Product Description
Propylparaben (Propyl parahydroxybenzoate) is an antibacterial preservative that can be generated by plants and bacteria. Propylparaben is widely used in cosmetics, pharmaceuticals and foods. Propylparaben disrupts follicular growth and steroidogenic function by altering cell cycle, apoptosis and steroidogenic pathways. Propylparaben also reduced sperm count and motility in rats.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Isolated adult rat cardiomyocytes are shielded from ischemia-reperfusion damage by propylparaben. The effects of 15 hours of reperfusion and 45 minutes of continuous ischemia-induced cell death are considerably lessened by propylparaben (500 μM; 10 minutes) [4]. Voltage-gated sodium channels are reversibly blocked by propylparaben (250 μM, 500 μM) in a concentration- and voltage-dependent way [4]. In mature 3T3-L1 white adipocytes, propylparaben (0-1 μM; 48 hours) inhibits basal lipolysis, including insulin-stimulated glucose uptake. However, it won't alter the 2-NBDG's basic intake [5].
ln Vivo
In eight months, female mice treated with propylparaben (7.5 mg/kg/day; oral; treated for eight months) showed dramatic changes in hormone levels, ovarian reserve, and estrous cycles. In addition, adult mice's ovarian aging was accelerated. According to studies, melatonin administration can stop the malfunction of granulosa cell steroid synthesis caused by propylparaben [6].

Solubility Data
Solubility (In Vitro)
DMSO : ~125 mg/mL (~693.67 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (11.54 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.08 mg/mL (11.54 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Solubility in Formulation 3: ≥ 2.08 mg/mL (11.54 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

5 mM 1.1099 mL 5.5494 mL 11.0988 mL
10 mM 0.5549 mL 2.7747 mL 5.5494 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
