GC–MS analysis of oxysterols and their formation in cultivated liver cells (HepG2)

Lipids, Volume 58, Issue 1, Page 41-56, January 2023., 2023
Abstract Oxysterols play a key role in many (patho)physiological processes and they are potential biomarkers for oxidative stress in several diseases. Here we developed a rapid gas chromatographic‐mass spectrometry‐based method for the separation and quantification of 11 biologically relevant oxysterols bearing hydroxy, epoxy, and dihydroxy groups ...

Gas-liquid chromatography of dialkyl, alkyl acyl, and diacyl derivatives of glycerol

Journal of Lipid Research, 1969
Dialkyl, alkyl acyl, and diacyl glycerols were resolved as trimethylsilyl ethers and as acetates by gas-liquid chromatography on a nonpolar stationary phase (OV-1).

Iron‐Catalyzed [2+2+2] Cycloadditions for the Construction of Aromatic and Heteroaromatic Rings

Chemistry – A European Journal, EarlyView.
Iron catalysis has witnessed numerous applications during the last decades. This review is focused on the developments of iron complexes for the construction of aromatic and heteroaromatic rings by [2+2+2] cycloadditions. The importance of the design of the iron coordination sphere along with the use of several co‐catalysts is discussed, as well as the

Exploring Tyramine's Role in the Formation of Supramolecular Adducts with Nonsteroidal Anti‐Inflammatory Drugs

Chemistry – A European Journal, EarlyView.
An a priori design approach identified tyramine as an ideal co‐former for obtaining new supramolecular adducts with nonsteroidal anti‐inflammatory drugs, speeding up the co‐crystallization process. Three novel adducts and a new polymorphic form were synthesized and thoroughly characterized by solid‐state NMR and single‐crystal XRD.
