Background | Dihydroartemisin is an effective antimalarial compound. Dihydroartemisini can inhibit NF- κ B activation to induce autophagy and apoptosis. |
Biological Activity | Dihydroartemisinin是一种有效的抗疟疾 (anti-malaria) 药物。[1-3] |
IC50 | 33.6 ± 6.8mmol/l(BxPC-3 cells);49.9± 7.0mmol/l(AsPC-1 cells)[4] |
In Vitro | 双氢青蒿素(DHA)是抗疟药。双氢青蒿素处理有效地上调细胞溶质RelA/p65蛋白水平并下调核RelA/p65蛋白水平。双氢青蒿素阻断RelA/p65从胞质溶胶中的核转位,而不是抑制RelA/p65蛋白质合成。双氢青蒿素诱导RPMI 8226细胞中的自噬。双氢青蒿素抑制RPMI 8226细胞中的NF-κB活化。通过EMSA测定检查NF-κB双氢青蒿素结合活性。将RPMI 8226细胞暴露于各种浓度的双氢青蒿素(10,20和40μM)12小时,并引入TNF-α作为NF-κB活化的阳性对照。与TNF-α相比,双氢青蒿素以剂量依赖性方式抑制NF-κB活化[1]。双氢青蒿素(DHA)可增强光动力疗法(PDT)对食管癌细胞的抗肿瘤作用,并使用MTT试验研究细胞活力。用双氢青蒿素(80μM),PDT(分别为25和20J/cm 2)或它们的组合处理Eca109和Ec9706细胞。用双氢青蒿素或PDT单独治疗导致Eca109细胞活力降低37±5%或34±6%,Ec9706细胞降低33±7%或34±6%。然而,当PDT与双氢青蒿素合用时,细胞活力分别降低了59±6%或61±7%[2]。用 MTT 法测定 DHA 对 BxPC-3 和 AsPC-1 细胞活力的影响。 与未处理的细胞相比,DHA 以剂量依赖的方式降低了与 DHA 一起孵育 72 小时的两种细胞的活力。 通过简单的线性回归分析,计算出 BxPC-3 细胞与 DHA 一起孵育 72 h 时的 IC50 为 33.6 ± 6.8 mmol/l; AsPC-1 细胞的 IC50 为 49.9± 7.0 mmol/l。[4] |
In Vivo | 单次口服双氢青蒿素(200,300,400或600 mg/kg),感染后第6-8天给予一次,使总蠕虫负荷减少69.2%-90.6%,雌虫负荷减少62.2% %-92.2%,取决于第一次实验中的剂量。在感染后第34-36天给予类似治疗,使总蠕虫负担减少73.9%-85.5%,雌虫负荷减少83.8%-95.3%[3]。 |
Cell Experiment | Eca109(4×103细胞/孔)和Ec9706(5×103细胞/孔)细胞在96孔板中生长并培养过夜以允许细胞附着。用双氢青蒿素(80μM),PDT(分别为25和20J/cm 2)或它们的组合处理Eca109和Ec9706细胞。温育24小时后,向各孔中加入MTT(20μL)并在37℃下温育4小时。将Formazan晶体在150μLDMSO中振荡溶解10分钟。在读板器上在490nm处测量吸光度,并且实验重复三次[2]。 |
Animal Experiment | 小鼠[3]使用昆明菌株的小鼠,每只重20-24g。在第一个实验中,设计研究了多剂量的双氢青蒿素对日本血吸虫和成虫的影响,小鼠每天给予三次剂量,200,300,400或600毫克双氢青蒿素/ kg(剂量体积为感染后第6-8天或第34-36天分别为25 mL/kg)。另一组感染但未给予药物的小鼠作为对照。 |
Kinase Experiment | 为了确定NF-κB双氢青蒿素结合活性,进行电泳迁移率变动分析(EMSA)。制备核提取物并与来自HIV长末端重复的5'-TTGTTACAAGGGACTTTCCGCTG GGGACTTTCCAGGGAGGCGTGG-3'的32P-末端标记的45-mer双链寡核苷酸(15μg蛋白质和16fmol DNA)一起孵育(粗体表示NF-κB结合)在37°C下保持30分钟。形成的双氢青蒿素 - 蛋白质复合物与6.6%天然聚丙烯酰胺凝胶上的游离寡核苷酸分离。双链突变寡核苷酸5'-TTGTTACAA CTCACTTTCCGCTGCTCACTTTCCAGGGAGGCGTGG-3'用于检测NF-κB与DNA的结合特异性。还通过与未标记的寡核苷酸竞争来检查结合特异性。包括免疫前血清(PIS)作为阴性对照。使用Storm 820对干燥的凝胶进行可视化,并使用Imagequant软件对放射性带进行定量[1]。 |
