Malvidin-3-O-glucoside chloride 是一种主要的葡萄酒花青素,能够调节大脑突触可塑性和外周炎症,促进应激反应的发生。
产品描述
Malvidin-3-O-glucoside chloride has antioxidant activity, alone is not oxidized in the presence of grape polyphenol oxidase. Malvidin-3-O-glucoside chloride's color stabilization at a higher pH can be explained by self-aggregation of the flavylium cation and copigmentation with the Z-chalcone form.
体外活性
Here we used a gel electrophoresis assay employing supercoiled DNA plasmid to examine the ability of these compounds (1) to intercalate DNA, (2) to inhibit human topoisomerase I through both inhibition of plasmid relaxation activity (catalytic inhibition) and stabilization of the cleavable DNA-topoisomerase complex (poisoning), and (3) to inhibit or enhance oxidative single-strand DNA nicking. We found no evidence of DNA intercalation by anthocyan(id)ins in the physiological pH range for any of the compounds used in this study-cyanidin chloride, cyanidin 3-O-glucoside, cyanidin 3,5-O-diglucoside, Malvidin-3-O-glucoside chloride and luteolinidin chloride. The anthocyanins inhibited topoisomerase relaxation activity only at high concentrations (>50 muM) and we could find no evidence of topoisomerase I cleavable complex stabilization by these compounds.
