Pharmacological activity research
The pharmacological activity research of oxidized resveratrol glucoside mainly focuses on its anti-aging, antioxidant, anti-inflammatory, and cell protective effects.
Antioxidant effect
As a polyphenolic compound, oxidized resveratrol glucoside has significant free radical scavenging ability. In vitro studies have shown that it can effectively eliminate hydroxyl radicals, superoxide anions, and hydrogen peroxide, and reduce lipid peroxidation levels. By activating intracellular antioxidant enzyme systems such as SOD1, CAT, and HMOX1, the cell's resistance to oxidative stress is enhanced, and the process of cell damage and apoptosis is slowed down.

Oxidized resveratrol glucoside reduces inflammation by inhibiting the NF - κ B signaling pathway and downregulating the expression of pro-inflammatory factors such as TNF - α, IL-6, and IL-1 β. Its anti-inflammatory effect helps alleviate chronic inflammation, delay inflammation related tissue damage and functional decline.
Anti aging effect
Multiple cell and animal model studies have shown that oxidized resveratrol glucoside can prolong cell lifespan and improve aging related phenotypes. Its mechanism of action involves activating energy metabolism regulatory protein AMPK and deacetylase SIRT1, promoting mitochondrial function and cellular metabolic homeostasis. By upregulating the expression of telomerase reverse transcriptase TERT, we protect telomere integrity and delay cellular aging. Regulating the cyclin dependent kinase inhibitor CDKN1A, inhibiting abnormal cell cycle progression, and preventing premature cell aging.
Neuroprotective effect
Despite its low ability to penetrate the blood-brain barrier, oxidized resveratrol glucoside exhibits antioxidant and anti apoptotic effects in an in vitro neural cell model, reducing oxidative stress-induced neuronal damage and suggesting its protective potential for the nervous system through peripheral or indirect mechanisms.
Mechanism of action and molecular targets
The multi-target mechanism of action of oxidized resveratrol glucoside is the basis for its anti-aging and related pharmacological effects. The main targets and their mechanisms of action are as follows:
AMPK（5' AMP-activated protein kinase）
AMPK is a key regulatory factor in cellular energy metabolism, capable of sensing energy status and regulating metabolic balance. Oxidized resveratrol glucoside activates AMPK, promotes fatty acid oxidation and glycolysis, enhances mitochondrial biosynthesis, improves cellular energy supply, and delays metabolic aging.
SIRT1 (silencing information regulatory factor 2 related enzyme 1)
SIRT1 is an NAD+- dependent deacetylase involved in regulating gene expression, DNA repair, and metabolic homeostasis. Oxidative resveratrol glucoside activates SIRT1, promotes deacetylation, regulates various aging related proteins such as TP53 and FOXO1, and enhances cellular antioxidant and repair capabilities.
TERT (telomerase reverse transcriptase)
TERT is the catalytic subunit of telomerase, which maintains telomere length and prevents chromosome end degeneration. Oxidized resveratrol glucoside upregulates TERT expression, delays telomere shortening, protects cellular genetic stability, and prolongs cell lifespan.
TP53 (tumor suppressor protein p53)
TP53 plays a central role in cell cycle regulation and DNA damage response. Oxidized resveratrol glucoside regulates TP53 activity, balances cell proliferation and apoptosis, prevents abnormal cell accumulation, and maintains tissue homeostasis.
NRF2 (Nuclear Factor E2 Related Factor 2)
NRF2 is the main regulator of antioxidant reactions, promoting the expression of antioxidant enzyme genes. Oxidative resveratrol glucoside activates the NRF2 signaling pathway, enhances cellular antioxidant defense, and reduces oxidative damage.
SOD1, CAT, HMOX1 (antioxidant enzymes)
These enzymes directly participate in clearing reactive oxygen species (ROS) and maintaining cellular redox balance. Oxidized resveratrol glucoside upregulates its expression and activity, strengthening the cellular defense system.
FOXO1 (forkhead box protein O1)
FOXO1 regulates cellular stress response and metabolic gene expression. Oxidized resveratrol glucoside promotes cell survival and antioxidant gene expression by regulating FOXO1.
CDKN1A (cyclin dependent kinase inhibitor 1A)
CDKN1A regulates the cell cycle progression, preventing DNA damage and abnormal cell proliferation. Oxidized resveratrol glucoside regulates its expression, promotes cell cycle arrest, and prevents age-related cellular dysfunction.
In summary, oxidized resveratrol glucoside exhibits comprehensive anti-aging potential by synergistically regulating cell metabolism, antioxidant defense, gene stability, and cell cycle through multiple targets and pathways.
Evaluation of drug properties and pharmacokinetics
The pharmacological parameters of oxidized resveratrol glucoside show that it has good potential for drug development. The molecular weight is 406.3870, which falls within the molecular weight range of small molecule drugs. The LogP value of 0.3192 indicates moderate hydrophilicity, which is beneficial for in vivo distribution and dissolution. A higher TPSA (160.07) suggests limited cell membrane penetration ability, but improved bioavailability can be achieved through specific transport mechanisms or drug carrier systems.
Good water solubility (3.1706), convenient for formulation design and oral administration. The low penetration ability of the blood-brain barrier limits its direct application in central nervous system diseases, but reduces the risk of central neurotoxicity. HERG channel inhibition negative and Ames test negative indicate low risk of cardiac toxicity and genotoxicity, and high safety.
In terms of pharmacokinetics, existing research is relatively limited. Preliminary in vivo experiments have shown that oxidized resveratrol glucoside can be detected in plasma after oral administration, but its bioavailability is limited by intestinal enzymatic hydrolysis and first pass effects. Its glycoside structure may be hydrolyzed by gut microbiota into oxidized resveratrol, which has stronger biological activity and better tissue permeability.
