Introduction of 108-78-1 :

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[1][2][3][4][5][6]. In Vitro: 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].
In Vivo: Note:
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].

1. Induction of acute nephrotoxicity[5]
Background
Melamine disrupts urinary metabolism and amino acid metabolism in a dose-dependent manner.
Specific Modeling Methods
Mice: Wistar rats
Administration: 100, 300, 600 mg/kg • p.o. • 15 days
Modeling Indicators
Molecular changes: Down-regulates 5-Hydroxytryptophan, decreases tyrosine, citric acid, and lowers blood uric acid levels.
Phenotypic observations: Increases kidney weight, crystal deposition in the renal papillary collecting ducts, and renal inflammation were observed.

Induction of cognitive deficits[6]
Background
Melamine impairs hippocampal function and inhibited differentiated PC12 cell proliferation.
Specific Modeling Methods
Rat: Wistar rats • Male • three-week-old
Administration: 300 mg/kg • p.o. • daily for 4 weeks.
Modeling Indicators
Neurology: Reduces excitatory postsynaptic potential in rats.
Behavioral observation: Induces symptoms of piloerection and haematuria as well as reduced spontaneous activity.
Opposite Product(s): Saralasin (HY-P0205); Prazosin (HY-B0193)

3. Induction of urinary stones[7]
Background
Induces transitional cell hyperplasia and ischemic changes in the kidney.
Specific Modeling Methods
Rat: F344/DuCrj rats • Male • six-week-old
Administration: 1 and 3% Melamine • p.o. • daily for 40 weeks.
Note
Melamine is added to powdered basal diet or 5 and 10% NaCl containing diet at concentrations of 1 and 3%.
Modeling Indicators
Histological analysis: Induces the decrease in kidney weight, promotes the formation of kidney stones, increases bladder weight and leads to focal lesions such as fibrosis, inflammatory cell infiltration, and tubular regeneration.
