CWHM-117
CWHM-117 is an orally active aspartic protease inhibitor with selective activity against Toxoplasma gondii. CWHM-117 inhibits the proliferation of Toxoplasma gondii tachyzoites in human fibroblasts, with an EC50 of 2.00 µM. CWHM-117 delays mortality in an acute mouse model of toxoplasmosis. In a chronic mouse model of toxoplasmosis, CWHM-117 reduces brain cyst burden and prolongs survival. CWHM-117 can be used for research on toxoplasmosis.

In Vitro
CWHM-117 (0.39-100 μM; 72 h) potently inhibits intracellular proliferation of T. gondii RH-2F1 tachyzoites in HFF cells with an EC50 of 2.00 μM[1].
CWHM-117 (0.39-100 μM; 72 h) has a CC50 of 14.30 μM against HFF cells, with a selectivity index of 7.15 for T. gondii tachyzoites[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
CWHM-117 (150 mg/kg/day; p.o.; once daily; 5 consecutive days) significantly reduces cerebral cyst burden in a murine chronic toxoplasmosis model, demonstrating activity against the latent bradyzoite stage[1].

-
Animal Model:Swiss mice (5-6 week old) were infected intraperitoneally with 2 × 105 freshly egressed T. gondii tachyzoites (RH strain)[1]
-
Dosage:150 mg/kg/day
-
Administration:p.o.; once daily; 10 consecutive days
-
Result:Delayed mortality, with treated animals surviving up to day 11 post-infection compared to vehicle-treated animals that succumbed between days 7 and 9 post-infection.
Showed no significant weight loss compared to the vehicle group.
-
Animal Model:Swiss mice (5-6 week old) were orally infected with 10 brain cysts of T. gondii (ME-49 strain)[1]
-
Dosage:150 mg/kg/day
-
Administration:p.o.; once daily; 5 consecutive days
-
Result:Caused a marked, statistically significant reduction in the number of brain cysts compared to the vehicle-treated group.
