| 상호 작용 | In recent years, considerable efforts have been made to identify new chemopreventive agents which could be useful for man. Myrica nagi, a subtropical shrub, has been shown to possess significant activity against hepatotoxicity and other pharmacological and physiological disorders. We have shown a chemopreventive effect of Myrica nagi on cumene hydroperoxide-induced cutaneous oxidative stress and toxicity in mice. Cumene hydroperoxide treatment at a dose level of 30 mg/animal/0.2 mL acetone enhances susceptibility of cutaneous microsomal membrane for iron-ascorbate-induced lipid peroxidation and induction of xanthine oxidase activity which are accompanied by decrease in the activities of cutaneous antioxidant enzymes such as catalase, glutathione peroxidase, glutathione reductase, glucose-6-phosphate dehydrogenase and depletion in the level of cutaneous glutathione. Parallel to these changes a sharp decrease in the activities of phase II metabolizing enzymes such as glutathione S-transferase and quinone reductase has been observed. Application of Myrica nagi at doses of 2.0 mg and 4.0 mg/kg body weight in acetone prior to that of cumene hydroperoxide (30 mg/animal/0.2 mL acetone) treatment resulted in significant inhibition of cumene hydroperoxide-induced cutaneous oxidative stress and toxicity in a dose-dependent manner. Enhanced susceptibility of cutaneous microsomal membrane for lipid peroxidation induced by iron ascorbate and xanthine oxidase activities were significantly reduced (p<0.05). In addition the depleted level of glutathione, the inhibited activities of antioxidants, and phase II metabolizing enzymes were recovered to a significant level (p<0.05). The protective effect of Myrica nagi was dose-dependent. In summary our data suggest that Myrica nagi is an effective chemopreventive agent in skin and capable of ameliorating cumene hydroperoxide-induced cutaneous oxidative stress and toxicity.In the present study, we evaluated the sensitivity of different Escherichia coli strains to Cumene hydroperoxide (CHP) treatment under distinct conditions of Fe2+ availability. Our results showed that the pretreatment with an iron chelator (dipyridyl) protects all the tested strains against CHP toxic effects, but it was not sufficient to abolish the CHP induced mutagenesis. On the other hand, simultaneous pretreatment with both dipyridyl and neocuproine (copper chelator) leads to a complete protection against CHP mutagenic effects. Our data suggest the participation of copper ion in the CHP mutagenesis induced in E. coli.Organic peroxides are widely used in the chemical industry as initiators of oxidation for the production of polymers and fiber-reinforced plastics, in the manufacture of polyester resin coatings, and pharmaceuticals. Free radical production is considered to be one of the key factors contributing to skin tumor promotion by organic peroxides. In vitro experiments have demonstrated metal-catalyzed formation of alkoxyl, alkyl, and aryl radicals in keratinocytes incubated with cumene hydroperoxide. The present study investigated in vivo free radical generation in lipid extracts of mouse skin exposed to cumene hydroperoxide. The electron spin resonance (ESR) spin-trapping technique was used to detect the formation of alpha-phenyl-N-tert-butylnitrone (PBN) radical adducts, following intradermal injection of 180 mg/kg PBN. It was found that 30 min after topical exposure, cumene hydroperoxide (12 mmol/kg) induced free radical generation in the skin of female Balb/c mice kept for 10 weeks on vitamin E-deficient diets. In contrast, hardly discernible radical adducts were detected when cumene hydroperoxide was applied to the skin of mice fed a vitamin E-sufficient diet. Importantly, total antioxidant reserve and levels of GSH, ascorbate, and vitamin E decreased 34%, 46.5%. 27%, and 98%, respectively, after mice were kept for 10 weeks on vitamin E-deficient diet. PBN adducts detected by ESR in vitamin E-deficient mice provide direct evidence for in vivo free radical generation in the skin after exposure to cumene hydroperoxide.Hemidesmus indicus has been shown to possess significant activity against immunotoxicity and other pharmacological and physiological disorders. In this communication, we have shown the modulating effect of H. indicus on cumene hydroperoxide-mediated cutaneous oxidative stress and tumor promotion response in murine skin. Cumene hydroperoxide treatment (30 mg per animal) increased cutaneous microsomal lipid peroxidation and induction of xanthine oxidase activity which are accompanied by decrease in the activities of cutaneous antioxidant enzymes and depletion in the level of glutathione. Parallel to these changes a sharp decrease in the activities of phase II metabolizing enzymes was observed. Cumene hydroperoxide treatment also induced the ornithine decarboxylase activity and enhanced the [(3)H]-thymidine uptake in DNA synthesis in murine skin. Application of ethanolic extract of H. indicus at a dose level of 1.5 and 3.0 mg/kg body weight in acetone prior to that of cumene hydroperoxide treatment resulted in significant inhibition of cumene hydroperoxide-induced cutaneous oxidative stress, epidermal ornithine decarboxylase activity and enhanced DNA synthesis in a dose-dependent manner. Enhanced susceptibility of cutaneous microsomal membrane for lipid peroxidation and xanthine oxidase activity were significantly reduced (p<0.01). In addition the depleted level of glutathione, inhibited activities of antioxidants and phase II metabolizing enzymes were recovered to significant level (p<0.05). In summary, our data suggest that H. indicus is an effective chemopreventive agent in skin and capable of ameliorating hydroperoxide-induced cutaneous oxidative stress and tumor promotion.For more Interactions (Complete) data for Cumene hydroperoxide (12 total), please visit the HSDB record page. |

| 환경 거동 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 2000(SRC), determined from a structure estimation method(2), indicates that cumene hydroperoxide is expected to have low mobility in soil(SRC). Volatilization of cumene hydroperoxide from moist soil surfaces is not expected(SRC) given an estimated Henry's Law constant of 4.7X10-8 atm-cu m/mole(SRC), based upon its vapor pressure, 3.27X10-3 mm Hg(3), and water solubility, 13,900 mg/L(4). Cumene hydroperoxide is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). A 0% of Theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation is not an important environmental fate process in soil(SRC). However, hydroperoxides react with a variety of compounds and are reduced readily to the corresponding alcohols(6). They are decomposed readily by multivalent metal ions, are photo- and thermally-sensitive and undergo initial oxygen-oxygen bond homolysis, and they are readily attacked by free radicals, undergoing induced and self-induced decomposition(6). Therefore, chemical degradation is expected to be the dominant fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 2000(SRC), determined from a structure estimation method(2), indicates that cumene hydroperoxide is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 4.7X10-8 atm-cu m/mole(SRC), derived from its vapor pressure, 3.27X10-3 mm Hg(4), and water solubility, 13,900 mg/L(5). According to a classification scheme(6), an estimated BCF of 12(SRC), from an estimated log Kow of 2.16(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low. Biodegradation in water is not expected based on a 0% biodegradation using the Japanese MITI test(7). However, hydroperoxides react with a variety of compounds and are reduced readily to the corresponding alcohols(8). They are decomposed readily by multivalent metal ions, are photo- and thermally sensitive and undergo initial oxygen-oxygen bond homolysis, and they are readily attacked by free radicals, undergoing induced and self-induced decomposition(8). Therefore, chemical degradation is expected to be the dominant fate process in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), cumene hydroperoxide, which has a vapor pressure of 3.27X10-3 mm Hg at 25 °C(2), is expected to exist solely in the vapor-phase in the ambient atmosphere. Vapor-phase cumene hydroperoxide 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 45 hours(SRC), calculated from its rate constant of 8.6X10-12 cu cm/molecule-sec at 25 °C(SRC) determined using a structure estimation method(3). Cumene hydroperoxide absorbs light in the environmental spectrum and has the potential for direct photolysis(4). |

| 독성 요약 | IDENTIFICATION AND USE: Cumene peroxide is a colorless to pale-yellow liquid. It is used in production of acetone and phenolas polymerization catalyst, particularly in the redox systems, used for rapid polymerization. HUMAN STUDIES: Normal human epidermal keratinocytes undergo profound lipid oxidation with preference for phosphatidylserine followed by phosphatidylserine externalization upon exposure to cumene hydroperoxide. ANIMAL STUDIES: Application of 1-2 drops of cumene hydroperoxide (73%) to rabbit skin (circular area, 2 cm diameter) produced erythema, edema, and vesiculation within 2-3 days. 1 mg applied to the eye of rabbits caused redness of palpebral conjunctiva and chemosis. Skin carcinoma formed in DMBA/cumene peroxide-exposed mice in initiation/promotion study. Mutagenic activity of cumene hydroperoxide was observed in the Drosophila melanogaster test. Cumene hydroperoxide was evaluated for mutagenicity in the Salmonella microsome preincubation assay. Cumene hydroperoxide was tested in as many as 5 Salmonella typhimurium strains (TA1535, TA1537, TA97, TA98, and TA100) in the presence and absence of metabolic activation. Cumene hydroperoxide was positive in the Ames test with the last positive dose tested 33 ug/plate. ECOTOXICITY STUDIES: Toxic action of water pollutants was tested by measuring the immobilization of Daphnia magna, strain ircha. The mean effective concentration (EC50) for cumene hydroperoxide was less than 10 mg/L. |
| 생태독성 발췌 | /AQUATIC SPECIES/ The toxicity threshold for Uronema parduczi was less than 1 mg/L for cumene hydroperoxide./OTHER TERRESTRIAL SPECIES/ Organic pollutants effects on lichens have not been addressed. Rehydration is critical for lichens, a burst of free radicals involving NO occurs. Repeated dehydrations with organic pollutants could increase oxidative damage. Our aim is to learn the effects of cumene hydroperoxide (CP) during lichen rehydration using Ramalina farinacea (L.) Ach., its photobiont Trebouxia spp. and Asterochloris erici. Confocal imaging shows intracellular ROS and NO production within myco and phycobionts, being the chloroplast the main source of free radicals. CP increases ROS, NO and lipid peroxidation and reduces chlorophyll autofluorescence, although photosynthesis remains unaffected. Concomitant NO inhibition provokes a generalized increase of ROS and a decrease in photosynthesis. Our results suggest that CP induces a compensatory hormetic response in Ramalina farinacea that could reduce the lichen's antioxidant resources after repeated desiccation-rehydration cycles. NO is important in the protection from CP./OTHER TERRESTRIAL SPECIES/ Lepidopteran insect cells serve as excellent model to study stress responses and are known to display resistance against DNA-damaging agents including ionizing radiationhowever, limited information is available on the effects of membrane damaging agents in these cells. In this study, we investigated the response of Sf9 cells (derived from ovaries of Spodoptera frugiperdaorder Lepidoptera) to cumene hydroperoxide (CHPx), compared to human BMG-1 cells. CHPx treatment at doses lethal for human cells also caused typical necrosis in Sf9. Severe necrosis in human BMG-1 cells was observed at 125 uM, whereas similar effect in Sf9 cells was observed at 250 uM. In Sf9 cells, CHPx (250 uM) induced negligible changes in mitochondrial membrane potential and intracellular reactive oxygen species, while moderate effect was observed on intracellular calcium distribution. Reduced DNA damage and lipid (including cardiolipin) oxidation was observed in Sf9 cells that could be due to moderate total antioxidant status and constitutive/induced glutathione S-transferase activity. This study importantly demonstrates that Lepidopteran insect cells having extensive resistance towards DNA damaging agents show only moderately higher resistance to membrane damaging agents. A stronger reducing environment involving efficient antioxidant system seems to contribute significantly in this response. |

Testing status for cumene hydroperoxide is available.[Available from, as of November 3, 2017: https://ntpsearch.niehs.nih.gov/?e=True&ContentType=Testing+Status] |
| Effluent Concentrations | Cumene hydroperoxide may be emitted as an air pollutant from industrial sources that produce cyclic crudes and intermediates, and industrial organic chemicals(1). |
| ICSC Environmental Data | The substance is toxic to aquatic organisms. |
| Medical Surveillance | Initial Medical Screening: Employees should be screened for history of certain medical conditions which might place the employee at an increased risk. ... /Screen for/ eye, skin, and chronic respiratory diseases. /Hydrogen peroxide/ |
| RCRA 요건 | U096As stipulated in 40 CFR 261.33, when alpha,alpha-dimethylbenzylhydroperoxide, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5). |
| TSCA 요건 | Pursuant to section 8(d) of TSCA, EPA promulgated a model Health and Safety Data Reporting Rule. The section 8(d) model rule requires manufacturers, importers, and processors of listed chemical substances and mixtures to submit to EPA copies and lists of unpublished health and safety studies. Hydroperoxide, 1-methyl-1-phenylethyl- is included on this list. Effective date: 3/7/86Sunset date: 12/19/95. |
| 대기 기준 | This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Cumene hydroperoxide is produced, as an intermediate or a final product, by process units covered under this subpart. |
| CERCLA 보고 수량 | Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 10 lb or 4.54 kg. The toll free number of the NRC is (800) 424-8802. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV.D.3.b). |
