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

open access: yesChemistry – 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 ...

Evaluation of Therapeutic Opioids in Skin‐Derived Matrices (Sweat and Sebum) of Neonatal and Pediatric Patients and Their Role in Opioid Incorporation Into Hair

open access: yesDrug Testing and Analysis, EarlyView.
Concentration ranges, dose–concentration relationships, and metabolite‐to‐parent drug ratios of therapeutic opioids were evaluated in hair and skin swab samples of 150 pediatric patients. Skin‐derived matrices such as sweat or sebum were shown to contribute to analyte incorporation into hair in a systematic manner.

Ethyl Glucuronide in Hair: A 10‐Year Overview

open access: yesDrug Testing and Analysis, EarlyView.
The present study builds on a unique collection of more than 68,000 hair EtG results collected in the Northen Italy between 2013 and 2022. We investigated trends in alcohol consumption in terms of age, gender, recidivism, applicants, sampling region, sampling length, across seasons, and the COVID‐19.

Neural Network‐Based Detection of Adulterants in Opioid Samples Using IR Absorption Spectroscopy

open access: yesDrug Testing and Analysis, EarlyView.
We construct a neural network for the classification of bromazolam and fluorofentanyl in illicit opioid samples. The model outperforms a random forest classifier and shows elevated performance for low concentration samples. ABSTRACT Community‐based drug checking services are challenged in their ability to reliably detect low concentration adulterants ...

High‐Adhesion Quadruple Hydrogen‐Bonded Ionogels: A Dual‐Function Platform for Gesture Recognition and Real‐Time NH3 Detection in Multiscenario

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Quadruple hydrogen‐bonded high‐adhesion ionogels for gesture recognition and real‐time NH3 sensing. Ionogels have garnered significant attention in flexible sensing due to their outstanding mechanical properties, conductivity, and stability. However, establishing a robust and stable adhesive interface with various substrates remains a significant ...
