Avibactam sodium hydrate (NXL-104 hydrate) 是 β-内酰胺酶的共价可逆抑制剂,不含β-内酰胺核心 。Avibactam sodium hydrate 抑制 β-内酰胺酶CTX-M-15和TEM-1,IC50分别为5 nM 和 8 nM。
产品描述 | Avibactam sodium hydrate (NXL-104 hydrate) is a covalent and reversible inhibitor of β-lactamase that does not contain a β-lactam core. Avibactam sodium hydrate inhibits β-lactamase CTX-M-15 and TEM-1 with IC 50 s of 5 nM and 8 nM, respectively. |
体外活性 | Avibactam sodium hydrate (NXL-104 hydrate) is a molecule with little antibacterial activity, that inhibits class A and C β-lactamases. Avibactam inactivates most important β-lactamases except metallo types and Acinetobacter OXA carbapenemases [2]. |
体内活性 | Avibactam sodium hydrate (NXL-104 hydrate) displays a slow return of activity with an off-rate of 0.045±0.022 min -1, which converts to a residence time half-life (t t1/2 ) of 16±8 min. The measured off-rate for Avibactam suggests that slow deacylation through hydrolysis or reversibility is occurring, and it is in contrast to previously reported extremely long t 1/2 values of >1 or >7 d for Avibactam inhibition of TEM-1 [1]. Avibactam is a new promising β-lactamase inhibitor, to overcome resistance caused by β-lactamases. Mice are infected with ca.10 6 CFU of Pseudomonas aeruginosa intramuscularly into the thigh or intranasally to cause pneumonia and are given 8 different (single) subcutaneous doses of GR20263 and Avibactam in various combined concentrations, ranging from 1 to 128 mg/kg of body weight in 2-fold increases. The mean estimated half-life in plasma of GR20263 in the terminal phase is 0.28 h (SD, 0.02 h), and that of Avibactam is 0.24 h (SD, 0.04 h). Volumes of distribution are 0.80 liters/kg (SD, 0.14 liters/kg) and 1.18 liters/kg (SD, 0.34 liters/kg), respectively [3]. |

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。
