Differential effects of allyl sulfides from garlic essential oil on cell cycle regulation in human liver tumor cells.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

In this study, diallyl sulfide (DAS), diallyl disulfide (DADS) and diallyl trisulfide (DATS), which are major organosulfur compounds (OSCs) of garlic, were used as experimental materials to investigate their modulation effects on cell viability and cell cycle in human liver tumor cells (J5).

Molecular mechanisms of garlic-derived allyl sulfides in the inhibition of skin cancer progression.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Skin cancer is a serious concern whose incidence is increasing at an alarming rate. Allyl sulfides-i.e., sulfur metabolites in garlic oil-have been demonstrated to have anticancer activity against several cancer types, although the mechanisms underlying these effects remain enigmatic. Our previous

Allyl sulfides inhibit cell growth of skin cancer cells through induction of DNA damage mediated G2/M arrest and apoptosis.

Diallyl sulfide (DAS), diallyl disulfide (DADS), and diallyl trisulfide (DATS), extracted from crushed garlic by steam-distillation, have been reported to provide the anticancer activity in several cancer types. However, their mechanisms of effects on skin cancer cells remain unclear. Therefore, we

Allyl sulfides from garlic suppress the in vitro proliferation of human A549 lung tumor cells.

The present studies compared the antiproliferative effects of diallyl trisulfide (DATS) and diallyl disulfide (DADS) on cultured human neoplastic (A549) and nonneoplastic (MRC-5) lung cells. Addition of 10 microM DATS reduced A549 growth by 47%, whereas 10 microM DADS decreased growth by only 20%.

Garlic-derived allyl sulfides in cancer therapy.

Garlic (Allium sativam L.) is widely used in traditional herbal remedies and alternative medicine. The potential health benefits of garlic are largely attributed to its metabolic byproducts. Extensive in vivo and in vitro studies has demonstrated that the garlic derivatives possess anti-cancer

Possible mechanism by which allyl sulfides suppress neoplastic cell proliferation.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Both oil- and water-soluble allyl sulfur compounds from garlic have been found to possess antitumorigenic properties. These antitumorigenic properties increase as exposure increases both in vitro and in vivo. Generally, oil-soluble allyl sulfur compounds are more effective antiproliferative agents

Inhibition by allyl sulfides and crushed garlic of O6-methylguanine formation in liver DNA of dimethylnitrosamine-treated rats.

Garlic consumption is linked with lower incidences of certain cancers perhaps because garlic-derived allyl sulfides inhibit nitrosamine activation by cytochrome P450s. To help evaluate this view, effects of allyl sulfides on O6-methylguanine (O6MG) levels were examined in liver of rats injected with

Anticancer activity of S-allylmercapto-L-cysteine on implanted tumor of human gastric cancer cell.

Allylmercapto glutathione S-conjugate, S-allylmercapto-L-cysteine (SAMC), which is biotransformed from allyl sulfides and from naturally occurring water-soluble garlic derivatives, has been known to inhibit tumorigenesis. We found that SAMC was able to induce apoptosis in gastric cancer cells in

Inhibition by allyl sulfides and phenethyl isothiocyanate of methyl-n-pentylnitrosamine depentylation by rat esophageal microsomes, human and rat CYP2E1, and Rat CYP2A3.

Garlic and Cruciferae are associated with reduced risks of several human cancers, and some of their constituents are anticarcinogenic in animals. Here we studied inhibition of in vitro metabolism of the rat esophageal carcinogen methyl-n-pentylnitrosamine (MPN) by garlic-derived allyl sulfides and

Diallyl trisulfide inhibits phorbol ester-induced tumor promotion, activation of AP-1, and expression of COX-2 in mouse skin by blocking JNK and Akt signaling.

An inverse relationship exists between the consumption of garlic and the risk of certain cancers. The present study was aimed at investigating the effect of garlic constituent diallyl trisulfide (DATS) on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced cyclooxygenase-2 (COX-2) expression and

Allyl sulfides modify cell growth.

Extensive evidence points to the ability of allyl sulfides from garlic to suppress tumor proliferation both in vitro and in vivo. This antineoplastic effect is generally greater for lipid-soluble than water-soluble allyl sulfides. Both concentration and duration of exposure can increase the

Dietary compounds that induce cancer preventive phase 2 enzymes activate apoptosis at comparable doses in HT29 colon carcinoma cells.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Dietary agents that induce glutathione S-transferases and related detoxification systems (Phase 2 enzyme inducers) are thought to prevent cancer by enhancing elimination of chemical carcinogens. The present study shows that compounds of this group (benzyl isothiocyanate, allyl sulfide, dimethyl

Diallyl trisulfide suppresses the proliferation and induces apoptosis of human colon cancer cells through oxidative modification of beta-tubulin.

Allyl sulfides are characteristic flavor components obtained from garlic. These sulfides are thought to be responsible for their epidemiologically proven anticancer effect on garlic eaters. This study was aimed at clarifying the molecular basis of this anticancer effect of garlic by using human

Nonsteroidal anti-inflammatory drug activated gene-1 (NAG-1) modulators from natural products as anti-cancer agents.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Natural products are rich sources of gene modulators that may be useful in prevention and treatment of cancer. Recently, nonsteroidal anti-inflammatory drug (NSAID) activated gene-1 (NAG-1) has been focused as a target of action against diverse cancers like colorectal, pancreatic, prostate, and

Anti-invasive activity of diallyl disulfide through tightening of tight junctions and inhibition of matrix metalloproteinase activities in LNCaP prostate cancer cells.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Diallyl disulfide (DADS) is a major component of an oil-soluble allyl sulfide garlic (Allium sativum) derivative, which has been shown to exert a potential for anti-cancer activity. However, the biochemical mechanisms underlying DADS-induced anti-invasiveness and anti-metastasis have not been
