Peonidin 3-O-glucoside chloride is an agonist of the free fatty acid receptor FFAR1 and Glucokinase. Peonidin 3-O-glucoside chloride enhances insulin secretion of pancreatic beta cells and increases glucose uptake by liver cells. Peonidin 3-O-glucoside chloride activates FFAR1, promotes the phosphorylation of related proteins in the insulin secretion pathway, and increases the expression of FFAR1. In liver cells, Peonidin 3-O-glucoside chloride activates GK and regulates proteins associated with carbohydrate metabolism. Peonidin 3-O-glucoside chloride can be used in diabetes research.

Malvidin-3-glucoside (Malvidin-3-O-glucoside; Oenin) chloride is an orally active inhibitor of the NF-κB pathway, which blocks inflammatory responses induced by TNF-α, reduces IκB-α degradation and p65 nuclear translocation, and upregulates endothelial nitric oxide synthase eNOS to increase NO production. Malvidin-3-glucoside chloride exerts anti-inflammatory and antioxidant effects by inhibiting pro-inflammatory molecules such as MCP-1, ICAM-1, and IL-6, and regulating intestinal microorganisms and metabolites, while protecting endothelial cells and improving intestinal microecological dysbiosis under inflammatory conditions. Malvidin-3-glucoside chloride can be used to study chronic inflammatory-related diseases such as atherosclerosis and inflammatory bowel disease, and has the potential to prevent vascular inflammation and improve intestinal health.

Grape seed extract is a natural product, with anti-inflammatory and anti-proliferative effects. Grape seed extract shows inhibitory activity on the fat-metabolizing enzymes pancreatic lipase and lipoprotein lipase. Grape seed extract induces apoptotic in human colorectal cancer cells.

Astringin (trans-Astringin) is an orally active natural phenolic stilbene glucoside. Astringin can inhibit the production of oxidative stress, inflammatory factors, etc. Astringin has multiple activities such as anti-oxidation, anti-inflammation, and anti-apoptosis. Astringin is also an inhibitor of ferroptosis. Astringin can be used in the research of diseases such as acute lung injury.

Ethyl 3-hydroxybutyrate is a fragrance found in wine and Tribolium castaneum.

(E)-2-Octenal is an Antifungal agent. (E)-2-Octenal disrupts cell membrane integrity and causes ROS accumulation. (E)-2-Octenal decreases the activities of phosphofructokinase and pyruvate kinase.
