产品描述 | Ketoconazole (R-41400), a CYP3A4 inhibitor, is an imidazole anti-fungal agent. |
靶点活性 | Cyclosporine oxidase:0.19 mM, Testosterone 6β-hydroxylase:0.22 mM |
体外活性 | 腹腔注射Ketoconazole(25 mg/kg)后,大鼠体内血浆皮质酮浓度明显降低,也可使低剂量可卡因自我给药减少.Ketoconazole处理组大鼠,地高辛生物有效性得到提高,从0.68提高至0.84 ,而平均吸收时间从1.1 h减少至0.3 h.此外,地高辛的口服AUC值也得到提高,从63 mg·h/L提高至411 mg·h/L.地高辛的静脉注射AUC值也被提高,从93 mg·h/L提高至486 mg·h/L. |
体内活性 | 在HT29-S-B6结肠癌细胞中,Ketoconazole剂量依赖性地降低细胞增殖,[3H]胸苷渗透,IC50为2.5 mM。在Evsa-T细胞系和MDA-MB-231 细胞系中,Ketoconazole抑制[3H]胸苷渗透,IC50 分别为2 μM 和13 μM。在HT29-S-B6细胞中,Ketoconazole在24 h内,剂量依赖性地诱导S期细胞数减少(从17%降低至3%),Go-G1期细胞百分数则相应增加(从64% 增加至80%)。通过与[3H]Dexamethasone竞争性结合的方式,Ketoconazole能够抑制成纤维细胞糖皮质激素受体,IC50为0.3 mM。几种马拉色霉菌种对Ketoconazole较为敏感,最小抑制浓度为0.03 μg/mL。 |
激酶实验 | Whole Cell [3H]R1881 Binding Assay: Fibroblasts are grown to confluence in five or six 150 cm2 tissue culture flasks for routine assay. This usually requires 4-6 weeks from the time of the initial seeding of the cell line. All studies are performed between passages 3-20. Two days before assay, the medium is changed to one lacking fetal calf serum. This is repeated again 24 hours before assay. Competition assays are performed with 0.5-1.0 nM [3H]R1881 and increasing amounts of the nonradioactive compounds. Binding to low affinity sites is determined in the presence of 5 × 10-7 M R1881 and is subtracted from whole cell binding of [3H]R 1881 obtained in the absence of any inhibitor to assess binding to 5 high affinity site |
细胞实验 | HT29-S-B6 cells (5×105) are plated in 35-mm Petri dishes. The next day, the medium is changed and effectors are added in a small volume (10-20 μL). The incubation medium is renewed every day during the experiments. The same triplicate dishes are used for cell counts, [3H]thymidine incorporation, and flow cytometry. [3H]Thymidine (0.5 μCi) is allowed to incorporate for 24 hours; at the end of incubation, cells are rinsed with 1 mL of medium, detached with 1 mL of trypsin-EDTA, and diluted (1:3) with the culture medium. An aliquot (0.5-1 mL) is used for cell count with a Coulter Counter.(Only for Reference) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
