SPR206 acetate

产品编号 T39983 CAS 2408422-41-1

SPR206 acetate is a polymyxin analog that exhibits antibiotic activity against Gram-negative pathogens, including multidrug-resistant (MDR) variants. By interacting with the outer membrane of the bacterium, SPR206 acetate effectively combats bacterial infections. Notably, SPR206 acetate demonstrates significant efficacy with minimum inhibitory concentration (MIC) values of 0.125 mg/L against Pseudomonas aeruginosa Pa14 and Acinetobacter baumannii NCTC13301.

产品描述	SPR206 acetate is a polymyxin analog that exhibits antibiotic activity against Gram-negative pathogens, including multidrug-resistant (MDR) variants. By interacting with the outer membrane of the bacterium, SPR206 acetate effectively combats bacterial infections. Notably, SPR206 acetate demonstrates significant efficacy with minimum inhibitory concentration (MIC) values of 0.125 mg/L against Pseudomonas aeruginosa Pa14 and Acinetobacter baumannii NCTC13301.
靶点活性	Pseudomonas aeruginosa Pa14:0.125 mg/L (MIC), Acinetobacter baumannii (NCTC13301):0.125 mg/L (MIC)
体外活性	SPR206 exhibits strong anti-microbial properties against Gram-negative bacteria. The MIC values of SPR206 against E. coli IHMA558090, E. coli ATCC 25922, K. pneumonia ATCC 13882, P. aeruginosa ATCC 27853, A. baumannii NCTC13424 and A. baumannii ATCC 19003 are 8 mg/L, 0.125 mg/L, 0.125 mg/L, 0.25 mg/L, 0.06 mg/L and 0.125 mg/L, respectively, together with lower cytotoxicity[1].
体内活性	SPR206 (0.125-30 mg/kg; intravenous injection or subcutaneous injection; every 8 hours or every 4 hours; for 16 hours or 24 hours; neutropenic mice) treatment reduces the burden of Pa14 and NCTC13301 in lung tissue and in the thigh model[2]. Animal Model: Neutropenic mice infected Pa14 or NCTC13301[2]Dosage: 3 mg/kg, 10 mg/kg, 20 mg/kg, 30 mg/kg (intravenous injection); 0.125 mg/kg, 0.5 mg/kg, 1 mg/kg, 4 mg/kg (subcutaneous injection) Administration: Intravenous injection or subcutaneous injection; every 8 hours or every 4 hours; for 16 hours or 24 hours Result: In lung tissue, reduced the burden of Pa14 and NCTC13301 by 1.5 and 3.6 log 10 CFU/mL. In the thigh model, reduced the burden of Ab13301 by 3.4 and 4.3 log 10 CFU/g.

体内实验配液计算器

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。
