Product Introduction
Bioactivity


英文名: SPR206 acetate

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.

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.

存储条件: Powder: -20°C for 3 years | In solvent: -80°C for 1 year
