Solid-phase microextraction and GC-ECD of benzophenones for detection of benzodiazepines in urine. (1/275)

Benzodiazepines are common drugs that cause intoxication. Benzodiazepines and their metabolites can be converted by hydrolysis in acid to the corresponding benzophenones, which are easier to be separated from matrices because of their hydrophobic properties. In this study, a new separation technique called solid-phase microextraction (SPME), which can integrate extraction, concentration, sampling and sample introduction into one single procedure, has been employed to extract the products of benzodiazepines from urine after acid hydrolysis. The extracts were determined by gas chromatography with electron-capture detection (GC-ECD). The hydrolysis conditions were optimized by a statistic orthogonal design. Factors influencing direct-immersion (DI)-SPME process were also checked and chosen experimentally. The method was evaluated with spiked human urine samples. The recoveries of nine benzodiazepines ranged from 1 to 25%, with the highest for oxazolam and the lowest for bromazepam. The calibration curves were linear from 10 to 500 ng/mL for oxazolam, haloxazolam, flunitrazepam, nimetazepam, and clonazepam and from 20 to 1000 ng/mL for the others except bromazepam. The detection limits were 2-20 ng/mL for most drugs tested. The intraday and interday coefficients of variation of the developed method were within 10 and 17%, respectively. In addition, the utility of the method was confirmed by determining two ingested benzodiazepines (flunitrazepam and oxazolam) in a volunteer's urine; urine flunitrazepam was still detectable 32 h after a therapeutic dose (1.2 mg) of the drug. Finally, the DI-SPME was compared with the conventional liquid-liquid extraction with regard to detection limits and extraction efficiency of the analytes. By DI-SPME, more amounts of analytes could be introduced into GC column than by conventional liquid-liquid extraction, and thus lower detection limits of the analytes were reached, although benzophenone recoveries by DI-SPME were rather low.  (+info)

Mechanism of regulation of hsp70 chaperones by DnaJ cochaperones. (2/275)

Hsp70 chaperones assist a large variety of protein folding processes within the entire lifespan of proteins. Central to these activities is the regulation of Hsp70 by DnaJ cochaperones. DnaJ stimulates Hsp70 to hydrolyze ATP, a key step that closes its substrate-binding cavity and thus allows stable binding of substrate. We show that DnaJ stimulates ATP hydrolysis by Escherichia coli Hsp70, DnaK, very efficiently to >1000-fold, but only if present at high (micromolar) concentration. In contrast, the chaperone activity of DnaK in luciferase refolding was maximal at several hundredfold lower concentration of DnaJ. However, DnaJ was capable of maximally stimulating the DnaK ATPase even at this low concentration, provided that protein substrate was present, indicating synergistic action of DnaJ and substrate. Peptide substrates were poorly effective in this synergistic action. DnaJ action required binding of protein substrates to the central hydrophobic pocket of the substrate-binding cavity of DnaK, as evidenced by the reduced ability of DnaJ to stimulate ATP hydrolysis by a DnaK mutant with defects in substrate binding. At high concentrations, DnaJ itself served as substrate for DnaK in a process considered to be unphysiological. Mutant analysis furthermore revealed that DnaJ-mediated stimulation of ATP hydrolysis requires communication between the ATPase and substrate-binding domains of DnaK. This mechanism thus allows DnaJ to tightly couple ATP hydrolysis by DnaK with substrate binding and to avoid jamming of the DnaK chaperone with peptides. It probably is conserved among Hsp70 family members and is proposed to account for their functional diversity.  (+info)

Comparison of the potassium channel openers, WAY-133537, ZD6169, and celikalim on isolated bladder tissue and In vivo bladder instability in rat. (3/275)

The effects of the ATP-dependent potassium channel agonists ZD6169, celikalim, and WAY-133537 on bladder contractile function were examined in vitro on isolated bladder strips and in vivo on spontaneous bladder contractions. All three compounds produced a concentration-dependent relaxation of isolated rat detrusor strips (IC50 values = 0.93, 0.03, and 0.09 microM, respectively for ZD6169, celikalim, and WAY-133537. Contractile inhibition by all three compounds was fully reversed by 6 microM glyburide. These compounds also effectively inhibited spontaneous bladder contractions in the rat hypertrophied bladder model of detrusor instability. We also examined the electrophysiological properties of WAY-133537 on isolated rat bladder detrusor myocytes. Myocytes had an average resting membrane potential of -40 mV. Under patch current-clamp conditions, WAY-133537 (0.3 and 1.0 microM, n = 4-5) produced a significant hyperpolarization of 21 and 26 mV, respectively. Hyperpolarization was reversed by the addition of 5 microM glyburide. In patch voltage-clamp studies, WAY-133537 (0.3 microM, n = 3) significantly increased outward current in response to both voltage step and ramp protocols consistent with activation of the ATP-dependent potassium channel. In the detrusor instability model, WAY-133537 and celikalim had similar oral potencies (ED50 = 0.13 and 0.3 mg/kg, respectively), whereas ZD6169 was less potent (ED50 = 2.4 mg/kg). The antihypertensive agent celikalim exerted effects on the bladder at doses that significantly reduced systemic blood pressure. In contrast, both WAY-133537 and ZD6169 inhibited bladder hyperactivity at doses that produced minimal changes in both mean arterial blood pressure and heart rate. These data suggest that both WAY-133537 and ZD6169 may be useful in the treatment of bladder instability at doses associated with minimal hemodynamic side effects.  (+info)

Guanosine triphosphatase stimulation of oncogenic Ras mutants. (4/275)

Interest in the guanosine triphosphatase (GTPase) reaction of Ras as a molecular drug target stems from the observation that, in a large number of human tumors, Ras is characteristically mutated at codons 12 or 61, more rarely 13. Impaired GTPase activity, even in the presence of GTPase activating proteins, has been found to be the biochemical reason behind the oncogenicity of most Gly12/Gln61 mutations, thus preventing Ras from being switched off. Therefore, these oncogenic Ras mutants remain constitutively activated and contribute to the neoplastic phenotype of tumor cells. Here, we show that the guanosine 5'-triphosphate (GTP) analogue diaminobenzophenone-phosphoroamidate-GTP (DABP-GTP) is hydrolyzed by wild-type Ras but more efficiently by frequently occurring oncogenic Ras mutants, to yield guanosine 5'-diphosphate-bound inactive Ras and DABP-Pi. The reaction is independent of the presence of Gln61 and is most dramatically enhanced with Gly12 mutants. Thus, the defective GTPase reaction of the oncogenic Ras mutants can be rescued by using DABP-GTP instead of GTP, arguing that the GTPase switch of Ras is not irreversibly damaged. An exocyclic aromatic amino group of DABP-GTP is critical for the reaction and bypasses the putative rate-limiting step of the intrinsic Ras GTPase reaction. The crystal structures of Ras-bound DABP-beta,gamma-imido-GTP show a disordered switch I and identify the Gly12/Gly13 region as the hydrophobic patch to accommodate the DABP-moiety. The biochemical and structural studies help to define the requirements for the design of anti-Ras drugs aimed at the blocked GTPase reaction.  (+info)

The binding site for an inhibitor of squalene:hopene cyclase determined using photoaffinity labeling and molecular modeling. (5/275)

BACKGROUND: The squalene:hopene cyclases (SHCs) are bacterial enzymes that convert squalene into hopanoids, a function analogous to the action of oxidosqualene cyclases (OSCs) in eukaryotic steroid and triterpenoid biosynthesis. We have identified the binding site for a selective, potent, photoactivatable inhibitor of an SHC. RESULTS: SHC from Alicyclobacillus acidocaldarius was specifically labeled by [3H]Ro48-8071, a benzophenone-containing hypocholesteremic drug. Edman degradation of a peptide fragment of covalently modified SHC confirmed that Ala44 was specifically modified. Molecular modeling, using X-ray-derived protein coordinates and a single point constraint for the inhibitor, suggested several geometries by which Ro48-8071 could occupy the active site. CONCLUSIONS: A covalent complex of a potent inhibitor with a squalene cyclase has been characterized. The amino acid modification and molecular modeling suggest that Ro48-8071 binds at the junction between the central cavity and substrate entry channel, therefore inhibiting access of the substrate to the active site.  (+info)

A novel N-aryl tyrosine activator of peroxisome proliferator-activated receptor-gamma reverses the diabetic phenotype of the Zucker diabetic fatty rat. (6/275)

The discovery that peroxisome proliferator-activated receptor (PPAR)-gamma was the molecular target of the thiazolidinedione class of antidiabetic agents suggested a key role for PPAR-gamma in the regulation of carbohydrate and lipid metabolism. Through the use of high-throughput biochemical assays, GW1929, a novel N-aryl tyrosine activator of human PPAR-gamma, was identified. Chronic oral administration of GW1929 or troglitazone to Zucker diabetic fatty (ZDF) rats resulted in dose-dependent decreases in daily glucose, free fatty acid, and triglyceride exposure compared with pretreatment values, as well as significant decreases in glycosylated hemoglobin. Whole body insulin sensitivity, as determined by the euglycemic-hyperinsulinemic clamp technique, was significantly increased in treated animals. Comparison of the magnitude of glucose lowering as a function of serum drug concentrations showed that GW1929 was 2 orders of magnitude more potent than troglitazone in vivo. These data were consistent with the relative in vitro potencies of GW1929 and troglitazone. Isolated perfused pancreas studies performed at the end of the study confirmed that pancreata from vehicle-treated rats showed no increase in insulin secretion in response to a step change in glucose from 3 to 10 mmol/l. In contrast, pancreata from animals treated with GW1929 showed a first- and second-phase insulin secretion pattern. Consistent with the functional data from the perfusion experiments, animals treated with the PPAR-gamma agonist had more normal islet architecture with preserved insulin staining compared with vehicle-treated ZDF rats. This is the first demonstration of in vivo efficacy of a novel nonthiazolidinedione identified as a high-affinity ligand for human PPAR-gamma. The increased potency of GW1929 compared with troglitazone both in vitro and in vivo may translate into improved clinical efficacy when used as monotherapy in type 2 diabetic patients. In addition, the significant improvement in daily meal tolerance may impact cardiovascular risk factor management in these patients.  (+info)

Effects of ZD6169, a K(ATP) channel opener, on the micturition reflex in the rat. (7/275)

The effects of ZD6169, a new ATP-sensitive potassium channel opener, on reflex urinary bladder activity were evaluated in urethane-anesthetized female Wistar rats. Continuous transvesical slow infusion cystometrograms (0.04 ml/min) were performed in untreated, capsaicin-pretreated (125 mg/kg s.c., 4 days before experiments) and capsaicin vehicle-pretreated rats. Intravesical infusion of ZD6169 in concentrations of 6, 15, 30, and 300 nM for 2 h at each concentration increased the intercontraction interval and pressure threshold for voiding in a concentration-dependent manner in untreated and vehicle-pretreated rats but not in capsaicin-pretreated animals. The effects appeared within 30 min after administration. ZD6169 did not alter baseline bladder pressure, duration of contractions, or the peak pressure during voiding. Glibenclamide (20 mg/kg i.v.) reversed the effects of ZD6169 (30 nM). During transvesical cystometrograms performed at a fast rate (0.21 ml/min), ZD6169 in concentrations between 6 and 300 nM did not alter the intercontraction interval or pressure threshold for voiding. ZD6169 produced smaller and more variable effects during slow transurethral cystometrograms. Capsaicin, a C-fiber afferent neurotoxin, administered s.c. 4 days before the experiment, produced similar changes and also eliminated the effect of ZD6169. These data suggest that ZD6169 raises the threshold for activation of C-fiber mechanoreceptors in the bladder wall and thereby increases the bladder volume for inducing reflex voiding.  (+info)

Differential and selective inhibition of protein kinase A and protein kinase C in intact cells by balanol congeners. (8/275)

The fungal metabolite balanol is a potent inhibitor of protein kinase A (PKA) and protein kinase C (PKC) in vitro that acts by competing with ATP for binding (K(i) approximately 4 nM); congeners of balanol show specificity for PKA over PKC. We have characterized the effects of balanol and 10"-deoxybalanol in intact cells to determine whether these compounds cross the cell membrane and whether the potency and specificity noted in vitro are preserved in vivo. In neonatal rat myocytes and cultured A431 cells transiently transfected with a cyclic AMP response element-luciferase reporter construct, balanol inhibits the induction of luciferase activity by isoproterenol, indicating inhibition of PKA. Western analysis shows that both balanol and 10"-deoxybalanol reduce phosphorylation of cAMP response element-binding protein in isoproterenol-stimulated A431 cells; inhibition is concentration dependent with an IC(50) value of approximately 3 microM. Balanol, but not 10"-deoxybalanol, inhibits phosphorylation of the myristoylated alanine-rich C kinase substrate protein, a PKC substrate, in phorbol ester-stimulated A431 cells (IC(50) approximately 7 microM). Our data demonstrate that balanol is a potent inhibitor of PKA and PKC in several whole-cell systems and causes no obvious toxicity. In addition, balanol congeners inhibit PKA and PKC with the specificity and potency predicted by in vitro experiments.  (+info)

Improvement of Prepulse Inhibition and Executive Function by the COMT Inhibitor Tolcapone Depends on COMT Val158Met...Improvement of Prepulse Inhibition and Executive Function by the COMT Inhibitor Tolcapone Depends on COMT Val158Met...
Recent evidence suggests that prepulse inhibition (PPI) levels relate to executive function possibly by a prefrontal cortex (PFC) dopamine (DA) link. We explored the effects of enhanced PFC DA signaling by the nonstimulant catechol-O-methyltransferase (COMT) inhibitor tolcapone, on PPI and working memory of subjects homozygous for the Val (low PFC DA) and the Met (high PFC DA) alleles of the COMT Val158Met polymorphism. Twelve Val/Val and eleven Met/Met healthy male subjects entered the study. Tolcapone 200 mg was administered in two weekly sessions, according to a balanced, crossover, double-blind, placebo-controlled design. PPI was assessed with 5 dB and 15 dB above background prepulses, at 30-, 60-, and 120 ms prepulse-pulse intervals. Subjects also underwent the n-back and the letter-number sequencing (LNS) tasks. PPI was lower in the Val/Val compared to the Met/Met group in the placebo condition. Tolcapone increased PPI significantly in the Val/Val group and tended to have the opposite effect in

The present study confirms and extends previous findings28 29 that tolcapone enhances the efficacy of levodopa. Whereas initial studies were focused on single dose6 or short term (one to six weeks) multiple dose22 26 coadministration of tolcapone with levodopa/decarboxylase inhibitor, the present study showed that multiple dose (tid) treatment with tolcapone results in reduced severity of wearing off type motor fluctuations in levodopa treated patients for three months and that this response is maintained over time.. Treatment with tolcapone significantly decreased mean off time (by ,20%) and increased mean on time (by ,25%), compared with placebo. Analysis of primary end point on/off data disclosed that both tolcapone dosages were equally effective in increasing on time, but the 100 mg tid dosage was more effective in decreasing off time. However, the mean reduction in levodopa dosage by month 3 was greater with 200 mg tolcapone tid than with 100 mg tid This reduction was maintained ...

The hydrogen abstraction reaction of benzophenones in micellar interiors was studied by the effect of a short, resonant microwave pulse on the recombination kinetics under magnetic fields of approximately 0.3 T. This technique allows all the significant rate constants in the reaction to be determined, in particular the singlet state recombination rate constant, which is very difficult to accurately determine by other techniques. This is determined to be 1.90 × 107 s-1 for benzophenone (BP) and 1.83 × 107 s-1 for decafluorobenzophenone in sodium dodecyl sulfate (SDS) micelles, indicating that this value is not limited by the rate of spin mixing, and thus that the kinetic approach used is justified. It also indicates that recombination is limited by re-encounter frequency and is not dependent upon substitution in the ketyl radical. All kinetic parameters are extracted for each system using a combination of single pulse and pulse shift measurements. Data are also presented for the reactions of BP ...

Abstract for TER98005 on BenzophenoneAbstract for TER98005 on Benzophenone
Benzophenone occurs naturally in some fruits and is used commercially as a perfumery and flavoring ingredient. This study was performed in response to the potential for human exposure and the lack of pertinent developmental toxicity data. Dose selection was based on a screening study in which Sprague-Dawley-derived (CD) rats were treated by gavage with benzophenone (0, 25, 50, 100, 200, or 300 mg/kg body weight/day) on gestational days 6 through 19 (NTP, 1998b). Maternal toxicity was found at all doses, but evidence of developmental toxicity was limited to a 6-8% decrease for average fetal body weight per litter (not statistically significant) at the high dose. In this study, benzophenone (100, 200, or 300 mg/kg/day) or its vehicle (0.5% methylcellulose) was administered to female CD rats by gavage on gd 6 through 19. The dose volume was 5 ml/kg. Twenty-five to 26 timed-mated rats were assigned to each group. Dams were monitored at regular intervals throughout gestation for clinical signs, feed ...

The photochemistry of N-methyllutidone, which is a model compound of pyrimidine bases, is investigated. When N-methyllutidone is irradiated with ultravioletlight (λ＜300nm) in acetonitrile with benzophenone, four products are formed. Three of the photoproducts are separated by column chromatography and characterized by spectroscopic methods and comparing with authentic sample. Three photoproducts are N-(benzhydrylmethyl) lutidone, N-(4-benzoylbenzyl) lutidone, and lutidone, with quantum yiels of $5.07\times10^{-3}$, $1.43\times10^{-3}$, $1.84\times10^{-3}$ respectively. Three photoproducts are proposed to be formed through the reaction of two free radicals, which are originated from the photochemical hydrogen atom abstraction by benzophenone from N-methyllutidone. Benzophenone is not functioning as a photosensitizer for the photoreaction of N-methyllutidone. The luminescence of N-methyllutidone in ethanol at 77˚k is studied. No fluorescence is observed but strong phosphorescence is observed. ...

We report the observation and detailed analysis of optically-detected magnetic resonance (ODMR), radio frequency (RF) saturated ODMR and electron-nuclear double resonance (ENDOR) spectra of the lowest $^{3}(n\pi^{*})$ state of oxygen-17 labelled benzophenone ($^{17}O$-BP) in zero-field (zf). The experiments were performed at 1.4K on a single crystal sample of 4,4^{\prime}-dibromidiphenylether (DDE) containing 0.1 mol % of an isotopically-enriched guest ($^{17}O$-BP; 11.3%). Allowed transitions and forbidden transitions were assigned from low power ODMR spectra and RF saturated ODMR spectra respectively. These assignments were confirmed by ENDOR experiments. The hyperfine coupling constants and nuclear quadrupole coupling constants ($e^{2}$qQ and $\eta$) were obtained for the $^{17}O$ atom. The data indicate that (1) the n electron is highly localized on the oxygen atom in $^{3}(n\pi^{*})$ benzophenone, (2) the higher order hyperfine interaction is important due to large hyperfine coupling ...

Degradation Products of Benzophenone-3 in Chlorinated Seawater Swimming Pools | Laboratoire Chimie EnvironnementDegradation Products of Benzophenone-3 in Chlorinated Seawater Swimming Pools | Laboratoire Chimie Environnement
Oxybenzone (2-hydroxy-4-methoxyphenone, benzophenone-3) is one of the UV filters commonly found in sunscreens. Its presence in swimming pools and its reactivity with chlorine has already been demonstrated but never in seawater swirnrning pools. In these pools, chlorine added for disinfection results in the formation of bromine, due to the high levels of bromide in seawater, and leads to the formation of brominated disinfection byproducts, known to be more toxic than chlorinated ones. Therefore, it seems important to determine the transformation products of oxybenzone in chlorinated seawater swimming pools; especially that users of seawater swimming pools may apply sunscreens and other personal-care products containing oxybenzone before going to pools. This leads to the introduction of oxybenzone to pools, where it reacts with bromine. For this purpose, the reactivity of oxybenzone has been examined as a function of chlorine dose and temperature in artificial seawater to assess its potential to ...

Tolcapone - WikipediaTolcapone - Wikipedia
Tolcapone (brand name Tasmar) is a drug used to treat Parkinsons disease (PD). It is a selective, potent and reversible nitrocatechol-type inhibitor of the enzyme catechol-O-methyltransferase (COMT). It has demonstrated significant liver toxicity, which has led to suspension of marketing authorisations in a number of countries. In comparison with entacapone, another nitrocatechol COMT inhibitor, tolcapone has a longer half life (2.9 hours vs. 0.8 hours) and can better penetrate the blood-brain barrier, acting both in the central nervous system and in the periphery. However, entacapone is less toxic for the liver. Tolcapone is used in the treatment of Parkinsons disease as an adjunct to levodopa/carbidopa or levodopa/benserazide medications. Levodopa is a prodrug for dopamine, which reduces Parkinson symptoms; carbidopa and benserazide are aromatic L-amino acid decarboxylase (AADC) inhibitors. Without administration of tolcapone, the beneficial effects of levodopa tend to wear off more quickly, ...

Genotype-Dependent Effects of COMT Inhibition on Cognitive Function in a Highly Specific, Novel Mouse Model of Altered COMT...Genotype-Dependent Effects of COMT Inhibition on Cognitive Function in a Highly Specific, Novel Mouse Model of Altered COMT...
Catechol-O-methyltransferase (COMT) modulates dopamine levels in the prefrontal cortex. The human gene contains a polymorphism (Val158Met) that alters enzyme activity and influences PFC function. It has also been linked with cognition and anxiety, but the findings are mixed. We therefore developed a novel mouse model of altered COMT activity. The human Met allele was introduced into the native mouse COMT gene to produce COMT-Met mice, which were compared with their wild-type littermates. The model proved highly specific: COMT-Met mice had reductions in COMT abundance and activity, compared with wild-type mice, explicitly in the absence of off-target changes in the expression of other genes. Despite robust alterations in dopamine metabolism, we found only subtle changes on certain cognitive tasks under baseline conditions (eg, increased spatial novelty preference in COMT-Met mice vs wild-type mice). However, genotype differences emerged after administration of the COMT inhibitor tolcapone: performance of

3H]Benzophenone Photolabeling Identifies State-Dependent Changes in Nicotinic Acetylcholine Receptor Structure3H]Benzophenone Photolabeling Identifies State-Dependent Changes in Nicotinic Acetylcholine Receptor Structure
Interactions of benzophenone (BP) with the Torpedo nicotinic acetylcholine receptor (nAChR) were characterized by electrophysiological analyses, radioligand binding assays, and photolabeling of nAChR-rich membranes with [3H]BP to identify the amino acids contributing to its binding sites. BP acted as a low potency noncompetitive antagonist, reversibly inhibiting the ACh responses of nAChRs expressed in Xenopus oocytes (IC50 = 600 卩 and the binding of the noncompetitive antagonist [3H]tetracaine to nAChR-rich membranes (IC50 = 150 卩. UV irradiation at 365 nm resulted in covalent incorporation of [3H]BP into the nAChR subunits (d , a ߠ, ?), with photoincorporation limited to the nAChR transmembrane domain. Comparison of nAChR photolabeling in the closed state (absence of agonist) and desensitized state (equilibrated with agonist) revealed selective desensitized state labeling in the d subunit of dPhe-232 in dM1 and dPro-286/dIle-288 near the beginning of dM3 that are within a pocket at the ...

By limiting your sunscreen choices to ones that contain the 3 essentials, youll still have quite a few options. To find a sunscreen thats right for you, youll want to consider your skins unique needs and where you want to apply the sunscreen.. The following list can help you narrow your options so that you can find a sunscreen thats right for you.. Acne-prone skin: Look for the words non-comedogenic or wont clog pores.. Allergy-prone skin: Avoid sunscreen that contains fragrance, PABA, parabens, or oxybenzone (benzophenone-2, benzophenone-3, diosybenzone, mexenone, sulisobenzone, or sulisobenzone sodium).. Around your eyes: To prevent sunscreen from dripping into your eyes, use a sunscreen stick around your eyes. Make sure the stick has an SPF 30 (or higher), broad-spectrum protection, and water resistance.. Children: Use a sunscreen made for children. Most contain zinc oxide and titanium dioxide.. Dry skin: Look for moisturizing or dry skin on the label.. Lips: Lip balm with SPF ...

In this research intermolecular and intramolecular triplet sensitization has been employed to photochemically generate triplet alkyl nitrene intermediates in solution. Photolyzing with light greater than 300 nm assures that only the ketone chromophore is exclusively excited to its triplet excited state. Once generated, the ketone can transfer its triplet energy to the azide moiety which loses molecular nitrogen to give a triplet alkyl nitrene intermediate. Intermolecular triplet sensitization in solution allowed trapping of triplet alkyl nitrene intermediates via bimolecular reactions. Photolysis of 1-azidoadamantane in solution with acetophenone, benzophenone and acetone led to an azo-dimer as the major product. This product comes from dimerization of two triplet alkyl nitrenes. Intermolecular sensitized photolysis of benzyl azide led to N-methyleneaniline as the major photoproduct with acetophenone as the triplet sensitizer. With benzophenone as the triplet sensitizer the major product was ...

Benzophenones chemicals found in some sunscreen and nail polish has been linked to endometriosis, according to a new study.. Not surprisingly, the industry group the Personal Care Products Council faulted the study calling it weak and unconvincing, said WebMD. The study is published in Environmental Science & Technology and found that some chemicals broadly used in sunscreens, nail polish, and other consumer products-because of their UV protecting properties-are linked to increased risks for developing endometriosis.. Endometriosis is a painful gynecological condition in which uterine tissue grows outside the uterus, typically on the exterior of the uterus and into the abdomen near the ovaries or fallopian tubes. The tissue reacts as if it were within the uterus, thickening and shedding monthly with a womans menstrual cycle, explained WebMD. The condition can lead to scarring and infertility and affects about one in 10 women. Studies suggest that the condition is on the rise.. The research ...

COMT Val(158)Met genotype determines the direction of cognitive effects produced by catechol-O-methyltransferase inhibition. -...COMT Val(158)Met genotype determines the direction of cognitive effects produced by catechol-O-methyltransferase inhibition. -...
BACKGROUND: Catechol-O-methyltransferase (COMT) metabolizes dopamine. The COMT Val(158)Met polymorphism influences its activity, and multiple neural correlates of this genotype on dopaminergic phenotypes, especially working memory, have been reported. COMT activity can also be regulated pharmacologically by COMT inhibitors. The inverted-U relationship between cortical dopamine signaling and working memory predicts that the effects of COMT inhibition will differ according to COMT genotype. METHODS: Thirty-four COMT Met(158)Met (Met-COMT) and 33 COMT Val(158)Val (Val-COMT) men were given a single 200-mg dose of the brain-penetrant COMT inhibitor tolcapone or placebo in a randomized, double-blind, between-subjects design. They completed the N-back task of working memory and a gambling task. RESULTS: In the placebo group, Met-COMT subjects outperformed Val-COMT subjects on the 2- back, and they were more risk averse. Tolcapone had opposite effects in the two genotype groups: it worsened N-back performance

Structure-based Design Of Benzophenone Inhibitors Targeting Enoyl-ACP Reductase EnzymeStructure-based Design Of Benzophenone Inhibitors Targeting Enoyl-ACP Reductase Enzyme
Mycobacterium leprae is the causative agent of the disease, leprosy. As M. leprae develops resistance against most of the drugs, novel drug targets are required in order to design new drugs. The present study is aimed at finding the active site of the protein, which is used as a strategy in drug design. Enoyl-acyl carrier protein reductase is one of the receptor proteins used in drug discovery for screening anti-leprosy agents. The crystal structure of the inhibited M. leprae InhA complex PDB ID: 2NTV provide the details of protein-ligand interactions. Series of compounds having benzophenone moiety were designed. The virtually designed drug candidates have docked well in the active site region of the protein. The prediction of ADME properties was also performed by Qikprop software ...

In 1967, Norrish and Porter were honoured with Nobel prize for their seminal work on understanding the fast chemical reactions using flash photolysis technique.1 Since then benzophenone (Bzp) serves as an archetypal system for understanding the photochemistry of various aromatic ketones. Aromatic ketones find their use in various technologically significant applications like sunscreen, photocatalysis, etc., apart from their fundamental interest.2 Efficacy of aromatic ketones for use in various applications relies upon their photophysics and photochemistry. Therefore, understanding the photophysics and photochemistry of Bzp has attracted several experimental and theoretical investigations.2 Despite these myriads of investigations, pathways for populating the lowest triplet state (T1) after photoexcitation to the S1 state remains still elusive. There are two plausible pathways: i) a direct ISC from S1(nπ*) to T1(nπ*); or ii) an indirect process, involving ISC from S1(nπ*) to T1(ππ*) with ...

Bromfenac - WikipediaBromfenac - Wikipedia
Bromfenac is a nonsteroidal anti-inflammatory drug (NSAID) marketed in the US as an ophthalmic solution (current brand names Prolensa and Bromday, prior formulation brand name Xibrom, which has since been discontinued) by ISTA Pharmaceuticals for short-term, local use. Prolensa and Bromday are the once-daily formulation of bromfenac, while Xibrom was approved for twice-daily administration. In Europe, the trade name is Yellox. Bromfenac is indicated for the treatment of ocular inflammation and pain after cataract surgery. The FDA and European approvals for bromfenac are for use one day before and two weeks following cataract surgery for the treatment of ocular inflammation and pain. The drug has been shown to reduce macular edema and thickness of the retina (an indicator for inflammation) and improve visual acuity after surgery. Bromfenac is contraindicated for people with adverse reactions to NSAIDs, such as asthma or rashes. Bromfenac eye drops are generally well tolerated. Comparatively ...

Bitter Kola - Elan League InternationalBitter Kola - Elan League International
Garcinia kola (Family Guttifereae) known as bitter kola is a highly valued ingredient in African traditional medicine. The plant is cultivated largely in West Africa for its edible fruit and seeds which has been employed in folk medicine as rejuvenating agent and general antidote. Bitter cola seeds have been shown to contain a complex mixture of biflavonoids, prenylated benzophenones and xanthones.. Many pharmacological effects have been demonstrated for Garcinia biflavonoids, among them are antiviral, anti-inflammatory, antidiabetic, bronchodilator, antihepatotoxic properties, other studies show that antimicrobial activity was due to polyisoprenylated benzophenone. Some proprietary dietary supplements containing Garcinia kola extractives already exist in US and African markets.. ...

The first objective of this thesis was to investigate effects of endocrine disruptors on the developing brain and gonads of bird embryos. The substances studied were the insecticide methoxychlor, and nine UV-filters (3-benzylidene camphor (3BC), 4 methyl benzylidene camphor (4MBC), benzophenone (BP) 1,2 and 3, 4 hydroxy benzophenone (4 HB), 4 dihydroxy benzophenone (4DHB), benzyl salicylate (BS), and ethyl-4-aminobenzoate Et-PABA)), commonly used in cosmetic products. Some of these substances have no estrogenic effect in vitro, but have been shown to be estrogenic in vivo. The PCB-mixture Clophen A50 is a well-known inducer of biotransformation enzymes and was co-administered with methoxychlor and the UV-filters 3BC and 4MBC.. Exposure to 3BC or 4MBC caused ovotestis formation and malformations of the Müllerian ducts in Japanese quail embryos. Co-exposure to one of these compounds and Clophen A50 enhanced the effects, indicating that Clophen A50 potentiates the effects of the UV-filters. ...

Modulation of hippocampal dopamine metabolism and hippocampal-dependent cognitive function by catechol-O-methyltransferase...Modulation of hippocampal dopamine metabolism and hippocampal-dependent cognitive function by catechol-O-methyltransferase...
Catechol-O-methyltransferase (COMT) catabolises the catecholamine neurotransmitters and influences cognitive function. COMT modulates dopamine levels in the prefrontal cortex and its action in this region is generally invoked to explain its effects on cognition. However, its role in other brain regions important for cognitive function remains largely unexplored. Here, we investigated COMTs impact on dopamine metabolism in the hippocampus and hippocampal-dependent behaviour. We examined the acute effects of a centrally-acting COMT inhibitor, tolcapone (30 mg/kg i.p.), on dopamine metabolism in the rat dorsal hippocampus, assessed both in tissue homogenates and extracellularly, using in vivo microdialysis. Additionally, we investigated the effect of tolcapone on delayed-rewarded alternation and spatial novelty preference, behavioural tasks which are dependent on the dorsal hippocampus. Tolcapone significantly modulated dopamine metabolism in the dorsal hippocampus, as indexed by the depletion of

There are concerns that developmental exposure to endocrine disrupting chemicals such as phenolic compounds and phthalates could affect child cognitive function. Epidemiological studies tackling this question have mainly focused on phthalate metabolites and bisphenol A, but not on the other phenolic compounds. Our study aimed to assess the relationship between in-utero exposure to phthalates, bisphenol A and other phenolic compounds (parabens, triclosan, dichlorophenols and benzophenone-3) and the Intelligence Quotient (IQ) of boys at 5-6 years. In 452 mother-son dyads from the French EDEN cohort, we measured 11 phthalate metabolites and 9 phenolic compounds (4 parabens, benzophenone-3, bisphenol A, 2 dichlorophenols and triclosan) in spot urine samples collected between 22 and 29 gestational weeks. Verbal and performance IQ of children were assessed at 5-6 years by a psychologist using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). We used adjusted Structural Equation Models (SEM)

Weatherable polycarbonate compositions (formulations or blends) comprise polycarbonate, cycloaliphatic polyester resins, at least one of a benzotriazole, benzophenone, and triazine based UVA, and a catalyst quencher. The incorporation of the cycloaliphatic polyester resin and the benzotriazole, benzophenone, and triazine based UVA exhibits a synergistic effect, thereby resulting in unexpected enhanced protection of the polycarbonate compositions by imparting photostability to the polycarbonate formulations, thereby reducing yellowing or other forms of light induced degradation.

Previous activity-guided phytochemical studies on Garcinia buchananii stem bark, which is traditionally used in Africa to treat various gastrointestinal and metabolic illnesses, revealed xanthones, polyisoprenylated benzophenones, flavanone-C-glycosides, biflavonoids, and/or biflavanones as bioactive key molecules. Unequivocal structure elucidation of biflavonoids and biflavanones by means of NMR spectroscopy is often complicated by the hindered rotation of the monomers around the C-C axis (atropisomerism), resulting in a high spectral complexity. In order to facilitate an unrestricted rotation, NMR spectra are usually recorded at elevated temperatures, commonly over 80 degrees C, which effects in a single set of resonance signals. However, under these conditions, one of the target compounds of this investigation, (2R,3S,2R,3R)-manniflavanone (1), undergoes degradation. Therefore, we demonstrated in the present study that the 1,1-ADEQUATE could be successfully used as a powerful alternative ...

Skin diseases caused by sun exposure include melanoma, basal cell carcinoma, squamous cell carcinoma, photoaging, as well as sunburn and many other conditions. According to the Skin Cancer Foundation, skin cancer is the most common type of cancer in the US. The vast majority of mutations found in melanoma, according to a 2009 study published in Nature [1], are caused by UV radiation.. Currently, commercial sunscreens are composed of physical sunblocks including zinc oxide and titanium dioxide, and chemical UV (ultraviolet lights) absorbers/filters such as octinoxate for UVB and benzophenone for UVA. The compositions of commercial sunscreen products are disclosed by the manufacturer and regulated by the health product regulatory authorities such the FDA in the US. The UV absorbers/filters are organic chemicals that absorb UV lights within a very limited range of wavelength. Consequently, a combination of different chemicals is needed to achieve broad-spectrum protection.. Currently the FDA ...

In this paper, the improvement over a novel format for selective solid-phase extraction based on a molecularly imprinted polymer (MIP) is described. A small amount of MIP has been synthesized within the superficial pores of commercial polyethylene (PE) frits and attached to its surface using benzophenone (BP), a photo-initiator capable to start the polymerization from the surface of the support material. Key properties affecting the obtainment of a proper polymeric layer, such as polymerization time and kind of cross-linker were optimized. Prepared composite material was applied to the SPE of TBZ in real samples extracts, showing an impressive clean-up ability. Calibrations showed good linearity in the concentration range of 0.05-5.00 μg g-1, referred to the original solid sample, and the regression coefficients obtained were greater than 0.998. The calculated detection limit was 0.01 μg g-1, low enough to satisfactory analysis of TBZ in real samples. Mean recoveries were about 70 % at ...

Single-Step Covalent Functionalization of Polylactide Surfaces - OpenThesisSingle-Step Covalent Functionalization of Polylactide Surfaces - OpenThesis
Degradable polymers have gained an increased attention in the field of biomedical applications over the past decades, for example in tissue engineering. One way of improving the biocompatibility of these polymers is by chemical surface modification, however the risk of degradation during the modification procedure is a limiting factor. In some biomedical applications, for example in nerve guides, a patterned surface is desired to improve the cell attachment and proliferation.In this thesis a new non-destructive, single-step, and solvent free method for surface modification of degradable polymers is described. Poly(L-lactide) (PLLA) substrates have been functionalized with one of the following vinyl monomers; N-vinylpyrrolidone (VP), acrylamide (AAm), or maleic anhydride (MAH) grafts. The substrates were subjected to a vapor phase atmosphere constituted of a mixture of a vinyl monomer and a photoinitiator (benzophenone) in a closed chamber at very low pressure and under UV irradiation. ...

Triethanolamine (1), N-methyldiethanolamine (2) and N,N-dimethylethanolamine (3) have been used in conjunction with the 2-(2-chlorophenyl)-4,5-diphenylimidazolyl radical and triplet benzophenone to initiate the polymerisation of lauryl acrylate. The radical abstracts a hydrogen atom from the amine to generate an alpha-aminoalkyl radical. From the order of reactivity of the amines towards the lophyl (triarylimidazolyl) radical i.p. 2 ,, 1 , 3 it is concluded that hydrogen-atom abstraction occurs rather than electron followed by proton transfer. The imidazolyl radicals abstract hydrogen from thiols in a similar fashion more effectively to give thiyl radicals which initiate polymerisation of the acrylate. By following the progress of the polymerisation reactions by RTIR spectroscopy, it was concluded that the effectiveness of the amines to reduce oxygen inhibition is 1 , 3 , 2. The ability of the amines to act as synergists in the polymerisation of thin films of lauryl acrylate initiated by lophyl ...

Oxybenzone was investigated by NTP (National Toxicology Program, US) for subchronic toxicity towards rats and mice by using oral and dermal exposure. Systemic effects were seen in rats and a NOAEL oral of 393 mg/kg bw/d (females) and 429 mg/kg bw/d males) respectively was derived. The NOAEL found with mice was more than a magnitude higher (7579 mg/kg bw/d females and 5981 mg/kg bw/d males) but also showed liver and kidneys being the target organ. Also the dermal route was investigated for both species and the NOAEL was set to 200 mg/kg bw/d as systemic availability by dermal route was limited and hardly any effects were seen at the high dose of 200 mg/kg bw/d and also no local effects were observed in the subchronic dermal studies. A 27 -day subacute study on rats by oral exposure resulted in a higher NOAEL but was limited in parameters observed. A NOAEL of 200 mg/kg body weight was identified in the developmental study. Given the next highest dose in the study was 1000 mg/kg body weight the use ...
