    體外研究
    (In Vitro)

    The discovery of the first competitive progesterone antagonist, Mifepristone, has stimulated an intense search for more potent and more selective antiprogestins[1]. Cell growth is evaluated after 4 days of exposure to Mifepristone at 10 μM, a concentration close to the plasma concentration achievable in humans. The antiproliferative effect of NSC 119875 is potentiated when administered in combination with Mifepristone in HeLa cells. The IC50 of NSC 119875 in combination with Mifepristone is lower (14.2 μM) than that of NSC 119875 alone (34.2 μM) in HeLa cells with an approximately 2.5-fold difference. After treatment with Mifepristone, the accumulation of intracellular NSC 119875 in HeLa cells is 2-fold greater, representing a significant difference (p=0.009), compare with NSC 119875 alone from 0.79 to 1.52 μg/mg of protein[2].

    體內(nèi)研究
    (In Vivo)

    The cervix tumor xenograft models are treated with NSC 119875 alone, there is a tumor growth inhibition compare with control group. However, the tumor weight loss is even more significant (p<0.05) with the combination of NSC 119875 and Mifepristone at the doses used, showing a decrease of ~50% compared with the treatments alone by the end of the study[2]. Adult male Sprague-Dawley rats are subjected to a 4-day binge-like EtOH administration regimen (3 to 5 g/kg/i.g. every 8 hours designed to produce peak blood EtOH levels (BELs) of <300 mg/dL). Subgroups of animals receive s.c. injection of Mifepristone (20 or 40 mg/kg in peanut oil). Although Mifepristone produces no significant changes in behavior of EtOH-na?ve animals, pretreatment with Mifepristone (40 mg/kg) significantly reducesthe severity of EtOH withdrawal. Asignificant interaction between diet and drug, F(5,55)=3.92, p<0.05, such that EtOH-treated animals receiving vehicle or 20 mg/kg of Mifepristone displayssignificantly more signs of EtOH withdrawal than does EtOH-na?ve animals receiving the same drug treatment. Importantly, treatment with 40 mg/kg of Mifepristone significantly reduces the severity of EtOH withdrawal, in a dose-dependent manner[3].

    Cell Assay
    [2]

    The HeLa and CaSki human cervical cancer cell lines are used. The effect of Mifepristone on proliferation of cells exposed to NSC 119875 is evaluated using the XTT assay. The assay is based on the cleavage of the yellow tetrazolium salt XTT to form an orange formazan dye by metabolically active cells. The procedure is as follows. Cells are seeded into 96-well plates; Costar at a density of 6×103 viable cells per well in 100 μL culture medium. At the end of treatment with NSC 119875 alone or the combination of NSC 119875 plus Mifepristone, 50 μL XTT is added to each well (final concentration 0.3 mg/mL), follow by incubation for 4 h in a humidified atmosphere containing 5% CO2 at 37?C. The absorbance of the samples is measured spectrophotometrically at 492 nm using a microtiter plate ELISA reader[2].

    Animal Administration
    [2][3]

    Mice[2]
    Female Nude mice between 6-8 weeks of age are implanted subcutaneously with 6×106 HeLa cells in a flank. Once tumors are ~5×5 mm, the animals are pair-matched into treatment and control groups. Each group consist of 8 tumor-bearing mice. The intraperitoneal administration of drugs or vehicle begin on day 0. NSC 119875, as a single agent, is administered intraperitoneally at a dose of 3 mg/kg daily on days 1 through 3; the dose of Mifepristone, as a single agent, is 2 mg/kg/day subcutaneously for 3 days; in the combination study, the mice concurrently receive NSC 119875 on the same schedule, and Mifepristone at the same dose 3 days previous to the administration of NSC 119875. The control animals receive only the vehicle. After administration of the drugs, mice are weighed and the tumors are measured with a caliper twice weekly. The tumor weight is calculated. Experiment is conducted for 74 days, after which time all animals are weighed and humanely euthanized.
    Rats[3]
    Adult male Sprague-Dawley rats, weighing between 224 and 245 g upon arrival, are used. Mifepristone (20 or 40 mg/kg) or vehicle (peanut oil) are administered subcutaneously (s.c.) once daily following the 0800 administration of EtOH or control diet. Mifepristone is suspended in peanut oil and sonicated for 30 minutes at least 24 hours prior to injection, it is then stored at 4°C until needed. Suspension is vortexed for 10 to 15 minutes prior to and as needed throughout dosing.

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
