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.

antibiotics and constitute a significant health threat. 2‐Aminobenzimidazole derivatives (see scheme) are capable of stronglyinhibiting the growth of and dispersing Pseudomonas aeruginosa biofilms. These molecules were found to modulate quorum sensing in reporter strains, and represent some of strongest P. aeruginosa biofilm inhibitors known.
The invention relates to a method for preventing or treating a disease or disorder that is associated with the MrgX2 receptor. The invention also relates to MrgX2 antagonists and physiologically acceptable salts thereof. The invention also relates to pharmaceutical compositions and dosage forms comprising an MrgX2 antagonist.
A series of novel benzimidazole substituted Schiff bases were synthesized by reaction of aromatic aldehydes with corresponding 2-aminobenzimidazoles. Their structure has been studied by 1H and 13C NMR, IR and UV/Vis spectroscopy. Majority of prepared Schiff bases were tested on their antiproliferative activity in vitro and exerted non-specific antiproliferative activity on the tested cell lines at
通过芳族醛与相应的2-氨基苯并咪唑反应,合成了一系列新型的苯并咪唑取代的席夫碱。通过1 H和13 C NMR,IR和UV / Vis光谱研究了它们的结构。 测试了大多数制备的席夫碱的体外抗增殖活性,并在最高测试浓度下对所测试的细胞系发挥了非特异性的抗增殖活性。化合物18和19对所有细胞系均表现出最强的非特异性抗增殖作用,并且在微摩尔浓度下对HeLa和MCF-7细胞系具有浓度依赖性,但同时对人成纤维细胞也具有高度的细胞毒性。
