SPR206 is a polymyxin analogue and an important class of antibiotic for the treatment of bacterial infections due to multidrug resistant Gram-negative pathogen.
Lipopolysaccharides from P. aeruginosa (Pseudomonas aeruginosa) 10 是一种来自铜绿假单胞杆菌 (P. aeruginosa 10) 的脂多糖内毒素和TLR4激活剂,属于 S 型 LPS。此化合物具有典型的三部分结构:O 抗原、核心寡糖和脂质 A。同时,它的脂肪酸组成异于常见的肠杆菌,磷酸化程度异常高(检测到三磷酸残基),并具有独特的核心寡糖外部区域,其 O 特异性侧链通常富含新型氨基糖。此脂多糖对病毒具易感性,高分子量多糖的含量直接影响其易感性,而这些多糖的缺失会增强其对噬菌体的敏感性。
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.
