Nitrone derivatives of trolox as neuroprotective agents
摘要:
Synthesis of nitrone derivatives of trolox is described. Their biological evaluation was performed in vitro for scavenging different free radicals, inhibiting Fe2+-induced lipid peroxidation, and in vivo in a permanent middle cerebral artery occlusion model in mice. New compounds exert pharmacological activities comparable to or better than those of trolox or nitrone-type reference compounds. (c) 2005 Elsevier Ltd. All rights reserved.
Synthesis of C-aryl-N-cyclopropylnitrones is described. Preparations were performed either by condensation of the appropriate aldehyde with N-cyclopropyl-hydroxylamine, or oxidation of N-substituted N-cyclopropylamines with sodium tungstate/hydrogen peroxide.
