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。
Norchelerythrine shows significant inhibitory activity against Staphylococcus aureus ATCC 6538 with MIC values ranging from 12.5 to 50 ug mL. It exhibits strong antifeeding activity in a concentration-dependant manner with the EC50 of 62.67 ppm.
Saccharocarcin A is an antibiotic originally isolated from S. aerocolonigenes subsp. antibiotica. It is active against M. luteus, S. aureus, E. coli, P. aeruginosa, and C. albicans in a disc assay. Saccharocarcin A inhibits C. trachomatis infection by 88% without inducing cytotoxicity in McCoy cells when used at a concentration of 0.5 μg ml.
