Lipidomic analysis and classification of Iberian dry‐cured hams with low field NMR

Food Frontiers, 2023
Iberian ham is a high‐quality food that is traditionally produced from black pigs that are native to the Iberian Peninsula. The taste and texture of Iberian ham are largely determined by its lipid content and composition.

Chemotherapeutic Potential of Fluorouracil‐Platinum (IV) Prodrugs Against Cisplatin‐Resistant Colorectal Cancer Cells

Chemistry – A European Journal, EarlyView.
ABSTRACT Fluorouracil‐platinum(IV) prodrugs represent a novel class of multimechanistic chemotherapeutics with enhanced anticancer potential. The prodrugs PtIVP‐5FUMeOBut and PtIV56‐5FUMeOBut were actualized by derivatising the clinical drug 5‐fluorouracil (5FU) and coordinating it to platinum(IV) complexes, leveraging the established cytotoxicity of ...

In situ reaction monitoring in heterogeneous catalysts by a benchtop NMR spectrometer [PDF]

Magnetic Resonance Imaging, 2019
Understanding the reactivity and mass transport properties of porous heterogenous catalysts is important for the development of new materials. Whereas MRI has previously been used to correlate chemical kinetics and hydrodynamics under operando conditions, this paper demonstrates that a modern benchtop NMR spectrometer is a suitable alternative to ...

Neue Versuche mit Spiropyran: Photometrie, NMR‐Spektroskopie und On‐Water‐Synthese

CHEMKON, EarlyView.
Reaktionskinetik wird häufig als schwierig, theoretisch und Mathematik‐lastig empfunden, weshalb experimentelle Zugänge für diesem Themenbereich notwendig sind. In diesem Beitrag werden entsprechende Versuche zur Reaktionskinetik vorgestellt, bei denen das Farbstoffsystem eines Spiropyrans und dessen isomerer Merocyanin‐Form untersucht wird.

Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Layer Geometry Modulation in Cu(II) Coordination Networks Based on Disubstituted Bis(imidazolyl)benzene Ligands

European Journal of Inorganic Chemistry, EarlyView.
Cu(II)‐based two‐dimensional coordination networks constructed from bis(imidazolyl)benzene ligands show how subtle changes in counteranion identity modulate layer geometry, stacking, and stability. Single‐crystal structures combined with bulk syntheses reveal distinct packing efficiencies and framework responses to humidity, vacuum, and temperature for

AI‐Driven Synthesis in Medicinal Chemistry: Integrating Large Language Models, Robotic Automation, and Sustainability Metrics to Accelerate Drug Discovery

Medicinal Research Reviews, EarlyView.
ABSTRACT Artificial intelligence (AI) is transforming synthetic chemistry from task‐specific predictors into integrated platforms that unify retrosynthesis, reaction optimization, and closed‐loop robotic automation. This review highlights how AI‐assisted planning and robotic execution shorten cycle times, reduce step counts, and improve route ...
