产品描述 | Cefuroxime Sodium is the sodium salt form of cefuroxime and a semi-synthetic, broad-spectrum, beta-lactamase resistant, second-generation cephalosporin antibiotic with bactericidal activity. Cefuroxime sodium (Cefuroxime sodium salt) inhibits bacterial cell wall synthesis by inactivating penicillin binding proteins (PBPs) thereby interfering with the final transpeptidation step required for cross-linking of peptidoglycan units which are a component of the cell wall. Lack of cross-linking results in a reduction of cell wall stability and leads to cell lysis. |
体内活性 | The intravenous LD50 of cefuroxime sodium for mice is 10.4 g/kg. The maximum dosage administered in other acute toxicity tests is well tolerated by mice (10 g/kg, subcutaneous), by rats (4 g/kg, intravenous, 5 g/kg, subcutaneous) and by cats, dogs and monkeys (2 g/kg, intramuscularly). However, when cefuroxime sodium is administered subcutaneously (s.c.) or intramuscularly (i.m.) for 3 months to rats (100, 300 or 900 mg/kg/day) followed by a recovery period, and also for 6 months to rats and dogs (50, 150 or 450 mg/kg/day) and for 1 month to monkeys (150 or 450 mg/kg/day), there are no serious toxic effects in all tests. In rats large doses cause some increase in urine volume and electrolyte excretion, and slightly aggravates an age related nephropathy. Administration to rats intravenously (i.v.) for 1 month of up to 400 mg/kg/day has no toxic effects. In reproduction studies on mice and rabbits there are no adverse effects on fertility, organogenesis or the rearing of young[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。
