生物活性:
Polymyxin B nonapeptide is a cyclic peptide obtained from Polymyxin B by proteolytic removal of its terminal amino acyl residue. Polymyxin B nonapeptide is less toxic, lacks bactericidal activity, and retains its ability to render gram-negative bacteria susceptible to several antibiotics by permeabilizing their outer membranes.
体内研究:
Polymyxin B nonapeptide (1.5, 3.0 mg/kg, 静脉注射, 连续 29 天) 在大鼠中没有表现出与硫酸多粘菌素 B 所观察到的神经肌肉阻断、神经毒性或肾毒性作用。
体外研究:
Polymyxin B nonapeptide (2-32 μg/mL, 24 h) 与 阿奇霉素 (HY-17506) 联用具有协同作用。Polymyxin B nonapeptide (10 μg/mL) 以浓度依赖的方式抑制脂多糖 (HY-D1056) 诱导的中性粒细胞启动。
