We show that this simple technique allows fast and easy comparison of the binding affinity of arene ligands to cationic organometallic fragments. Graphical abstract The relative binding affinity of arene ligands has been investigated using Electrospray Ionisation Mass Spectrometry. The influence of arene ...

Its molecular structure was determined as Pr@D3h(14246)-C74(C6H3Cl2) by a combined mass spectrometry (MS), UV–visible-near-infrared (UV–vis-NIR) absorption spectroscopy, and quantum-mechanics characterization. Using the computed theoretical data, we evaluated the isomeric structures, metal-to-...
Molecular modeling suggests that five amino-acid substitutions in SrSHT result in four alterations in their predicted 3D structures. In particular, the conserved Lys402 adjacent to the DFGWG motif, and Cys200 in the crossover loop in SmSHT were replaced by Glu and Ser in SrSHT. These ...
Eggplant produces a variety of hydroxycinnamic acid amides (HCAAs) that have an important role in plant development and adaptation to environmental changes. In this study, we identified and characterized a spermidine hydroxycinnamoyl transferase (SHT) fr
Mass spectrometryUV-vis-NIRQuantum mechanics computationPr@C-74(C6H3Cl2), a novel dichlorophenyl-functionalized derivative of the Pr-containing monometallofullerene Pr@C-74, was successfully prepared and isolated. Its molecular-structure was determined as Pr@D-3h(14246)C-74(C6H3Cl2) by a ...
The minerals content of K, Ca, Na and Mg were determined by a flame atomic absorption spectrophotometer (FAAS) (M6, Termo Elemental, Waltham, MA, USA), respectively. The content of Fe and Cd in digestion solution were measured by inductively coupled plasma mass spectrometry (ICP-MS, Thermo ...
