The carbonyl functional groups were protected by methoximation using 10 μl of a 40 mg/ml methoxyamine hydrochloride in pyridine (Sigma-Aldrich) at 30°C for 90 min. To increase the volatility of the metabolites, 90 μl of N-methyl-N-(trimethylsilyl) trifluoroacetamide (Fluka, St. Louis,...
to quantitatively validate predictions of the spatial and temporal evolution of concentrations by comparison with experimental data.The chemical reaction selected for this study was the reversible formation of a complex between Ni2+ions and the bidentate ligand pyridine-2-azo-p-dimethylaniline (PADA). ...
The organic residues were dissolved in 50 μl of Bis(trimethylsilyl)trifluoroacetamide-pyridine (4:1, v/v), incubated for 1 h at 60 °C, and then 1 μl was injected for cholesterol analysis in GC-MS. RNA Extraction and Gene Expression Analysis Total RNA was extracted from 3T3-L1 and ...
In contrast, if the dissociation constant is too small (<1 μM), meaning that the affinity between the protein and the ligand is strong, the protein will hold the ligand tightly, which restricts the release of the VOC to the cuticle and limits the overall mass transfer. Therefore, the ...
We surmised that the Ar-BIAN ligand can be functionalised with an electron-withdrawing anchoring functionality such as a carboxylate, with the dual function of facilitating grafting on the surface of metal oxides, and also enhancing the absorption profile. Herein, we describe the synthesis of the ...
Experimental results on 3d O<sub>h</sub> complexes in insulators reveal that 10Dq α R<sup>−n</sup>, where R is the metal–ligand distance and n is close to five. This strong dependence determines the Huang–Rhys factor, S(A<sub>1g</sub>), associated to the symmetric A<sub>1g...
It is remarkable for being a strong-field ligand, i.e. one that often creates low-spin complexes even for 3d-metals (which generally prefer high-spin if there are no competing reasons for low-spin). While one could draw analogies to COCO or even NO+NO+ whose π-antibonding orbitals are...
8b, e). Whereas no water molecule is found in a similar coordination in HIPK3 and DYRK1A, a weak hydrogen-bond could be formed by the methionine sulfur to the nitrogen in the linker between the aminopyrimidine and the pyridine compensating for the water-mediated interaction in Cdk6. Toward...
An investigation into the isomeric forms of nitrophthalic acids interacting with pyridine is presented in this study. This work involves a detailed exploration of the synthesized complexes, employing both experimental techniques (X-ray crystallography, infrared, and Raman spectroscopies) and computational ...
