乙基嘧啶的合成衍生物，具有有效的抗疟特性。

A synthetic derivative of ethyl-pyrimidine with potent antimalarial properties; interferes with the regeneration of tetrahydrofolic acid from dihydrofolate by competitively inhibiting DHFR; has also been found to reduce the expression of SOD1.Parasite Infection Approved(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 IC50 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.

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 IC50 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.Cell Viability Assay 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.

Pyrimethamine (Pirimecidan; 1 mg/kg; i.g.; daily, for 10 d; female CF1 mice with T. gondii xenograft) combination of Fluconazole (HY-B0101) and Sulfadiazine (HY-B0273) increases protection from death. Animal Model:Female CF1 mice (18-22 g; 4-6 week of age) with T. gondii xenograft 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.
