Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Repeated Intake of Grapefruit Juice Inhibits CYP2B6, CYP2C9, CYP2C19, and CYP3A4 while Lingonberry Powder Does Not Induce Major CYP Enzymes in Humans

Clinical Pharmacology &Therapeutics, EarlyView.
Grapefruit juice is a well‐established inhibitor of cytochrome P450 (CYP) 3A4, but its effects on other CYP enzymes or organic anion transporting polypeptides (OATPs) are not fully characterized in humans. Recently, lingonberry powder was shown to induce murine CYP enzymes. We investigated the effects of lingonberry powder and grapefruit juice on seven

Untargeted Metabolomics Identifies N‐Lactoyl‐Amino Acids as Dose‐Responsive Plasma Biomarkers of Metformin Adherence in Type 2 Diabetes

Clinical Pharmacology &Therapeutics, EarlyView.
Metformin is the most widely prescribed antidiabetic drug, yet adherence remains difficult to objectively assess. Using untargeted metabolomics and lipidomics, we analyzed plasma from 637 patients with type 2 diabetes (T2D) with confirmed metformin use and 143 nondiabetic controls, annotating 614 metabolites.

Rapid Identification of New Psychoactive Substances in Letters by LA‐APCI‐MS

Drug Testing and Analysis, EarlyView.
Laser ablation coupled to molecular mass spectrometry utilizing a modified atmospheric pressure chemical ionization source was used for the detection of synthetic cannabinoid receptor agonists in infused prison mail samples. ABSTRACT New psychoactive substances (NPS), especially synthetic cannabinoid receptor agonists (SCRA), are increasingly smuggled ...
