Sulfadiazine sodium
Based on 8 publication(s) in Google Scholar
Sulfadiazine sodium is an orally active sulfonamide antibiotic. Sulfadiazine sodium competitively inhibits p-aminobenzoic acid in the folic-acid-metabolism cycle, inhibiting multiplication of most Gram-positive and many Gram-negative bacteria. Sulfadiazine sodium persists in soil long-term, and exerts selective pressure for sulfonamide-resistant microbial populations. Sulfadiazine sodium targets Toxoplasma gondii DHPS enzyme. Sulfadiazine sodium can be used for the research of congenital toxoplasmosis and bacterial infection.

Animal Model:Swiss Webster (female; weighing ~25 g; 6-8 months old; infected i.p. with 104 tachyzoites of different T. gondii strain)[3]
-
Dosage:10 mg/kg/d; 40 mg/kg/d; 160 mg/kg/d; 640 mg/kg/d
-
Administration:p.o.; daily for 10 days
-
Result:Showed the lowest treatment efficiency for TgCTBr4, the TgCTBr17 strain, whose mortality
reached 100% between 19 and 27 days at the dose of 10 mg/kg/d, 40 mg/kg/d, and160 mg/kg/d.
Significantly reduced the number of brain cysts in mice infected with other T. gondii (TgCTBr) strains, such as TgCTBr1, TgCTBr9, TgCTBr13, TgCTBr17 and TgCTBr25.

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.
