CAS NO.501-36-0
High quality 501-36-0 lowest price Resveratrol supplier in China
resveratrol is a natural antioxidant, can reduce blood viscosity, inhibit platelet aggregation and vasodilation, maintain blood flow, can prevent the occurrence and development of cancer, has anti-atherosclerosis and coronary heart disease, ischemic heart disease, prevention and treatment of hyperlipidemia. Inhibition of tumor also has estrogen-like effect, can be used for the treatment of breast cancer and other diseases. Can delay aging, prevent cancer, in the red grape skin, red wine and grape juice in high content. Studies have shown that the integrity of the chromosome will be destroyed with the aging of human beings, and resveratrol can activate a protein sirtuin to repair the health of the chromosome, thus playing a role in delaying aging.
resveratrol is an inhibitor of many aromatic carcinogens, and is rated as a natural chemical preventive agent for heart and cerebrovascular diseases and cancer. A large number of studies have shown that resveratrol also has the functions of anti-mutation activity, protecting the cytotoxic effect induced by oxidized lipoprotein, and inhibiting the reproduction of tumor cells.
In 1940, humans isolated resveratrol from the roots of veratrum Veratrum grandiflorum for the first time. At present, it has been found in at least 72 species of plants in 21 families and 31 genera, such as Vitis in the Vitis family, Snake Vitis, Peanut, Cassia, Sophora, Polygonaceae, etc. Because the content of resveratrol in plants is very low and the extraction cost is high, the use of chemical, biological, genetic engineering and other methods to prepare resveratrol has become an indispensable means in its development process. The roadmap for the artificial synthesis of resveratrol is as follows:
3, 5-dihydroxybenzoic acid (3) is esterified to generate the corresponding 3, 5-dihydroxyphenyl methyl ester (4), and methyl ether is selected as the phenolic hydroxyl protecting group, so (4) is reacted with dimethyl sulfate to obtain methyl 3, 5-dimethoxybenzoate (5), and the corresponding benzyl alcohol (6) is generated after reduction, and further bromination to obtain 3, 5-dimethoxybenzyl bromide (7), and then through Abzoff reaction to prepare diethyl (3, 5-dimethoxybenzyl) phosphonate (8), and it and p-methoxybenzaldehyde After Wittig-Honer reaction to obtain the key intermediate 3,4, 5-trimethoxytrans stilbene (9), and finally demethylate with freshly prepared aluminum iodide, and separated by preparation thin layer chromatography to obtain the target resveratrol.
