivo, PNU-200577 was significantly more potent at inhibiting acetylcholine-induced urinary bladder contraction than electrically induced salivation in the anaesthetised cat (ID50 15 and 40 nmol.kg-1, respectively; P < 0.01).

How to use

In Vitro:

In vitro, Desfesoterodine preventes carbachol-induced contraction of guinea-pig isolated urinary bladder strips in a competitive and concentration-dependent manner. 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.

In Vivo:

Desfesoterodine (PNU-200577; 5-Hydroxymethyl Tolterodine; 0.1 and 1 mg/kg; IV) significantly increases bladder compliance after moderate and high doses. 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).
