General description

S-Allyl-L-cysteine has anti-inflammatory properties. It inhibits prooxidant enzymes and chelates metals. S-Allyl-L-cysteine exhibits hypoglycemic and cholesterol-lowering effects. It prevents apoptosis, lowers the activity of inducible nitric oxide synthase and blocks nuclear factor kappa B activity.

Biochem/physiol Actions

S-allyl-L-cysteine is a sulfur containing amino acid found in garlic with antioxidant, anti-cancer, antihepatotoxic, neuroprotective and neurotrophic activity. S-allyl-L-cysteine has potent activity in several animal models of ischemic injury and Alzhemer′s disease.

S-Allylcysteine (SAC), the most abundant organosulfur compound in aged garlic extract, has multifunctional activity via different mechanisms and neuroprotective effects that are exerted probably via its antioxidant or free radical scavenger action. The 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-treated mouse has been the most widely
