35Cl NMR of Metal‐Organic Frameworks: What Can We Learn?

Chemistry–Methods, EarlyView.
35Cl solid‐state NMR of MOFs offers insights into bonding mode and character, hydrogen bonding, phase transitions, and reaction products, even near paramagnetic centers. 35Cl NMR parameters reflect Cl coordination and local geometry. DFT methods accurately predict 35Cl NMR parameters. This 35Cl NMR/DFT approach is applicable to other MOFs and materials.

A Mechanochemical Route for the Synthesis of Diphenyleneiodonium Salts and the Estimation of Their Relative Solid‐State Reactivities

Chemistry–Methods, EarlyView.
An efficient mechanochemical route for diphenyleneiodonium (DPI) salt synthesis is reported which offers a sustainable and solvent‐free alternative. The solid‐state reactivities of the reported DPI salts were also assessed with the help of morphology predictions and Hirshfeld surface analysis computations to understand the effect of crystal morphology,

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Waxy‐ or Putty‐Like Materials as a Novel Drug Preparation for Synthetic Cannabinoid Receptor Agonists: Detection in Prisons and In Vitro Cannabinoid Receptor Activity

Drug Testing and Analysis, EarlyView.
Waxy‐ or putty‐like materials has emerged as a novel drug preparation for synthetic cannabinoids and other drugs in UK prisons. An in vitro CB1 bioassay was used to evaluate the CB1 activating potential of MDMB‐INACA and extracts from eight seized samples. MDMB‐INACA had moderate efficacy but low potency at CB1.

Identification and Investigation of the Intrinsic Receptor Activation Potential and Metabolization of the New Oxo‐Pyridyl Synthetic Cannabinoid Receptor Agonist CH‐FUBBMPDORA

Drug Testing and Analysis, EarlyView.
Another Chinese generic ban‐evading SCRA, CH‐FUBBMPDORA, has emerged. This study reports its first identification in Europe, its analytical characterization (NMR, Raman, FTIR, GC–MS, and HRMS), its cannabinoid activation potential in a βarr2 recruitment assay, and its metabolization profile.
