Charge Regulation in Crowded Solutions of a Weak Polyelectrolyte: Steric Interactions

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 3, May 2026.
Weak polyelectrolytes (WPE) solvated in biorelevant media and synthetic complex fluids that contain substantial concentrations of macromolecules, molecular assemblies, and nanoparticles are observed to exhibit deviations from the acid–base equilibrium observed in single‐component solutions.

Uracil–Peptide–Pyrene Conjugates as Cu2+‐Sensitive Probes Targeting DNA, RNA, and Biorelevant Model Membranes

open access: yesChemBioChem, Volume 27, Issue 8, April 2026.
We introduce uracil–triazole–pyrene peptidomimetics whose tunable peptide linkers precisely control light emission, copper binding, and interactions with DNA and RNA. Fine structural adjustments unlock selective biomolecular recognition and striking metal‐ and membrane‐responsive fluorescence, paving the way for a new generation of multifunctional ...

Structure–Property Correlation of Diacylglycerol‐Modified Lipid Bases: Crystallization and Dispersion Behaviors

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
Medium‐chain diacylglycerols were incorporated into fully hydrogenated palm kernel oil stearin (FHPKS) to regulate crystallization behavior and melt–dispersion performance. Low DAG levels (5%–10%) promoted β′‐rich crystal networks and improved thermal responsiveness, establishing a structure–property framework for designing functional lipid bases ...

Impact of presence of excipients in drug analysis in fed-state gastric biorelevant media [PDF]

open access: yesEuropean Journal of Pharmaceutics and Biopharmaceutics, 2018
In this study, the influence of the presence of excipients in sample preparation and clean-up steps required prior to drug analysis in milk-based media which simulate the in vivo properties of the fed state stomach was investigated. 15 excipients, normally present in solid dosage forms of five APIs tested (atenolol, paracetamol, furosemide, nifedipine ...
