Journal ArticleDOI
One molecule, many derivatives: a never-ending interaction of melatonin with reactive oxygen and nitrogen species?
TL;DR: This review focuses on melatonin metabolism which includes the synthetic rate‐limiting enzymes, synthetic sites, potential regulatory mechanisms, bioavailability in humans, mechanisms of breakdown and functions of its metabolites.
Journal ArticleDOI
Actions of melatonin in the reduction of oxidative stress
TL;DR: Melatonin was discovered to be a direct free radical scavenger less than 10 years ago and besides its ability to directly neutralize a number of free radicals and reactive oxygen and nitrogen species, it stimulates several antioxidative enzymes which increase its efficiency as an antioxidant.
Journal ArticleDOI
Melatonin as an antioxidant: under promises but over delivers.
Russel J. Reiter,Juan C. Mayo,Dun Xian Tan,Rosa M. Sainz,Moisés Alejandro Alatorre-Jiménez,Lilian Qin +5 more
TL;DR: It is the current feeling of the authors that, in view of the widely diverse beneficial functions that have been reported for melatonin, these may be merely epiphenomena of the more fundamental, yet‐to‐be identified basic action(s) of this ancient molecule.
Journal ArticleDOI
Melatonin as a natural ally against oxidative stress: a physicochemical examination
TL;DR: In this article, a review summarizes the current progress in understanding the physicochemical insights related to the free radical-scavenging activity of melatonin and concludes that melatonin efficiently protects against oxidative stress by a variety of mechanisms.
Journal ArticleDOI
Chemical and physical properties and potential mechanisms: melatonin as a broad spectrum antioxidant and free radical scavenger.

TL;DR: Under in vivo conditions, melatonin is often several times more potent than vitamin C and E in protecting tissues from oxidative injury when compared at an equivalent dosage (micromol/kg).
