Allyl-containing sulfides in garlic increase uncoupling protein content in brown adipose tissue, and noradrenaline and adrenaline secretion in rats. (1/436)

The effects of garlic supplementation on triglyceride metabolism were investigated by measurements of the degree of thermogenesis in interscapular brown adipose tissue (IBAT), and noradrenaline and adrenaline secretion in rats fed two types of dietary fat. In Experiment 1, rats were given isoenergetic high-fat diets containing either shortening or lard with or without garlic powder supplementation (8 g/kg of diet). After 28 d feeding, body weight, plasma triglyceride levels and the weights of perirenal adipose tissue and epididymal fat pad were significantly lower in rats fed diets supplemented with garlic powder than in those fed diets without garlic powder. The content of mitochondrial protein and uncoupling protein (UCP) in IBAT, and urinary noradrenaline and adrenaline excretion were significantly greater in rats fed a lard diet with garlic powder than in those fed the same diet without garlic. Other than adrenaline secretion, differences due to garlic were significant in rats fed shortening, also. In Experiment 2, the effects of various allyl-containing sulfides present in garlic on noradrenaline and adrenaline secretion were evaluated. Administration of diallyldisulfide, diallyltrisulfide and alliin, organosulfur compounds present in garlic, significantly increased plasma noradrenaline and adrenaline concentrations, whereas the administration of disulfides without allyl residues, diallylmonosulfide and S-allyl-L-cysteine did not increase adrenaline secretion. These results suggest that in rats, allyl-containing sulfides in garlic enhance thermogenesis by increasing UCP content in IBAT, and noradrenaline and adrenaline secretion.  (+info)

Cytochrome P-450-dependent bioactivation of 1,1-dichloroethylene to a reactive epoxide in human lung and liver microsomes. (2/436)

We investigated the cytochrome P-450-dependent metabolism of 1, 1-dichloroethylene (DCE) by human lung and liver microsomes and compared the results from analogous experiments in mice. Metabolites were identified by HPLC analysis of their glutathione conjugates and/or hydrolyzed products and were detected by using [14C]DCE. The role of human CYP2E1 in the metabolic reactions was examined by comparing p-nitrophenol hydroxylase activities with levels of metabolites formed and by using the CYP2E1-selective inhibitor diallyl sulfone. The major products formed in microsomal incubations containing NADPH were the DCE-epoxide-derived glutathione conjugates 2-(S-glutathionyl)acetyl glutathione and 2-S-glutathionyl acetate. Lower levels of the acetal of 2,2-dichloroacetaldehyde were also detected. In lung samples from eight patients, the amounts of epoxide-derived conjugates formed ranged from 15.6 +/- 4.23 to 34.9 +/- 12.75 pmol/mg protein/min. The levels in murine lung were higher at 40.0 +/- 3.8 pmol/mg protein/min. In liver samples from five patients, conjugate levels ranged from 46.5 +/- 8.3 to 240.0 +/- 10. 5 pmol/mg protein/min, whereas levels in murine liver were 83.0 +/- 6.2 pmol/mg protein/min. Conjugate levels formed in human liver correlated with the relative levels of p-nitrophenol hydroxylase activity present, but this relationship was equivocal in human lung. Diallyl sulfone inhibited the formation of the glutathione conjugates (20-65%) in liver samples from all four patients, whereas only one of five human lung samples exhibited this inhibition (27%). These results demonstrated that the DCE-epoxide is a major metabolite formed by human microsomes and is mediated by CYP2E1 in liver and in some individuals in lung.  (+info)

Inhibition of nitrifiers and methanotrophs from an agricultural humisol by allylsulfide and its implications for environmental studies. (3/436)

Allylsulfide, an inhibitor of ammonia monooxygenase, was tested to determine its ability to inhibit nitrification and methane oxidation in pure cultures, in agricultural humisol enrichment cultures, and in humisol slurries. We confirmed that allylsulfide is a differential inhibitor of cultures of nitrifiers and methanotrophs at concentrations of 1 and 200 microM, respectively, which result in 50% inhibition. However, although a nitrifying enrichment culture added to sterilized humisol was inhibited 50% by 4 microM allylsulfide, 500 microM allylsulfide was necessary for 50% inhibition of the endogenous nitrifying activity in nonsterile humisol. We concluded that native nitrifiers were protected, possibly by being in colonial aggregates or sheltered microenvironments.  (+info)

Metabolism of diallyl disulfide by human liver microsomal cytochromes P-450 and flavin-containing monooxygenases. (4/436)

The metabolism of diallyl disulfide (DADS), a garlic sulfur compound, was investigated in human liver microsomes. Diallyl thiosulfinate (allicin) was the only metabolite observed and its formation followed Michaelis-Menten kinetics with a Km = 0.61 +/- 0.2 mM and a Vmax = 18.5 +/- 4.2 nmol/min/mg protein, respectively (mean +/- S.E. M., n = 4). Both flavin-containing monooxygenase and the cytochrome P-450 monooxygenases (CYP) were involved in DADS oxidation, but the contribution of CYP was predominant. The cytochrome P-450 isoforms involved in this metabolism were investigated using selective chemical inhibitors, microsomes from cells expressing recombinant CYP isoenzymes, and studying the correlation of the rate of DADS oxidation with specific monooxygenase activities of human liver microsomes. Diethyldithiocarbamate and tranylcypromine inhibited allicin formation, whereas other specific inhibitors had low or no effect. Most of the different human microsomes from cells expressing CYP were able to catalyze this reaction, but CYP2E1 showed the highest affinity with a substantial activity. Furthermore, allicin formation by human liver microsomes was correlated with p-nitrophenol hydroxylase activity, a marker of CYP2E1, and tolbutamide hydroxylase activity, a marker of CYP2C9. Among these approaches only CYP2E1 was identified in each case, which suggested that DADS is preferentially metabolized to allicin by CYP2E1 in human liver. However the minor participation of other CYP forms and flavin-containing monooxygenases is likely.  (+info)

In vivo formation and localization of 1,1-dichloroethylene epoxide in murine liver: identification of its glutathione conjugate 2-S-glutathionyl acetate. (5/436)

The hepatotoxic effects induced by 1,1-dichloroethylene (DCE) are ascribed to cytochrome P-450 (CYP) 2E1-dependent formation of metabolites including 2,2-dichloroacetaldehyde and the DCE-epoxide. The DCE metabolites detected in incubations of liver microsomes are the acetal, the hydrate of 2,2-dichloroacetaldehyde, and the epoxide-derived GSH conjugates 2-S-glutathionyl acetyl glutathione ([B]) and 2-S-glutathionyl acetate ([C]). This study was undertaken to determine whether these DCE metabolites are also formed in vivo in murine liver. HPLC analysis of cytosol isolated from the livers of mice treated with [(14)C]DCE showed that [C] was the major conjugate formed, with lower levels of formation of [B]. The acetal was not detected in the cytosol. The formation of the epoxide-derived GSH conjugates was dose-dependent at 25 to 225 mg/kg DCE and occurred coincidentally with levels of covalent binding of DCE at the same doses. The acetal and conjugates [B] and [C] were also detected in bile collected from mice treated with DCE. Pretreatment of mice with buthionine sulfoximine decreased sulfhydryl levels and formation of conjugate [C], and increased DCE binding to liver proteins. In contrast, the levels of [C] and DCE binding were both reduced significantly in mice pretreated with the CYP2E1 inhibitor diallyl sulfone. Immunohistochemical studies indicated that protein adducts and conjugate [C] were localized in centrilobular hepatocytes and corresponded with the sites where CYP2E1 resided. Pretreatment with buthionine sulfoximine increased the amount of immunostaining. However, pretreatment with diallyl sulfone markedly decreased immunostaining for [C] in the hepatocytes. These results showed that 2,2-dichloroacetaldehyde and the epoxide are formed from DCE in vivo.  (+info)

AIM: To study actions of allitridi extracted from garlic on intracellular calcium in isolated rat brain cells. METHODS: Brain cells were isolated from newborn rat brain with Fura 2-AM measurements of intracellular Ca2+ concentration ([Ca2+]i). RESULTS: Allitridi 1-100 mumol.L-1 concentration-dependently blocked increases of [Ca2+]i caused by potassium chloride and sodium glutamate (Glu) with IC50 of 59.7 and 69.9 mumol.L-1 respectively. Allitridi 100 mumol.L-1 blocked norepinephrine (Nor)-induced [Ca2+]i elevation. CONCLUSION: Allitridi is an effective agent for blocking the [Ca2+]i increase caused by potassium chloride, Nor and Glu.  (+info)

Roles of horizontal gene transfer and gene integration in evolution of 1,3-dichloropropene- and 1,2-dibromoethane-degradative pathways. (7/436)

The haloalkane-degrading bacteria Rhodococcus rhodochrous NCIMB13064, Pseudomonas pavonaceae 170, and Mycobacterium sp. strain GP1 share a highly conserved haloalkane dehalogenase gene (dhaA). Here, we describe the extent of the conserved dhaA segments in these three phylogenetically distinct bacteria and an analysis of their flanking sequences. The dhaA gene of the 1-chlorobutane-degrading strain NCIMB13064 was found to reside within a 1-chlorobutane catabolic gene cluster, which also encodes a putative invertase (invA), a regulatory protein (dhaR), an alcohol dehydrogenase (adhA), and an aldehyde dehydrogenase (aldA). The latter two enzymes may catalyze the oxidative conversion of n-butanol, the hydrolytic product of 1-chlorobutane, to n-butyric acid, a growth substrate for many bacteria. The activity of the dhaR gene product was analyzed in Pseudomonas sp. strain GJ1, in which it appeared to function as a repressor of dhaA expression. The 1,2-dibromoethane-degrading strain GP1 contained a conserved DNA segment of 2.7 kb, which included dhaR, dhaA, and part of invA. A 12-nucleotide deletion in dhaR led to constitutive expression of dhaA in strain GP1, in contrast to the inducible expression of dhaA in strain NCIMB13064. The 1, 3-dichloropropene-degrading strain 170 possessed a conserved DNA segment of 1.3 kb harboring little more than the coding region of the dhaA gene. In strains 170 and GP1, a putative integrase gene was found next to the conserved dhaA segment, which suggests that integration events were responsible for the acquisition of these DNA segments. The data indicate that horizontal gene transfer and integrase-dependent gene acquisition were the key mechanisms for the evolution of catabolic pathways for the man-made chemicals 1, 3-dichloropropene and 1,2-dibromoethane.  (+info)

Ethanol and arachidonic acid increase alpha 2(I) collagen expression in rat hepatic stellate cells overexpressing cytochrome P450 2E1. Role of H2O2 and cyclooxygenase-2. (8/436)

The ability of ethanol and arachidonic acid (AA), as inducers of oxidative stress and key factors in alcoholic liver disease, to up-regulate alpha 2 collagen type I (COL1A2) gene expression was studied in a hepatic stellate cell line overexpressing the ethanol-inducible cytochrome P450 2E1 (CYP2E1) (E5 cells). A time- and dose-dependent induction in COL1A2 mRNA by ethanol or AA was observed that was prevented by diallylsulfide, a CYP2E1 inhibitor. Nuclear run-on experiments showed transcriptional activation of the COL1A2 gene by ethanol and AA. Catalase abrogated the increase in COL1A2 mRNA suggesting an H(2)O(2)-dependent mechanism. Cyclooxygenase-2 (COX-2) levels and production of prostaglandin E(2) upon addition of AA were elevated in the E5 cells. Incubation with NS-398, a COX-2 inhibitor, blocked the effect of AA, but not of ethanol, on COL1A2 expression suggesting that CYP2E1 activates COX-2 expression, and the oxidation of AA by COX-2 is responsible for the increase in COL1A2. Activity of a reporter construct driven by -378 base pairs of the proximal promoter region of the COL1A2 gene increased in E5 but not control cells and was further increased by ethanol or AA. These experiments link CYP2E1-dependent oxidative stress to induction of COX-2 and the actions of ethanol and AA on activation of collagen gene expression in hepatic stellate cells.  (+info)

Diallyl trisulfide (DATS), also known as Allitridin, is an organosulfur compound with the formula S(SCH2CH=CH2)2. It is one of several produced by the hydrolysis of allicin, including diallyl disulfide and diallyl tetrasulfide, DATS is one of the most potent. Many health benefits of garlic are attributed in part to DATS. These benefits include anti-cancer effects, platelet aggregation, blood pressure reduction, decreases in cholesterol levels, and increases in levels of reactive oxygen species. DATS has been shown to selectively kill cancerous cells in the prostate and breast, leaving healthy cells unharmed. This effect is attributed to increased reactive oxygen species (ROS) within cancer cells, increased the number of cells that arrest in the G2 phase of mitosis, and promote an increase in caspase-3 activity. These effects appear to contribute to the apoptosis of cancer cells and a decrease in cancer cell proliferation. DATS can be metabolized by glutathione in red blood cells to form hydrogen ...

Diallyl sulfide (DAS), diallyl disulfide (DADS) and diallyl trisulfide (DATS) are major oil-soluble organosulfur compounds of garlic responsible for most of its pharmacological effects. The present study investigated the influence of repeated intraperitoneally (ip) administration of DAS, DADS and DATS on the total level of sulfane sulfur, bound sulfur (S-sulfhydration) and hydrogen sulfide (H2S) and on the activity of enzymes, which catalyze sulfane sulfur formation and transfer from a donor to an acceptor in the normal mouse kidney, i.e., γ-cystathionase (CSE) and rhodanese (TST). The activity of aldehyde dehydrogenase (ALDH), which is a redox-sensitive protein, containing an -SH group in its catalytic center, was also determined. The obtained results indicated that all tested compounds significantly increased the activity of TST. Moreover, DADS and DATS increased the total sulfane sulfur level and CSE activity in the normal mouse kidney. ALDH activity was inhibited in the kidney after DATS
1574 Epidemiological data continues to support the notion that increased consumption of Allium vegetables may reduce the risk for different types of malignancies including cancer of the prostate. Moreover, allium vegetable derived organosulfur compounds, such as diallyl trisulfide (DATS; CH2=CH-CH2-(S)3-CH2-CH=CH2), are highly effective in affording protection against cancer development in animal models. Evidence is mounting to indicate that garlic-derived organosulfur compounds can suppress proliferation of cultured cancer cells by inhibiting cell cycle progression and causing apoptosis induction. Previous studies including those from our laboratory have offered novel insights into the mechanism of apoptosis induction by DATS. For instance we showed previously that DATS-induced apoptosis in PC-3 and DU145 human prostate cancer cells was associated with c-jun N-terminal kinase mediated phosphorylation of Bcl-2, which reduced Bax-Bcl-2 interaction to trigger activation of caspase-9/3.

Allylstannanes are relatively stable reagents in the allylmetal family, and have been employed in a variety of complex organic syntheses. In fact, allylstannane addition is one of the most common methods for producing polypropionates, polyacetates, and other oxygenated molecules with a contiguous arrays of stereocenters.[10] Ley and coworkers[11] used an allylstannane to allylate a threose-derived aldehyde (see figure) en route to the macrolide antascomicin B, which structurally resembles FK506 and rapamycin, and is a potent binder of FKBP12. Allylboration is also often used to add allyl groups in a 1,2 fashion to aldehydes and ketones. Thanks to decades of research, there is now a wide variety of organoboron reagents available to the synthetic chemist, including organoboranes that predictably yield products in high diastereo- and enantioselectivity.[12] If a one-pot metal insertion and allylation procedure is required, indium- mediated allylation is an attractive option for generating ...
A number of studies on garlic have appeared dealing with diallyl sulfide and cancer. One from the Republic of Korea cites diallyl disulfide (DADS) as the most prevalent oil-soluble sulfur compound in garlic, inhibiting cell proliferation in many cell lines. Scientists there examined DADS ability to kill cells in a process involving free radical production. They found that the famous tumor suppressor gene, p53, arrested the cell cycle when DADS treatment was present. Cancer cells died following 24 hour DADS treatment that activated the p53 gene. They also found that DADS induced cell death was prevented by treatment with a compound known to prevent p53 dependent cell death by reducing free radical levels in the mitochrondria, the cellular furnaces. Their results showed that mitochrondrial free radicals may serve as second messengers in DADS-induced cell death, which requires activation of p53. That study was found in the Journal of Biochemical and Molecular Toxicology ...

Diallyl sulfide (DAS) and diallyl disulfide (DADS) are natural components that could account for the anticarcinogenic properties of garlic, at least in part, through the activation of xenobiotic detoxifying metabolism. The aim of this work was to describe the effect of DAS and DADS on xenobiotic-related gene expressions and to study molecular mechanisms relaying DAS effect. We describe the different effects of DAS and DADS on hepatic CYP2B1/2, CYP3A and epoxide hydrolase (EpH) mRNAs in rats, in terms of activation profile, doses and kinetics. The activation profile varied with the mode of chemical administration, i.e. gastric infusion or intraperitoneal (i.p.) injection. Using gastric infusion, DAS and DADS proved different efficiencies at enhancing the mRNA level of the three drug-metabolizing enzymes. After an i.p. administration, we observed a specific activation of CYP2B1/2 gene by DAS. The DAS-mediated CYP2B1/2 activation occurred at transcriptional level and through an okadaic ...

AR plays an important role in the development of prostate cancer as well as in the transition to castration-resistant state, which is highly aggressive and resistant to chemotherapy (4, 38). Thus, the preclinical/clinical development of novel agents that are safe but can suppress AR signaling is highly desirable. The present study shows that DATS treatment suppresses protein level of AR in both LNCaP cells and their androgen-independent variant. The DATS-mediated AR protein down-regulation is maintained for at least up to 24 hours even after removal of the drug. In addition, DATS treatment exhibits significant antiproliferative effect against androgen-stimulated growth of LNCaP cells.. We also conclude that the DATS-mediated suppression of AR protein level leads to inhibition of transcriptional activity of AR as evidenced by a significant decrease in secreted as well as intracellular levels of PSA in both LNCaP and C4-2 cells. Structure-activity analysis reveals that even a subtle change in the ...
