Compounds described herein inhibit biofilm formation or disperse pre-formed biofilms of Gram-negative bacteria. Biofilm-inhibitory compounds can be encapsulated or contained in a polymer matrix for controlled release. Coatings, films, multilayer films, hydrogels, microspheres and nanospheres as well as pharmaceutical compositions and disinfecting compositions containing biofilm-inhibitory compounds are also provided. Methods for inhibiting formation of biofilms or dispersing already formed biofilms are provided. Methods for treating infections of gram-negative bacteria which form biofilms, particularly those of Pseudomonas and more particularly P. aeruginosa.
本文所述化合物可抑制革兰氏阴性细菌生物膜的形成或驱散已形成的生物膜。生物膜抑制化合物可封装或包含在聚合物基质中,以实现控制释放。此外,还提供了含有生物膜抑制化合物的涂层、薄膜、多层膜、水凝胶、微球和纳米球以及药物组合物和消毒组合物。还提供了抑制生物膜形成或驱散已形成的生物膜的方法。提供了治疗形成生物膜的革兰氏阴性细菌感染的方法,特别是假单胞菌感染,尤其是铜绿假单胞菌感染。
