Sulfathiazole is an orally active, endocrine disruptor targeting the steroidogenic pathway, specifically enhancing the activity of CYP19 in human adrenal cancer cells (H295R) and upregulating the mRN expression of CYP17, CYP19, and 3β-HSD. Sulfathiazole increases the production of 17-estradiol (E2) and has endocrine disrupting effects on aquatic organisms such as the Japanese medaka fish.

Description

Sulfathiazole is an orally active, endocrine disruptor targeting the steroidogenic pathway, specifically enhancing the activity of CYP19 in human adrenal cancer cells (H295R) and upregulating the mRN expression of CYP17, CYP19, and 3β-HSD. Sulfathiazole increases the production of 17-estradiol (E2) and has endocrine disrupting effects on aquatic organisms such as the Japanese medaka fish[1][2][3].

In Vitro

Sulfathiazole (0.02-20 mg/L; 48 h) can significantly increase the production of 17-estradiol (E2), aromatase (CYP19) activity, and mRNA expression of steroidogenesis-related genes such as CYP17, CYP19, and 3βHSD in human adrenal cancer cell (H295R) experiments[1].
Sulfathiazole can effectively inhibit the corrosion of copper in 0.1 M NaCl solution, and the inhibition efficiency can reach more than 80% with increasing concentration[3].

Cell Viability Assay[1]

Cell Line: H295R cells
Concentration: 0.2 mg/L, 2 mg/L
Incubation Time: 48 h
Result: Exposure to 0.2 mg/L and 2 mg/L Sulfathiazole for 48 h upregulated the mRNA expression of CYP17, CYP19, and 3βHSD2, which are key genes involved in the steroidogenic pathway.
In Vivo

Sulfathiazole (50 mg/L, 500 mg/L; water exposure; daily feeding; 14 days) significantly increases plasma 17-estradiol (E2) concentrations in male Japanese medaka (Oryzias latipes) models[1].
Sulfathiazole (1%; mixed in purified feed; daily intake) causes a decrease in polymorphonuclear neutrophils, band cells, and metamyelocytes in the bone marrow, necrosis and calcification of skeletal muscle, calcification or hyalinization of pulmonary/coronary/renal arteries, hydropic degeneration and focal hyaline necrosis of hepatocytes, hyaline necrosis of adrenal cortical cells, thyroid hyperplasia, and hemorrhage in subcutaneous tissues, body cavities, and organs in Wistar and Osborne-Mendel albino rat models during and shortly after weaning[2].

Animal Model: Male Japanese medaka (Oryzias latipes), 3-4 months old[1]
Dosage: 50 mg/L, 500 mg/L (water)
Administration: Waterborne exposure with ad libitum feeding of Artemia nauplii twice daily, renewed exposure medium at least three times per week for 14 d
Result: After 14-d exposure, plasma E2 concentrations in male medaka were significantly increased to 1.56 ng/mL (50 mg/L) and 2.06 ng/mL (500 mg/L), which were 1.32-fold and 1.75-fold higher than the control (1.18 ng/mL), respectively.

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 5 mg/mL (19.58 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 5 mg/mL (19.58 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
