δ-Viniferin is a COX-1/COX-2 inhibitor (with an IC₅₀ of 5 µM for both enzymes). δ-Viniferin induces the expression of SIRT1, catalase and HO-1, promotes the phosphorylation of eNOS, and stimulates nitric oxide (NO) production. δ-Viniferin is applicable to research related to atherosclerosis, downy mildew, Gram-positive bacterial infections, inflammation, infections, cardiovascular diseases and diabetes.

Vitis vinifera polysaccharide is a polysaccharide derived from Vitis vinifera.

Procyanidin B1 3'-O-gallate is a dimeric procyanidin.Procyanidin B1 3'-O-gallate can be found in the seeds of Vitis vinifera cv. Fernao Pires.

D-Glucoheptose is a heptose monosaccharide that serves as a starting material for sedoheptulose. D-Glucoheptose has a strong association with the genus Symbiobacterium. The content of D-Glucoheptose in urine of the control group without liver injury is higher than that in the anti-tuberculosis drug-induced liver injury group. D-Glucoheptose can be used in studies related to anti-tuberculosis drug-induced liver injury.

Guaiacol rutinoside (compound GuRG) is a guaiacol glycoconjugate (rutinoside form) that can be found in the fruit, leaves, and shoots of Vitis vinifera cv. Monastrell.

Mulberroside E is a natural phenolic compound.

Phenethyl acetate (Standard) is the analytical standard of Phenethyl acetate. This product is intended for research and analytical applications. Phenethyl acetate (Phenethyl alcohol, acetate) is an aryl alkyl alcohol simple acid ester found in evergreen trees and cloves. Phenethyl acetate can induce skin and eye irritation.

Malvidin-3-glucoside (Malvidin-3-O-glucoside; Oenin) chloride (Standard) is the analytical standard of Malvidin-3-glucoside chloride (HY-125740). This product is intended for research and analytical applications. Malvidin-3-glucoside 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.

Malvidin (chloride) (Standard) is the analytical standard of Malvidin (chloride). This product is intended for research and analytical applications. Malvidin (chloride) is a bioactive compound isolated from grape. Malvidin shows cytotoxicity through the arrest of the G2/M phase of cell cycle and induction of apoptosis.
