resveratrol - Toxic activity

Open Data Unverified Data

resveratrol's hormonal and genotoxic activity: experiments have shown that resveratrol-induced cytotoxicity, micronucleus and metaphase chromosome translocation can be observed in L5178Y mouse lymphoma. Micronucleus induction was also observed in Chinese hamster V79 cells. Centromere signaling of the micronuclei and cell cycle analysis suggest that resveratrol does not directly disrupt tubulin polymerization released by mitotic cells. Studies have shown that resveratrol has no direct effect on microtubule assembly.
mechanism of protecting mitochondrial function: some scholars have studied the isolation of mitochondria in rat brain tissue through the rat model of hypoxia-reoxygenation, it was found that resveratrol completely blocked the release of cytochrome C in a concentration-dependent manner, and significantly reduced the formation of oxide anions at the concentration of 1nmol. The mitochondrial protective membrane damage caused by hypoxia-reoxygenation is approximately 0.1 protected at a concentration of 70% micromolar of resveratrol. In the presence of NADH and cytochrome C, a low 50% effective concentration of 18.34PM of resveratrol can block the oxygen consumption of mitochondria.
three mechanisms of resveratrol protecting mitochondria: antioxidant properties, the role of complex III and cell membrane stabilization.
peripheral anti-pain effect: the results of the 1% formalin test showed that resveratrol opened large and small conductance Ca2 + activated potassium ion channels, instead of the ATP-sensitive K + channel, it produced an anti-pain effect in the experiment, proving that the anti-pain effect of resveratrol is related to the K + channel. Voltage-dependent K + channels may also be involved.

Anticancer effect

both trans-resveratrol and cis-resveratrol have anti-cancer activity because they inhibit the activity of protein-tyrosine kinases. Resveratrol has high anti-cancer activity in the three stages of cancer initiation, promotion and development, and has inhibitory and even reversing effects on the three stages of cancer occurrence: first, inhibition of the initial effect. Reduce the formation of free radicals, induce the increase of the second phase of the drug, and antagonize the effect of dioxin; Second, inhibit the promotion. Inhibition of cyclooxygenase (COX ), inhibition of catalase; Three inhibitory effects on development. Inhibit cancer cell proliferation, induce cancer cell differentiation, induce cancer cell apoptosis. Resveratrol is expected to be an inhibitor of PTK. Many medical studies have found that resveratrol has obvious inhibitory effect on breast cancer, gastric cancer, colon cancer, prostate cancer, leukemia, ovarian cancer, skin cancer and other malignant tumor cells.

Antioxidant effect

resveratrol is a natural antioxidant existing in plants. It plays an antioxidant role mainly by scavenging or inhibiting free radical generation, inhibiting lipid peroxidation, regulating antioxidant related enzyme activity and other mechanisms. When the concentration of resveratrol was 1.3 μg /mL, it could obviously inhibit the auto-oxidative hemolysis of rat red blood cells and the oxidative hemolysis caused by H2O2, the production of lipid peroxides in the kidney was significantly inhibited in vitro and in vivo. The pharmacological functions of resveratrol such as antioxidation, inducing free radicals and affecting the metabolism of arachidonic acid have aroused widespread interest, because these physiological metabolism are involved in many physiological diseases closely related to human health, such as atherosclerosis, Alzheimer's disease, viral hepatitis, gastric ulcer, inflammation and allergic reactions.

Antibacterial effect

resveratrol has inhibitory effect on Staphylococcus aureus, catarrhal bacteria, Escherichia coli, Pseudomonas aeruginosa, and on orphans Virus, Herpes Sinplex Virus Virus and intestinal Virus and Coxsackie A, B group had a strong inhibitory effect. Resveratrol by reducing platelet adhesion, in the anti-inflammatory process to change the activity of platelets to achieve anti-inflammatory.

Lipid-lowering effect

because resveratrol has anti-cancer, antioxidant, anti-inflammatory, anti-bacterial effects and love people's love, plant sources said because the French people often drink high fat containing resveratrol, so the French people of coronary heart disease by the end Incidence Rate in other Western countries, from this information can be learned because of resveratrol effectively suppress the prevention and treatment of high fat.

Prevention of food allergy

in some people, the body's immune system causes an allergic reaction to foods such as eggs, wheat and milk, which in severe cases can lead to Shock deaths. Japanese researchers have found in animal experiments that resveratrol, which is rich in red wine, can prevent this food allergy.

Anti-oxidative stress effect of resveratrol

oxidative stress plays an important role in the development of diabetic nephropathy, and a variety of antioxidants can delay the development of DN. Resveratrol can protect against oxidative stress, thereby improving the symptoms of early DN. Resveratrol has obvious anti-oxidative stress effect, can avoid high glucose, high fat induced oxidative stress injury, which plays an important role in the prevention and treatment of diabetes and its chronic complications, especially in the early stage of diabetes delay the development of DN, protect the kidney tissue. However, although resveratrol is a natural drug with great potential, the related research is limited to animal experiments and cellular and molecular levels, and its clinical application is relatively small.
