Special Issue Information

Dear Colleagues,

Resveratrol, a polyphenolic stilbene found in grapes, berries, and Polygonum cuspidatum, continues to engage scholarly interest due to its broad pharmacological profile and therapeutic promise across a range of chronic and degenerative diseases. This Special Issue will consolidate current knowledge on the molecular mechanisms underlying resveratrol’s bioactivity and highlight innovative approaches that could unlock its full clinical potential.

Extensive preclinical evidence supports resveratrol’s modulatory effects on critical signaling pathways, including SIRT1 activation, AMPK signaling, NF-κB inhibition, and oxidative stress reduction. These molecular interactions underpin its antioxidant, anti-inflammatory, neuroprotective, cardioprotective, and anticancer properties. Notably, resveratrol’s ability to influence mitochondrial biogenesis and cellular senescence pathways has renewed interest in its applications in age-related diseases and longevity research. However, despite compelling in vitro data, the compound’s low bioavailability and rapid metabolism pose persistent challenges to clinical translation. As such, there is a growing need to complement in vitro insights with investigations conducted in physiologically relevant in vivo systems, which provide a more comprehensive understanding of resveratrol’s pharmacokinetics, therapeutic efficacy, and safety in a biological context.

By assembling original research articles, mechanistic studies, and translational reviews, this issue will catalyze a shift toward more physiologically relevant models in the study of natural compounds. Resveratrol serves not only as a promising therapeutic candidate but also as a case study of how modern research tools can reshape our understanding of natural compound pharmacology.

Pulmonary drug delivery represents a promising approach in the treatment of respiratory diseases, allowing for passive targeting and enhanced drug efficacy. Background/Objectives: The aim of the present study was to develop inhalable dry powders from lyophilized sildenafil citrate (SC)-loaded liposomes made from phosphatidylcholine and either cholesterol (CH) or resveratrol (RSV). Methods: Liposomes were prepared via a pH gradient method to increase drug entrapment efficiency and drug loading, and then the liposomes were lyophilized using different proportions of ethanol, mannitol, and lactose as excipients. The resulting dry cakes were converted into powders and evaluated for aerodynamic performance using a custom-designed air-blowing device. Notably, this is the first time that resveratrol has been used as a substitute for cholesterol in SC-loaded liposomes. Results: Our results demonstrate that RSV is a suitable liposome bilayer component and improves drug loading. Our findings prove that lyophilized cakes containing liposomes produce a dry powder that is suitable for aerosolization with potential application to pulmonary delivery of sildenafil citrate. The results suggest that RSV represents a potential alternative to traditional cholesterol-based liposomal formulations. Conclusions: This work presents a novel strategy for the pulmonary delivery of sildenafil, using biocompatible and FDA-approved mannitol and lactose for this administration route. Full article
