产品描述 | Ledaborbactam etzadroxil (VNRX-7145) is an orally active inhibitor of Ambler class A, C, and D β-lactamase enzymes. |
体内活性 | Upon dosing the Ledaborbactam etzadroxil (VNRX-7145) in mice, dogs, and monkeys, Ledaborbactam etzadroxil (5-10 mg/kg) demonstrates the most consistent oral bioavailability across species (F = 61-82%)[1]. In intestinal S9, Ledaborbactam etzadroxil is rapidly cleaved with short half-lives in all species with the exception of beagle dogs. The half-life in human plasma is short at about 11 min, which is closer to what was observed in the rodent species compared to the longer half-lives in dogs (43.9 min) and monkeys (22.0 min)[1]. In vivo efficacy is demonstrated in a lethal murine septicemia model by dosing Ledaborbactam etzadroxil (orally) with Ceftibuten. The ED 50 value of 12.9 mg/kg[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。
