Inflammaging and Immunosenescence in the Post‐COVID Era: Small Molecules, Big Challenges

open access: yesChemMedChem, Volume 20, Issue 6, March 15, 2025.
The post‐COVID syndromes are strictly dependent from inflammaging and immunosenescence, for which the available treatments, particularly immunotherapy, have limited impact and safety issues. Alternative targets are under validation to disclose, besides anti‐inflammatory drugs, new small molecular entities able to counteract the imbalance of ...

Subunit rotation in a single FoF1-ATP synthase in a living bacterium monitored by FRET [PDF]

open access: yes, 2011
FoF1-ATP synthase is the ubiquitous membrane-bound enzyme in mitochondria, chloroplasts and bacteria which provides the 'chemical energy currency' adenosine triphosphate (ATP) for cellular processes. In Escherichia coli ATP synthesis is driven by a proton motive force (PMF) comprising a proton concentration difference {\Delta}pH plus an electric ...

Hybrid Molecules as Efficient Drugs against Multidrug‐Resistant Malaria Parasites

open access: yesChemMedChem, EarlyView.
Among hybrid molecules currently developed as antimalarial drug candidates, emoquine‐1 exhibits high activity against all the multidrug‐resistant Plasmodium strains tested up to now, including artemisinin‐resistant quiescent parasites, critical parameters for promising antimalarial drugs. It is also curative in mouse malaria.

Fast ATP-dependent Subunit Rotation in Reconstituted FoF1-ATP Synthase Trapped in Solution [PDF]

open access: yesarXiv, 2021
FoF1-ATP synthases are ubiquitous membrane-bound, rotary motor enzymes that can catalyze ATP synthesis and hydrolysis. Their enzyme kinetics are controlled by internal subunit rotation, by substrate and product concentrations, by mechanical inhibitory mechanisms, but also by the electrochemical potential of protons across the membrane.

Sustainable and Scalable Enzymatic Production, Structural Elucidation, And Biological Evaluation of Novel Phlorizin Analogues

open access: yesChemSusChem, Volume 18, Issue 8, April 14, 2025.
New α‐glycosides of chalcones and dihydrochalcones, analogues of naturally occurring phlorizin, have been synthesized using a CGTase‐catalyzed glycosylation that was successfully scaled‐up in a 10‐liter reactor. The α‐glycosides were (i) purified using an original centrifugal partition chromatography technique, (ii) characterized through NMR and LC–MS ...

In silico identification of Capsicum type III polyketide synthase genes and expression patterns in Capsicum annuum

open access: yesOpen Life Sciences, 2020
Studies have shown that abundant and various flavonoids accumulate in chili pepper (Capsicum), but there are few reports on the genes that govern chili pepper flavonoid biosynthesis. Here, we report the comprehensive identification of genes encoding type

Detecting substeps in the rotary motors of FoF1-ATP synthase by Hidden Markov Models [PDF]

open access: yes, 2007
FoF1-ATP synthase is the enzyme that provides the 'chemical energy currency' adenosine triphosphate, ATP, for living cells. The formation of ATP is accomplished by a stepwise internal rotation of subunits within the enzyme. We monitor subunit rotation by a single-molecule fluorescence resonance energy transfer (FRET) approach using two fluorophores ...

How Does Nature Create the Painting “Gradient Coloration of ‘Manicure Finger’ Grape”? Integrated Omics Unveil the Pigments Basis and Metabolism Networks of Its Formation

open access: yesFood Frontiers, Volume 6, Issue 2, Page 921-939, March 2025.
Based on integrated omics, the metabolic regulation networks underlying gradient coloration of ‘Manicure Finger’ grape were constructed at three levels of color‐presenting substances, structural genes, and transcription factors. ABSTRACT ‘Manicure Finger’ grape exhibits gradient coloration during veraison, where the lower part of the skin changes color

Anthocyanins Profiling Analysis and RNA-Seq Revealed the Dominating Pigments and Coloring Mechanism in Cyclamen Flowers

open access: yesBiology, 2022
Pigments in cyclamen (Cyclamen purpurascens) endows flowers with great ornamental and medicinal values. However, little is known about the biosynthetic pathways of pigments, especially anthocyanins, in cyclamen flowers. Herein, anthocyanins profiling and
