Based on 1 publication(s) in Google Scholar
Melamine is an orally active inducer of Apoptosis. Melamine induces animal disease models. Melamine affects the activity of Sertoli cell and can be used for research on male reproductive function. Melamine also has neurotoxicity and nephrotoxicity. Melamine induces cognitive impairment and acute kidney injury models. Melamine can also be used to induce bladder cancer and urinary stone models.

Actividad biológica
Melamine (0-1000 g/mL, 24 h) suppresses cell viability and induces cell apoptosis in concentration-dependent manner in Sertoli cells[1].
Melamine (50 g/mL, 24 h) down-regulates the expressions of junction-associated proteins including occludin, N-cadherin, and vimentin, suggesting that MA disrupts the integrity of Sertoli cell barrier[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.
Melamine (300 mg/kg, p.o., daily, 28 days) is able to impair the learning and memory abilities and reduces rats weight [2].
Melamine (60-600 mg/kg, p.o., daily, 2 weeks) impairs endothelial function and increases pro-inflammatory and pro-fibrotic markers in renal arteries of rats dose-dependently[3].
PK parameter of Melamine. The half-life (t1/2) is 32.2-32.9 hours, the clearance (Clz/F) is 35.9-36.6 mL/h/kg, and the volume of distribution (Vss) is 1.67-1.74 L/kg[8].
Melamine can be used in animal modeling to construct models of acute nephrotoxicity, cognitive deficits, and urinary stone formation[5][6][7].
Administration: 100, 300, 600 mg/kg • p.o. • 15 days
Phenotypic observations: Increases kidney weight, crystal deposition in the renal papillary collecting ducts, and renal inflammation were observed.
Administration: 300 mg/kg • p.o. • daily for 4 weeks.
Behavioral observation: Induces symptoms of piloerection and haematuria as well as reduced spontaneous activity.
Administration: 1 and 3% Melamine • p.o. • daily for 40 weeks.

Solvente y solubilidad
DMSO : 10 mg/mL (79.29 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 1 mg/mL (7.93 mM; Need ultrasonic)
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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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: ≥ 1.25 mg/mL (9.91 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.25 mg/mL (9.91 mM); Clear solution
