Oligonucleotide-europium complex conjugate designed to cleave the 5' cap structure of the ICAM-1 transcript potentiates antisense activity in cells. (1/3714)

The 5' cap structure of mRNA is a N7 methylated guanosine residue that is linked by a 5'-5' triphosphate linkage to the 5'-terminus of cellular and viral RNAs synthesized by RNA polymerase II. This unique structure facilitates several processes of mRNA metabolism, including splicing, nucleocytoplasmic transport,initiation of translation, and degradation. Previous research has demonstrated that the lanthanide macrocycle complex, Eu(THED)3+, effectively cleaves the 5' cap structure of mRNA in solution by nucleophilic attack of the triphosphate linkage via the metal-activated hydroxyethyl group of the THED ligand. This report shows that attachment of a Eu(THED)3+analog to the 3'-terminus of an antisense oligonucleotide, which targets the 5'-terminus of the intercellular adhesion molecule 1 mRNA, potentiates the inhibitory activity of the antisense oligonucleotide in cytokine-treatedendothelial cells.  (+info)

Antimicrobial activities of synthetic bismuth compounds against Clostridium difficile. (2/3714)

Clostridium difficile is a major nosocomial pathogen responsible for pseudomembranous colitis and many cases of antibiotic-associated diarrhea. Because of potential relapse of disease with current antimicrobial therapy protocols, there is a need for additional and/or alternative antimicrobial agents for the treatment of disease caused by C. difficile. We have synthesized a systematic series of 14 structurally simple bismuth compounds and assessed their biological activities against C. difficile and four other gastrointestinal species, including Helicobacter pylori. Here, we report on the activities of six compounds that exhibit antibacterial activities against C. difficile, and some of the compounds have MICs of less than 1 microgram/ml. Also tested, for comparison, were the activities of bismuth subcitrate and ranitidine bismuth citrate obtained from commercial sources. C. difficile and H. pylori were more sensitive both to the synthetic bismuth compounds and to the commercial products than were Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis, and the last three species were markedly resistant to the commercial bismuth salts. Testing with human foreskin fibroblast cells revealed that some of the synthetic compounds were more cytotoxic than others. Killing curves for C. difficile treated with the more active compounds revealed rapid death, and electron microscopy showed that the bismuth of these compounds was rapidly incorporated by C. difficile. Energy dispersive spectroscopy X-ray microanalysis of C. difficile cells containing electron-dense material confirmed the presence of internalized bismuth. Internalized bismuth was not observed in C. difficile treated with synthetic bismuth compounds that lacked antimicrobial activity, which suggests that the uptake of the metal is required for killing activity. The nature of the carrier would seem to determine whether bismuth is transported into susceptible bacteria like C. difficile.  (+info)

Concatemerization of tRNA molecules in the presence of trivaline derivative. (3/3714)

The interaction of tRNA with trivaline dansyl hydrazide trifluoroacetate (DHTV) has been studied. The shape of curves of fluorimetric titration of tRNA with DHTV and vice versa can be explained only by formation of DHTV dimers on tRNA molecules, and subsequent association of DHTV-saturated tRNA molecules with each other. The ability of tRNA molecules to form concatemers in solution in the presence of DHTV has been demonstrated by electron microscopy. Electron microscopy of the tRNA-DHTV complexes stained with uranyl acetate revealed flexible rods 6-7 nm thick and up to several micrometers long.  (+info)

Determining anomericity of the glycosidic bond in Zn(II)-diethylenetriamine-disaccharide complexes using MSn in a quadrupole ion trap. (4/3714)

Zinc-diethylenetriamine (Zn-dien) N-glycoside complexes of four 1,4 and four 1,6 linked disaccharides are prepared. Each reaction mixture is ionized by electrospray and the resulting species [Zn(dien)(disaccharide)-H]+ is allowed to undergo collision-induced dissociation in a quadrupole ion trap. An MS3 analysis is used to differentiate alpha versus beta anomericity of the glycosidic bond in the disaccharide moiety. In addition, the MS2 and MS3 spectra can be used together to determine the linkage position of this glycosidic bond.  (+info)

Effects of vanadium complexes with organic ligands on glucose metabolism: a comparison study in diabetic rats. (5/3714)

1. Vanadium compounds can mimic actions of insulin through alternative signalling pathways. The effects of three organic vanadium compounds were studied in non-ketotic, streptozotocin-diabetic rats: vanadyl acetylacetonate (VAc), vanadyl 3-ethylacetylacetonate (VEt), and bis(maltolato)oxovanadium (VM). A simple inorganic vanadium salt, vanadyl sulphate (VS) was also studied. 2. Oral administration of the three organic vanadium compounds (125 mg vanadium element 1(-1) in drinking fluids) for up to 3 months induced a faster and larger fall in glycemia (VAc being the most potent) than VS. Glucosuria and tolerance to a glucose load were improved accordingly. 3. Activities and mRNA levels of key glycolytic enzymes (glucokinase and L-type pyruvate kinase) which are suppressed in the diabetic liver, were restored by vanadium treatment. The organic forms showed greater efficacy than VS, especially VAc. 4. VAc rats exhibited the highest levels of plasma or tissue vanadium, most likely due to a greater intestinal absorption. However, VAc retained its potency when given as a single i.p. injection to diabetic rats. Moreover, there was no relationship between plasma or tissue vanadium levels and any parameters of glucose homeostasis and hepatic glucose metabolism. Thus, these data suggest that differences in potency between compounds are due to differences in their insulin-like properties. 5. There was no marked toxicity observed on hepatic or renal function. However, diarrhoea occurred in 50% of rats chronically treated with VS, but not in those receiving the organic compounds. 6. In conclusion, organic vanadium compounds, in particular VAc, correct the hyperglycemia and impaired hepatic glycolysis of diabetic rats more safely and potently than VS. This is not simply due to improved intestinal absorption, indicating more potent insulin-like properties.  (+info)

Biodistribution, radiation dosimetry and pharmacokinetics of 111In-antimyosin in idiopathic inflammatory myopathies. (6/3714)

In view of the established role of 111In-antimyosin in the detection of heart muscle pathology, radiation dose estimates were made for this substance. Biodistribution and biokinetic data were obtained from our studies, which failed to show abnormal uptake of 111In-antimyosin in localized sites of skeletal muscle involvement in patients with idiopathic inflammatory myopathies. METHODS: After intravenous administration of 74 MBq (2 mCi) 111In-antimyosin, gamma camera scintigraphy was performed in 12 adult patients with inflammatory muscle disease and in 2 control patients. Six whole-body scans were performed over 72 h, and uptake of 111In-antimyosin in organs was quantified using an attenuation-corrected conjugate counting method. Residence times in source organs were used with MIRDOSE software to obtain radiation dose estimates. Pharmacokinetic parameters were derived from serial whole-blood and plasma 111In concentrations. RESULTS: The tracer cleared slowly from the circulation, and highest organ uptakes were found in the marrow and liver; kidneys showed the highest concentrations. Uptake was also evident in spleen, the facial image and male genitalia. CONCLUSION: For a typical administered activity of 74 MBq 111In-antimyosin, the kidneys receive the highest dose (58 mSv), and the effective dose is 11 mSv. Radioactivity was cleared from plasma at an average rate of 136 mL/h, and the mean steady-state distribution was approximately 5 L plasma.  (+info)

Oxidized low-density lipoprotein as a delivery system for photosensitizers: implications for photodynamic therapy of atherosclerosis. (7/3714)

Photodynamic therapy is a promising new strategy in the treatment of cardiovascular diseases. Photodynamic therapy for vascular diseases may be improved by the specific delivery of photosensitizers to the atherosclerotic lesion. In this study, we studied whether oxidatively modified low-density lipoprotein (OxLDL) could be used as a specific carrier for photosensitizers, thereby using the scavenger receptor expressed on macrophages as a target. The photosensitizer aluminum phthalocyanine chloride (AlPc) was incorporated into OxLDL, and its photodynamic effects were studied. Macrophages (RAW 264.7) were incubated with various concentrations of OxLDL-AlPc for different periods. After illumination of the cells with red light, cytotoxicity was observed that was dependent on the time of illumination and incubation. Macrophages incubated with OxLDL-AlPc that were not illuminated revealed no cytotoxicity. The uptake of the OxLDL-AlPc complexes was mediated by scavenger receptors expressed on macrophages. In the presence of the polyanion polyinosinic acid, a specific ligand for scavenger receptors, no cytotoxicity could be observed. Serum incubations of the OxLDL-AlPc complexes revealed that these complexes stay intact after incubation. No redistribution of AlPc to other plasma (lipo-) proteins could be detected, and 80-90% of the AlPc remained associated with the OxLDL particle. These results indicate that OxLDL may function as a specific delivery system for photosensitizers to the scavenger receptors expressed on the macrophages in the atherosclerotic lesion, increasing the beneficial effects of photodynamic therapy for cardiovascular diseases.  (+info)

In vitro cell cycle arrest, in vivo action on solid metastasizing tumors, and host toxicity of the antimetastatic drug NAMI-A and cisplatin. (8/3714)

The effects of NAMI-A (imidazolium trans-imidazoledimethyl sulfoxide-tetrachlororuthenate) are compared with cisplatin on tumor cells cultured in vitro at doses of 1 to 100 microM and on tumor metastases in vivo at maximum tolerated doses. Using mouse tumors that metastasize to the lungs, NAMI-A given i.p. for 6 consecutive days at 35 mg/kg/day, was effective independently of the tumor line being treated and of the stage of metastasis growth. Conversely, cisplatin (2 mg/kg/day for 6 days) was as effective as NAMI-A on MCa mammary carcinoma and TS/A adenocarcinoma and less effective than NAMI-A on Lewis lung carcinoma. Cisplatin reduced body weight gain and spleen weight during treatment and was much more toxic than NAMI-A on liver sinusoids, kidney tubules, and lung epithelium. In vitro NAMI-A caused a transient cell cycle arrest of tumor cells in the premitotic G2/M phase, whereas cisplatin caused a progressive dose-dependent disruption of cell cycle phases. Correspondingly, NAMI-A did not modify cell growth, whereas cisplatin caused a dose-dependent reduction of cell proliferation, as determined by sulforhodamine B test. Thus, NAMI-A, unlike cisplatin, is a potent agent for the treatment of solid tumor metastases as well as when these tumor lesions are in an advanced stage of growth. NAMI-A is endowed with a mechanism of action unrelated to direct tumor cell cytotoxicity, and such mechanism of action is responsible for a reduced host toxicity.  (+info)

Structure and hydrogen dynamic behavior in proton sponge cations and organometallic complexesStructure and hydrogen dynamic behavior in proton sponge cations and organometallic complexes
This thesis focuses on the study of hydrogen dynamic behavior in a series of proton sponge cations as well as in bis(silyl)hydride organometallic complexes. To understand the dynamic behavior, a new tool, i.e. the three-dimensional vibrational Schrödinger equation has been derived and solved. Three different vibrational patterns for hydrogen motion have been revealed. The classification of proton sponges and bis(silyl)hydride complexes into those with localized and delocalized hydrogen behavior has been proposed. For the organometallic complexes the influence of the vibrational motion of the hydrogen on J(Si−H) spin−spin coupling constants has been studied. Also this thesis presents a study of [Cp*Co(SiR3)2(H)2] cobalt complexes and their iridium analogues to detect possible Si···H interactions. Based on molecular geometries, Wiberg bond indices, and J(Si-H) spin-spin coupling constants, at least two residual Si···H interactions have been detected in cobalt complexes while there are ...

MetalloceneMetallocene
The general name metallocene is derived from ferrocene, (C5H5)2Fe or Cp2Fe , systematically named bis(η5-cyclopentadienyl)iron(II). According to the IUPAC definition, a metallocene contains a transition metal and two cyclopentadienyl ligands coordinated in a sandwich structure, i. e., the two cyclopentadienyl anions are co-planar with equal bond lengths and strengths. Using the nomenclature of hapticity, the equivalent bonding of all 5 carbon atoms of a cyclopentadienyl ring is denoted as η5, pronounced pentahapto. There are exceptions, such as uranocene, which has two cyclooctatetraene rings sandwiching a uranium atom.. In metallocene names, the prefix before the -ocene ending indicates what metallic element is between the Cp groups. For example in ferrocene, iron(II) or ferrous is present.. In contrast to the more strict definition proposed by IUPAC, which requires a d-block metal and a sandwich structure, the term metallocene and thus the denotation -ocene, is applied in the chemical ...

F-block metallocene - WikipediaF-block metallocene - Wikipedia
f-Block Metallocene refers to a class of organometallic sandwich compounds with f-Block metal and electron-rich ligands like cyclopentadienyl anion. The first prepared and well-characterized f-block metallocenes were the tris(cyclopentadienyl) lanthanide complexes, (C5H5)3Ln (Ln = La, Ce, Pr, Nd, Sm and Gd). However, their significance is limited more to their existences and structures than to their reactivity. The cyclopentadienyl ligands of f-block metallocenes were considered as inert ancillary ligands, only capable of enhancing their stability and solubility, but not their reactivity. In addition, only late and small metals in the lanthanide series, i.e., elements from Sm to Lu, are trivalent metallocene complexes, [(C5H5)2LnZ]n In 1980, the pentamethylcyclopentadienyl ligand, C5Me− 5, was introduced to prepare the lanthanide complexes with all metals in the series. Apart from improving the stability and solubility of the complexes, it was demonstrated to participate in organometallic ...

A bulky, optically active monoanionic scorpionate ligand, tris(4S-isopropyl-5,5-dimethyl-2-oxazolinyl)phenylborate (To P*), is synthesized from the naturally occurring amino acid l-valine as its lithium salt, Li[To P*] (1). That compound is readily converted to the thallium complex Tl[To P*] (2) and to the acid derivative H[To P*] (3). Group 7 tricarbonyl complexes To P*M(CO) 3 (M = Mn (4), Re (5)) are synthesized by the reaction of MBr(CO) 5 and Li[To P*] and are crystallographically characterized. The ν CO bands in their infrared spectra indicate that π back-donation in the rhenium compounds is greater with To P* than with non-methylated tris(4S-isopropyl-2-oxazolinyl)phenylborate (To P). The reaction of H[To P*] and ZnEt 2 gives To P*ZnEt (6), while To P*ZnCl (7) is synthesized from Li[To P*] and ZnCl 2. The reaction of To P*ZnCl and KOtBu followed by addition of PhSiH 3 provides the zinc hydride complex To P*ZnH (8). In this study, compound 8 is the first example of a crystallographically ...

The results show organometallic complexes Ln(C|sub|8|/sub|H|sub|8|/sub|)|sub|2|/sub||sup|¯|/sup| are typical sandwich structure. Both Eu(C|sub|8|/sub|H|sub|8|/sub|)|sub|2|/sub||sup|¯|/sup| and Ho(C|sub|8|/sub|H|sub|8|/sub|)|sub|2|/sub||sup|¯|/sup| have perfect sandwich structure with high D8h point symmetry. Nd(C|sub|8|/sub|H|sub|8|/sub|)|sub|2|/sub||sup|¯|/sup| and Yb(C|sub|8|/sub|H|sub|8|/sub|)|sub|2|/sub||sup|¯|/sup| possess D|sub|4h|/sub| point symmetry. Ce(C|sub|8|/sub|H|sub|8|/sub|)|sub|2|

Several cobalt complexes with tripodal chelating ligands Tp and Tp* (Tp = tris(pyrazolyl)borate; Tp* = tris(3,5-dimethyl-pyrazolyl)borate) were synthesized by treating the homoscorpionates of the first generation with CoBr2 under different conditions. These complexes were characterized with X-ray crystallographic determination as well as IR, NMR, MS, and UV-vis spectroscopies. Reaction of KTp with CoBr2 in THF afforded an unprecedented trinuclear Co(II) complex [TpCo(Hpz)Br]2(CoBr2) (1) with Tp as terminal ligands, as well as an oxidized side-product (Tp2Co)(Co2Br6) (2). The terminal Co(II) centers of (1) are octahedrally coordinated while the Co(II) in the bridging unit has a distorted tetrahedral geometry, holding a neighboring Co···Co distance of 3.472 Å. Reaction of KTp* with CoBr2 afforded half-sandwich Tp*CoBr (4) with pseudotetrahedrally coordinated Co(II) center, which is accessible to other donors. Mononuclear Tp*CoSPh (7) and dinuclear (Tp*Co)2O2(pz)2 (8) were prepared through ...

Organometallic chemistry, rigorously defined by the chemical synthesis and reactivity of molecules with metal-carbon bonds, is a vibrant area of research with a large variety of practical applications [1]. For example, organometallic complexes are commonly used as catalysts for the production of commodity chemicals, materials such as polymers, and in fine chemical synthesis and medicinal chemistry discovery [1,2]. The majority of discoveries in the area have been performed in the solution phase, with studies in the solid state generally often reserved only for structural analysis; for example, single-crystal X-ray crystallography and, to a significantly lesser extent, solid-state nuclear magnetic resonance spectroscopy. By contrast to the solution phase, studies on the synthesis of, and catalysis using, organometallic complexes in the solid phase have attracted significantly less attention, even though there are potential benefits to this approach, such as: improved selectivities in synthesis ...

The three organometallic complexes [(Cis-Pt^II (DDH) (2,5- Dihidroxibenzensulfonic)^2, Rh^I (CO)2 Cl(2- Aminobenzothiazole) and Rh^I (CO)2 Cl(5-Cl-2- Methilbenzothiazole)] used in this study had been previously found to have a high in vitro activity against promastigote and amastigote like forms of Leishmania donovani. Here, the cytotoxic effect of these new organometallic complexes on the J-774 macrophages were studied. Only the Rh^I(CO)2 Cl (2-Aminobenzothiazole) complex induced substantial toxicity in the cells.. Also, we assayed the effect of this complex on the parasite s biosynthesis of macromolecules. The Rh^I(CO)2Cl (5-Cl-2- Methylbenzothiazole) complex inhibited DNA, RNA, and protein synthesis. On the other hand, the two other compounds tested did not inhibit the incorporation of radioactive precursors. Finally important ultrastructural alterations in the parasites treated with the two non-cytotoxic complexes were observed ...

Nickelocene - WikipediaNickelocene - Wikipedia
Nickelocene is the organonickel compound with the formula Ni(η5-C5H5)2. Also known as bis(cyclopentadienyl)nickel or NiCp2, this bright green paramagnetic solid is of enduring academic interest, although it does not yet have any known practical applications. Ni(C5H5)2 belongs to a group of organometallic compounds called metallocenes. Metallocenes usually adopt structures in which a metal ion is sandwiched between two parallel cyclopentadienyl (Cp) rings. In the solid-state, the molecule has D5h symmetry, wherein the two rings are eclipsed. The Ni center has a formal +2 charge, and the Cp rings are usually assigned as cyclopentadienyl anions (Cp−), related to cyclopentadiene by deprotonation. The structure is similar to ferrocene. In terms of its electronic structure, three pairs of d electrons on nickel are allocated to the three d orbitals involved in Ni-Cp bonding: dxy, dx2-y2, dz2. One of the two remaining d-electrons resides in each of the dyz and dxz orbitals, giving rise to the ...

The chelates were introduced and assembled through reductive amination starting from 3-O-1,2;5,6-di-O-isopropylidene-alpha-D-glucofuranose]-acetaldehyde. After deprotection, the pyranose derivatives were reacted with the precursor NEt4](2)ReBr3(CO)(3)] to afford the corresponding organometallic complexes in yields between 54% and 94%. The NMR, MS, and IR analyses corroborated the tridentate coordination of the organometallic metal center exclusively via the synthetic chelates. In the case of the N-(acetyl)picolylamine derivative, the coordinative properties were further confirmed by X-ray structure analysis of the first Re(CO)(3)-D-glucofuranose complex.

British Library EThOS: Carbon rich organometallics : from mixed valency to redox active ligandsBritish Library EThOS: Carbon rich organometallics : from mixed valency to redox active ligands
This thesis sets out to explore the electronic structures and redox properties of organometallic complexes. The mixed valence states of these complexes have been investigated and classified. Chapter 1 introduces the general area and provides a brief summary of the theory to electron transfer. The concepts discussed in Chapter 1 are developed further in subsequent Chapters. A trimetallic molecular assembly featuring two redox-active organoiron fragments connected via a central ruthenium tetramesitylporphyrin socket through pendant pyridyl moieties was investigated using electrochemical and UV-vis-NIR/IR spectroelectrochemical studies. Electrochemical studies reveal three reversible oxidation waves, the first two of which can be attributed to the stepwise oxidation of the iron centres. The redox separation between these iron redox waves was found to be constant regardless of electrolyte composition, suggesting a through bond mechanism for electronic interactions between the iron centres. An ...

The use of transition organometallic complexes as reagents for the synthesis of complex organic molecules has been under intensive growth and development for several decades, and many organic transformations of profound synthetic potential has been achieved. Particularly, the use of organoiron complexes has been recognized as a powerful tool in the synthetic methodology due to their ability to react with nucleophiles and electrophiles in a stereoselective fashion. The use of NMO as a chemoselective, metal mediated oxidizing agent will be discussed.

Static solid-state 35Cl (I = 3/2) NMR spectra of the organometallic compounds Cp2TiCl2, CpTiCl3, Cp2ZrCl2, Cp2HfCl2, Cp*2ZrCl2, CpZrCl3, Cp*ZrCl3, Cp2ZrMeCl, (Cp2ZrCl)2μ-O, and Cp2ZrHCl (Schwartzs reagent) have been acquired at 9.4 T with the quadrupolar Carr−Purcell Meiboom−Gill (QCPMG) sequence in a piecewise manner. Spectra of several samples have also been acquired at 21.1 T. The electric field gradient (EFG) tensor parameters, the quadrupolar coupling constant (CQ) and quadrupolar asymmetry parameter (ηQ), are readily extracted from analytical simulations of the spectra. The 35Cl EFG and chemical-shift tensor parameters are demonstrated to be sensitive probes of metallocene structure and allow for differentiation of monomeric and oligomeric structures. First-principles calculations of the 35Cl EFG parameters successfully reproduce the experimental values and trends. The origin of the observed values of CQ(35Cl) are further examined with natural localized molecular orbital (NLMO) ...

N2 - Rationale: Treatment with a carbon monoxide-releasing molecule (tricarbonyldichlororuthenium(II) dimer, CORM-2) or a classical heme oxygenase 1 inducer (cobalt protoporphyrin IX, CoPP) has potent anti-inflammatory effects, but the role played by these treatments in the antinociceptive effects of morphine during acute and chronic pain was not evaluated. Objectives: In wild type (WT), neuronal (NOS1-KO), or inducible (NOS2-KO) nitric oxide synthases knockout mice, we evaluated the effects of CORM-2 and CoPP treatments in the antinociceptive actions of morphine and their interaction with nitric oxide during acute, visceral, and chronic inflammatory or neuropathic pain.

The protective roles of some lichen species on colloidal bismuth subcitrate genotoxicity | AVESİSThe protective roles of some lichen species on colloidal bismuth subcitrate genotoxicity | AVESİS
Medicinal plants are increasingly being projected as suitable alternative source for the treatment of various diseases. However, toxic effects resulting from therapeutic bismuth compounds are still documented in animals and humans. This study described the genetic effects of five common lichen species and compared their activities on the genotoxicity induced by the colloidal bismuth subcitrate. After the application of colloidal bismuth subcitrate and lichen extracts, separate and together, human whole blood cultures were assessed by sister-chromatid exchange (SCE) and micronucleus tests. According to our results, the frequencies of SCE and micronucleus rate in peripheral lymphocytes were significantly increased by colloidal bismuth subcitrate (at dose 5 mu g/mL) compared with controls. However, lichen extracts had no genotoxic effect. The order of anti-genotoxicity efficacy against colloidal bismuth subcitrate was Pseudevernia furfuracea, Dermotocarpon intestiniforme, Ramalina capitata, ...

Reaction of Organic Halogen Compounds with Metals (Part Ⅰ) A Formation of Organometallic Complex in Dimethyl Formamide Solvent Reaction of organic chlorine containing ester, alcohol, and acids with metallic tin and zinc in dimethyl formamide solvent gave a good yield of organo metallic complex. The same reaction under a mixed U.V. irradiation could not give an appreciable yield of the complex except in the case of an elevated reaction temperature. The solvation effect of dimethyl formamide of the metallic complex formation was markedetly increased as compared to the reaction in toluene and cyclohexane. In case of chlorine containing carboxylic acid, the formation of organo chloro zinc complex of the salt was observed. The reaction of organo zinc complex with a carbonyl precursor gave the addition product together with a dimerized product. Especially the aldehyde species enhanced the formation of zinc complex. The addition reaction was simple and convenient, but the yield was not high.(30-40% for

CO and 4 of the CORMs (ALF 153, 157, 436 and CORM-2) increased cGMP levels in smooth muscle cells, while the rest of the compounds failed to alter cGMP production. The CORM-stimulated increase was minor (50-300% over basal) compared to the effects seen with the NO-donor, SNP (at least 100-fold). CORM-3, a widely used CORM, decreased basal cGMP levels in RASMC. Interestingly, CO and CORMs modestly reduced SNP-stimulated cGMP formation in RASMC. The inactive forms of CORMs (compounds lacking the ability to liberate CO) did not affect SNP-induced cGMP accumulation. CORMs also reduced bradykinin-stimulated cGMP levels in endothelial-smooth muscle co-cultures. In sGC activity assays using purified recombinant human sGC, CORMs were ineffective in stimulating cGMP production. However, CORMs blocked up to 80% of DEA-NO-induced sGC activity. ...

Photophysical evaluation of substituted zinc phthalocyanines as sensitisers for photodynamic therapy - Durham e-ThesesPhotophysical evaluation of substituted zinc phthalocyanines as sensitisers for photodynamic therapy - Durham e-Theses
Zinc phthalocyanines (ZnPc) are currently being investigated in relation to their use as sensitisers for Photodynamic Therapy (PDT). In particular, the photophysical properties of these dyes are of interest since then- ability to generate the cytotoxic species, singlet oxygen ((^1)O(_2)), is believed to be central to their role in causing tumour necrosis. In this study, a detailed investigation of the photophysical properties of substituted zinc phthalocyanines under various conditions is described. Two novel β-tetra substituted zinc phthalocyanines have been synthesised, ZnPc(CMe(C0(_2)Me)(_2))(_4) and ZnPc(CHMeCO(_2)H)(_4). The nature of peripheral substituents has little effect on triplet state or singlet oxygen production by ZnPc, however, ZnPc(CHMeCO(_2)H)(_4) displays a remarkable sensitivity to the ionic strength of non aqueous solutions. Ion concentrations below 10(^-4) mol dm(^-3) induce dimerisation whilst concentrations greater than this promote monomerisation. This behaviour is ...

Brevet US5387568 - Preparation of metallocene catalysts for polymerization of olefins - Google BrevetsBrevet US5387568 - Preparation of metallocene catalysts for polymerization of olefins - Google Brevets
This invention uses a new method of producing ionic metallocene compounds. These compounds are useful as catalysts for polymerization of olefins, primarily propylene. This method uses an ionizing agent which ionizes the neutral metallocene compound. The ionizing ionic compound does not contain an active proton and contains a carbonium, oxonium or sulfonium cation. The anion of the ionizing ionic compound is not coordinated or is only loosely coordinated to the metallocene cation and is chemically unreactive with the metallocene cation. Examples of such compounds are triphenylcarbenium tetrakis(pentafluorophenyl)boronate, triphenylcarbenium tris(pentafluorophenyl)phenyl boronate and triphenylcarbeniumtris(pentafluorophenyl)4-trimethylsilyl-2,3,5,6-tetrafluorophenylboronate. The process of making catalysts with this invention produces catalysts having high activity and does not produce by-products which can inhibit catalyst activity. This new synthesis is a clean reaction which does not produce a Lewis

Carbohydrate - metallocene conjugates. Metallocenes are organometallic compounds characterized by a transition metal central atom (M) bound to cyclopentadienide (Cp-/C5H5-) ligands, the general formula of metallocenes being Cp2M. Titanocene dichloride was among the first non-platinum organometallics investigated as promising anticancer agents. Although its clinical trials were stopped because of low efficacy and other drawbacks, the last two decades have witnessed renewed research interest in anticancer metallocenes. We have started a programme aimed at improving cytotoxic activity and pharmacological properties of metallocenes by their conjugation to carbohydrates, iminosugars and selected heterocycles. Carbohydrates and iminosugars have typicaly 3 - 6 functional groups that can be modified to ameliorate cytotoxic profile, bioavailability, solubility, biocompatibility, and hydrophobic/hydrophilic balance of the resulting metallocene-carbohydrate conjugate. Recently, we have extended this ...

We report the synthesis and analysis of metallocenes (ferrocene, chromocene, ruthenocene, vanadocene, tungstenocene-dihydride) encapsulated in single wall carbon nanotubes (SWNTs). In the case of ferrocene, efficient filling of the SWNTs was accomplished from both the liquid and the vapor phase. The other two metallocenes were filled from the vapor phase. High resolution transmission electron microscopy reveals single molecular chains of metallocenes inside SWNTs. Molecules move under the electron beam in the SWNTs indicating the absence of strong chemical bonds between each other and the SWNT wall. Their movement freezes after short illumination as a result of irradiation damage. Energy dispersive X-ray spectrometry confirms the presence of iron, chromium, ruthenium, vanadium and tungsten.

Hierarchical self-assembly of a chiral metal-organic framework displaying pronounced porosity - ResearchOnline@JCUHierarchical self-assembly of a chiral metal-organic framework displaying pronounced porosity - [email protected]
Extract] Significant recent attention has been devoted to the development of useful self-assembled hybrid materials.[1] This is particularly the case for metal-organic frameworks (MOFs), which display properties such as regularity, porosity, robustness, and high surface area that lead to potential applications in areas such as catalysis, gas separation, and storage.[2, 3] Our research groups and others have been developing new methods for the synthesis of both discrete and extended metal-organic materials, with particular interest in the controlled generation of increased structural complexity.[4] Herein we report a hierarchical self-assembly strategy which has been used to synthesize a new metal-organic framework. This strategy differs from the commonly employed molecular building block (MBB) and secondary building unit (SBU) approaches, where single metal ions or small inorganic clusters (polyhedra) are linked by bridging (often carboxylate) ligands in a one-pot reaction.[5] In these ...

Cyclopentadienyl complex - WikipediaCyclopentadienyl complex - Wikipedia
All 5 carbon atoms of a Cp ligand are bound to the metal in the vast majority of M-Cp complexes. This bonding mode is called η5-coordination. The M-Cp bonding arises from overlap of the five π molecular orbitals of the Cp ligand with the s, p, and d orbitals on the metal. This π bonding is significant, hence these complexes are referred to as π-complexes. Almost all of the transition metals, that is, group 4 to 10 metals, employ this coordination mode.[1]. In relatively rare cases, Cp binds to metals via only one carbon center. These types of interactions are described as σ-complexes because they only have a σ bond between the metal and the cyclopentadienyl group. Typical examples of this type of complex are group 14 metal complexes such as CpSiMe3. An example of both is (Cp2Fe(CO)2).. It is probable that η1-Cp complexes are intermediates in the formation of η5-Cp complexes. Still rarer, the Cp unit can bond to the metal via a three-carbons. In these η3-Cp complexes, the bonding ...

These results indicate that pretreatment of rats with the synthetic catalytic scavenger of ROS, EUK-134, prevents oxidative stress and produces a significant degree of protection against the pathological manifestations of KA-induced seizure activity in hippocampus and piriform cortex. Although numerous studies have suggested that ROS are critically involved in excitotoxicity (see refs. 5, 30, and 31 for reviews), very few studies have demonstrated convincingly, in an in vivo excitotoxic model, a causal relationship between increased production of ROS and neuronal damage (7, 32). A clear demonstration of the crucial role of ROS in excitotoxicity should include: (i) evidence for increased production of ROS specifically in neuronal populations at risk with excitotoxicity before overt signs of neuronal damage and (ii) evidence that manipulations aimed at preventing ROS accumulation reduce neuronal damage without interfering with excitatory amino acid receptor functions. The former has been difficult ...

Cobaltocene - WikipediaCobaltocene - Wikipedia
In Co(C5H5)2 the Co centre is sandwiched between two cyclopentadienyl (Cp) rings. The Co-C bond lengths are about 2.1 Å, slightly longer than the Fe-C bond in ferrocene.[3]. Co(C5H5)2 belongs to a group of organometallic compounds called metallocenes or sandwich compounds.[4] Cobaltocene has 19 valence electrons, one more than usually found in organotransition metal complexes such as its very stable relative ferrocene. (See 18-electron rule.) This additional electron occupies an orbital that is antibonding with respect to the Co-C bonds. Consequently, the Co-C distances are slightly longer than the Fe-C bonds in ferrocene. Many chemical reactions of Co(C5H5)2 are characterized by its tendency to lose this extra electron, yielding an 18-electron cation known as cobaltocenium: ...

Over the past several years we have devised and expanded the capabilities of Zeeman atomic absorption spectroscopy (ZAA). Using this technique, trace elements in a complex matrix can be directly analyzed with high accuracy even when there is only one atom of interest contained in several million atoms of the host material. Quantities in the nanogram, or in some cases picogram, range can be determined within IS seconds for more than 30 elements. Because of its high selectivity and high sensitivity, ZAA can be used as a new technique for organometallic species determination by interfacing with a high pressure liquid chromatograph (HPLC). The HPLC separates various molecular species. Different kinds of mobil solvents can be directly introduced in the ZAA detection system; even organic solvents or high concentration salt solutions. Then, organometallic species in the ppb range are separately detected according to their retention times. This technique has a much larger field of application than HPLC coupled

Unusual Structures and Physical Properties in Organometallic Chemistry | Coordination Chemistry | Inorganic Chemistry |...Unusual Structures and Physical Properties in Organometallic Chemistry | Coordination Chemistry | Inorganic Chemistry |...
The principal idea of this volume is to offer a Capita Selecta of unconventional and thought-provoking topics in organometallic chemistry, presented by experts in each field. As intended, this approach leads either to reviews covering a specific uncommon class of organometallic compounds or to overviews which relate uncommon physical properties with various classes of organometallic compounds. The contributions are streamlined thus onto two main axes - unusual properties reflecting structures and bonding situations, on the one hand, and uncommon structural features or structure-reactivity relationships, on the other. Extensive cross-referencing of useful information is provided, making this volume accessible for people working in rather different areas of organometallic chemistry ...

In this prospective referring-physician-based survey, we investigated the definite clinical impact of 68Ga-DOTATATE PET/CT on managing patients with neuroendocrine tumors (NETs). Methods: We prospectively studied 130 patients with 68Ga-DOTATATE PET/CT referred for initial or subsequent management decisions (NCT02174679). Referring physicians completed one questionnaire before the scan (Q1) to indicate the treatment plan without PET/CT information, one immediately after review of the imaging report to denote intended management changes (Q2), and one 6 mo later (Q3) to verify whether intended changes were in fact implemented. To further validate the Q3 responses, a systematic electronic chart review was conducted. Results: All 3 questionnaires were completed by referring physicians for 96 of 130 patients (74%). 68Ga-DOTATATE PET/CT resulted in intended management changes (Q2) in 48 of 96 patients (50%). These changes were finally implemented (Q3) in 36 of 48 patients (75%). Q3 responses were ...
