Diallyl disulfide (DADS) is one of the major volatile degradative garlic compounds and some neuroprotective effects in animal models of AD and anti-cancer (e.g., inhibition of oxidative stress, cellular apoptosis, angiogenesis, and GSK-3β/NF-κB-associated signaling) has been also established [128]. This evidence concerns the gene GSK3B and Alzheimer disease.
