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 ...

Activation and inhibition of sirtuins: From bench to bedside

open access: yesMedicinal Research Reviews, Volume 45, Issue 2, Page 484-560, March 2025.
Abstract The sirtuin family comprises seven NAD+‐dependent enzymes which catalyze protein lysine deacylation and mono ADP‐ribosylation. Sirtuins act as central regulators of genomic stability and gene expression and control key processes, including energetic metabolism, cell cycle, differentiation, apoptosis, and aging.
