The marine alkaloid oroidin along with a small library of reverse amide (RA) 2-aminoimidazoles were synthesized and assayed for anti-biofilm activity against PAO1 and PA14, two strains of the medically relevant γ-proteobacteriumPseudomonas aeruginosa. Analogues that contained a long, linear alkyl chain were more potent inhibitors than the natural product at preventing the formation of PAO1 and PA14 biofilms. The most active compound in the series was also shown to disperse established PAO1 and PA14 biofilms at low micromolar concentrations.
研究人员合成了海洋生物碱类拟橙皮甙以及一个小型的反向酰胺(RA)2-氨基咪唑库,并对PAO1和PA14这两种与医学相关的γ-绿脓杆菌菌株进行了抗生物膜活性测定。在防止 PAO1 和 PA14 形成生物膜方面,含有长线性烷基链的类似物比天然产物具有更强的抑制作用。该系列中活性最强的化合物还能在低微摩尔浓度下驱散已形成的 PAO1 和 PA14 生物膜。
