Cytotoxic Effects of Medicinal Plant Extracts on HeLa Cells via Redox Imbalance, L‐Arginine Metabolic Reprogramming, and Glycolytic Suppression

Cell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT Cancer cells undergo metabolic reprogramming to sustain proliferation, resist apoptosis, and adapt to oxidative stress. In the present study, we comparatively evaluated the anticancer effects of four medicinal plant extracts (Inula helenium, Hypericum alpestre, Rumex obtusifolius, and Alchemilla smirnovii) on HeLa cervical cancer cells, with ...

Hydrazone‐Type Ligands for Asymmetric Catalysis

ChemistryEurope, Volume 4, Issue 9, September 2026.
The introduction of trans 2,5‐disubstituted pyrrolidines is the key design element enabling the excellent stereocontrol exerted by hydrazone‐based N‐ligands in a variety of transition metal‐catalyzed transformations, including Diels–Alder cycloadditions, Suzuki/Hiyama/Negishi cross‐couplings, 1,2‐additions to a variety of imines and hydrazones, and ...

Exploiting the B–N/C–C Isosterism Yields Nile‐Red Inspired Organoboron Dyes Capable of Singlet‐Oxygen Photosensitization

ChemistryEurope, Volume 4, Issue 9, September 2026.
B─N bridged Nile Red derivatives: B─N/C─C isosterism enables a new class of Nile Red (NR) derivatives featuring a B─N linkage connecting both the western and eastern fragments of NR. The resulting NR‐inspired boronic acid‐derived salicylidenehydrazone (NR‐BASHY) complexes showcase promising photophysical properties, targeted bioimaging capability, and ...

Co‐Acid Free Nitration of N,N‐Dimethylanilines Using Traditional and Nontraditional Activation Methods

Chemistry–Methods, Volume 6, Issue 9, September 2026.
Selective mono‐ and dinitration of dimethylanilines by co‐acid‐free dilute aqueous nitric acid using nontraditional activation methods, such as microwave, ultrasound, and high hydrostatic pressure. The nitration of aromatic compounds is a highly important transformation, contributing to the synthesis of dyes, agrochemicals, explosives, pharmaceuticals,

Detection of Testosterone Esters in Urine: Evidence of Trace‐Level Detectability in Doping Control Samples

Drug Testing and Analysis, Volume 18, Issue 9, Page 1157-1162, September 2026.
An ultrasensitive LC‐MS/MS method for detecting testosterone esters (T‐esters) in urine at sub–pg/mL levels is presented. This approach, employing Girard P derivatization, provides the first evidence of T‐esters' trace‐level detectability in human urine.
