Since its discovery in the bacterium Chromobacterium violaceum, violacein-a striking purple pigment-has garnered significant interest due to its promising applications in the food and pharmaceutical industries. Violacein exhibits a range of pharmacological properties, including anti-inflammatory, anticancer, antibacterial, and antiparasitic effects, yet its complete molecular mechanisms are still being elucidated. Its mechanisms of action likely involve complex interactions with cellular receptors, signaling pathways, and specific molecular targets. Given violacein's unique properties and bioactive intermediates, future research holds substantial potential to advance its clinical and industrial applications. Upcoming studies will focus on deepening our understanding of violacein's molecular interactions, conducting clinical trials, and refining drug delivery systems to maximize its therapeutic value. Additionally, obtaining regulatory approval, conducting rigorous safety assessments, and developing efficient biosynthetic methods remain essential steps for violacein's successful integration into food biotechnology and medical applications.

Atherosclerosis (AS) is increasingly recognized as a disease influenced not only by lipid metabolism and inflammation but also by the gut microbiota and their bioactive metabolites. Isoquercitrin (ISO), a natural flavonoid with food-medicine homology, has shown promising antiatherosclerotic potential, yet its underlying mechanisms remain unclear. In this study, ISO administration significantly reduced plaque burden, improved lipid profiles, and restored gut microbial balance by enriching beneficial taxa, such as , , and .

Epigallocatechin-3-gallate (EGCG), the main catechin in green tea, is associated with antidiabetic and anti-obesity effects, although its acute hepatic actions remain unclear. We investigated short-term effects of EGCG (10-500 μm) using isolated perfused rat livers and complementary assays in mitochondrial, microsomal, and cytosolic fractions. EGCG markedly inhibited gluconeogenesis from lactate (up to 52%), glycerol (33%), and alanine (47%), while it stimulated glycolysis, glycogenolysis, and oleic acid oxidation (+42% total ketone bodies).

Background: Traditional Chinese medicines (TCMs) have a long-standing history and diverse applications. However, their complex multi-component compositions and intricate mechanisms of action pose significant challenges for modern scientific investigation. Addressing these complexities requires advanced techniques capable of dissecting cellular and molecular interactions with high resolution.
