产品描述 | Bismuth Subcitrate is an antibiotic used to treat stomach ulcers associated with Helicobacter pylori, a bacterial infection. |
靶点活性 | C. pyloridis:8 ug/ml (MIC50) |
体外活性 | Colloidal Bismuth Subcitrate is crystallized in dilute HCl at pH 3, and unique assembly of three basic bismuth citrate dimeric units ([Bi(cit)2Bi]2-) leads to the formation of two-dimensional sheets and 3D polymer, the solubility of Colloidal Bismuth Subcitrate in water is found to be dramatically affected by pH, from >70 mg/mL at pH 7 to only about 1 mg/mL at pH 3. [1] Bismuth Subcitrate is effective against the 12 C. pyloridis strains with MIC50 of 8 μg/mL. Bismuth Subcitrate combined with oxolinic acid exhibits synergistic activity against the 12 C. pyloridis strains. [2] Colloidal bismuth subcitrate (5 mg/mL) significantly increases the frequencies of sister-chromatid exchange (SCE) and micronucleus rate in peripheral lymphocytes compared with controls in human whole blood cultures. [3] Bismuth Subcitrate (100 μM) inhibits Helicobacter pyloriF1-ATPase activity, and inhibition is prevented and reversed by the mercaptan glutathione, indicating that Bismuth Subcitrate interfere with sulfhydryl groups of the enzyme. [4] Colloidal Bismuth Subcitrate (150 mg/mL) inhibits the lipolytic activity of C. pylori filtrate, causing a 21% reduction in lipase activity and a 60% reduction in the activity of phospholipase A.

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。
