| Wechselwirkungen | Acute lung injury is an inflammatory syndrome that increases the permeability of the blood-gas barrier, resulting in high morbidity and mortality. Despite intensive research, treatment options remain limited. /This study/ investigated the protective efficacy of tezosentan, a novel, dual endothelin receptor antagonist, in an experimental model of alpha-naphthylthiourea (ANTU)-induced acute lung injury in rats. ANTU was intraperitoneally (i.p.) injected into rats at a dose of 10 mg/kg. Tezosentan was injected 30 minutes before ANTU was subcutaneously (s.c.) injected at doses of 2, 10, or 30 mg/kg, 60 minutes before ANTU was injected at doses of 2, 10, or 30 mg/kg (i.p.), and 90 minutes before ANTU at a dose of 10 mg/kg (i.p.). Four hours later, the lung weight/body weight (LW/BW) ratio and pleural effusion (PE) were measured. When injected 30 minutes before ANTU at doses of 2, 10, or 30 mg/kg (s.c.), tezosentan had no effect on lung pathology. When injected 60 minutes before ANTU at doses of 2, 10, or 30 mg/kg (i.p.) or 90 minutes before ANTU (10 mg/kg, i.p.), tezosentan significantly decreased the PE/BW ratio and had a prophylactic effect on PE formation at all doses. Therefore, tezosentan may attenuate lung injury. Furthermore, its acute and inhibitory effects on fluid accumulation were more effective in the pleural cavity than in the interstitial compartment in this experimental model.This study was designed to investigate the possible participation of morphine in pulmonary edema induced by alpha-naphthylthiourea (ANTU), which is a well-known noxious chemical agent in the lung. Injection of ANTU (15 mg/kg i.p.) produced pulmonary edema as indicated by an increase in lung weight/body weight ratio and pleural effusion reaching a maximum within 4 hr in rat. Administration of morphine prior to ANTU significantly inhibited to pulmonary edema with a dose-dependent manner. The protective effect of morphine is prevented by peripheral opioid receptor antagonist, naloxone methiodide. ANTU-treated rats were shown positive by inducible nitric oxide synthase immunohistochemical staining. There was no staining in the control group. On the other hand, the degree of staining was markedly reduced in tissue sections by morphine. These results suggest that previous administration of subcutaneous morphine has preventive effect on ANTU-induced pulmonary inflammatory reaction and its effect mediated via peripheral opioid receptors. Application of naloxone with ANTU has no effect on the lung parameters indicating that endogenous opioids do not modulate ANTU-induced damage.Iodine or iodide given to animals 6 hours prior to ANTU affords significant protection, but neither is effective after exposure.... Pretreatment of mice with 4-ipomeanol produced tolerance to alpha-naphthylthiourea. ... /Dose not specified/.For more Interactions (Complete) data for ALPHA-NAPHTHYLTHIOUREA (11 total), please visit the HSDB record page. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 3600(SRC), determined from a structure estimation method(2), indicates that alpha-naphthylthiourea is expected to have slight mobility in soil(SRC). The pKa of alpha-naphthylthiourea is estimated as 9.47(3), indicating that this compound will exist partially in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of neutral alpha-naphthylthiourea from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 8.5X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). The ionic form of alpha-naphthylthiourea is not expected to volatilize because ions do not volatilize. alpha-Naphthylthiourea is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.1X10-6 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). Biodegradation data in soil were not available(SRC, 2014).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 3600(SRC), determined from a structure estimation method(2), indicates that alpha-naphthylthiourea is expected to adsorb to suspended solids and sediment(SRC). An estimated pKa of 9.47(3) indicates alpha-naphthylthiourea will exist partially in the anion form at pH values of 5 to 9 and, therefore, volatilization of the ionic form from water surfaces is not expected to be an important fate process(SRC). Volatilization of the neutral form from water surfaces is not expected(4) based upon an estimated Henry's Law constant of 8.5X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(5). The hydrolysis half-life for alpha-naphthylthiourea is 361 days based on a measured hydrolysis rate constant of 2.2X10-8 L/mol sec at pH 7 and 25 °C(6). According to a classification scheme(7), an estimated BCF of 5.7(SRC), from a log Kow of 1.65(8) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data in water were not available(SRC, 2014).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), alpha-naphthylthiourea, which has an estimated vapor pressure of 1.1X10-6 Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase alpha-naphthylthiourea 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 1.6 hours(SRC), calculated from its rate constant of 2.2X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2). Particulate-phase alpha-naphthylthiourea may be removed from the air by wet and dry deposition(SRC). alpha-Naphthylthiourea contains chromophores that absorb at wavelengths >290 nm(3) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). |

| Toxizitätsübersicht | IDENTIFICATION AND USE: Alpha-Naphthyl thiourea (ANTU) is a white, crystalline, or gray odorless powder with a bitter taste. It was first used as a rodenticide for the control of adult Norway rats. It was widely used in the 1940s but has subsequently been replaced by other compounds in most countries including the U.S. It is not registered for current use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. HUMAN EXPOSURE AND TOXICITY: ANTU is well absorbed by skin contact and inhalation. Oral ingestion may result in vomiting, shortness of breath, bluish discoloration of the skin, pulmonary edema or liver injury. Repeat exposures can injure the thyroid and adrenals, producing hypothyroidism. ANIMAL STUDIES: Oral feeding of ANTU to rats at 10 mg/kg body weight increased the blood glucose levels by 100% after 22 hours. Acute exposure also caused elevated plasma activities of aspartate and alanine aminotransferases and increased the activity of the lactate dehydrogenase 5 (LD5) isoenzyme, suggesting that the liver is one of the targets in poisoning in ANTU-treated rats. Toxic symptoms observed in laboratory animals given repeated doses of alpha-naphthyl thiourea include impaired weight gain and deformities of the legs and feetinhibition of hair growth and defective hair pigmentationthyroid hyperplasia and hypercholesterolemiaand fatty degeneration of the liver and bile-duct proliferation. Other effects that have been reported are inhibition of pulmonary aniline hydroxylase activity, increased pulmonary aminopyrine demethylase activity and inhibition of Na+/K+ ATPases in erythrocyte membranes and kidney microsomes. Microsomes from rat liver and lung release atomic sulfur from alpha-naphthyl thiourea. Pulmonary toxicity may result, at least in part, from binding of atomic sulfur to tissue macromolecules in susceptable species. ANTU is mutagenic when metabolized by liver microsomal fractions from rats treated with either Aroclor 1254 or phenobarbital. It also transforms hamster embryo cells in an in vitro carcinogenesis bioassay. |

| Medical Surveillance | Employees should be screened for history of certain medical conditions such as individuals with chronic respiratory disease or liver disease, which might place the employee at an increased risk from ANTU exposure. |
| Soil Adsorption/Mobility | Using a structure estimation method based on molecular connectivity indices(1), the Koc of alpha-naphthylthiourea can be estimated to be 3600(SRC). According to a classification scheme(2), this estimated Koc value suggests that alpha-naphthylthiourea is expected to have slight mobility in soil. The pKa of alpha-naphthylthiourea is estimated as 9.47(3), indicating that this compound will exist partially in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). |

Anwendungen & Verwendung
Beschreibung
a-Naphthylthiourea (ANTU; also called DIRAX) is toxic by inhalation, ingestion, or skin contact. Due to its very narrow spectrum of activity, production was discontinued a long time ago. Exposure to ANTU causes pulmonary edema; therefore, it is often used as an experimental pneumotoxin. ANTU is a graycolored, prism-shaped, odorless powder with a bitter taste. It has a molecular weight of 202.28 and melting point of 200 ℃ and does not ignite readily. However, on interaction with potential oxidizing agents, it may cause fire and explosions, which can lead to hazardous decomposition products such as sulfur dioxide, nitrogen dioxide, and carbon monoxide. The structure of ANTU contains the naphthalene chromophore, which absorbs UV light at ～311 nm. This suggests that ANTU can undergo photolysis.
