Mechanism of Action

In vitro	Allicin is readily permeable through phospholipid membranes aiding its biological activity. It inhibits the growth of cancer cells of murine and human origin. This compound induces the formation of apoptotic bodies, nuclear condensation and a typical DNA ladder in cancer cells. Furthermore, activation of caspases-3, -8 and -9 and cleavage of poly(ADP-ribose) polymerase are induced by this chemical. It is highly reactive with thiol-groups but under certain conditions it also reacts with itself forming further compounds which can also be bioactive, such as vinyl-dithiins, ajoene and polysulfanes. Since this substance is able to oxidize biomolecules such as glutathione or protein cysteine residues under physiological conditions, it fulfils the definition of a Reactive Sulfur Species (RSS). It certainly acts as a “physiological antioxidant” by inducing the cellular “phase II detoxification system”. This agent activates the redox-dependent mammalian transcription factor Nrf-2 the localization of which depends upon the Keap1 protein (Kelch-like ECH1-associated protein), presumably by oxidizing the regulatory cysteine-residues, as demonstrated for the YAP1-transcription factor which is a functional homologue of the Nrf-2 system in yeast. In vitro studies show that it inhibits TNF-α-mediated T cell adhesion to extracellular matrix components and to endothelial cells. It also inhibits TNF-α-mediated intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 expression on human vascular endothelial cells.
In vivo	Allicin has a protective effect on immune-mediated, Con A-induced hepatitis in mice.
