(E)-Ajoene is a disulfide that has been found inA. sativumand has diverse biological activities.1,2,3,4It is active against Gram-positive and Gram-negative bacteria (MICs = 10-250 and 150->500 μg/ml, respectively) and fungi (MICs = 15-50 μg/ml).1(E)-Ajoene inhibits proliferation of a variety of cancer cells, including MDA-MB-231 breast, HeLa cervical, and WHCO1 esophageal cancer cells (IC50s = 18.6, 61, and 39.2 μM, respectively).2It also inhibits human glutathione reductase andT. cruzitrypanothionereductase when used at a concentration of 200 μM.3(E)-Ajoene (25 mg/kg) is neuroprotective in a gerbil model of ischemia-reperfusion injury, reducing reactive astrocytosis and microgliosis in the hippocampal CA1 region.4 1.Yoshida, H., Iwata, N., Katsuzaki, H., et al.Antimicrobial activity of a compound isolated from an oil-macerated garlic extractBiosci.
