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.
Terephthalic acid can be used in animal modeling to create skin tumor models. In experiments, Terephthalic acid is administered orally to weanling and adult mice, exhibiting distinct pharmacokinetic features. Terephthalic acid is metabolized in the body to form calcium terephthalate or calcium hydrogen terephthalate, leading to oversaturation in the urine and promoting the formation of bladder stones. The lithogenic effect of Terephthalic acid is more pronounced in weanling mice than in adults, and its effect on bladder stone formation is more significant at higher doses (1000 mg/kg/day), with no noticeable effects observed at a dose of 142 mg/kg/day. The safe dosage range for Terephthalic acid in terms of inducing lithogenesis is: oral administration not exceeding 0.5 mg/kg/day, and a total concentration in drinking water not exceeding 3 mg/L.
Administration: 10 μg/mouse • topical application • refer to the note for details on the administration method
(2) DMBA and Terephthalic acid combined administration: Shave the backs of 8-10 week old mice, first apply DMBA (HY-W011845) (25 μg per mouse, dissolved in 200 μL of acetone) to the shaved dorsal skin, then apply Terephthalic acid (10 μg per mouse, dissolved in 200 μL of acetone) on the 3rd day after the first DMBA treatment.
(3) After 4 rounds of the above DMBA and Terephthalic acid combined treatment, mice receive Terephthalic acid (10 μg per mouse, dissolved in 200 μL of acetone) alone twice weekly for 20 weeks.

Konzentration (Stammlösung) × Volumen (Stammlösung) = Konzentration (Ziellösung) × Volumen (Ziellösung)
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 90% (20% SBE-β-CD in Saline)
Solubility: 2 mg/mL (12.04 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
