Metabolism of the antimalarial endoperoxide Ro 42-1611 (arteflene) in the rat: evidence for endoperoxide bioactivation. (1/332)

Ro 42-1611 (arteflene) is a synthetic endoperoxide antimalarial. The antimalarial activity of endoperoxides is attributed to iron(II)-mediated generation of carbon-centered radicals. An alpha, beta-unsaturated ketone (enone; 4-[2',4' bis(trifluoromethyl)phenyl]-3-buten-2-one), obtained from arteflene by reaction with iron(II), was identified previously as the stable product of a reaction that, by inference, also yields a cyclohexyl radical. The activation of arteflene in vivo has been characterized with particular reference to enone formation. [14C]Arteflene (35 micromol/kg) was given i.v. to anesthetized and cannulated male rats: 42.2 +/- 7.0% (mean +/- S.D., n = 7) of the radiolabel was recovered in bile over 5 h. In the majority of rats, the principal biliary metabolites were 8-hydroxyarteflene glucuronide (14.2 +/- 3. 9% dose, 0-3 h) and the cis and trans isomers of the enone (13.5 +/- 4.6% dose, 0-3 h). In conscious rats, 15.3 +/- 1.6% (mean +/- S.D., n = 8) of the radiolabel was recovered in urine over 24 h. The principal urinary metabolite appeared to be a glycine conjugate of a derivative of the enone. Biliary excretion of the glucuronide, but not of the enones, was inhibited by ketoconazole. 8-Hydroxyarteflene was formed extensively by rat and human liver microsomes but no enone was found. Bioactivation is a major pathway of arteflene's metabolism in the rat. Although the mechanism of in vivo bioactivation is unclear, the reaction is not catalyzed by microsomal cytochrome P-450 enzymes.  (+info)

Characterization of inhaled alpha-methylstyrene vapor toxicity for B6C3F1 mice and F344 rats. (2/332)

alpha-Methylstyrene (AMS) is a chemical intermediate used in the synthesis of specialty polymers and copolymers. Inhalation studies of AMS were conducted because of the lack of toxicity data and the structural similarity of AMS to styrene, a toxic and potentially carcinogenic chemical. Male and female B6C3F1 mice were exposed to 0, 600, 800, or 1000 ppm AMS 6 h/day, 5 days/week, for 12 days. After 1 exposure, 21% (5/24) of female mice were found dead in the 1000-ppm group, 56% (10/18) in the 800-ppm group, and 6% (1/18) in the 600-ppm concentration group. After 12 exposures, relative liver weights were significantly increased and relative spleen weights were significantly decreased in both male and female mice at all concentrations. No microscopic treatment-related lesions were observed. A decrease in hepatic glutathione (GSH) was associated with AMS exposure for 1 and 5 days. Male and female F344 rats were exposed to 0, 600 or 1000 ppm AMS for 12 days. No mortality or sedation occurred in AMS-exposed rats. Relative liver weights were significantly increased in both males and females after 12 exposures to 600 or 1000 ppm. An increased hyaline droplet accumulation was detected in male rats in both concentration groups; no significant microscopic lesions were observed in other tissues examined. Exposure of male and female F344 rats and male NBR rats to 0, 125, 250 or 500 ppm AMS, 6 h/day for 9 days resulted in increased accumulation of hyaline droplets in the renal tubules of male F344 rats in the 250 and 500 ppm concentration groups. Although AMS and styrene are structurally very similar, AMS was considerably less toxic for mice and more toxic for male rats than styrene.  (+info)

Influence of anions and cations on the dipole potential of phosphatidylcholine vesicles: a basis for the Hofmeister effect. (3/332)

Anions and cations have long been recognized to be capable of modifying the functioning of various membrane-related physiological processes. Here, a fluorescent ratio method using the styrylpyridinium dyes, RH421 and di-8-ANEPPS, was applied to determine the effect of a range of anions and cations on the intramembrane dipole potential of dimyristoylphosphatidylcholine vesicles. It was found that certain anions cause a decrease in the dipole potential. This could be explained by binding within the membrane, in support of a hypothesis originally put forward by A. L. Hodgkin and P. Horowicz [1960, J. Physiol. (Lond.) 153:404-412.] The effectiveness of the anions in reducing the dipole potential was found to be ClO4- > SCN- > I- > NO3- > Br- > Cl- > F- > SO42-. This order could be modeled by a partitioning of ions between the membrane and the aqueous phase, which is controlled predominantly by the Gibbs free energy of hydration. Cations were also found to be capable of reducing the dipole potential, although much less efficiently than can anions. The effects of the cations was found to be trivalent > divalent > monovalent. The cation effects were attributed to binding to a specific polar site on the surface of the membrane. The results presented provide a molecular basis for the interpretation of the Hofmeister effect of lyotropic anions on ion transport proteins.  (+info)

Quantitative analysis of styrene monomer in polystyrene and foods including some preliminary studies of the uptake and pharmacodynamics of the monomer in rats. (4/332)

A variety of food containers, drinking cups and cutlery, fabricated from polystyrene (PS) or polystyrene-related plastic, were analyzed for their styrene monomer content. Samples of yogurt, packaged in PS cups, were similarly analyzed and the leaching of styrene monomer from PS containers by some food simulants was also determined. Blood level studies with rats, dosed with styrene monomer by various routes, illustrated uptake phenomena that were dependent on the dose and route of administration and were also affected by the vehicle used to convey the styrene monomer.  (+info)

Hepatic and extrahepatic metabolism of 14C-styrene oxide. (5/332)

With 8-(14)C-styrene oxide as substrate, specific glutathione S-transferase and epoxide hydrase activities were determined in subcellular fractions of liver, lungs, kidney, and intestinal mucosa from rabbit, rat, and guinea pig. Liver had the highest enzyme activities in each species. Rat and guinea pig had higher glutathione S-transferase activity in both liver and kidney than rabbit. Rat testis also had appreciable glutathione S-transferase activity. The perinatal development of epoxide hydrase and glutathione S-transferase was followed in liver and several extrahepatic tissues of fetal and neonatal guinea pigs and rabbits. The rates at which enzyme activities reached adult levels in the extrahepatic tissues differed from the liver in both species. Epoxide hydrase and glutathione S-transferases developed at different rates in each organ, demonstrating that the relative importance of these two detoxifying pathways for styrene oxide may shift before and after birth. The effects of pretreating male and female rats with phenobarbital (PB), 1,2,3,4-dibenzanthracene (DBA), pregnenolone-16alpha-carbonitrile (PCN), or 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on hepatic and extrahepatic epoxide hydrase and glutathione S-transferase activities toward styrene oxide were determined. PB increased both enzyme activities in liver of both sexes. PCN induced only glutathione S-transferase activity in female liver. Extrahepatic epoxide hydrase and glutathione S-transferase activities were unaffected except that TCDD doubled female renal epoxide hydrase activity and PB increased intestinal epoxide hydrase activity in both sexes. Styrene oxide biotransformation was studied in isolated, perfused rat liver and rabbit lung preparations. Conjugation with glutathione was a major metabolic pathway although significant amounts of diol were also formed in each instance. In rat liver, 27-40% of the administered styrene oxide was excreted via the bile mainly as S-(1-phenyl-2-hydroxyethyl)glutathione.  (+info)

Clinical studies of styrene workers: initial findings. (6/332)

Styrene monomer is a high volume chemical used chiefly in production of polystyrene. A clinical survey of 493 production workers was undertaken at the oldest and largest monomer production, polymerization, and extrusion facility in the U.S. Relative exposure durations and levels were obtained from occupational histories. Significant differences between the high and low exposure groups were found with regard to history of acute prenarcotic symptoms, acute lower respiratory symptoms, prevalence of FEV 1/FV less than 75 per cent, and elevated GCTP. Other liver function tests, chest x-ray, FVC less than 80 per cent, and hematological parameters showed no distinct pattern. A concomitant mortality study has been mounted and is in progress.  (+info)

Hofmeister effects of anions on the kinetics of partial reactions of the Na+,K+-ATPase. (7/332)

The effects of lyotropic anions, particularly perchlorate, on the kinetics of partial reactions of the Na+,K+-ATPase from pig kidney were investigated by two different kinetic techniques: stopped flow in combination with the fluorescent label RH421 and a stationary electrical relaxation technique. It was found that 130 mM NaClO4 caused an increase in the Kd values of both the high- and low-affinity ATP-binding sites, from values of 7.0 (+/- 0.6) microM and 143 (+/- 17) microM in 130 mM NaCl solution to values of 42 (+/- 3) microM and 660 (+/- 100) microM in 130 mM NaClO4 (pH 7.4, 24 degrees C). The half-saturating concentration of the Na+-binding sites on the E1 conformation was found to decrease from 8-10 mM in NaCl to 2.5-3.5 mM in NaClO4 solution. The rate of equilibration of the reaction, E1P(Na+)3 left arrow over right arrow E2P + 3Na+, decreased from 393 (+/- 51) s-1 in NaCl solution to 114 (+/- 15) s-1 in NaClO4. This decrease is attributed predominantly to an inhibition of the E1P(Na+)3 --> E2P(Na+)3 transition. The effects can be explained in terms of electrostatic interactions due to perchlorate binding within the membrane and/or protein matrix of the Na+,K+-ATPase membrane fragments and alteration of the local electric field strength experienced by the protein. The kinetic results obtained support the conclusion that the conformational transition E1P(Na+)3 --> E2P(Na+)3 is a major charge translocating step of the pump cycle.  (+info)

Effect of gramicidin A on the dipole potential of phospholipid membranes. (8/332)

The effect of channel-forming peptide gramicidin A on the dipole potential of phospholipid monolayers and bilayers has been studied. Surface pressure and surface potential isotherms of monolayers have been measured with a Langmuir trough equipped with a Wilhelmy balance and a surface potential meter (Kelvin probe). Gramicidin has been shown to shift pressure-area isotherms of phospholipids and to reduce their monolayer surface potentials. Both effects increase with the increase in gramicidin concentration and depend on the kind of phosphatidylcholine used. Application of the dual-wavelength ratiometric fluorescence method using the potential-sensitive dye RH421 has revealed that the addition of gramicidin A to dipalmitoylphosphatidylcholine liposomes leads to a decrease in the fluorescence ratio of RH421. This is similar to the effect of phloretin, which is known to decrease the dipole potential. The comparison of the concentration dependences of the fluorescence ratio for gramicidin and phloretin shows that gramicidin is as potent as phloretin in modifying the membrane dipole potential.  (+info)

Needed areas of future research on styrene include studies on the molecular dosimetry of styrene in terms of both hemoglobin and DNA adducts. The results of such research should improve our ability to assess the relationship between exposure to styrene and surrogate
The experimental data on acute toxicity of styrene include studies by inhalation and oral exposure performed in rodents. The data on oral exposure to styrene are, generally, well above the threshold for classification of styrene for acute toxicity (i.e. , 2000 mg/kg bw). However, the data on acute toxicity in rats via inhalation exposure route (10 mg/L ,LC50 ≤ 20 mg/L) suggest moderate acute toxicity of styrene. Styrene has harmonized at EU level classifications and it is classified as Xn; R20 - Harmful by inhalation, in accordance with Directive 67/548/EEC, and Acute Toxicity, Hazard Category 4, H332: Harmful if inhalled, in accordance with the GHS criteria of Regulation (EC) No 1272/2008. In general, high concentrations of styrene were reported to result in dizziness, drowsiness, headache, nausea, vomiting, weakness, and unconsciousness. Given, that styrene is used in industry for a long time, the lack of reports on serious adverse acute toxicity effects (e.g., death) of styrene support the ...

In 1996, the allied styrene industry associations signed a voluntary agreement with OSHA to encourage compliance with an industry exposure guideline of 50 ppm for an 8-hour average and 100 ppm for 15-minute exposure. The agreement with OSHA requires composites manufacturers to use engineering controls, including pollution prevention techniques such as low-styrene resin as well as ventilation, and administrative controls such as job rotation, to reduce exposures to 100 ppm. Then, if necessary, personal protective equipment (respirators) can be used to achieve the 50 ppm limit. Using low-emitting processes, ventilation and respirators, the large majority of composite manufacturers are complying with these recommended exposure limits.. Questions remained, however, regarding the appropriate level to ensure worker health and safety. While the extensive studies with more than 55,000 styrene workers did not show any styrene-related excess of cancer or other chronic disease, there have long been a ...

Styrene 7,8-oxide, which reacts preferentially at the N-7 position of guanine, yielded two pairs of diastereomers 7-(1-hydroxy-2-phenylethyl)-dGMP (the alpha-isomer) and 7-(2-hydroxy-2-phenylethyl)-dGMP (the beta-isomer) on reaction with deoxyguanosine-3-monophosphate (3-dGMP). The alpha- and beta-isomers were formed in the ratio 32:68. T4 polynucleotide kinase preferentially mediated labelling of diastereomers corresponding to the beta-isomer. The beta-diastereomers showed a labelling efficiency of 52%, whereas the alpha-isomers showed a labelling efficiency of 4%. Molecular modelling experiments showed intrinsic differences between the two isomers. The torsion angles of C8-N7-2-Ar and C8-N7-2-1 for the alpha-isomers were 149.9 degrees and -26.4 degrees, whereas the torsion angles of C-8-N7-1-2 and N7-1-2-Ar for the beta-isomers were 105.3 degrees and 179.4 degrees. The consequent interatomic distance between one of the hydrogens on the alpha-carbon and the 3-phosphate group on the ...

VOCs [Avoidable]. Volatile Organic compounds create little discomfort short term, before creating significant damage to our health long term. It is the long term effects of VOCs which have created new changes in the medical view leading to better investigation of the environment which ails the Asthma Prone.. Long term exposure to VOCs which have been past tolerated by those exposed have caused cataclysmic disorders such as lung, liver and other cancers. Those exposed to VOCs have tolerated the short term side effects such as headaches and dizziness but with dire long term consequences.. Noticeably styrenes and uPVC systems are prolific in Poland and have become the norm in Polish construction. Styrenes emit VOCs at acceptable levels only providing they are well ventilated when they can seemingly have only minor effect on public health. Unfortunately now styrenes are used to tighten buildings, reducing ventilation they can have a prolific impact on the enclosed environment. EVE® team ...

A styrene monooxygenase (SMO; EC 1.14.14.11) is an enzyme that catalyzes the chemical reaction styrene + FADH2 + O2 ↔ (S)-2-phenyloxirane + FAD + H2O as the first step of the aerobic styrene degradation pathway. The product 2-phenyloxirane is also known as styrene oxide and can be converted by a styrene oxide isomerase (SOI) to obtain phenylacetaldehyde, which can be transformed into the key-intermediate phenylacetic acid by a phenylacetaldehyde dehydrogenase (PAD). The enzyme belongs to the group of oxidoreductases according EC classification and is dependent on FAD as cofactor, thus it was classified as an external flavoprotein monooxygenase (designated as type E). It forms a two-component system with a reductase (StyB, StyA2B). The reductase utilizes solely NADH to reduce the FAD, which is then transferred to the styrene monooxygenase (StyA, StyA1). Two types of that enzyme are described so far: StyA/StyB (designated E1), first described from Pseudomonas species, and StyA1/StyA2B ...

Similar to acrylonitrile[17], benzene[18], bisphenol A and phthalates, plastic drink containers[19]] and plastic liners in cans and other polystyrene foam packages[20] are a source of styrene exposure from food/drinks. Except for polystyrene egg cartons, which leak no styrene into eggs.[21] Bottled drinking water may contain styrene (up to 29.5 mcg/L; increased to 69.53 mcg/L after 1 yr storage) leached from the polystyrene (PS) bottle.[22] Migration of styrene from disposable cups (styrofoam and PS, not paper cups) into drinks highly depends on fat content and temperature of drinks.[23] Up to 150 mg styrene /kg was transferred from polystyrene disposables into sunflower oil and up to 90 mg/kg into individual serving milk products.[24] Butter[25], yoghurt[26][27] may also contain styrene, as the migration of styrene from packaging material very much depends on fat-contents of the liquid/food (and temperature).[28] In the US, the exposure to styrene from polystyrene food-contact articles is ...
To investigate the carcinogenicity of styrene by reanalysing data from a previous international cohort study of workers in the reinforced plastics industry. Methods Mortality from cancers of prior interest was analysed with more detailed consideration of exposure-response relations and an updated classification of leukaemias and lymphomas in data from a previous international cohort study of 37 021 reinforced plastics workers exposed to airborne styrene. Results Increased mortality from non-Hodgkins lymphoma (NHL) was associated with the mean level of exposure to styrene in air (relative risk (RR) 2.31, 95% CI 1.29 to 4.12 per 100 ppm), but not with cumulative styrene exposure. Similar associations with mean exposure were observed for the oesophagus (RR 2.44, 95% CI 1.11 to 5.36 per 100 ppm) and pancreas (RR 1.89, 95% CI 1.17 to 3.09). Oesophageal cancer mortality was also associated with cumulative styrene exposure lagged 20 years (RR 1.16, 95% CI 1.03 to 1.31). No other cancer, including lung ...

Over the past several years, mandelic acid has been steadily gaining in popularity. Why is mandelic acid such an effective treatment for acne, rosacea, hyperpigmentation, and fine lines & wrinkles? Why should you consider incorporating mandelic acid into your skincare regimen? Lets take a brief look at the history & science behind this all-star A.H.A.. Mandelic acid was originally discovered by J. W. Walker and V. K. Krieble a little over a century ago in 1909. Extracted from bitter almonds (the name comes from the German word mandel, which means almond), mandelic acid is actually the strongest A.H.A. that exists in nature. For decades, it has been used in the medical community as an antimicrobial agent, typically after laser skin treatments. Mandelic acid is now commonly used as a stand-alone chemical peel treatment (or in combination with other acids), and has also been incorporated into several specialty skincare formulations. However, only less concentrated formulations can be used ...
Chemicals are used in manufacturing to make everything from food containers to your favorite pair of shoes. One such chemical is styrene, a colorless, strong-smelling liquid used to make plastics and rubber for these products and others, including insulation, fiberglass, pipes, vehicle parts, and carpet backing. During the manufacturing process, chemical vapors contaminate the air. When workers breathe in this contaminated air, styrene exposure can occur.

With a good start the Boys at the Clearwater Car Shops thought it was time to report their progress to The Boss on their mixed styrene/resin project to build a model of a double-sheathed Piedmont & Northern boxcar, originally built I think for the Pere Marquette as a 1½ door or double door auto car. The vertical rib ends came from Dr. Dave Campbell. To make assembly easy I laminated some 0.005 strips of styrene to the back edges of each end.. I made the sides from Evergreens passenger car siding and used .125 x .125 styrene on each end where it will meet the styrene laminated on the ends. In between are more lengths of .125 x .125 styrene the length of the sides to stiffen each side. I used Testors liquid for this work.. Fortunately Tichy has a set of Youngstown doors (#3018) that with easy modification are accurate for this model. I used my UMM Razor Blade Saw to cut off the very top of the door-the top two corrugations-then cut the top rib from the top of the top panel. I did this for both ...
Styrene is used in polymer chemistry as a monomer. This means many styrene molecules can bond together to make a larger molecule called polystyrene. Polystyrene is a kind of polymer often used as a plastic. This kind of chemical reaction is called polymerization. Styrene can also bond with other kinds of monomers to make other kinds of polymers called copolymers. For one example, styrene has been mixed with another monomer called 1,3-butadiene to make a copolymer which is a kind of synthetic rubber. For another example, styrene is mixed with acrylonitrile and 1,3-butadiene to make a copolymer plastic called ABS (Acrylonitrile-Butadiene-Styrene). ...

From experience when you bought those at K-mart, not eBay. Styrene was used because it was cheaper than vinyl. Not just because of the molds (which really didnt last that much longer). By the 70s, oil prices had reached a point where the cost of vinyl was such that a LOT of singles were styrene. The vinyl was saved for LPs. And singles were considered throw-away items. So then, it didnt matter. As for the machines, if you ever seen pictures of plastic model making (think How Its Made on TV) that is the idea. The tricky part was the tool (the molds) for most styrene products are machined. For singles, they had to do all the steps they would for making vinyl stampers, but instead use a soft metal and die cast the two halves of the mold from the nickel mother disc. If that material (usually aluminum) got too hot, then there would be deformities caused by distorting the mother in the die casting process. Styrene CAN be okay if the proper care was taken. But alas, often it wasnt ...

The initial inspiration for the family was a charmingly awkward sans serif called Breede Schreeflooze shown in an early 20th century type specimen published by the Enschedé Typefoundry in the Netherlands. However, Styrene has an ahistorical attitude. Its name was inspired by the purposefully synthetic feeling to its curves and geometry. Styrene is characterized by its proportions: typically narrow characters like f j r and t are hyperextended and flattened, adding openness in unexpected places. Styrenes two widths offer different textures in text: version A is dogmatically geometric, with a stronger overall personality, while version B is narrower for more reasonable copyfit, though not truly condensed.. ...

Styrene monooxygenase (SMO) catalyzes the first step of aromatic alkene degradation yielding the corresponding epoxides. Because of its broad spectrum of substrates, the enzyme harbors a great potential for an application in medicine and chemical industries. In this study, we achieved higher enzymatic activity and better stability towards styrene by enlarging the ligand entrance tunnel and improving the hydrophobicity through error-prone PCR and site-saturation mutagenesis. It was found that Asp305 (D305) hindered the entrance of the FAD cofactor according to the model analysis. Therefore, substitution with amino acids possessing shorter side chains, like glycine, opened the entrance tunnel and resulted in up to 2.7 times higher activity compared to the wild-type enzyme. The half-lives of thermal inactivation for the variant D305G at 60 °C was 28.9 h compared to only 3.2 h of the wild type SMO. Moreover, overexpression of SMO in Pseudomonas putida KT2440 with NADH regeneration was carried out in order

Much has been talking about the advantages of polymeric nanocomposites, but little is known about the influence of nanoparticles on the stability of these materials. In this sense, we studied the influence of both oxides of zirconium and titanium, known to have photocatalytic properties, as well as the influence of synthetic clay Laponite on the photodegradation of styrene-butadiene rubber (SBR). SBR nanocomposites were prepared by the colloidal route by mixing commercial polymer lattices and nanometric anatase TiO2, monoclinic ZrO2 or exfoliated Laponite clays colloidal suspensions. To better understand the degradation mechanisms that occur in these nanocomposites, the efficiency of different photocatalysts under ultraviolet radiation was monitored by FT-IR and UV-vis spectroscopies and by differential scanning calorimetric. It was observed that TiO2 and ZrO2 nanoparticles undoubtedly acted as catalysts during the photodegradation process with different efficiencies and rates. However, when ...

The present invention relates to a method for production of styrene, which is in contact with the catalyst feedstock containing arrowy alcohol, more specifically, the feedstock containing 1-phenylethanol (also known under the names α-phenylethanol, or methylphenylcarbinol) and/or substituted 1-phenylethanol.. Well-known way in which arrowy alcohol is subjected to chemical conversion using the catalyst, is the way in which ethylbenzene receive propylene oxide and styrene. In General, this method involves the following stages (i) interaction of ethylbenzene with oxygen or air with getting ethylbenzothiazoline, (ii) interaction thus obtained ethylbenzothiazoline with propene in the presence of an epoxidation catalyst to obtain propylene oxide and 1-phenylethanol and (iii) the conversion of 1-phenylethanol in styrene by dehydration using a suitable dehydration catalyst.. Another well-known method comprises the production of propylene oxide by using cumene. In this way the hydroperoxide reacts with ...
