Eurycomalactone 是一种NF-κB 抑制剂,IC50=0.5 μM,是一种天然产物。它可抑制蛋白合成,降低 cyclin D1 蛋白水平,但对 TNFα 诱导的 IκBα 降解或 IKKα/β 和 IκBα 的磷酸化水平没有作用。

产品描述 | Eurycomalactone is a natural product isolated from Eurycoma longifolia Jack., acts as a potent NF-κB inhibitor( IC50 of 0.5 μM). Eurycomalactone inhibits protein synthesis, depletes cyclin D1, but does not affect TNFα-induced degradation of IκBα or the phosphorylation of IKKα/β and IκBα. |

体外活性 |
Eurycomalactone (ECL), an active quassinoid isolated from Eurycoma longifolia Jack, has been demonstrated to possess anticancer activity.?ECL exhibited selective cytotoxicity against the NSCLC cells A549 and COR-L23 compared to the normal lung fibroblast.?Clonogenic survival results indicated that ECL treatment prior to irradiation synergistically decreased the A549 and COR-L23 colony number.?ECL treatment reduced the expression of cyclin B1 and CDK1/2 leading to induce cell cycle arrest at the radiosensitive G /M phase.?Moreover, ECL markedly delayed the repair of radiation-induced DNA double-strand breaks (DSBs).?In A549 cells, pretreatment with ECL not only delayed the resolving of radiation-induced γ-H2AX foci but also blocked the formation of 53BP1 foci at the DSB sites.?In addition, ECL pretreatment attenuated the expression of DNA repair proteins Ku-80 and KDM4D in both NSCLC cells.?Consequently, these effects led to an increase in apoptosis in irradiated cells.?Thus, ECL radiosensitized the NSCLC cells to X-ray via G /M arrest induction and delayed the repair of X-ray-induced DSBs. It has?a great potential for ECL as an alternative safer radiosensitizer for increasing the RT efficiency against NSCLC[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。
