Cell lines | Human foreskin fibroblasts (HFFs, ATCC SCRC-1041) cells |
Preparation Method | The T. gondii tachyzoites were maintained by repeat passage in monolayers of HFFs grown in DMEM supplemented with 10% (v/v) FBS and a cocktail of 1% (v/v) penicillin-streptomycin -glutamine at 37 ℃ and 5% CO2. |
Reaction Conditions | GSK J4 HCl with initial concentration of 100 μM in the culture medium was added to the first column of HFFs (~ 250 cells/well) in a 96-well half-area plate and then diluted serially across the plate by 2-fold dilutions, leaving the final column drug-free. Fifty tachyzoites were then added at a MOI of 1:5 to each well in six of the eight rows. After a 72h incubation, CPRG was added, and the absorbance was measured at 570 nm. Moreover, to measure the effect of each compound on the viability of host cells, CCK8 reagent was added to the two rows of uninfected HFFs and absorbance at 450 nm was measured after 2 h. |
Applications | GSK-J4 HCl could inhibit T. gondii and show ability against toxoplasmosis. |
Animal models | Female BALB/c mice (6–8 weeks old, ~20 g) |
Preparation Method | Mice were divided into 4 groups consisting of 15 mice each and injected intraperitoneally with 103 RH strains per animal. GSK J4 HCl were dissolved in DMSO and diluted in PBS prior to feeding to mice. After 4 h of infection, mice were orally administered with GSK J4 HCl for 5 consecutive days and were monitored for 30 days. Mice treated with pyrimethamine (50 mg/kg) were used as a positive control, and 1 ml PBS containing 11 μl of DMSO was used as a negative control. |
Dosage form | 50 mg/kg |
Applications | GSK J4 HCl could significantly elongate the survival time in acute murine toxoplasmosis model. GSK-J4 HCl is a promising candidate for the treatment and prevention of toxoplasmosis. |
产品描述 | GSK-J4 HCl is a small-molecule inhibitor with highly efficient cell permeability and a pharmacologically selective inhibitor that preserves H3K27 methylation by inhibiting KDM6B. GSK-J4 HCl acts by interacting with α-ketoglutarate binding at the catalytic site of KDM6B. In addition, treatment with GSK-J4 HCl induced cell cycle arrest and cell death in different kinds of cancer cells with dismal toxicity to normal cells. In vitro experiment indicated that GSK-J4 HCl could inhibit T. gondii at IC50 values of 2.37 μM. In addition, the TD50 value of GSK-J4 HCl against HFF was 34.6 μM. Based on these results, the calculated in vitro TI was 14.6 for GSK-J4 HCl. These data suggest that GSK-J4 HCl is a potent drug candidate against toxoplasmosis. In vivo study indicated that GSK J4 HCl could significantly elongate the survival time in acute murine toxoplasmosis model. Moreover, GSK-J4 HCl is a promising candidate for the treatment and prevention of toxoplasmosis.[1] References: |
