Antioxidant Properties of a Nanostructured Clathrate Complex Selenopyran with ß-Cyclodextrin in Model Systems of Oxidative Stress.

We studied the effect of nanostructured clathrate complex 9-phenyl-symm-octahydoselenoxanthene (selenopyran) with ß-cyclodextrin on the generation of ОН· radicals in the Fenton system and parameters of oxidative stress in rat liver cells incubated at 37°Ð¡ for 1 h. The complex inhibits the development of free-radical oxidative processes induced by ROS and the most toxic ОН· radicals, reduces the increased level of ROS induced by prooxidants, and exhibits antioxidant activity.
