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

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 ...

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]
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 ...

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
