生物活性

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.

体外研究(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.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

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.
体内研究(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.

Medlife 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
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.
运输条件

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
