产品描述 | Piperlongumine (Piplartine) is a natural alkaloid from Piper longum L. It selectively kills cancer cells and strengthens the level of reactive oxygen species (ROS). |
体外活性 | Piperlongumine is a known ROS inducer which could induce pancreatic cancer cell death in cell culture[1] As a thromboxane A(2) receptor antagonist, Piperlongumine inhibits platelet aggregation. [2] Piperlongumine also promotes autophagy via inhibition of Akt/mTOR signalling and mediates cancer cell death. [3] |
体内活性 | Piperlongumine (50 mg/kg i.p.) causes in vivo growth inhibition of tumor cells without leading to major changes in the biochemical, hematological and histopathological parameters. [4] |
激酶实验 | MEK Kinase Assay: Kinase inactive murine ERK2 (mERK2) K52A/T183A is affinity purified from Escherichia coli expressed using the pET21a vector. MEK1 kinase activity is determined using mERK2 K52A T183A as the substrate. Recombinant MEK1 enzyme (5 nM) is first activated by 0.02 unit or 1.5 nM of RAF1 in the presence of 25 mM HEPES (pH 7.8), 1 mM MgCl2, 50 mM NaCl, 0.2 mM EDTA, and 50 μM ATP for 30 minutes at 25 °C. The reactions are initiated by adding 2 μM of mERK2K52A T183A and 2.5 μCi [γ-33P] ATP in a total volume of 20 μL. The MEK2 kinase activity is determined similarly except that activation by RAF1 is not needed and 11 nM of MEK2 enzyme (active) are used in the assays.Kinase profiling is performed by Invitrogen using their Select Screen Kinase Profiling Service. The Z'-LYTE biochemical assay is used. RDEA119 is assayed in quadruplicate at 10 μM against 205 kinases. |
细胞实验 | MCF-7 and 786-O cells are incubated with various PL concentrations for 48h. Cell proliferation is analysed by CellTiter Blue assay. Effective doses (ED) are calculated using XLift, Microsoft Excel add-in. (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。
