IC50 & Target



In Vivo

In this study, the effectiveness of Sulfadiazine sodium and Pyrimetamine for the treatment of mice during acute infection with different atypical T. gondii strains was evaluated. Swiss mice were infected with seven T. gondii strainsl. The infected mice were treated with 10-640 mg/kg per day of Sulfadiazine sodium, 3-200 mg/kg per day of Pyrimetamine, or a combination of both drugs with a lower dosage. A descriptive analysis was used to assess the association between susceptibility to sodium and/or Pyrimetamine and the genotype. The TgCTBr4 and TgCTBr17 strains (genotype 108) presented lower susceptibility to sodium or Pyrimetamine treatment. The TgCTBr1 and TgCTBr25 strains (genotype 206) presented similar susceptibility to PYR but not sodium treatment. The TgCTBr9 strain (genotype 11) was the only strain with high susceptibility to treatment with both drugs [1].

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.
