Summary
Pyrimethamine (Pirimecidan) is a potent, orally active dihydrofolate reductase (DHFR) inhibitor. Pyrimethamine is an antimalarial agent. Pyrimethamine affects the nucleoprotein metabolism of malarial parasites by interference in the folic–folinic acid systems and affects cell division by inhibiting the conversion of dihydrofolate to tetrahydrofolate [1] [2] .
In Vitro
Pyrimethamine (Pirimecidan; 4 nM-4 μM; 24 h; LLC-MK2 cells with T. gondii ) combination of Fluconazole (FLZ) (HY-B0101) inhibits T. gondii activity with IC 50 values of 0.23, 0.19, 0.23, 0.34, 0.14, and 0.19 μM for FLZ concentration at 0, 0.05, 0.1, 0.5, 1.0, and 3.0 μM, respectively [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Viability Assay [1]
| Cell Line: | LLC-MK2 cells with T. gondii |
| Concentration: | 4 nM-4 μM |
| Incubation Time: | 24 hours |
| Result: | Inhibited T. gondii activity and decreased parasite proliferation index. |
In Vivo
Pyrimethamine (Pirimecidan; 1 mg/kg; i.g.; daily, for 10 d; female CF1 mice with T. gondii xenograft) combination of Fluconazole (FLZ) (HY-B0101) and Sulfadiazine (HY-B0273) increases protection from death [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
| Animal Model: | Female CF1 mice (18-22 g; 4-6 week of age) with T. gondii xenograft [1] |
| Dosage: | Oral gavage; daily, for 10 days |
| Administration: | 1 mg/kg; 10 mg/kg ( Fluconazole (HY-B0101)), 40 mg/kg ( Sulfadiazine (HY-B0273)) |
| Result: | Increased mouse survival compared to treatment with SDZ/PYR alone. |
