V36 87 (1985)]**PEER REVIEWED** The cytotoxicity of eugenol to replicating cells, as mediated by the intracellular level of glutathione and by metabolic activation, was evaluated with the neutral red assay. The cytotoxicity of eugenol to human HFF fibroblasts and human HepG2 hepatoma cells was increased somewhat in the presence of a hepatic S9 microsoma fraction from Aroclor induced rats or hamsters. Exposure of human HepG2 hepatoma cells to eugenol depleted the level of intracellular glutathione. Cells treated with 1-chloro-2,4-dinitrobenzene or buthionine sulphoximine, agents that deplete intracellular glutathione, were hypersensitive to eugenol. A 1 hr pretreatment with 1- chloro-2,4-dinitrobenzene enhanced the cytotoxicity of eugenol, as did a 24 hr pretreatment with buthionine sulphoximine. Intracellular glutathione levels were, apparently significant in mediating the toxicity of eugenol. [Babich H et al; Toxicol In Vitro 7 (2): 105-9 (1993)]**PEER REVIEWED** 84 patients with contact dermatitis (38 dentists, 18 dental nurses and 28 dental technicians) were studied. All were patch tested with standard patch test series of the Council for Mutual Economic Assistance countries and with some professional allergens. 31 (36.9%) of them had allergic occupational contact dermatitis and 39 (46.2%) had irritant contact dermatitis. The highest prevalence of irritant contact dermatitis was found among dental surgeons. The percentage of atopics in the group of patients with irritant contact dermatitis was twice greater compared to that in the group of patients with allergic contact dermatitis. The contact allergens most frequently encountered were acrylic compounds, disinfectants (eugenol, thymol, trioxymethylene) mercury compunds and anesthetics.

New York: Pergamon Press, 1979. 377]**PEER REVIEWED** Bioassay directed fractionation of clove terpenes from the plant Eugenia caryophyllata has led to the isolation of the following five active known compounds: betacaryophyllene, beta-caryophyllene oxide, alpha-humulene, alpha-humulene epoxide I, and eugenol. Their structures were determined on the basis of spectral analysis. These compounds showed significant activity as inducers of the detoxifying enzyme glutathione S-transferase in the mouse liver and small intestine. The ability of natural anticarcinogens to induce detoxifying enzymes has been found to correlate with their activity in the inhibition of chemical carcinogenesis. Thus, these sesquiterpenes show promise as potential anticarcinogenic agents.

Betel leaf and its constituents decreased the number of papillomas per animal with the maximum protection, considering molar dosage, exhibited by beta-carotene and alpha-tocopherol. Except for beta-carotene, eugenol, hydroxychavicol and alpha-tocopherol increased the levels of reduced glutathione in the liver while glutathione S-transferase activity was enhanced by all except eugenol. [Bhide SV et al; J Ethnopharmacol 34 (2-3): 207-13 (1991)]**PEER REVIEWED** Regulatory guidelines suggest testing chemicals up to cytotoxic doses in chromosomal aberration assays. To investigate the utility and limitations of various cytotoxicity indicators Chinese hamster ovary cells were used to test 8 chemicals with differing ratios of cytotoxicity to clastogenicity. Immediate or delayed cell killing and growth inhibition (adenosine triphosphate levels, cell counts, colony-forming efficiency) and cell-cycle perturbations (mitotic index; average generation time) were measured. Aberrations were scored 10 and 24 hr from the beginning of the 3 hr treatment. All 8 compounds induced aberrations at concentrations that reduced cell growth at 24 hr by 50% or less. Concentrations of each chemical which induced at least 15% cells with aberrations, gave little loss of colony-forming efficiency (0-20%) for mitomycin C, adriamycin, cadmium sulfate and 2,6-diaminotoluene in contrast to the marked loss of colony-forming efficiency (70-80%) for eugenol, 2-aminobiphenyl and 8-hydroxyquinoline. 2,4Diaminotoluene was intermediate. Higher aberration yields were found at 24 hr than at 10 hr, even when minimal cell cycle delay was detected by average generation time estimates from BrdUrd labeled cells. Cells with multiple aberrations were seen at 24 but not at 10 hr, and often confirmed clastogenicity when there was only a weak increase in the percentage of cells with aberrations. Total adenosine triphosphate per culture did not always correlate with cell number, especially at later times after treatment. This is likely due to metabolic perturbations or altered cell biomass that are known to affect cell adenosine triphosphate content. Mitotic index suppression often did not correlate with average generation time, eg, only small increases in average generation time were seen for 8- hydroxyquinoline, 2,4-diaminotoluene and eugenol despite severe mitotic suppression at 10 hr. By 24 hr the mitotic index for all chemicals had recovered, sometimes exceeding control levels. Marked mitotic accumulation was seen at 10 hr for 2,4-diaminotoluene, indicating cell synchrony. Thus, the mitotic index has limited value for dose selection. In conclusion, even weakly active chemicals were detected at a single time without exceeding a 50% growth reduction at 24 hr. [Armstrong MJ et al; Mutat Res 265 (1): 45-60 (1992)]**PEER REVIEWED** Choice of harvest time is one of the most important variables in the assessment of whether a compound is clastogenic and in establishing a dose relation. The effects of sampling time on aberration yield was examined for 7 diverse chemicals in Chinese hamster ovary cells by harvesting at intervals from 9 to 30 hr after treatment for 3 hr with or without S9 metabolic activation. Both the percentage of aberrant cells and the total number of aberrations were observed. Data suggest that for most compounds a single harvest time approximately 17-21 hr after the beginning of a 3 hr treatment is optimal for aberration detection in Chinese hamster ovary cells. Maximal aberration yields were observed for eugenol from 15 to 21 hr. The use of 3 or more closely spaced concentrations, carefully selected to yield up to 50% toxicity, allowed detection of a positive response at a single harvest time for all 7 chemicals. [Bean CL et al; Mutat Res 265 (1): 31-44 (1992)]**PEER REVIEWED** The effects of phenolic dental medicaments on lipoxygenase activities of rat dental pulp and human platelets were studied. The major product derived from (14)C arachidonic acid by the homogenate of rat dental pulp was 12-hydroxyeicosatetraenoic acid (15hydroxyeicosatetraenoic acid). Eugenol and p-chlorophenol dose dependently inhibited hydroxyeicosatetraenoic acids formation. The IC50 values of eugenol and pchlorophenol were 0.62 and 0.34 mM respectively. The concentrations of these compounds that inhibit lipoxygenase were similar to those required to inhibit cyclooxygenase. These compounds also inhibited 12-lipoxygenase of human platelets with a similar range of concentrations. The results show that phenolic dental medicaments inhibit pulpal and platelet lipoxygenase. Thus, inhibition of arachidonic acid metabolism by phenolic dental medicaments via the lipoxygenase pathway may be involved in the analgesic and anti-inflammatory effects of the medicaments in endodontic therapy. [Dohi T et al; Dent Jpn (Tokyo) 27 (1): 45-9 (1990)]**PEER REVIEWED** Eugenol is widely used as a food flavoring agent and a dental analgesic. Mice treated with eugenol (400-600 mg/kg, orally) in combination with an inhibitor of glutathione synthesis, buthionine sulfoximine (1 hr before eugenol, 4 mmol/kg, ip) developed hepatotoxicity characterized by increases in relative liver weight and serum glutamicpyruvic transaminase, hepatic congestion, and centrilobular necrosis of hepatocytes. Eugenol (up to 600 mg/kg) alone produced no hepatotoxicity. Drug metabolism inhibitors such as carbon disulfide, methoxsalen, and piperonyl butoxide prevented or significantly reduced the hepatotoxic effect of eugenol given in combination with buthionine sulfoximine. On the other hand, pretreatment with phenobarbital increased the hepatotoxicity. These results suggest that eugenol is activated by a cytochrome p450 dependent metabolic reaction and that the liver injury is caused by inadequate rates of detoxification of the resulting metabolite in mice depleted of hepatic glutathione by buthionine sulfoximine treatment. [Mizutani T et al; Res Commun Chem Pathol Pharmacol 71 (2): 219-30 (1991)]**PEER REVIEWED** The local lymph node assay is a novel predictive test for the identification of contact allergens. The collaborative study reported here was performed to evaluate the reliability of the method when performed in independent laboratories. Eight chemicals were examined in each of 4 participating laboratories and results compared with predictions of skin sensitizing activity made from concurrent Magnusson and Kligman guinea pig maximization tests performed in a single laboratory. The local lymph node assay has as its theoretical basis the fact that contact allergens induce T-lymphocyte proliferative responses. In practice, predictions of contact sensitizing potential are made following measurement of proliferation in lymph nodes draining the site of exposure to chemical, and derivation of a stimulation index using control values as the comparator. Although in the present study there was some variation between laboratories with respect to the absolute stimulation indices recorded, it was found that with all chemicals each laboratory made the same predictions of sensitizing activity. Six chemicals (2,4dinitrochlorobenzene, formalin, eugenol, isoeugenol, p-phenylenediamine and potassium dichromate) yielded positive responses, and two (methyl salicylate and benzocaine) were negative, in each laboratory. Furthermore, with 7 of the 8 chemicals tested there was no significant difference between laboratories in terms of the characteristics of the doseresponse relationships recorded. With the exception of one chemical (benzocaine), predictions made with the local lymph node assay were in accord with those derived from guinea pig maximization tests. These inter-laboratory comparisons demonstrate that the local lymph node assay is a robust and reliable method for the identification of at least moderate and strong contact allergens. [Kimber I et al; Toxicol Lett 55 (2): 203-13 (1991)]**PEER REVIEWED** The naturally occurring alkenylbenzene, eugenol, was examined for its ability to form DNA adducts in the livers of mice that had been treated with up to 10 mg of the compound. No adducts were detected by (32)P postlabelling with a limit of detection of 1 adduct in 1X10+9 nucleotides. Under these conditions adducts were readily detected in liver DNA from the structurally related hepatocarcinogen safrole. [Phillips DH; Mutat Res 245 (1): 23-6 (1990)]**PEER REVIEWED** Eugenol, previously found to behave as a genotoxin in in vitro systems and as a noncarcinogen in rodents, was evaluated for its ability to induce genotoxic effects in vivo. Rats were given by gavage a single or two successive doses equal to one-half the corresponding LD50, killed at different times after treatment, and examined for the following end points: the frequency of both micronucleated polychromatic erythrocytes in the bone marrow and micronucleated hepatocytes (after partial hepatectomy), the in vivo-in vitro induction of DNA fragmentation, as measured by the alkaline elution technique, and of unscheduled DNA synthesis, as measured by autoradiography, in hepatocyte primary cultures. The two latter end points were also evaluated after in vitro exposure of hepatocytes to log-spaced subtoxic concentrations. Eugenol never produced effects indicative of genotoxic activity. [Allavena A et al; Teratog Carcinog Mutagen 12 (1): 31-41 (1992)]**PEER REVIEWED** Eugenol produces hepatic injury in mice depleted of glutathione by pretreatment with buthionine sulfoximine. Several eugenol analogs were examined for their ability to cause hepatic injury after administration to mice in combination with buthionine sulfoximine. Hepatotoxicity was assessed by measuring relative liver weight, liver blood volume, and serum glutamic-pyruvic transaminase activity in mice. Comparison of the treated compounds showed that the structural requirements for toxic potency was a phenolic ring having an allyl substituent at the 4-position. These structural requirements can be explained by assuming that a vinylogous quinone methide formed by metabolic oxidation of eugenol plays a role in inducing hepatotoxicity in glutathione depleted mice. [Mizutani T et al; Res Commun Chem Pathol Pharmacol 73 (1): 87-96 (1991)]**PEER REVIEWED** Eugenol, an extract of cloves, has been associated with pulmonary edema when inhaled from commercially available clove cigarettes. The hypothesis that eugenol directly causes lung edema through oxidant mediated mechanisms was tested by infusing eugenol (0.1 and 1.0 mM) into isolated rabbit lungs perfused with a cell free albumin and physiologic salt solution. Lung edema (1.0 mM) was observed as demonstrated by increased lung weight gain and wet to dry lung weight ratios without alterations in mean pulmonary artery pressure. The oxygen metabolite scavengers catalase (1,000 unit/ml) and dimethylthiourea (30 mM) attenuated lung edema. Instillation of dimethylurea, superoxide dismutase, or heat-inactivated catalase did not prevent lung edema formation. It was concluded that eugenol causes lung edema in isolated lungs through oxidant mediated mechanisms in the absence of circulating formed blood elements.

Animals were given 3 sc injections of 1,2- dimethylhydrazine at a dose of 40 mg/kg body weight within 1 wk and then were injected with 1-methyl-1-nitrosourea ip at a dose of 20 mg/kg body weight 2 times per wk for 2 wk. Thereafter, the were maintained on a diet containing either 0.2% beta-carotene, 2 ppm selenium, 1% ferulic acid, 1% esculin or 0.8% eugenol. At week 52 surviving rats were killed and complete histological examinations were performed. Administration of eugenol enhanced the development of both hyperplasia and papillomas in the forestomach. Eugenol decreased the incidence of kidney nephroblastomas. The results thus showed that eugenol exerts promoting activity for forestomach carcinogenesis while the other antioxidants might have weak organ specific inhibitory effects under these experimental conditions.

However, they are not bacterial mutagens in the Ames test. The ability of a series of carcinogenic and non-carcinogenic congeners to induce unscheduled DNA synthesis was studied in freshly isolated rat hepatocytes in primary culture. The cytotoxicity of these compounds was assessed by lactate dehydrogenase leakage. Eugenol, for which evidence of carcinogenicity is equivocal or negative, did not induce unscheduled DNA synthesis. All compounds were markedly cytotoxic at concentrations between 1X10-3 and 1X10-2 M, irrespective of their structural features. [Howes AJ et al; Food Chem Toxicol 28 (8): 537-42 (1990)]**PEER REVIEWED** A study was conducted in male Fischer rats to assess the effect of dietary administration of eugenol on the activities of liver detoxifying enzymes, specifically, uridine diphosphate glucuronyltransferase, uridine diphosphate glucose dehydrogenase, and glutathione-S-transferase. Groups of rats were given diets containing 0, 1, 3, or 5% by weight eugenol for 22 days; in long term experiments lasting 23 wk, one group of rats received control diet and another group was alternatively fed the above named concentrations of eugenol. The activities of uridine diphosphate glucuronyltransferase in liver microsomes were tested of 1-naphthol, 4-nitrophenol, 4-hydroxybiphenyl, 4methylumbelliferone, and bilirubin as substrates. The activities of uridine diphosphate glucose dehydrogenase and glutathione-S-transferase were tested using liver cytosol. The activities of liver microsomal uridine diphosphate glucuronyltransferase toward 1naphthol, 4- nitrophenol, 4-hydroxybiphenyl, and 4-methylumbelliferone were enhanced by dietary administration of eugenol; activity on bilirubin was almost unchanged. Similar results for uridine diphosphate glucose dehydrogenase and glutathione-S-transferase activities in liver cytosol were obtained by dietary administration of eugenol. Glutathione-S-transferase activities toward 1-chloro-2,4-dinitrobenzene and 1,2-dichloro4-nitrobenzene were increased markedly by dietary administration of eugenol. All enhancements of enzyme activities were related to the dietary level of eugenol. The content of cytochrome p450 in liver microsomes was not increased during the 13 wk period. No significant change in gamma-glutamyl transpeptidase, a marker for chemical carcinogenesis, was noted. It was concluded that eugenol may be a safe and nontoxic inhibitor of carcinogenesis.

V36 86 (1985)]**PEER REVIEWED** The metabolism and toxic effects of eugenol were studied in isolated rat hepatocytes. Incubation of hepatocytes with eugenol resulted in the formation of conjugates with sulfate, glucuronic acid and glutathione. The major metabolite formed was the glucuronic acid conjugate. Covalent binding to cellular protein was observed using (3)H eugenol. Loss of intracellular glutathione and cell death were also observed in these incubations. Concentrations of 1 mM eugenol caused a loss of over 90% of intracellular glutathione and resulted in approximately 85% cell death over a 5 hr incubation period. The loss of the majority of glutathione occurred prior to the onset of cell death (2 hr). The effects of eugenol were concentration dependent. The addition of 1 mM N-acetylcysteine to incubations containing 1 mM eugenol was able to completely prevent glutathione loss and cell death as well as inhibit the covalent binding of eugenol metabolites to protein. Conversely, pretreatment of hepatocytes with diethylmaleate to deplete intracellular glutathione increased the cytotoxic effects of eugenol. These results demonstrate that eugenol is actively metabolized in hepatocytes and suggest that the cytotoxic effects of eugenol are due to the formation of a reactiv intermediate, possibly a quinone methide.
