A set of molecules including a majority of metal‐N‐heterocyclic carbene (NHC) complexes (metal=Ag, Cu, and Au) and azolium salts were evaluated by high‐throughput screening of their activity againstbiofilmformation associated with pathogenicbacteria. The anti‐planktonic effects were compared in parallel. Representative biofilm‐forming strains of various genera were selected (Listeria, Pseudomonas
通过高通量筛选它们对与病原菌相关的生物膜形成的活性,评估了包括大多数金属-N-杂环卡宾(NHC)配合物(金属= Ag,Cu和Au)和盐的一组分子。并行比较了抗浮游生物的作用。选择了不同属的代表性生物膜形成菌株(李斯特菌,假单胞菌,葡萄球菌和大肠埃希氏菌)。所有化合物均以1 mg L -1进行测试通过使用BioFilm环形测试。根据标准化实验值确定信息得分(IS,活性总和)和活性得分(AS,抗生物膜和抗浮游生物活性之间的差异),以根据细菌菌株对活性最高的分子进行分类。通过这种方法,我们确定了在NHC配体上具有芳族基团的亲脂性Ag I和Cu I络合物是抑制生物膜形成的最有效方法。

We report here the synthesis and catalytic evaluation in DNA alkylation of a series of water‐soluble coppercomplexes bearing N‐heterocycliccarbene (NHC) ligands. The NHC ligands were chosen to cover the gamut of commonly used scaffold variations, but in many cases, coppercomplexes could not be obtained or were unstable. Nevertheless, we identified several complexes that were both stable and catalytically

The catalytic hyperpolarisation of pyridine, 3-hydroxypyridine and oxazol by the Signal Amplification By Reversible Exchange (SABRE) process is achieved by a series of water soluble iridium phosphine and N-heterocyclic carbene dihydride complexes.
The facile synthesis of functionalized luminescent nanoparticles from LnL3 lanthanide complexes is described. The luminescence properties of the lanthanide chelates and of the corresponding nanohybrids are reported and compared. For a further application in bioimaging, the cytotoxicity of the nano-objects was investigated.
