产品描述 | 9-Methoxycamptothecin (MCPT) has antitumour activities through topoisomerase inhibition. |
体外活性 | 9-Methoxycamptothecin(MCPT) induced cytotoxicity in seven human cancer cell lines in a dose dependent manner after 72h, with A2780 and Hela cell lines more sensitive, so the two cell lines were chosen to do further studies. MCPT induced strong G2/M arrest in both A2780 cells and Hela cells after 24h, following by substantial sub-G1 arrest (indicating apoptosis). The apoptosis was verified by staining with Annexin V-FITC and propidium iodide. ROS generation increased significantly in MCPT-induced apoptosis. Meanwhile, the apoptosis appeared to be dependent on caspase-3, -8 and -9 in A2780 cells, and caspase-3 in Hela cells. In addition, MCPT induced up-regulation expression of most of seventeen genes in both cell lines. Western blot verified that changes of TNFα, Fas, P53 and P27 protein level were consistent with their gene expression changes[1]. |

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。
