Allicin

Allicin is a natural product originally isolated from A. sativum that has wide-ranging biological effects including antioxidative, anticancer, antimicrobial, and antifungal activities.^1,2,3,4 It inhibits the cysteine proteases cathepsin B and L, facipain 2, and rhodesain with K_i values of 8.6 and 9.3, 1.04, and 5.31 µM, respectively.⁵ It shows antiparasitic activity against P. falciparum (IC₅₀ = 5.2 µM) and T. b. brucei (IC₅₀ = 13.8 µM), the parasites that cause malaria and African sleeping sickness, respectively. Allicin (5-10 µM) dose-dependently inhibits cell adhesion, invasion, and migration in various lung adenocarcinoma cell lines.² It also alters the balance of tissue inhibitors of matrix metalloproteinases (TIMPs) and matrix metalloproteinases (MMPs), decreases phosphorylation of Akt, and decreases PI3K/Akt signaling.

WARNING This product is not for human or veterinary use.
