Sex-related differences in urinary excretion of egualen sodium in rats. (1/33)

Egualen sodium (sodium 3-ethyl-7-isopropyl-1-azulenesulfonate 1/3 hydrate) is a new antiulcer drug. There has been no difference observed in absorption between male and female rats, the relative amount of metabolites in male plasma has been higher than that in females, and the excretion ratios of metabolites in males have been significantly higher than those in females. However, the plasma concentration profile of total radioactivity in males has been higher than that in females. To clarify this discrepancy, the renal clearances and plasma concentrations of the unchanged drug and its metabolites were determined. The renal clearance of the unchanged drug in males was 21 times lower than that in females, and the urinary excretions in males and females were 2.1 and 39.5% of dose, respectively. This indicates that the major factor in the sex-related difference observed in the plasma concentration of total radioactivity is due to the difference in the renal clearance of the unchanged drug between the sexes. The results of treatments with probenecid in normal and gonadectomized rats revealed that egualen sodium was mainly excreted into urine by secretion through the renal tubule. Furthermore, the results of treatments with testosterone in rats revealed that the excretion of egualen sodium was highly affected by androgens. These facts indicated that the sex-related difference observed in the plasma concentration of total radioactivity can be attributed to the inhibition of renal tubular secretion of the unchanged drug by androgens. This is the first example of sex-related differences in both metabolism and excretion.  (+info)

Bicarbonate enhances peroxidase activity of Cu,Zn-superoxide dismutase. Role of carbonate anion radical and scavenging of carbonate anion radical by metalloporphyrin antioxidant enzyme mimetics. (2/33)

Much evidence exists for the increased peroxidase activity of copper, zinc superoxide dismutase (SOD1) in oxidant-induced diseases. In this study, we measured the peroxidase activity of SOD1 by monitoring the oxidation of dichlorodihydrofluorescein (DCFH) to dichlorofluorescein (DCF). Bicarbonate dramatically enhanced DCFH oxidation to DCF in a SOD1/H(2)O(2)/DCFH system. Peroxidase activity could be measured at a lower H(2)O(2) concentration ( approximately 1 microm). We propose that DCFH oxidation to DCF is a sensitive index for measuring the peroxidase activity of SOD1 and familial amyotrophic lateral sclerosis SOD1 mutants and that the carbonate radical anion (CO(3)) is responsible for oxidation of DCFH to DCF in the SOD1/H(2)O(2)/bicarbonate system. Bicarbonate enhanced H(2)O(2)-dependent oxidation of DCFH to DCF by spinal cord extracts of transgenic mice expressing SOD1(G93A). The SOD1/H(2)O(2)/HCO(3)(-)-dependent oxidation was mimicked by photolysis of an inorganic cobalt carbonato complex that generates CO(3). Metalloporphyrin antioxidants that are usually considered as SOD1 mimetic or peroxynitrite dismutase effectively scavenged the CO(3) radical. Implications of this reaction as a plausible protective mechanism in inflammatory cellular damage induced by peroxynitrite are discussed.  (+info)

Synthesis of new azulene derivatives and study of their effect on lipid peroxidation and lipoxygenase activity. (3/33)

The relationship between free radicals and acute or chronic inflammation has been well established. We have previously reported the significant antioxidant activity of the natural azulene derivatives chamazulene and guaiazulene. Furthermore, some synthetic azulene analogues have been found to possess anti-inflammatory activity. In this investigation we report the synthesis of five 3-alkyl or 3-(hydroxy)alkylazulene-1-carboxylic acids and esters, from tropolone, via the corresponding furanone. The synthesised compounds were tested for their effect on the peroxidation of rat hepatic microsomal membrane lipids, applying the 2-thiobarbituric acid test. Their anti-inflammatory activity was evaluated in vitro by the offered inhibition of soybean lipoxygenase. All the tested molecules were found to inhibit lipid peroxidation by 100% at 1 mM. They were also found to considerably inhibit lipoxygenase activity. The above results are discussed in relation to the structure and physicochemical properties of the examined azulene derivatives.  (+info)

Cardiovascular effects of orally administered HNS-32, an originally synthesized azulene-1-carboxamidine derivative, assessed in the in vivo rat model. (4/33)

HNS-32, an azulene-1-carboxamidine derivative, is an originally synthesized antiarrhythmic compound. Its cardiovascular effects after oral administration (1-10 mg/kg) were assessed using the pentobarbital-anesthetized in vivo rat model in comparison with those of verapamil (3 mg/kg, p.o.). Verapamil decreased the heart rate and mean blood pressure and prolonged the PR interval without changing the QRS width (n = 6). Similar results were observed for HNS-32 except that the QRS width was prolonged by the highest dose and the effects occurred slowly and lasted longer. These results suggest that HNS-32 is an orally active slowly-acting calcium plus sodium channel blocker.  (+info)

Radiosensitization and DNA repair inhibition by the combined use of novel inhibitors of DNA-dependent protein kinase and poly(ADP-ribose) polymerase-1. (5/33)

The DNA repair enzymes, DNA-dependent protein kinase (DNA-PK) and poly(ADP-ribose) polymerase-1 (PARP-1), are key determinants of radio- and chemo-resistance. We have developed and evaluated novel specific inhibitors of DNA-PK (NU7026) and PARP-1 (AG14361) for use in anticancer therapy. PARP-1- and DNA-PK-deficient cell lines were 4-fold more sensitive to ionizing radiation (IR) alone, and showed reduced potentially lethal damage recovery (PLDR) in G(0) cells, compared with their proficient counterparts. NU7026 (10 micro M) potentiated IR cytotoxicity [potentiation factor at 90% cell kill (PF(90)) = 1.51 +/- 0.04] in exponentially growing DNA-PK proficient but not deficient cells. Similarly, AG14361 (0.4 micro M) potentiated IR in PARP-1(+/+) (PF(90) = 1.37 +/- 0.03) but not PARP-1(-/-) cells. When NU7026 and AG14361 were used in combination, their potentiating effects were additive (e.g., PF(90) = 2.81 +/- 0.19 in PARP-1(+/+) cells). Both inhibitors alone reduced PLDR approximately 3-fold in the proficient cell lines. Furthermore, the inhibitor combination completely abolished PLDR. IR-induced DNA double strand break (DNA DSB) repair was inhibited by both NU7026 and AG14361, and use of the inhibitor combination prevented 90% of DNA DSB rejoining, even 24-h postirradiation. Thus, there was a correlation between the ability of the inhibitors to prevent IR-induced DNA DSB repair and their ability to potentiate cytotoxicity. Thus, individually, or in combination, the DNA-PK and PARP-1 inhibitors act as potent radiosensitizers and show potential as tools for anticancer therapeutic intervention.  (+info)

Photomutagenicity of cosmetic ingredient chemicals azulene and guaiazulene. (6/33)

The photomutagenicity of the popular skin conditioning agents azulene and guaiazulene were tested in Salmonella typhimurium TA98, TA100 and TA102. Following irradiation with UVA and/or visible light, both azulene and guaiazulene exhibited mutagenicity 4-5-fold higher than the spontaneous background mutation. In contrary, naphthalene, a structural isomer of azulene, was not photomutagenic under the same conditions. Azulene was photomutagenic when irradiated with UVA light alone, visible light alone, or a combination of UVA and visible light. Azulene and guaiazulene are not mutagenic when the experiment is conducted with the exclusion of light. Therefore, extreme care must be taken when using cosmetic products with azulene/guaiazulene as ingredients since after applying these products on the skin, exposure to sunlight is inevitable.  (+info)

Anticancer chemosensitization and radiosensitization by the novel poly(ADP-ribose) polymerase-1 inhibitor AG14361. (7/33)

BACKGROUND: Poly(ADP-ribose) polymerase-1 (PARP-1) facilitates the repair of DNA strand breaks. Inhibiting PARP-1 increases the cytotoxicity of DNA-damaging chemotherapy and radiation therapy in vitro. Because classical PARP-1 inhibitors have limited clinical utility, we investigated whether AG14361, a novel potent PARP-1 inhibitor (inhibition constant <5 nM), enhances the effects of chemotherapy and radiation therapy in human cancer cell cultures and xenografts. METHODS: The effect of AG14361 on the antitumor activity of the DNA alkylating agent temozolomide, topoisomerase I poisons topotecan or irinotecan, or x-irradiation or gamma-radiation was investigated in human cancer cell lines A549, LoVo, and SW620 by proliferation and survival assays and in xenografts in mice by tumor volume determination. The specificity of AG14361 for PARP-1 was investigated by microarray analysis and by antiproliferation and acute toxicity assays in PARP-1-/- and PARP-1+/+ cells and mice. After intraperitoneal administration, the concentration of AG14361 was determined in mouse plasma and tissues, and its effect on PARP-1 activity was determined in tumor homogenates. All statistical tests were two-sided. RESULTS: AG14361 at 0.4 micro M did not affect cancer cell gene expression or growth, but it did increase the antiproliferative activity of temozolomide (e.g., in LoVo cells by 5.5-fold, 95% confidence interval [CI] = 4.9-fold to 5.9-fold; P =.004) and topotecan (e.g., in LoVo cells by 1.6-fold, 95% CI = 1.3-fold to 1.9-fold; P =.002) and inhibited recovery from potentially lethal gamma-radiation damage in LoVo cells by 73% (95% CI = 48% to 98%). In vivo, nontoxic doses of AG14361 increased the delay of LoVo xenograft growth induced by irinotecan, x-irradiation, or temozolomide by two- to threefold. The combination of AG14361 and temozolomide caused complete regression of SW620 xenograft tumors. AG14361 was retained in xenografts in which PARP-1 activity was inhibited by more than 75% for at least 4 hours. CONCLUSION: AG14361 is, to our knowledge, the first high-potency PARP-1 inhibitor with the specificity and in vivo activity to enhance chemotherapy and radiation therapy of human cancer.  (+info)

Novel poly(ADP-ribose) polymerase-1 inhibitor, AG14361, restores sensitivity to temozolomide in mismatch repair-deficient cells. (8/33)

PURPOSE: Mismatch repair (MMR) deficiency confers resistance to temozolomide, a clinically active DNA-methylating agent. The purpose of the current study was to investigate the reversal mechanism of temozolomide resistance by the potent novel poly(ADP-ribose) polymerase (PARP)-1 inhibitor, AG14361, in MMR-proficient and -deficient cells. EXPERIMENTAL DESIGN: The effects of AG14361, in comparison with the methylguanine DNA methyltransferase inhibitor, benzylguanine, on temozolomide-induced growth inhibition were investigated in matched pairs of MMR-proficient (HCT-Ch3, A2780, and CP70-ch3) and -deficient (HCT116, CP70, and CP70-ch2) cells. RESULTS: AG14361 enhanced temozolomide activity in all MMR-proficient cells (1.5-3.3-fold) but was more effective in MMR-deficient cells (3.7-5.2-fold potentiation), overcoming temozolomide resistance. In contrast, benzylguanine only increased the efficacy of temozolomide in MMR-proficient cells but was ineffective in MMR-deficient cells. The differential effect of AG14361 in MMR-deficient cells was not attributable to differences in PARP-1 activity or differences in its inhibition by AG14361, nor was it attributable to differences in DNA strand breaks induced by temozolomide plus AG14361. MMR-deficient cells are resistant to cisplatin, but AG14361 did not sensitize any cells to cisplatin. PARP-1 inhibitors potentiate topotecan-induced growth inhibition, but AG14361 did not potentiate topotecan in MMR-deficient cells more than in MMR-proficient cells. CONCLUSIONS: MMR defects are relatively common in sporadic tumors and cancer syndromes. PARP-1 inhibition represents a novel way of selectively targeting such tumors. The underlying mechanism is probably a shift of the cytotoxic locus of temozolomide to N(7)-methylguanine and N(3)-methyladenine, which are repaired by the base excision repair pathway in which PARP-1 actively participates.  (+info)

Distinctive lessons of bioactive constituents are current in chamomile, which have been isolated and made use of as medicinal preparations and cosmetics (nine). The plant is made up of 0.24%-1.nine% unstable oil, made up of a range of different oils. When subjected to steam distillation, the oil ranges in color from excellent blue to deep eco-friendly when new but turns to darkish yellow following storage. Even with fading, the oil does not drop its potency. About one hundred twenty secondary metabolites are already identified in chamomile, including 28 terpenoids and 36 flavonoids (ten, 11). The principal parts of your critical oil extracted from your German chamomile bouquets would be the terpenoids α-bisabolol and its oxide azulenes including chamazulene and acetylene derivatives. Chamazulene and bisabolol are extremely unstable and therefore are very best preserved in an alcoholic tincture. The vital oil of Roman chamomile contains fewer chamazulene and is principally constituted from ...

Electron transfer reactions have been studied between 9-anthracenecarboxylic acid co-adsorbed with perylene on silica gel surfaces employing azulene as a molecular shuttle in order to facilitate hole transfer. In this paper we present for the first time a ternary system that unambiguously demonstrates an appreciable mobility of radical cations on the silica gel surface. Rates of hole transfer from the 9-anthracenecarboxylic acid radical cation to perylene via azulene have been studied using diffuse reflectance laser flash photolysis spectroscopy. Azulene has been shown to enhance the rate of electron transfer in the ternary system, proving significant mobility of the azulene and its radical cation species on silica gel surfaces. The data shows that the azulene radical cation can diffuse at an appreciable rate on the silica gel surface ...

Abstract : Non-viral gene carriers for safe and efficient gene transfection have become of particular interest among researchers of different disciplines ranging from physical chemistry to biotechnology. Recently polymeric vectors have been extensively studied as potentially new gene transfer agents. Until now most of the research efforts were made to optimize the gene-to-polymer weight ratio of polyplexes for safe and efficient gene transfection. In this work, we report on the development of novel poly(allylamine) derivatives with different balance of the primary, secondary, tertiary, and quaternary amino groups. All derivatives were able to complex pDNA into polyplexes at low gene-to-polymer weight ratios i.e., 1:1 or 1:2. Moreover, the examined polyplexes were less cytotoxic and showed better transfection efficiency when compared to linear poly(ethyleneimine). These results indicate that the presence of quaternary ammonium groups is important in the formation of stable polyplexes. Polymers ...

Significant digging around on the Internet didnt reveal to me what Yulan Oil is or where it comes from. There is a Yulan Magnolia tree but whether this oil comes from that, I couldnt tell you. Its also not listed in the ingredients (which are Glycerin, Azulene, Collogen amino acids, Hyaluronic acid, Niacinamide, Gold, Morus Alba extract, Carbomer, Proplyene glycol, Purified Water) - But the Morus Alba is a white mullberry extract, which is good for skin, along with Hyraluronic Acid which is recommended for all sorts of discolouration - its not hard to see why this would work ...
La terapia génica presenta potenciales aplicaciones terapéuticas para el tratamiento de muchas enfermedades como el cáncer, enfermedades monogénicas, enfermedad vascular, entre otras. Aunque la mayoría de protocolos de terapia génica empleen vectores virales, debido a su alta eficacia de transfección, crecientes preocupaciones debido a su activación de respuesta inmunológica motivan al desarrollo de sistemas de transportes no virales que sean seguros y eficaces. Poli(β-aminoestere)s (pBAEs) son prometedores vectores no virales debido a que su naturaleza de poliéster resulta en un atractivo perfil de biocompatibilidad debido a su alta biodegradabilidad y baja toxicidad. Este trabajo desarrolla una nueva familia de pBAEs, los cuales presentan oligopéptidos terminales, capaces de condensar tanto ADN como siRNA en partículas de tamaño nanométrico. En primer lugar, se realizan experimentos in vitro para evaluar la habilidad de estos nuevos pBAEs para transportar eficazmente tanto DNA ...
The overall aim of the study was to determine the passive prophylatic effect of bovine milk immunoglobulin administered orally either as a bolus (once a day) or as continuously (three times a day) against diarrhoea caused by Escherichia coli K 88. As the piglets have gastrointestinal structural and physiological similarities to humans they were assumed to be an appropriate model for the study. The first part of the study was done to evaluate the quantity of undigested immunoglobulin G in the gastrointestinal tract of the piglet. This was conducted in two experiments. One was a pilot study and the other was to estimate the quantity of undigested immunoglobulin G in the gut. A pilot study was conducted to evaluate the rate of movement and the quantities of digesta that can be collected in the gastrointestinal tract regions at varying time intervals. Ten piglets were randomly divided into five groups of two in each. One from each group was selected, fed with an experimental diet which contained ...

All it is is me and them, Morris told me. It simplifies the world, and were looking into each others eyes. Were sitting in a room as were sitting in a room now, looking at each other. And there is an intimacy that is much greater than doing a different kind of thing. And thats preserved, whether Im 20 feet away from them in the studio or 2,000 miles away from them on Skype. But Morris also made this statement about his predilection for electronic barriers and their socially prophylactic effect: I used to say being there is the next best thing to using the phone. Famous people whom Errol Morris has interviewed on the Interrotron include Mikhail Gorbachev, Al Sharpton, Iggy Pop, and former U.S. Secretary of Defense Robert McNamara, the subject of Morriss 2003 film, The Fog of War, who upon being introduced to the Interrotron told Morris, I dont care what you call it, I dont like it, and then sat down for what became several days of interviews anyway.

Poly (A) binding proteins are intimately implicated in controlling a number of events in mRNA metabolism from nuclear polyadenylation to cytoplasmic translation and stability. The known poly(A) binding proteins can be divided into three distinct structural groups (prototypes PABP1, PABPN1/PABP2 and Nab2p) and two functional families, showing that similar functions can be accomplished by differing structural units. This has prompted us to perform a screen for novel poly(A) binding proteins using Xenopus laevis. A novel poly(A) binding protein of 32 kDa (p32) was identified. Sequence analysis showed that p32 has about 50% identity to the known nuclear poly(A) binding proteins (PABPN1) but is more closely related to a group of mammalian proteins of unknown function. The expression of Xenopus laevis ePABP2 is restricted to early embryos. Accordingly, we propose that p32 is the founder member of a novel class of poly(A) binding proteins named ePABP2.
This randomised controlled study is the first RCT to evaluate the effects of G-CSF on the prevention of FN in patients with ovarian cancer. Treatment with G-CSF per physician discretion showed inferior outcomes for FN and myelosuppression. However, prophylactic treatment with short-acting G-CSF according to a stringent protocol would probably not result in such inferior outcomes. In a systematic review and meta-analysis, the weight of evidence from RCTs indicates little difference in efficacy between the short-acting and long-acting G-CSFs if dosed according to recommended guidelines. It was suggested long-acting G-CSFs in non-RCTs had greater efficacy, which may be a result of the underdosing of short-acting G-CSF in general practice in real-world usage.10 However, based on the findings of a systematic review of real-world comparative effectiveness studies, the risks of FN and FN-related complications are generally lower for prophylaxis with pegfilgrastim versus prophylaxis with short-acting ...

BaP's metabolites are mutagenic and highly carcinogenic, and it is listed as a Group 1 carcinogen by the IARC. Chemical agents and related occupations, Volume 10, A review of Human Carcinogens, IARC Monographs, Lyon France 2009 [13] In June 2016, BaP was added as benzo[def]chrysene to the REACH Candidate List of Substances of very high concern for Authorisation.[14] Numerous studies since the 1970s have documented links between BaP and cancers.[15] It has been more difficult to link cancers to specific BaP sources, especially in humans, and difficult to quantify risks posed by various methods of exposure (inhalation or ingestion).[citation needed] A link between vitamin A deficiency and emphysema in smokers was described in 2005 to be due to BaP, which induces vitamin A deficiency in rats.[16] A 1996 study provided molecular evidence linking components in tobacco smoke to lung cancer. BaP was shown to cause genetic damage in lung cells that was identical to the damage observed in the DNA of most ...
The structure of a PAH influences whether and how the individual compound is carcinogenic.[72][76] Some carcinogenic PAHs are genotoxic and induce mutations that initiate cancer; others are not genotoxic and instead affect cancer promotion or progression.[76][77] PAHs that affect cancer initiation are typically first chemically modified by enzymes into metabolites that react with DNA, leading to mutations. When the DNA sequence is altered in genes that regulate cell replication, cancer can result. Mutagenic PAHs, such as benzo[a]pyrene, usually have four or more aromatic rings as well as a "bay region", a structural pocket that increases reactivity of the molecule to the metabolizing enzymes.[78] Mutagenic metabolites of PAHs include diol epoxides, quinones, and radical PAH cations.[78][79][80] These metabolites can bind to DNA at specific sites, forming bulky complexes called DNA adducts that can be stable or unstable.[74][81] Stable adducts may lead to DNA replication errors, while unstable ...
In systematic chemical nomenclature, alkynes are named with the Greek prefix system without any additional letters. Examples include ethyne or octyne. In parent chains with four or more carbons, it is necessary to say where the triple bond is located. For octyne, one can either write 3-octyne or oct-3-yne when the bond starts at the third carbon. The lowest number possible is given to the triple bond. When no superior functional groups are present, the parent chain must include the triple bond even if it is not the longest possible carbon chain in the molecule. Ethyne is commonly called by its trivial name acetylene.. In chemistry, the suffix -yne is used to denote the presence of a triple bond. In organic chemistry, the suffix often follows IUPAC nomenclature. However, inorganic compounds featuring unsaturation in the form of triple bonds may be denoted by substitutive nomenclature with the same methods used with alkynes (i.e. the name of the corresponding saturated compound is modified by ...
There are two principal commercial uses of 1-MCP: maintaining the freshness of ornamental plants and flowers, and preventing the ripening of fruits. In each case, 1-MCP is combined with other materials for handling and then mixed with a specific amount of water or other solution to release it into the air.[9] It is used in enclosed indoor sites, such as coolers, truck trailers, greenhouses, storage facilities, and shipping containers.[9] Under the brand name EthylBloc, 1-MCP was approved by the U.S. Environmental Protection Agency for use on ornamental crops.[10] It is used with cut flowers, potted flowers, and bedding, nursery and foliage plants to prevent premature wilting, leaf yellowing, premature opening, and premature death.[11][12] Under the brand name SmartFresh, 1-MCP is used in the agriculture industry by growers, packers, and shippers to maintain the quality of fruits and vegetables by preventing or delaying the natural ripening process.
