Biological Activity

Description Fesoterodine Fumarate is a prodrug of 5-hydroxymethyl tolterodine that is a muscarinic AChR receptor antagonist, used to treat overactive bladder syndrome.
AChR [1]
In vitro

Fesoterodine is rapidly and extensively converted to 5-HMT, such that the pharmacologic activity appears to be primarily attributable to 5-HMT. [1] Fesoterodine is a competitive antagonist of cholinergic agonist-stimulated responses in human M1-M5 cell lines and has a similar potency and selectivity profile to the radioligand-binding studies. Fesoterodine causes a rightward shift of the concentration-response curve for carbachol with no depression of the maximum in rat bladder strips, and concentration-dependently reduces contractions induced by electrical field stimulation (EFS). [2] Fesoterodine is hydrolyzed by nonspecific esterases to 5-hydroxmethyl tolterodine (5-HMT), which is the active metabolite and is responsible for all its antimuscarinic activity. [3]


Solubility (25°C)

In vitro DMSO 100 mg/mL (189.51 mM)
Water 100 mg/mL (189.51 mM)
Ethanol 100 mg/mL (189.51 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.

Bio Calculators

Molarity Calculator

Molarity Calculator

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)

  • Mass
    Molecular Weight

*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).

Dilution Calculator

Dilution Calculator

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 )

  • C1

* 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.
