Verrucarin A (Muconomycin A) 是一种 D 型大环真菌毒素。Verrucarin A 是一种蛋白质合成 (protein synthesis) 的抑制剂,来源于Myrothecium verrucaria,可抑制白血病细胞系生长,并激活巨噬细胞 caspases、凋亡和炎症信号。Verrucarin A 能有效提高 p38 MAPK 的磷酸化,降低 ERK/Akt 的磷酸化。Verrucarin A 通过 p21 和 p53 的诱导引起细胞周期调控的解除。
产品描述 | Verrucarin A (Muconomycin A) is a Type D macrocyclic mycotoxin. Verrucarin A (VA), a protein synthesis inhibitor, derived from the pathogen fungus Myrothecium verrucaria, inhibits growth of leukemia cell lines and activates caspases and apoptosis and inflammatory signaling in macrophages. Verrucarin A effectively increased the phosphorylation of p38 MAPK and diminished the phosphorylation of ERK/Akt. Verrucarin A caused cell cycle deregulation through the induction of p21 and p53 [1] [2]. |
体外活性 | Verrucarin A (0-0.6 μM/ml; 24-48 hours)-induces time- and dose-dependent growth inhibition in the human breast cancer cell line MCF-7 cells [1]. Verrucarin A increases the levels of reactive oxygen species (ROS), and subsequently induces mitochondrial membrane potential (Δψm) loss, leading to the increase of Bax/Bcl-2 ratio, cytochrome c release, caspase activation, PARP degradation, and apoptosis [1]. Cell Viability Assay [1] Cell Line: MCF-7 cells Concentration: 0-0.6 μM/ml Incubation Time: 24 and 48 hours Result: Growth of MCF-7 cells is significantly inhibited in a dose- and time-dependent manner, with the IC 50 s of 0.41 and 0.29 μM/ml for 24- and 48-h treatment periods, respectively. |

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。
