产品描述 | (20S)-Protopanaxadiol (20-Epiprotopanaxadiol) (20-Epiprotopanaxadiol), an apoptosis inducer, is an aglycon metabolic derivative of the protopanaxadiol-type ginseng saponin. |
体外活性 | Concentrations causing growth inhibition of 50% of cells (LC50) for the compounds PPD is 23 μg/ml, for Int-407 cells. The the LC50 for PPD is determined to be 24 μg/ml in Caco-2 cells. In the Int-407 cell line, PPD produces great percentage of sub-G1 (apoptotic) cells(The Int-407 cell line is a human embryonic nonmalignant cell line originating from fetal tissue of approximately 2 months gestation, whereas Caco-2 is a human colon adenocarcinoma cell line). This response is attributed to differences in individual ginsenoside glycosylation and, thus, the hydrophobic-hydrophilic balance [2]. Incubation with PPD also significantly reduces the viability of U251-MG and U87-MG cells in a dose- and time-dependent manner. The cytotoxic effect of PPD is accompanied by reduced expression of cell adhesion proteins, including N-cadherin and integrin β1, which leads to reduced phosphorylation of focal adhesion kinase. Furthermore, incubation with PPD reduces the expression of cyclin D1 and subsequently induces cell-cycle arrest at the G1 phase[3]. |
体内活性 | Treatment with PPD(20(S)-Protopanaxadiol) and PPT(20(S)-Protopanaxatriol) prior to immobilization stress increase the time spent in open arms and open arm entries in the elevated plus-maze (EPM) test. Treatment with PPD potently suppresses immobilization stress-induced serum levels of corticosterone and interleukin (IL)-6 by the enzyme-linked immunosorbent assay. PPD and PPT may exhibit the anxiolytic effect via γ-aminobutyrateA (GABAA) receptor(s) and serotonergic receptor(s), respectively, and PPD may have an anti-inflammatory effect that is more potent than that of PPT[1]. |
细胞实验 | Int-407 and Caco-2 cells are seeded at a concentration of 1×106 cells/mL in 24-well plates in separate experiments. Test ginsenosides (PPD, PPT, Rh2) are added to wells to the LC50 concentration determined previously from the MTT assays. The ginsenoside concentrations used for Int-407 cells are 23, 26, and 53 μg/mL, respectively, for PPD, PPT, and Rh2. In a similar experiment using Caco-2 cells, 24 μg/mL for both PPD and PPT and 55 μg/mL for Rh2 is used. Untreated cells represented the control. Cells are incubated at 37℃ in a 5% CO2 humidified incubator for 24, 48, and 72 h. Cell-free supernatant are obtained by centrifugation(400 g) for 10 min, and the lactate dehydrogenase (LDH) assay is conducted as previously reported.(Only for Reference) |

对于不同动物的给药剂量换算,您也可以参考 更多...
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。
