A second-generation library of 2-aminoimidazole-based derivatives incorporating a "reversed amide" (RA) motif in comparison to the marine natural product oroidin were synthesized and subsequently assayed for antibiofilm activity against the medically relevant Gram-negative proteobacteria P. aeruginosa and A. baumannii. Most notably, an in-depth activity profile is reported for the most active subclass
合成了第二代基于2-氨基咪唑的衍生物,与海洋天然产物oroidin相比,该衍生物结合了“反向酰胺”(RA)主题,随后针对医学上相关的革兰氏阴性菌铜绿假单胞菌和铜绿假单胞菌鲍曼不动杆菌 最值得注意的是,据报道,活性最高的衍生物亚类具有更深的活性,这些亚类的酰胺键上带有线性脂族链。另外,核心模板的进一步结构修饰,例如酰胺键的去除或三唑等排物的取代,导致发现了具有抗生物膜活性的类似物,其对铜绿假单胞菌和铜绿假单胞菌的抑制和分散特性各不相同。鲍曼生物膜。
