Amidinoquinoxaline-Based Nitrones as Lipophilic Antioxidants

open access: yesAntioxidants, 2021
The potential of nitrones (N-oxides) as therapeutic antioxidants is due to their ability to counteract oxidative stress, mainly attributed to their action as radical scavengers toward C- and O-centered radicals.

Nitrones as therapeutics [PDF]

open access: yesFree Radical Biology and Medicine, 2008
Nitrones have the general chemical formula X-CH=NO-Y. They were first used to trap free radicals in chemical systems and then subsequently in biochemical systems. More recently several nitrones, including alpha-phenyl-tert-butylnitrone (PBN), have been shown to have potent biological activity in many experimental animal models.
