In Vitro Antioxidant Activity of Two 6-(propan-2-yl)-4-methyl-morpholine-2,5-diones.
In vitro antioxidant activity of two cyclodidepsipeptides, 3-(2-methylpropyl)-6-(propan-2-yl)-4-methyl-morpholine-2,5-dione and 3,6-di(propan-2-yl)-4-methyl-morpholine-2,5-dione, was investigated. Our data indicate moderate antioxidant potentials of the two studied cyclodepsipeptides. A high correlation between 2,2-diphenyl-1-picrylhydrazyl (DPPH)-radical scavenging capacity and total reducing power were found. According to the density functional theory (DFT) calculations, the most probable mechanism of antioxidant action is hydrogen atom abstraction from the activated C-H group at 3-position in the morpholinedione ring. To the best of our knowledge this is the first report about the antioxidant properties of morpholine-2,5-diones derivatives.
