3-(allylsulphinyl)-L-alanine

Alliin is a cysteine sulfoxide constituent of garlic that is converted by alliinase to allicin, which imparts its pungent aroma and flavor. Alliin exhibits anti-cancer, anti-microbial, anti-hypertensive, cardioprotective, and anti-oxidant activities. It has been shown to inhibit squalene monooxygenase, a rate-limiting step in the downstream pathway of cholesterol biosynthesis, with an IC₅₀ value of 120 μM.

(±)-L-Alliin has been used in nutrient broth No. 2 (NB2) for determining the concentrations of garlic-derived products active against Clostridium jejuni.

rac-Alliin has shown notable preventive effects on cardiac marker enzymes and lipids in isoproterenol-induced myocardial injury. rac-Alliin is also known to exhibit anticancer, antimicrobial, antihypertensive, antioxidant activities.

ChEBI: 3-(Allylsulphinyl)-L-alanine is a L-alpha-amino acid.

Alliin is the precursor of allicin.

S-Allyl-L-cysteine ((±)-L-Alliin) (SAC) may be used to study its potential as an anti-Alzheimer′s factor. SAC has been shown to increase cell proliferation and neuroblast differentiation by increasing 5-HT(1A) and provide antioxidative benefit to neurons and synapses.
