产品描述 | Paederosidic acid has significant anti-tumor, anticonvulsant and sedative effects. Paederosidic acid increases brain gamma-aminobutyric acid and decreases glutamic acid in the brain, and it up-regulates expressions of GAD 65, may be a promising future therapeutic agent for treatment of epilepsy. |
体外活性 | Paederosidic acid(PA) showed significant anti-tumor activity on lung cancer in vitro; the mechanisms were involved in inducing mitochondria-mediated apoptosis via up-regulation of caspase-3, caspase-8, caspase-9, Bid, Bax, down-regulation of Bcl-2 and stimulating the release of Cyto-C from mitochondria.JNK phosphorylation levels significantly increased concomitantly with decrease in Akt phosphorylation after treatment with PA in A549 cells. However, JNK siRNA-transfected cells diminished PA-induced caspase-3, 8 and 9, Bid and Bax activaton while enhanced the Bcl-2 activation. PA-induced JNK activation played an important functional role in apoptosis[1]. |
体内活性 | Anticonvulsant and sedative effects of paederosidic acid isolated from Paederia scandens (Lour.) Merrill. in mice and rats.Paederosidic acid (5, 10, 20, and 40 mg/kg, ip) had significant anticonvulsant and sedative effects. paederosidic acid increased brain gamma-aminobutyric acid and decreased glutamic acid in the brain, and it up-regulated expressions of GAD 65. Paederosidic acid may be a promising future therapeutic agent for treatment of epilepsy[2]. |
细胞实验 | The anti-proliferative effects of PA on A549 cells were evaluated by MTT method and the IC50 values were calculated. Furthermore, the PA-induced apoptosis in A549 cells was determined by fluorescence microscope via staining with DAPI and by flow cytometer via staining with FITC conjugated Annexin V/PI. The expression of apoptosis-related or signaling proteins was investigated by Western blotting[1] |
动物实验 | Anticonvulsant activities of paederosidic acid were evaluated by maximal electroshock and pentylenetetrazole-induced seizures in male mice. Then, pentobarbital sodium-induced sleeping time and locomotor activity tests in mice were used to evaluate the sedative effects of paederosidic acid. Finally, the mechanism of paederosidic acid was explored by evaluating the contents of Glu and GABA in the brain, and Western blot was used to measure GAD65 expression in the mouse brain[2]. |

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。
