Diallyl disulfide (DADS) or allyl disulfide is the main organosulfur ingredient in garlic, with known antioxidant and anti-inflammatory activities. It has been shown to have multi-targeted antitumor activities in a variety of cancer cells Experiments in vitro have revealed, that diallyl disulfide inhibits the metastasis of type Ⅱ esophageal-gastric junction adenocarcinoma cells via NF-κB and PI3K/AKT signaling pathways. At the same time, was shown the drug suppresses cell stemness, proliferation, metastasis and glucose metabolism in breast cancer stem cells partly through the inhibition of CD44/PKM2/AMPK. Besides diallyl disulfide can be a promising agent for the treatment of emphysema, this was discovered in experiments on rats. And also drug shows protective effects against acetaminophen (AAP)-induced acute hepatotoxicity.
