Self-Association of Organic Solutes in Solution: A NEXAFS Study of Aqueous Imidazole [PDF]

, 2015
N K-edge near-edge X-ray absorption fine-structure (NEXAFS) spectra of imidazole in concentrated aqueous solutions have been acquired. The NEXAFS spectra of the solution species differ significantly from those of imidazole monomers in the gas phase and ...

Magnesium and imidazole propionate

Clinical Nutrition ESPEN, 2021
Circulating levels of imidazole propionate (ImP), a microbial metabolite of histidine, were higher in participants with type 2 diabetes (T2D) compared to those without and also induced insulin resistance. We hypothesize that low intake of magnesium (Mg) and/or low body Mg status in humans may lead to low Mg concentrations in gut microbiota, and, in ...

Imidazole and Imidazolium Antibacterial Drugs Derived from Amino Acids

Pharmaceuticals, 2020
The antibacterial activity of imidazole and imidazolium salts is highly dependent upon their lipophilicity, which can be tuned through the introduction of different hydrophobic substituents on the nitrogen atoms of the imidazole or imidazolium ring of ...

Modeling solid state stability for speciation: a ten-year long study [PDF]

, 2019
Speciation studies are based on fundamental models that relate the properties of biomimetic coordination compounds to the stability of the complexes. In addition to the classic approach based on solution studies, solid state properties have been recently
