| 체내 부담 | 2-Phenylethylamine is an endogenous amine related structurally to amphetamine(1)it is found in normal human urine at a concentration of about 30 ug/L(1). |
| 상호 작용 | The effects of chronic administration of antidepressant drugs and 2-phenylethylamine on beta-adrenoceptor function were assessed. Monoamine oxidase inhibitors [phenelzine sulfate, 5 or 10 mg/kg per day, and (-)-deprenyl HCl, 1 mg/kg per day] and 2-phenylethylamine HCl (10 mg/kg per day) were administered to male Sprague-Dawley rats via Alzet osmotic minipumps. On days 21 and 22, the motor-suppressant actions of the beta-adrenoceptor agonist salbutamol hemisulfate (3 mg/kg intraperitoneally after 15 min) were assessed as a measure of beta-adrenoceptor sensitivity. On day 28, the animals were killed, and their brains were used for the measurement of monoamine oxidase activity and concentrations of 2-phenylethylamine, an endogenous amine and a metabolite of phenelzine. Phenelzine sulfate at 10 mg/kg per day (but not 5 mg/kg per day) and the combination of (-)-deprenyl and 2-phenylethylamine resulted in a decrease in the response to salbutamol. These treatments also resulted in substantial increases in brain 2-phenylethylamine concentrations. The phenelzine treatments each resulted in an equivalent inhibition of brain monoamine oxidase activity. These results support the proposal that 2-phenylethylamine may, at least in part, mediate the effects of phenelzine on beta-adrenoceptor function.Systemic administration of beta-phenylethylamine caused behavioral syndrome in rats consistent with activation of 5-HT receptors in CNS. Redection of endogenous 5-HT levels did not prevent syndrome. 5-HT receptor antagonists, methysergide and mianserine, blocked effects of beta-phenylethylamine. Beta-phenylethylamine produces serotonergic effects by direct 5-ht agonist action.In rats, beta-phenylethylamine (50-100 mg/gk, ip) induced stereotypic behavior and disrupted polyribosomes. Haloperidol and chlorpromazine antagonized these effects.The cerebrovascular actions of phenylethylamine, an amine that has been implicated in the pathogenesis of migraine, were investigated in 16 anesthetized baboons. The influence of monoaminergic blocking agents and of a specific inhibitor of monoamine oxidase upon the cerebral circulatory and metabolic actions of phenylethylamine were examined. The reductions in cerebral blood flow (28 percent) and cerebral oxygen consumption (31 percent) that accompany the intracarotid administration of phenylethylamine (2 X 10(-6) moles per kilogram per minute) were unaffected by the prior administration of either phenoxybenzamine (1.5 mg/kg, IV) or pimozide (0.5 mg/kg, IV). The administration of phenoxybenzamine and pimozide per se did not significantly disturb cerebral blood flow or oxygen consumption. The ability of migraine patients to oxidatively deaminate phenylethylamine is reduced at the time of their attacks. In the present experiments, the administration of the monoamine oxidase type B inhibitor, deprenyl (1 mg/kg, IV), did not effect significant changes in cerebral blood flow or cerebral oxygen consumption. However, following deprenyl, the administration of phenylethylamine (4 X 10(-8) moles per kilogram per minute), a concentration which was without effect in normal animals, significantly reduced cerebral blood flow. Some of the possible mechanisms influencing the sensitivity of the cerebral circulation to phenylethylamine, and their relationship to migraine, are considered.For more Interactions (Complete) data for 2-Phenylethylamine (9 total), please visit the HSDB record page. |
| 환경 거동 | TERRESTRIAL FATE: Based on a classification scheme(1), a calculated Koc value of 120(SRC), determined from an experimental soil-water distribution coefficient(2), indicates that 2-phenylethylamine is expected to have high mobility in soil(SRC). The pKa of 2-phenylethylamine is 9.83(3), indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of the cation from moist soil is not expected because cations do not volatilize(SRC). 2-Phenylethylamine is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.23 mm Hg at 20 °C(5). A 58% of Theoretical BOD using activated sludge in the Japanese MITI test(6) suggests that biodegradation is an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), a Koc value of 120(SRC), determined from an experimental soil-water distribution coefficient(2), indicates that 2-phenylethylamine is expected to adsorb to suspended solids and sediment(SRC). A pKa of 9.83(3) indicates 2-phenylethylamine will exist almost entirely in the cation form at pH values of 5 to 9 and, therefore, volatilization from water surfaces is not expected to be an important fate process(SRC). 2-Phenylethylamine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(4). According to a classification scheme(5), an estimated BCF of 4(SRC), from its log Kow of 1.41(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low. Utilizing the Japanese MITI test, 58% of the Theoretical BOD was reached in 2 weeks(8) indicating that biodegradation may be an important environmental fate process(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-phenylethylamine, which has a vapor pressure of 0.23 mm Hg at 20 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-phenylethylamine 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 10 hours(SRC), calculated from its rate constant of 3.8X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). 2-Phenylethylamine does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). |

| 독성 요약 | IDENTIFICATION AND USE: 2-Phenylethylamine (PEA) is a colorless to slightly yellow liquid with fishy odor. It is used in organic synthesis, as a laboratory reagent, and in scintillation counters (CO2 absorber). HUMAN STUDIES: PEA poisonings may be severe in young and healthy individuals. The most frequently reported symptoms included anxiety and hallucinations (49%), mydriasis and headache (41%), tachycardia (40%) and hypertension (15%). Complications such as seizures (7%), cardiac arrest (5%), toxic myocarditis (1%) and hemorrhagic stroke (1%) were also observed. PEA was teratogenic at concentrations observed in individuals with phenylketonuria (PKU). ANIMAL STUDIES: Behavioral effects of PEA an agent proposed to act on both 5-HT and dopaminergic brain mechanisms, was examined in Wistar, Sprague-Dawley, and Long-Evans rats. Behavioral components assessed included: forepaw padding, headweaving, and splayed hindlimbs, which are thought to be indicative of central 5-HT stimulation. Following injection of 50 mg/kg Wistar rats were more active and reactive than Long-Evans or Sprague-Dawley rats. There was a significant difference in response to stimulation of central monaminergic mechanisms between Wistar rats and rats of the Long-Evans and Sprague-Dawley strains. The behavioral consequences of daily PEA administration for a period of 6 weeks have been examined. Rats showed signs of the 5-HT behavioral syndrome after a single injection of PEA (50 mg/kg) or 7 daily injections of PEA (25 mg/kg). The syndrome reached peak intensity after 3 weeks treatment. PEA reduced 24-hr food intake after a single injection in male rats and tolerance to this effect did not develop during 4-wk treatment. PEA caused a dose-dependent reduction in body wt gain during this period. The anorectic effect of PEA appears to be behaviorally specific to feeding, since there was no concurrent inhibition of water intake or diuresis. PEA induced myoclonic contractions in the submandibular muscle and epileptiform myoclonic spike discharges in electrocortical recording in anesthetized rats. PEA-induced stereotypy in rodents is suggested to model psychotic symptoms of schizophrenia. PEA is metabolized to azoxy-2-phenylethane (a mutagen). Exposure of D9 (neurulating) mouse embryos to PEA levels ranging from 0.01 to 1 mM for 24 hours in whole embryo culture results in 0% with neural tube closure defects at 0.01 mM and 67% at 0.1 mM and failure to thrive at 1 mM. Histological analysis also shows an increase in cell death in the neuroepithelium of embryos exposed to 0.1 and 1 mM PEA. D8 (head fold) embryos exposed to 0.1 mM PEA exhibited neural tube closure defects (89%) and craniofacial abnormalities (67%) similar to D9's, and in addition 28% had improper looping of the heart. In conclusion, it appears that phenylalanine has a low teratogenic potential, whereas, its metabolites PEA causes malformations similar to those observed in PKU offspring. Also the head fold stage appears more sensitive than the period of neurulation. |
| Plant Concentrations | 2-Phenylethylamine is found in the seed of cacao (Theobroma cacao)(1). |
| Soil Adsorption/Mobility | The soil-water distribution coefficient (Kd) for 2-phenylethylamine was experimentally determined to be 2.1 in a silty-clay loam soil with an organic carbon content of 1.7%(1), which corresponds to a Koc value of 120(SRC). According to a classification scheme(2), this Koc value suggests that 2-phenylethylamine is expected to have high mobility in soil. The pKa of 2-phenylethylamine is 9.83(3), indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). |
| Natural Pollution Sources | 2-Phenylethylamine is found in human urine (about 30 ug/L)(1), in the oil of bitter almonds(1), in marine algae(2), in tobacco leaves(3), and seeds of cacao(4). |
| Human Toxicity Excerpts | /HUMAN EXPOSURE STUDIES/ The effect of 25 mg histamine, 25 mg tyramine and 5 mg phenylethylamine in apple juice on 27 healthy volunteers was studied using a randomized placebo-controlled double-blind procedure. No statistically significant effect was found with histamine and tyramine, but phenylethylamine produced headache, dizziness and discomfort in some volunteers. In a 2nd experiment the effect of 4 different wines (2 dl) containing naturally several biogenic amines in various amounts (histamine nd (not detectable) - 21 ppmtyramine 1-23 ppmphenylethylamine nd - 6 ppmputrescine 2-55 ppm) on 20 volunteers was recorded. The percentage of volunteers experiencing symptoms was of the same order of magnitude as in the 1st experiment. No correlation existed in this 2nd experiment between the occurrence of symptoms and the concentration of biogenic amines in the wine samples./CASE REPORTS/ OBJECTIVES: Over the last decade, use of phenethylamines has become increasingly prevalent. This study aimed to describe typical aspects of phenethylamine poisoning in order to better inform patient care. METHODS: Phenethylamine poisoning cases reported to the Poison Control Center of Angers, France, from January, 2007 to December, 2013 were examined. Clinical findings were examined in 105 patients, including phenethylamine used, symptoms and final outcome. Patients were predominantly male (80%), with mean age 26+/-8 years. RESULTS: MDMA (38%), amphetamine (18%) and methamphetamine (14%) were the most commonly reported. Synthetic cathinones (10%) and the 2C series (7%) were also found. Substances most commonly associated with phenethylamine poisoning were cannabis (27%), ethanol (20%) and cocaine (9%). The most frequently reported symptoms included anxiety and hallucinations (49%), mydriasis and headache (41%), tachycardia (40%) and hypertension (15%). Complications such as seizures (7%), cardiac arrest (5%), toxic myocarditis (1%) and hemorrhagic stroke (1%) were also observed. Of the cases, the Poison Severity Score was: null or low, 66%, moderate, 21%, severe or fatal, 13%. Of the patients, 77% received hospital care and 12.4% were admitted to an intensive care unit. Analytical confirmations were obtained for all severe cases. While 93% of patients recovered, there were 5 deaths and 2 patients presented with neurological sequelae. CONCLUSIONS: Phenethylamine poisonings may be severe in young and healthy individuals. Physicians, toxicologists and analysts should be aware of new phenethylamine consumption trends in order to inform management of patient care and to contribute to a more responsive drug policy. /Phenethylamines//BIOMONITORING/ Urinary excretion (24-hr) of beta-phenylethylamine (PEA), phenylacetic acid (PAA), phenylalanine (Phe), and p-tyrosine (Tyr), and plasma levels of PAA, Phe, and Tyr were examined in 18 normal children and 26 children diagnosed as having attention-deficit hyperactivity disorder (ADHD). The results indicated that urinary excretion (expressed per g of creatinine) of free and total PEA was significantly lower in the ADHD patients, and plasma levels of Phe and Tyr were also decreased in the ADHD subjects compared with the normal controls./OTHER TOXICITY INFORMATION/ While the cause of dopaminergic neuronal cell death in Parkinson's disease (PD) is not yet understood, many endogenous molecules have been implicated in its pathogenesis. beta-phenethylamine (beta-PEA), a component of various food items including chocolate and wine, is an endogenous molecule produced from phenylalanine in the brain. It has been reported recently that long-term administration of beta-PEA in rodents causes neurochemical and behavioral alterations similar to that produced by parkinsonian neurotoxins. The toxicity of beta-PEA has been linked to the production of hydroxyl radical ((.)OH) and the generation of oxidative stress in dopaminergic areas of the brain, and this may be mediated by inhibition of mitochondrial complex-I. Another significant observation is that administration of beta-PEA to rodents reduces striatal dopamine content and induces movement disorders similar to those of parkinsonian rodents. However, no reports are available on the extent of dopaminergic neuronal cell death after administration of beta-PEA. Based on the literature, we set out to establish beta-PEA as an endogenous molecule that potentially contributes to the progressive development of PD. The sequence of molecular events that could be responsible for dopaminergic neuronal cell death in PD by consumption of beta-PEA-containing foods is proposed here. Thus, long-term over-consumption of food items containing beta-PEA could be a neurological risk factor having significant pathological consequences. |
| Fish/Seafood Concentrations | 2-Phenylethylamine was detected in three commercial brands of anchovies immersed in oil at 0.2-2.0 mg/kg(1).
