产品描述 | Cytembena is a cytostatic and a carcinogenic compound that may increase the incidence of fibroadenomas.Cytembena broadly inhibits DNA biosynthesis. |
体内活性 | Cytembena was given i.p. in doses of 5, 10, 20, 40, and 80 mg/kg body wt. to Wistar rats and in doses of 20, 40, and 80 mg/kg body wt. to ICR mice and to Chinese hamsters. Five patients with various types of malignancy, so far medically untreated, received 20 mg Cytembena/kg body wt i.v. A combination of Cytembena and cyclophosphamide was applied i.p. in single equal doses 1: 1 of 5,10, 20, and 40 mg/kg body wt to ICR mice, Chinese hamsters, and Wistar rats. Patients were given i.v. 20 mg Cytembena and 20 mg cyclophosphamide/kg body wt. Bone marrow cells were examined 24 h after the administration. The frequency of abnormal metaphases and chromosomal breaks after Cytembena treatment was low; nonetheless, the indicated dose-effect relationship was found in all the rodents used. The frequency of chromosomal breaks was 2-3 times higher in rodents in comparison with men, after treatment with a dose of 20 mg Cytembena/kg body wt. The highest frequencies of induced aberrations were found in mice. The rodents appeared to be 3--4 times more sensitive to the induction of chromosomal breaks and abnormal metaphases than men, after a dose of 20 mg Cytembena and 20 mg cyclophosphamide/kg body wt.[1] |

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。
