产品描述 | Rifapentine (Rifapentinum) is a long-acting, cyclopentyl-substituted derivative of rifamycin used to treat mycobacterium infections. |
体外活性 | Rifapentine inhibits the function of DNA-dependent RNA polymerase in strains of M. tuberculosis, while inducing no effect on mammalian cells. Both Rifapentine and its active metabolite, 25-desacetylrifapentine, localize within monocyte-derived macrophages, thus allowing for intracellular inhibition of M. tuberculosis at a greater kill rate as compared with that of the parent or metabolite alone. Rifapentine is deacetylated in the liver and induces cytochrome P450 much less than rifampin. [1] Rifapentine has shown higher bacteriostatic and bactericidal activities (MICs and MBCs) than RMP, especially against intracellular bacteria growing in human monocyte-derived macrophages. [2] |
体内活性 | Rifapentine inhibits bacterial RNA synthesis by binding to the β-subunit of DNA-dependent RNA polymerase in susceptible species. Rifapentine is generally more active than rifampicin against sensitive strains of M. tuberculosis. [3] Rifapentine significantly increases the rate of antipyrine and pentobarbital metabolism in vivo. Rifapentine also increases liver weight, the content of liver microsomal protein and cytochrome P-450, the activity of NADPH-cytochrome C reductase and NADPH oxidase. [4] Rifapentine combined with isoniazid (INH) and pyrazinamide (PZA) administered daily results in an apparent clearance of M.tuberculosis organisms in the lungs and spleens of infected mice after 10 weeks of treatment.

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。
