The Impact of Glycation on Protein Digestibility

ChemFoodChem, EarlyView.
Schematic overview of how protein glycation affects digestibility and downstream nutritional consequences. Glycation‐derived structural modifications reduce protease accessibility, leading to limited hydrolysis and altered peptide generation. These changes decrease amino acid bioavailability and may subsequently contribute to microbiome alterations ...

Polyamines in aging and disease

, 2011
Polyamines are polycations that interact with negatively charged molecules such as DNA, RNA and proteins. They play multiple roles in cell growth, survival and proliferation. Changes in polyamine levels have been associated with aging and diseases. Their

One‐Shot Pd(II)‐Catalyzed Multiple C–H Activation Enables Modular Construction of Fluorenylidene Oxindole‐Based Multi(Polycyclic) Aromatic Enes

Chemistry – A European Journal, EarlyView.
A one‐shot Pd(II)‐catalyzed C─H activation strategy enables the rapid conversion of simple linear propiolamides into structurally diverse mono‐, di‐, and tri‐olefin‐bridged MPAEs. This cascade process orchestrates up to six sequential C–H activations in a single operation, providing streamlined access to highly conjugated architectures.

Polyamines: the pivotal amines in influencing the tumor microenvironment

Discover Oncology
Cellular proliferation, function and survival is reliant upon maintaining appropriate intracellular polyamine levels. Due to increased metabolic needs, cancer cells elevate their polyamine pools through coordinated metabolism and uptake.

Localized Prostate Cancer Therapy: Tumor Microenvironment‐Activated Spermine Hydrogel With Real‐Time Autonomous Fluorescence Sensing

Chemistry – A European Journal, EarlyView.
First tumor microenvironment (TME)‐responsive spermine‐loaded hydrogel with autonomous sensing for advanced local therapy of prostate cancer (PCa) is developed. Spermine can be released from the hydrogel to kill the prostate cancer cells specifically under acidic TME.

Polyamines as olfactory stimuli in goldfish [PDF]

, 2002
The effects of polyamines as odorants to goldfish olfactory receptors were investigated by in vivo electrophysiological recordings. Electro-olfactogram (EOG) recordings indicated that polyamines (putrescine, cadaverine and spermine) are potent olfactory ...

The influence of chemical polyamines analogs, decarboxylated ornithine and s-(adenosyl)-methionine on the polyamine synthsis velocity in test-systems from tissues with high proliferation

RUDN Journal of Medicine, 2010
The aliphatic (amino)- and (oxy)-derivatives of polyamines effect on the rate of polyamines (Putrescine, Spermidine and Spermine) synthesis in cell-free test-systems from rat's regenerating liver and Hepatoma tissues was examined.
