Biological Activity

Description Ulipristal is a selective SPRM for emergency contraception after an unprotected intercourse or contraceptive failure.
Targets
Progesterone receptor [1]
In vitro

Ulipristal acetate has partial agonistic as well as antagonistic effects on the progesterone receptor. It also binds to theglucocorticoid receptor, but has no relevant affinity to the estrogen, androgen and mineralocorticoid receptors.[1]

In vivo Based on clinical trials, ulipristal acetate seems to be a reasonably tolerable and effective method of emergency contraception when used within 120 hours of intercourse. Ulipristal acetate is at least as effective as LNG when used within the first 72 hours after unprotected intercourse. However, ulipristal acetate may be more effective than LNG when used between 72 to 120 hours after unprotected intercourse, extending the window of opportunity for emergency contraception. [2][3]

Protocol

Solubility (25°C)

In vitro DMSO 83 mg/mL (191.42 mM)
Ethanol 14 mg/mL (32.28 mM)
Water Insoluble

* 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
    Concentration
    Volume
    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 )

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.
