In  vitro free radical scavenging capacity of dimethylglycine sodium salt and its protective ability against oleic acid hydroperoxide-induced oxidative damage in IPEC-J2 cells.

In vitro free radical scavenging capacity of dimethylglycine sodium salt and its protective ability against oleic acid hydroperoxide-induced oxidative damage in IPEC-J2 cells. Int J Mol Med. 2018 Sep 13;: Authors: Bai K, Jiang L, Zhang L, Zhao Y, Lu Y, Zhu J, Cai J, Zhang L, Wang T Abstract The aim of the present study was to evaluate the in vitro free radical scavenging capacity of dimethylglycine sodium (DMG‑Na) and its protective ability against oleic acid hydroperoxide (OAHPx)‑induced oxidative damage in IPEC‑J2 cells. Initially, the free radical scavenging activities of water‑soluble pigments (DMG‑Na, betalain, capsanthin and cyanidin‑3‑rutinoside) were measured and compared with those of Trolox. Subsequently, freshly collected swine blood was mixed with heparin and centrifuged to obtain erythrocytes. In order to induce the free radical chain oxidation in erythrocytes, the aqueous peroxyl radicals were generated by thermal decomposition of 2,2'‑azobis(2‑amidinopropane) dihydrochloride (AAPH) in oxygen. A 2% suspension of porcine erythrocytes in PBS buffer were pre‑incubated for 30 min at 37˚C with DMG‑Na (32 µM), followed by incubation with or without AAPH (75 mM) for 5 h with gentle shaking. Additionally, IPEC‑J2 cells were randomly assigned to four groups (n=6 per group): Cells treated with phosphate buffered saline (PBS); cells treated with DMG‑Na (32 µM); cells treated with oleic acid hyd...
