Pseudomonas aeruginosa produces a biofilm that provides the bacteria with an effective barrier against antibiotics. Here, we investigated the synergy of various antibiotics with 14-alpha-lipoyl andrographolide (AL-1), focusing upon synthesis of the biofilm. AL-1 also inhibited the production of the exopolysaccharide and pyocyanin components. We propose that AL-1 may potentially serve as a cotherapy to combat P. aeruginosa.
铜绿假单胞菌产生生物膜,为细菌提供了对抗生素的有效屏障。在这里,我们研究了各种抗生素与 14-α-硫辛酸穿心莲内酯(AL-1)的协同作用,重点是生物膜的合成。AL-1 还抑制了胞外多糖和绿脓菌素成分的产生。我们提出,AL-1 可能具有作为联合治疗来对抗铜绿假单胞菌的潜力。
