Pharmacokinetic Evaluation of a Cinnamon Product on CYP2A6 Substrate Drugs: Application of a Novel Tool Involving the Nicotine Metabolite Ratio

Clinical Pharmacology &Therapeutics, EarlyView.
Cinnamon (Cinnamomum spp.) is used as a culinary spice and dietary supplement. A major constituent, cinnamaldehyde, was previously shown to inactivate cytochrome P450 (CYP) 2A6 in vitro. A mechanistic static model predicted an ~5‐fold increase in the AUC of the CYP2A6 substrates nicotine and letrozole.

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

Contributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Identification and Structural Elucidation of a New Synthetic Cannabinoid, MDMB‐5′Br‐PINACA, in Seized Herbal Materials

Drug Testing and Analysis, EarlyView.
MDMB‐5Br‐PINACA, a novel synthetic cannabinoid, was identified and structurally characterized in seized herbal products using GC‐MS, LC‐HRMS, and NMR. The discovery underscores ongoing diversification of SCs and the need for vigilant surveillance.

Investigations Into the Human Metabolism of Trestolone (7α‐Methyl‐19‐Nortestosterone)

Drug Testing and Analysis, EarlyView.
As the known metabolites of 7α‐methyl‐19‐nortestosterone (MENT), M1 and M2, suffer from chromatographic issues under routine doping control conditions, the human metabolism of MENT was reinvestigated. From the numerous new metabolites detected, especially, M5 and M10 were identified as the most promising candidates to be implemented into routine ...
