|Description||Ethynodiol diacetate is one of the first synthetic progestogens used in contraceptive pills.|
Nordihydroguaiaretic acid (NDGA) (< 1.5 μM) decreases the percentage of sister chronnatid exchanges (SCEs) in human lymphocyte culture treated with ethynodiol diacetate (150 μg/mL). Since the NDGA treatment, in the presence of S9 mix, reduce the genotoxic damage by ethynodiol diacetate, the reduction may be due to the inhibition of cytochrome P450s which prevents the metabolic activation of ethynodiol diacetate or NDGA may act as a free radical scavenger.  Ethynodiol diacetate (150 μg/mL) increases sister chromatid exchanges (SCEs) and chromosomal aberrations (CAs) frequencies and inhibits lymphocyte proliferation in the presence of S9 mix in human lymphocyte. 
|In vivo||Ethynodiol diacetate (6 mg/kg b.w. daily) significantly increases the amounts of excreted 3alpha-hydroxy-5alpha-pregnan-20-one and A-homo-3-oxa-5alpha-pregnane-4,20-dione in urine in female rats. Significant increase in the weights of pituitary, liver and kidneys are noted in rats treated with ethynodiol diacetate (6 mg/kg b.w. daily).  Norgestrel (75 μg/day) and ethynodiol diacetate (150 μg/day), co-administered with ethinyl estradiol (7.5 μg/day), lowers the plasma concentrations of HDL cholesterol in cynomolgus monkeys. |

* 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.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × 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.
