| Wechselwirkungen | 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 glutamic-pyruvic 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.The present study was undertaken to evaluate the chemopreventive potential of eugenol alone and in combination with a chemotherapeutic agent such as gemcitabine. Eugenol showed dose-dependent selective cytotoxicity toward HeLa cells in comparison to normal cells, pointing to its safe cytotoxicity profile. A combination of eugenol and gemcitabine induced growth inhibition and apoptosis at lower concentrations, compared with the individual drugs. The analysis of the data using a combination index showed combination index values of <1 indicating strong synergistic interaction. The combination thus may enhance the efficacy of gemcitabine at lower doses and minimize the toxicity on normal cells. In addition, the expression analysis of genes involved in apoptosis and inflammation revealed significant downregulation of Bcl-2, COX-2, and IL-1beta on treatment with eugenol. Thus, the results suggest that eugenol exerts its anticancer activities via apoptosis induction and anti-inflammatory properties and also provide the first evidence demonstrating synergism between eugenol and gemcitabine, which may enhance the therapeutic index of prevention and/or treatment of cervical cancer.The biochemical mechanisms underlying the increased toxicity of several plant essential oils (thymol, eugenol, pulegone, terpineol, and citronellal) against fourth instar of Aedes aegypti L. when exposed simultaneously with piperonyl butoxide (PBO) were examined. Whole body biotransformational enzyme activities including cytochrome P450-mediated oxidation (ethoxyresorufin O-dethylase (EROD)), glutathione S-transferase (GST), and beta-esterase activity were measured in control, essential oil-exposed only (single chemical), and essential oil + PBO (10 mg/liter) exposed larvae. At high concentrations, thymol, eugenol, pulegone, and citronellal alone reduced EROD activity by 5-25% 16 h postexposure. Terpineol at 10 mg/liter increased EROD activity by 5 +/- 1.8% over controls. The essential oils alone reduced GST activity by 3-20% but PBO exposure alone did not significantly affect the activity of any of the measured enzymes. All essential oils in combination with PBO reduced EROD activity by 58-76% and reduced GST activity by 3-85% at 16 hr postexposure. This study indicates a synergistic interaction between essential oils and PBO in inhibiting the cytochrome P450 and GST detoxification enzymes in Ae. aegypti.... Swiss albino mice were administered different doses of eugenol (75,150 and 300 mg/kg) before exposure to 1.5 Gy of gamma radiation. The micronucleus test was carried out to determine the genetic damage in bone marrow. Our results demonstrated significant reduction in the frequencies of micronucleated polychromatic erythrocytes (MnPCEs) with all three eugenol doses. Eugenol (150 mg/kg) was also tested against different doses of radiation (0.5, 1, 1.5, and 2 Gy) and was found to afford significant radioprotection. Reduction in the incidence of MnPCEs could be noticed up to 72 hr postirradiation (1.5 Gy). Moreover, the level of peroxidative damage and the specific activities of lactate dehydrogenase (LDH) and methylglyoxalase I (Gly I) were observed in the liver of mice treated with eugenol for seven days in comparison to untreated mice.For more Interactions (Complete) data for EUGENOL (7 total), please visit the HSDB record page. |
| Hepatotoxicity | The low concentrations of eugenol and clove extracts used topically and in herbal products have not been convincingly linked to instances of liver injury, either in the form of serum enzyme elevations or clinically apparent liver injury. In high doses, however, eugenol appears to be a direct cytotoxin and several instances of severe acute liver and kidney injury have been reported after accidental overdose of eugenol containing herbal products, largely in children. Overdoses have been marked by the onset of agitation, decrease in consciousness and coma arising within hours on ingestion (10-30 mL of clove oil). There is typically an accompanying acidosis, respiratory depression and severe hypoglycemia requiring ventilation and intravenous glucose. Liver injury arises 12 to 24 hours after ingestion with marked elevations in serum aminotransferase levels and early coagulation abnormalities. Signs of hepatic failure arise rapidly, and jaundice can develop and deepen. The overall clinical presentation is typical of acute hepatic necrosis and similar to that of acetaminophen, iron or copper overdose. The liver injury generally worsens for several days but then rapidly improves and ultimately resolves within 1 to 3 weeks. Renal dysfunction may also occur but rarely requires intervention or dialysis. Long term injury or effects have not been described. Cases described in the literature have been in infants who swallowed clove oil being used by parents. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 340(SRC), determined from a log Kow of 2.49(2) and a regression-derived equation(3), indicates that eugenol is expected to have moderate mobility in soil(SRC). Volatilization of eugenol from moist soil surfaces is expected to occur(SRC) given a an estimated Henry's Law constant of 1.92X10-6 atm-cu m/mole(SRC), estimated from its vapor pressure, 0.0221 mm Hg at 25 °C(4), and water solubility, 2460 mg/L(5). A theoretical model of soil volatilization predicts that 4-33% of eugenol applied to a soil surface will volatilize during the first 10 days(6)the fastest volatilization rates occur with lowest soil organic content and moisture content(6). Isoeugenol, which is structurally similar to eugenol, was found to be readily biodegradable using a Manometric Respirometry Test in which isoeugenol reached 79% biodegradation after 28 days(7)by analogy, eugenol may also be readily biodegradable(SRC). Eugenol absorbs uv light at wavelengths >290 nm(8), and therefore may be susceptible to direct photolysis on soil surfaces exposed to sunlight(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 340(SRC), determined from a log Kow of 2.49(2) and a regression-derived equation(3), indicates that eugenol is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected to occur slowly(4) based upon an estimated Henry's Law constant of 1.92X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 0.0221 mm Hg at 25 °C(5), and water solubility, 2460 mg/L(6). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 25 and 183 days, respectively(SRC). According to a classification scheme(7), an estimated BCF of 20(SRC), from its log Kow and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Eugenol is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(4). Eugenol absorbs UV light at wavelengths >290 nm(8), and therefore may be susceptible to direct photolysis by sunlight in water(SRC). Isoeugenol, which is structurally similar to eugenol, was found to be readily biodegradable using a Manometric Respirometry Test (OECD Guideline 301F) in which isoeugenol reached 79% biodegradation after 28 days(9)by analogy, eugenol may also be readily biodegradable(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), eugenol, which has a vapor pressure of 0.0221 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase eugenol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 5.9 hours(SRC), calculated from its rate constant of 6.5X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Vapor-phase eugenol is also degraded in the atmosphere by reaction with ozone(SRC)the half-life for this reaction in air is estimated to be 23 hours(SRC), calculated from its rate constant of 1.2X10-17 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Eugenol absorbs UV light at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). Irradiation of eugenol in methanol solution yields 4-cyclopropyl-2-methoxyphenol as the main photodegradation product(5)sunlight degrades the main constituents of essential oils(5). |

Beschreibung
Sensitization to eugenol mainly occurs in those in dental professions. Eugenol is contained in the "fragrance mix".
Occurrence
Reported found as a constituent in several volatile oils: clove oil, laurel and cinnamon leaf oil. Smaller amounts of eugenol are also present in the oil of camphor, Java citronella, California laurel and acacia flowers; remarkable amounts of eugenol are found in Ocimum sanctum (70%) and Ocimum gratissimum (60%). Eugenol is also found in the oil from violet flowers (21%); in some plants, eugenol probably occurs as glucoside. Reported found in apricot, citrus oils, raspberry, strawberry, tomato, anise, cinnamon (leaf, bark and roots), clove bud and stem, nutmeg, mace, pepper, smoked fish, beer, whiskey, grape wines, cocoa, mango, tarragon, laurel, myrtle leaf, and pimento berry and leaf.
Verwenden
Eugenol is a dental compound which shows cytotoxicity to human oral squamous cell carcinoma and oral cells. When glucosylated, this compound exhibits anti-inflammatory activity.
Herstellung & Synthese
synthetische
Since sufficient eugenol can be isolated from cheap essential oils, synthesis is not industrially important. Eugenol is still preferentially isolated from clove leaf and cinnamon leaf oil (e.g., by extraction with sodium hydroxide solution). Nonphenolic materials are then removed by steam distillation. After the alkaline solution is acidified at low temperature, pure eugenol is obtained by distillation.
