Glucose‐Responsive Modified Poly(Propylene Imine) Dendrimer for Self‐Regulated Insulin Delivery

Macromolecular Materials and Engineering, Volume 311, Issue 1, January 2026.
Poly(propylene imine) dendrimers functionalized with phenolboronic acid (PBA) are synthesized and modified to develop a glucose‐sensitive system with a pKa of ∼7.4. Also, the equilibrium binding constant (Keq‐tet) for PBA‐attached G4 dendrimer (HB‐CBA) was determined to be 79 m−1.

Analysis of Methylated Quaternary Ammonium Compounds Using Hydrophilic Interaction Liquid Chromatography Combined With Mass Spectrometry

Mass Spectrometry Reviews, Volume 45, Issue 1, Page 107-119, January/February 2026.
ABSTRACT Liquid chromatography‐mass spectrometry (LC–MS) is a powerful technique for the detection and quantification of methylated quaternary ammonium compounds (mQACs), such as acylcarnitines and methylated amino‐acid‐derived (betainized) compounds, in biological matrices.

Mass Spectrometry‐Based Applications in Tannin Analytics: From Qualitative and Quantitative Analyses to Biological Activity

Mass Spectrometry Reviews, Volume 45, Issue 1, Page 120-146, January/February 2026.
ABSTRACT Tannins are widespread specialized plant metabolites that contribute significantly to the polyphenol content of plant‐based diets. Their effects on human and animal health vary depending on their structure, with potential benefits including antioxidative, antimicrobial, anthelmintic, and anticarcinogenic properties.

Astatine‐211—Towards In Vivo Stable Astatine‐211 Labeled Radiopharmaceuticals and Their (Pre)Clinical Applications

Medicinal Research Reviews, Volume 46, Issue 1, Page 203-237, January 2026.
ABSTRACT Targeted radioligand therapy has emerged as a promising treatment option for eradicating advanced cancer forms. α‐Emitters are considered particularly promising as they can obliterate (micro)‐metastases. The α‐emitter astatine‐211 (211At) has experienced increased interest due to its favorable decay properties.

Paving the Way Toward New Push‐Pull Superbases in the Gas Phase by an Effective DFT Approach: The Case of a New Structurally Complex Molecule, 5‐Aminopyrrole‐2‐Amidine

Journal of Physical Organic Chemistry, Volume 39, Issue 1, January 2026.
DFT calculations, carried out in the gas phase for all possible tautomers of 5‐aminopyrrole‐2‐amidine (APA), permit the estimation of their relative stabilities and allow the selection of energetically favored forms. All tautomers are push‐pull imino N‐bases that exhibit calculated basicities in the higher range of the current gas‐phase basicity scale.
