|Description||5-hydroxymethyl tolterodine (PNU 200577) is a new muscarinic receptor antagonist with Kb of 0.84 nM.|
|Features||A competitive antagonist at the muscarinic receptors.|
5-hydroxymethyl tolterodine is a major pharmacologically active metabolite of tolterodine. 5-hydroxymethyl tolterodine produces a competitive and concentration-dependent inhibition of carbachol-induced contraction of guinea-pig isolated urinary bladder strips. 5-hydroxymethyl tolterodine antagotizes muscarinic receptors with a pA2 of 9.1. 5-hydroxymethyl tolterodine causes a concentration-dependent inhibition of (-)3 H-QNB binding in homogenates of guinea-pig urinary bladder, parotid gland, heart and cerebral cortex.  5-hydroxymethyl tolterodine has a similar pharmacological profile with tolterodine.  Intravenous infusion of 5-hydroxymethyl tolterodine produces a dose-dependent inhibition of the intravesical volume-induced urinary bladder contraction measured as the micturition pressure. 
|In vivo||5-hydroxymethyl tolterodine is significantly more potent at inhibiting acetylcholine-induced urinary bladder contraction than electrically induced salivation in the anaesthetised cat (ID50 15 and 40 nmol/kg, respectively. 5-hydroxymethyl tolterodine is three times more potent at the urinary bladder compared to the salivary gland. |
|In vitro||DMSO||68 mg/mL (199.12 mM)|
|Ethanol||68 mg/mL (199.12 mM)|
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
