The Wonders of Vanilla: Celebrating the 150th Anniversary of Synthetic Vanillin

ChemFoodChem, EarlyView.
Xxxxxxx ABSTRACT The year 2024 marked the 150th anniversary of the first commercial production of vanillin, a milestone that revolutionized the global flavor and fragrance industry. In this review, the fascinating and uniquely rich history of vanilla is first highlighted, from its origins in the tropical forests of Mesoamerica, to its introduction to ...

Design of a Fluorescent Boronic Acid‐Functionalized Pyranoflavylium Receptor to Host and Release Diol‐Rich Bioactive Analytes in a pH‐Dependent Manner

ChemFoodChem, EarlyView.
This work presents a pH‐responsive ON–OFF fluorescent system based on a novel pyranoflavylium dye functionalized with a boronic acid receptor. The receptor exhibits a markedly higher affinity for the catechol‐containing polyphenol (+)‐catechin than for conventional diol‐rich molecules such as glucose and lactic acid.

An Experimental and Educational Framework for Nonenzymatic Polyphenol Conversion: Bridging Molecular Food Science and Materials Technology through Organic Chemistry

ChemFoodChem, EarlyView.
Gallic acid serves as an ideal bridge between fundamental sciences and gastronomy, as its presence as a plant polyphenol moiety. Its symmetrical, multifunctional phenolic structure makes it a perfect educational building block for linking organic chemistry both to food science and material design.

Stafib‐2‐CR: an Improved Nanomolar and Selective Inhibitor of the Transcription Factor STAT5b Developed by Conformational Restriction of Stafib‐2

Chemistry – A European Journal, EarlyView.
Conformational restriction strategies to increase the activity and selectivity of the STAT5b inhibitor Stafib‐2 are presented. The best conformationally restricted inhibitor Stafib‐2‐CR has threefold higher activity against STAT5b than Stafib‐2. A cell‐permeable prodrug of Stafib‐2‐CR inhibits phosphorylation of STAT5b in cultured human leukemia cells ...

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Carbon Dots for Cancer Theranostics: Synthesis Strategies, Luminescence Properties, and Advances in Bioimaging‐Guided Diagnosis and Therapy

Chemistry – A European Journal, EarlyView.
Lighting up the path to precision oncology: This review comprehensively summarizes the rational design of carbon dots (CDs), elucidating how core size, surface chemistry, and heteroatom doping dictate their luminescence mechanisms. Special emphasis is placed on engineering NIR‐II emissive CDs for deep‐tissue imaging.
