WR99210 is an orally active and low-toxicity dihydrofolate reductase (DHFR) inhibitor (IC50<0.075 nM). WR99210 shows good antiparasitic activity and is effective against P. falciparum and P. falciparum strains (including Pyrimethamine.html" class="link-product" target="_blank">Pyrimethamine (HY-18062)-resistant P. falciparum strains) as well as T. gondii[1][2][3]. | [Biochem/physiol Actions]
WR99210 is a potent inhibitor of Plasmodium falciparum dihydrofolate reductase (DHFR), which is a major malarial drug target. It has subnanomolar potency for the wild type, double mutant and quadruple mutant dihydrofolate reductases. | [in vivo]
WR99210 (1.25 mg/kg; i.p.; single daily for 5 days) is highly effective against T. gondii tachyzoites in a mouse model[1]. | Animal Model: | Male mice (T. gondii-infected)[1]. | | Dosage: | 1.25 mg/kg | | Administration: | Intraperitoneal injection; single daily for 5 days. | | Result: | Exhibited intraperitoneal parasite numbers were 2 logs less in mice on the day 5. |
