tetrasulfide/ネギ属

Epidemiological evidence indicates that a high dietary intake of plants of the Allium family, such as garlic and onions, decreases the risk of cancer in humans. It has been suggested that this effect is due to the ability of the aliphatic mono-, di-, tri-, and tetrasulfides derived from these

Cadmium (Cd) is an environmental and industrial pollutant that affects various organs in humans and animals. A body of evidence has accumulated implicating the free radical generation with subsequent oxidative stress in the biochemical and molecular mechanisms of Cd toxicity. Since kidney is the

Cadmium (Cd) is a neurotoxic metal, which induces oxidative stress and membrane disturbances in nerve system. The garlic compound diallyl tetrasulfide (DTS) has the cytoprotective and antioxidant activity against Cd induced toxicity. The present study was carried out to investigate the efficacy of

Cadmium (Cd)-induced oxidative damage is the most serious problem that leads to reproductive system failure in both human and animals. Our previous studies indicate that diallyl tetrasulfide (DTS) from garlic has the cytoprotective and antioxidant activity against Cd-induced toxicity in vivo and in

The protective efficacy of diallyl tetrasulfide (DTS) from garlic on liver injury induced by cadmium (Cd) was investigated. In this study, Cd (3 mg/kg body weight) was administered subcutaneously for 3 weeks to induce toxicity. DTS was administered orally (10, 20 and 40 mg/kg body weight) for 3

Lipoprotein abnormalities disrupt the levels of serum and cellular lipid, which accounts for the genesis of cardiovascular diseases. Cadmium (Cd) exposure is associated with a number of distinct pathological changes including dyslipidemia. Garlic and its organosulfur compounds seem to hold promise

Cadmium (Cd) induces extensive membrane damage that contributes to the cytotoxic effect of Cd. We studied the effect of diallyl tetrasulfide (DTS) from garlic on Cd-induced changes in lipid peroxidation and membrane-bound enzymes in liver, kidney, and testis of rats. Cadmium exposure (3 mg/kg body

BACKGROUND Diallyl mono- and polysulfanes from garlic are known to induce an adaptive cell response and the formation of antioxidants in cancer cells. In the case of a severe ER stress and a failure in the response, cancer cells eventually go into apoptosis. Only little is known about the response

For many years, in vitro and in vivo studies have reported that organosulfur compounds (OSCs), naturally found in Allium vegetables, are able to suppress the proliferation of various tumor cells. In spite of recent advances, the specific molecular mechanisms involved in OSC activity are still

Garlic-derived organosulfur compounds including diallyl polysulfides are well known for various health-beneficial properties and recent reports even point to a potential role of diallyl polysulfides as chemopreventive and therapeutic agents in cancer treatment due to their selective

The essential oils of garlic and onion and their constituent sulfides with three or more sulfur atoms were potent inhibitors of yeast growth. The minimum inhibitory concentrations of garlic oil, onion oil, diallyl trisulfide, diallyl tetrasulfide, and dimethyl trisulfide for all the yeasts tested

Volatile components were isolated from Chinese chive and rakkyo by simultaneous steam distillation-solvent extraction and analyzed by GC and GC-MS. Sulfur compounds account for 88 and 94% of the total volatiles in the isolated extract of Chinese chive and rakkyo, respectively. In addition to the

Vibrio cholera is a major foodborne pathogen in Thailand. It is present in raw and lightly cooked foods, and it causes cholera. Natural products inhibiting it can be used to improve the safety of foods. In this study, elephant garlic oil was studied for its major diallyl sulfide content and its

Oxidative stress and mitochondrial injury has been implicated in cadmium-induced apoptosis. In this study, we examined the protective effect of diallyl tetrasulfide from garlic on cadmium induced oxidative stress and apoptosis in vero cells. Exposure of vero cells to cadmium (10 microM) for 18 h

Five compounds oxidizing canine erythrocytes were isolated from an aqueous ethanol garlic extract by silica gel column chromatography and preparative thin-layer chromatography. On the basis of nuclear magnetic resonance, infrared spectroscopy, and mass spectrometry, they were identified as three
