体外研究

Brequinar reduces virus progeny production by >90%, with EC50 of 17nM. Brequinar (5μM) also inhibits other orthopoxviruses, and blocks virus DNA replication.Brequinar does not affect virus early gene expression, but has a severe effect on the late stage of the virus cycle. Brequinar reduces the level of envelope protein production and the viral titer in a dose-dependent manner,with EC50 of 78nM in the CFI assay. Brequinar (5μM) inhibits viral RNA synthesis.Brequinar has antiviral effect, but the effect is reversed by pyrimidine. Brequinar-resistant viruses can be selected in cell culture. Brequinar (5μM) suppresses the luciferase activities from both the WT and NS5 mutant replicons. Brequinar sodium effectively prevents the increase in PyNTP levels with an IC50 of 0.26μM. Brequinar sodium effectively inhibits cell proliferation with an IC50 of 0.26μM. Brequinar sodium inhibits autophosphorylation of p56lck with IC50 of 70μM; inhibition is 39, 41, and 60% for 25, 50, and 100μM Brequinar sodium,respectively. Brequinar sodium also inhibits the phosphorylation by p56lck of the exogenous substrate, histone 2B, with an IC50 of 70μM; inhibition is 10, 43, 59, and 86% for 25,50, 100, and 200μM Brequinar sodium,respectively. Brequinar sodium inhibits autophosphorylation of p59fyn with an IC50 of 105μM; inhibition is 0, 17, 48, and 65% for 25,50,100, and 200μM Brequinar sodium, respectively. Brequinar sodium also inhibits the phosphorylation by p59fyn of histone 2B with an IC50 of 20μM; inhibition is 26, 54, 79, 83, and 84% for 10, 25, 50, 100, and 200μM Brequinar sodium, respectively.

体内研究

Brequinar sodium-treated (10-20mg/kg/day) mice has a 31% reduction in percentage of packed cell volume compared with urequinar sodium-treated (10-20mg/kg/day) mice has a 31% reduction in percentage of packed cell volume compared with untreated BALB/c mice. Brequinar sodium reduces UTP and CTP levels in bone marrow cells by 30 and 25%, respectively.Brequinar sodium (10-20mg/kg/day) in combination with uridine (1000-2000mg/kg/day) prevents anemia, and the hematocrits remain at levels (61-63%) comparable with those of untreated controls.

 

推荐实验方法(仅供参考)

激酶实验:

Immunoprecipitated p59fyn or p56lck from CTLL-4 cells or LSTRA cells (5×106) is preincubated with various concentrations of BQR in the PTK buffer (50 mM HEPES (pH 7.4), 10mM MgCl2, and 10mM MnCl2) on ice for 10min. Exogenous substrate,histone 2B (2μg), is added and, after 10min, the reaction is initiated by addition of 10μCi [γ-32P]ATP. After incubation at 20℃ for 10min, the reaction mixture is subjected to electrophoresis in a 12.5% SDS-polyacrylamide gel.Phosphorylation of the kinase and the exogenous substrate is analyzed by autoradiography.

 

细胞实验:

 

The neutral-red uptake assay is used to evaluate cell viability. BSC-40 cells are seeded in 96-well plates in the presence of concentrations of Brequinar ranging from 0.01μM to 75μM for 24h.Control cells are incubated with 0.1% DMSO. Neutral red is methanol/acetic acid-extracted from cells and is quantitated at an absorbance of 490nm (A490). All measurements expressed the average of four independent assays.

 

动物实验:

 

Brequinar is administered once daily by i.p. injection, while uridine is administered twice daily.Mice are bled through the orbital vein using a microhematocrit capillary tube, and the blood is centrifuged for 10min at 550 × g. The percentage of packed cell volumes is determined with a microhematocrit capillary tube reader. All mice are killed 4 h after receiving their last dose of Brequinar or uridine.
