The neuroprotective properties of S-allyl cysteine (SAC) have been demonstrated in different neurotoxic paradigms, and it may be partially attributable to its antioxidant and anti-inflammatory profile. Recently, SAC has also been shown to induce neuroprotection in the rat striatum in a toxic model induced by 6-hydroxydopamine in rats through a concerted(More)
Aged garlic extract (AGE) is an odorless garlic preparation containing S-allylcysteine (SAC) as its most abundant compound. A large number of studies have demonstrated the antioxidant activity of AGE and SAC in both in vivo--in diverse experimental animal models associated to oxidative stress--and in vitro conditions--using several methods to scavenge(More)
Selenium (Se) is a crucial element exerting antioxidant and neuroprotective effects in different toxic models. It has been suggested that Se acts through selenoproteins, of which thioredoxin reductase (TrxR) is relevant for reduction of harmful hydroperoxides and maintenance of thioredoxin (Trx) redox activity. Of note, the Trx/TrxR system remains poorly(More)
Oxidative stress plays an important role in neurodegenerative diseases and aging. The cellular defense mechanisms to deal with oxidative damage involve the activation of transcription factor related to NF-E2 (Nrf2), which enhances the transcription of antioxidant and phase II enzyme genes. S-allylcysteine (SAC) is an antioxidant with neuroprotective(More)
