产品描述 | Cefazaflur is a novel semi-synthetic cephalosporin derivative that can be used as an Antibiotic agent. |
体外活性 | Cefazaflur was tested in vitro against 262 strains of bacteria. When tested in agar, 5.0 mug or less of cefazaflur per ml inhibited almost all strains of Staphylococcus aureus, Escherichia coli, Klebsiella, and Proteus mirabilis. The drug was less active against Enterobacter and indole-positive Proteus, and 7.5 mug of antibiotic per ml inhibited approximately two-thirds to one-fourth of the strains. A concentration of 50 mug of cefazaflur per ml was required for inhibition of the enterococci. There was negligible activity against Pseudomonas. The drug demonstrated less activity in broth than in agar, and a major inoculum effect was seen with some strains. For example, with a lower inoculum, 2.5 mug of cefazaflur per ml killed all strains of E. coli, whereas with the higher inoculum, 7.5 mug of cefazaflur per ml, inhibited 64% and killed only 8% of strains.[1] |

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。
