MDN99781

MDN99781, also known as 2-O-α-D-Glucopyranosyl-L-ascorbic acid is a glucosylated derivative of L-ascorbic acid that has antioxidant and radioprotective activities. It scavenges 2,2-diphenyl-1-picrylhydrazyl radicals in a cell-free assay. AA-2G inhibits γ-radiation-induced cell death in CHO-10B2 and radiosensitive xrs5 cells, as well as UVC- or broadband UVB-induced cell death in CHO-10B2 and UV-sensitive UV135 cells. It is hydrolyzed to ascorbic acid by α-glucosidase and increases serum levels of ascorbic acid in rats and guinea pigs when administered orally at doses of 19.2 and 96 mg/animal, respectively. AA-2G reverses weight loss and inhibits subcutaneous hemorrhage in guinea pigs fed a vitamin C-deficient diet. This product has no formal name at the moment. For the convenience of communication, a temporary code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).
