Polyphenols are the main active components in Vitis amurensis Rupr. wine, which show good protective effects on the nervous system, but their compositions in Vitis amurensis Rupr. wine and the mol. mechanism underlying their neuroprotection remains unclear. The purpose of this study is to investigate the potential mechanism of the neuroprotective effect of Vitis amurensis Rupr. wine polyphenols on the basis of the specific composition of polyphenols in Vitis amurensis Rupr. wine. In this study, 40 phenolic compounds which include 15 anthocyanins, 10 flavonoids, 10 phenolic acids, 3 proanthocyanidins and 2 resveratrols were identified by UPLC Q-Exactive Orbitrap MS. Furthermore, An UPLC-QqQ/MS method was established to simultaneously determine the phenolic compounds in Vitis amurensis Rupr. Wine, and analyze the content differences of phenolic compounds between Vitis amurensis Rupr. and Vitis vinifera wine. Finally, network pharmacol. was employed for the first time to predict the possible pharmacol. mechanisms of Vitis amurensis wine polyphenols against nervous damage. Multivariate network anal. indicated that quercetin, (-)-epigallocatechin and various anthocyanins were found as prominent compounds for the treatment of nervous system diseases. Vitis amurensis Rupr. wine polyphenols mainly acted on these key targets, including AKT1, EGFR, ESR1, and SRC, and further regulate the PI3K-AKT and Rap1 signaling pathway for treating nervous system diseases. Our findings suggested that polyphenols in Vitis amurensis Rupr. wine possess neuroprotective effect through multicomponent, multitarget, and multichannel. Practical applications : Studies have revealed that Vitis amurensis Rupr. has higher levels of phenolic compounds than Vitis vinifera wine. However, due to the few and limited study of Vitis amurensis Rupr., their compositions in Vitis amurensis Rupr. wine and the mol. mechanism underlying their neuroprotection remains unclear. This research uses a holistic network pharmacol. strategy to investigate the potential targets and pharmacol. mechanisms of Vitis amurensis Rupr. wine polyphenols against nervous damage. To some things up, The finding elucidates the relationships between signaling pathways, targets, and compounds in Vitis amurensis Rupr. wine polyphenols, which may provide guidance and foundations for further application of medicinal food. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Quality Control of (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol).
(2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Quality Control of (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol
