p,p'-DDE
Based on 2 publication(s) in Google Scholar
p,p'-DDE (4,4'-DDE) is the major and persistent metabolite of DDT. p,p'-DDE is a orally active androgen receptor antagonist with an IC50 of 5 μM and a Ki of 3.5 μM. p,p'-DDE can affect the development and function of the male reproductive system. Additionally, high serum concentrations of p,p'-DDE may be a risk factor for type 2 diabetes in women.

Biological Activity
p,p'-DDE (0.2 μM) can effectively inhibit the transcriptional activity of the androgen receptor induced by androgens[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
p,p'-DDE (100 mg/kg; oral gavage; from 25-57 days old) can delay the onset of puberty in weanling male rats, while increasing their body weight and without reducing the serum testosterone levels[1].
p,p'-DDE (200 mg/kg; oral gavage; 4 days) can significantly reduce the weights of androgen-dependent seminal vesicles and prostates and alter related gene expression in 120-day-old male rats[1].

Solvent & Solubility
DMSO : 100 mg/mL (314.44 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (7.86 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Please enter the basic information of animal experiments:

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL. * In solvent : -80°C, 6 months; -20°C, 1 month (protect from light)
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
