Silymarin (Silybin B) 是一种多酚类黄酮,是从水飞蓟或水飞蓟的种子中提取的一种 SARS-CoV-2 主蛋白酶抑制剂。它可降低肿瘤细胞的增殖,血管生成以及胰岛素抵抗,用于预防和治疗肝脏疾病,有潜力研究 COVID-19 。
产品描述 | Silymarin (Silybin B) (Silybin B) is a polyphenolic flavonoid that extracts from the milk thistle or seeds of Silybum marianum. It is used in the prevention and treatment of liver diseases. |
体外活性 | Mechanism of Silymarin involves different biochemical reactions, such as stimulation of the rate of ribosomal RNA synthesis by stimulating the transcription of polymerase I and ribosomal RNA genes, blockage of alpha-glycoside loops toxin intake, and protection of cell membranes from free radical-induced damage. Silymarin also displays a substantial protective effect against UVB-induced canceration at different stages, possibly through its strong antioxidant properties. |
体内活性 | The intravenous injection LD50 of Silymarin is 391.4 mg/kg, 70.1 mg/kg, 142.3 mg/kg for mice, rats, rabbits, respectively. |

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。
