Sulfathiazole (100 μg/mL in acetonitrile) 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 (100 μg/mL in acetonitrile) increases the production of 17-estradiol (E2) and has endocrine disrupting effects on aquatic organisms such as the Japanese medaka fish. Sulfathiazole (100 μg/mL in acetonitrile) is also a cathodic corrosion inhibitor. Sulfathiazole (100 μg/mL in acetonitrile) inhibits the corrosion of copper by chloride ions through chemical and physical adsorption on the copper surface, reduces the corrosion current density and shifts the corrosion potential negatively.

Description

Sulfathiazole (100 μg/mL in acetonitrile) 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 (100 μg/mL in acetonitrile) increases the production of 17-estradiol (E2) and has endocrine disrupting effects on aquatic organisms such as the Japanese medaka fish. Sulfathiazole (100 μg/mL in acetonitrile) is also a cathodic corrosion inhibitor. Sulfathiazole (100 μg/mL in acetonitrile) inhibits the corrosion of copper by chloride ions through chemical and physical adsorption on the copper surface, reduces the corrosion current density and shifts the corrosion potential negatively[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 sodium 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.

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.
