La proprietà antiossidante della melatonina contro l'ischemia cerebrale



In questo articolo scientifico sono stati analizzati e raccolti numerosi studi che documentano la capacità della melatonina nel limitare i danni molecolari ed i danni ai tessuti degli organi in caso di danno neuronale da ischemia-riperfusione (ictus).

Abstract
This review briefly summarizes some of the large amount of data documenting the ability of melatonin to limit molecular and organ tissue damage in neural ischemia-reperfusion injury (stroke), where free radicals are generally considered as being responsible for much of the resulting tissue destruction. Melatonin actions that have been identified include its ability to directly neutralize a number of toxic reactants and stimulate antioxidative enzymes. Furthermore, several of its metabolites such as N(1)-acetyl-N(2)-formyl-5- methoxykynuramine (AFMK) and N(1)-acetyl-5-methoxykynuramine (AMF), are themselves scavengers suggesting that there is a cascade of reactions that greatly increase the efficacy of melatonin. However, the mechanisms by which melatonin is protective in such widely diverse areas of the cell and different organs are likely not yet all identified.
