Microbial desulfurization of organic sulfur compounds in petroleum. (1/1894)

Sulfur removal from petroleum is important from the standpoint of the global environment because the combustion of sulfur compounds leads to the production of sulfur oxides, which are the source of acid rain. As the regulations for sulfur in fuels become more stringent, the existing chemical desulfurizations are coming inadequate for the "deeper desulfurization" to produce lower-sulfur fuels without new and innovative processes. Biodesulfurization is rising as one of the candidates. Several microorganisms were found to desulfurize dibenzothiophene (DBT), a representative of the organic sulfur compounds in petroleum, forming a sulfur-free compound, 2-hydroxybiphenyl. They are promising as biocatalysts in the microbial desulfurization of petroleum because without assimilation of the carbon content, they remove only sulfur from the heterocyclic compounds which is refractory to conventional chemical desulfurization. Both enzymological and molecular genetic studies are now in progress for the purpose of obtaining improved desulfurization activity of organisms. The genes involved in the sulfur-specific DBT desulfurization were identified and the corresponding enzymes have been investigated. From the practical point of view, it has been proved that the microbial desulfurization proceeds in the presence of high concentrations of hydrocarbons, and more complicated DBT analogs are also desulfurized by the microorganisms. This review outlines the progress in the studies of the microbial desulfurization from the basic and practical point of view.  (+info)

5-HT2B-receptor antagonist LY-272015 is antihypertensive in DOCA-salt-hypertensive rats. (2/1894)

We previously demonstrated a change in the receptors mediating 5-hydroxytryptamine (5-HT)-induced contraction in arteries of deoxycorticosterone acetate (DOCA)-salt-hypertensive rats. Specifically, contraction to 5-HT is mediated primarily by 5-HT2A receptors in arteries from normotensive sham rats and by both 5-HT2A and 5-HT2B receptors in arteries from hypertensive rats. We hypothesized that the 5-HT2B receptor may play a role in maintaining the high blood pressure of DOCA-salt-hypertensive rats, and herein we provide data connecting in vitro and in vivo findings. The endothelium-denuded isolated superior mesenteric artery of DOCA-salt rats displayed a marked increase in maximum contraction to the newly available 5-HT2B-receptor agonist BW-723C86 compared with that of arteries from sham rats, confirming that the 5-HT2B receptor plays a greater role in 5-HT-induced contraction in arteries from DOCA-salt rats. In chronically instrumented rats, the 5-HT2B-receptor antagonist LY-272015 (0.3, 1.0, and 3.0 mg/kg iv at 30-min intervals) was given cumulatively 1 time/wk during 4 wk of continued DOCA-salt treatment. LY-272015 did not reduce blood pressure of the sham-treated rats at any time or dose. However, LY-272015 (1.0 and 3. 0 mg/kg) significantly reduced mean blood pressure in a subgroup of week 3 (-20 mmHg) and week 4 DOCA-salt (-40 mmHg) rats that had extremely high blood pressure (mean arterial blood pressure approximately 200 mmHg). Blockade of 5-HT2B receptors by in vivo administration of LY-272015 (3.0 mg/kg) was verified by observing reduced 5-HT-induced contraction in rat stomach fundus, the tissue from which the 5-HT2B receptor was originally cloned. These data support the novel hypothesis that 5-HT2B-receptor expression is induced during the development of DOCA-salt hypertension and contributes to the maintenance of severe blood pressure elevations.  (+info)

Cleavage of the HER2 ectodomain is a pervanadate-activable process that is inhibited by the tissue inhibitor of metalloproteases-1 in breast cancer cells. (3/1894)

HER2/neu, a Mr 185,000 tyrosine kinase receptor that is overexpressed in breast cancer, undergoes proteolytic cleavage of its extracellular domain (ECD). In contrast with other membrane-bound proteins, including growth factor receptors, that are cleaved by a common machinery system, we show that HER2 cleavage is a slow process and is not activated by protein kinase C. Pervanadate, a general inhibitor of protein-tyrosine phosphatases, induces a rapid and potent shedding of HER2 ECD. The shedding of HER2 ECD is inhibited by the broad-spectrum metalloprotease inhibitors EDTA, TAPI-2, and batimastat. The tissue inhibitor of metalloproteases-1; an inhibitor of matrix metalloproteases that does not inhibit cleavage by the general protein kinase C-dependent shedding machinery, also inhibited HER2 ECD shedding, whereas tissue inhibitor of metalloproteases-2 did not. These data suggest that HER2 cleavage is a process regulated by an as-yet-unidentified distinct protease.  (+info)

Phase I study of intrapleural batimastat (BB-94), a matrix metalloproteinase inhibitor, in the treatment of malignant pleural effusions. (4/1894)

Tumor cells and associated stromal cells secrete matrix metalloproteinases (MMPs), contributing to invasion, angiogenesis, and metastasis. Batimastat (BB-94) is a broad-spectrum MMP inhibitor that causes resolution of ascites and/or tumor growth delay in animal models of breast, ovarian, and colorectal cancer. We recruited 18 patients with cytologically positive malignant pleural effusions into a Phase I study of intrapleural BB-94. Three patients received single doses of BB-94 at each dose level: 15, 30, 60, 105, 135, and 300 mg/m2. Two patients were retreated with a second course at 60 and 105 mg/m2. BB-94 was detectable in plasma 1 h after intrapleural administration, and peak levels of 20-200 ng/ml occurred after 4 h to 1 week. BB-94 persisted in the plasma for up to 12 weeks, at levels exceeding the IC50s for target MMPs. Peak values were higher, and persistence in the plasma was longer after higher doses of BB-94. The treatment was well tolerated. Toxic effects included low-grade fever for 24-48 h (6 of 18 patients, 33%) and reversible asymptomatic elevation of liver enzymes (8 patients, 44%). Toxicity seemed unrelated to BB-94 dose or plasma levels. Sixteen patients evaluable for response required significantly fewer pleural aspirations in the 3 months after BB-94 compared with the 3 months before. Seven patients (44%) required no further pleural aspiration until death/last follow-up. After 1 month, patients treated with 60-300 mg/m2 BB-94 had significantly better dyspnea scores, indicating improved exercise tolerance, compared with baseline scores the day after BB-94. The maximum tolerated intrapleural dose remains to be defined, but it is clear that intrapleural BB-94 is well tolerated, with evidence of local activity.  (+info)

Limited anti-inflammatory efficacy of cyclo-oxygenase-2 inhibition in carrageenan-airpouch inflammation. (5/1894)

1. Cyclo-oxygenase-2 (COX-2) is expressed at sites of inflammation and is believed to be the major source of inflammation-associated prostaglandin synthesis. Selective inhibition of COX-2 has been suggested to produce anti-inflammatory effects with reduced toxicity in the gastrointestinal tract. We examined the extent to which suppression of COX-2 led to inhibition of various components of inflammation in the carrageenan-airpouch model in the rat. 2. Indomethacin (> or =0.3 mg kg(-1)), nimesulide (> or =3 mg kg(-1)) and the selective COX-2 inhibitor, SC-58125 (> or =0.3 mg kg(-1)), significantly suppressed the production of prostaglandin E2 at the site of inflammation. At higher doses, indomethacin (> or =1 mg kg(-1)) and nimesulide (30 mg kg(-1)), but not SC-58125 (up to 10 mg kg(-1)), significantly inhibited COX-1 activity (as measured by whole blood thromboxane synthesis). 3. All three test drugs significantly reduced the volume of exudate in the airpouch, but only at doses greater than those required for substantial (>90%) suppression of COX-2 activity. Similarly, reduction of leukocyte infiltration was only observed with the doses of indomethacin and nimesulide that caused significant suppression of COX-1 activity. 4. SC-58125 did not significantly affect leukocyte infiltration into the airpouch at any dose tested (up to 10 mg kg(-1)). A second selective COX-2 inhibitor, Dup-697, was also found to suppress exudate PGE2 levels without significant effects on leukocyte infiltration. 5. These results indicate that selective inhibition of COX-2 results in profound suppression of PGE2 synthesis in the carrageenan-airpouch, but does not affect leukocyte infiltration. Exudate volume was only reduced with the highly selective COX-2 inhibitor when a dose far above that necessary for suppression of COX-2 activity was used. Inhibition of leukocyte infiltration was observed with indomethacin and nimesulide, but only at doses that inhibited both COX-1 and COX-2.  (+info)

Effects of angiogenesis inhibitors on multistage carcinogenesis in mice. (6/1894)

Solid tumors depend on angiogenesis for their growth. In a transgenic mouse model of pancreatic islet cell carcinogenesis (RIP1-Tag2), an angiogenic switch occurs in premalignant lesions, and angiogenesis persists during progression to expansive solid tumors and invasive carcinomas. RIP1-Tag2 mice were treated so as to compare the effects of four angiogenesis inhibitors at three distinct stages of disease progression. AGM-1470, angiostatin, BB-94, and endostatin each produced distinct efficacy profiles in trials aimed at preventing the angiogenic switch in premalignant lesions, intervening in the rapid expansion of small tumors, or inducing the regression of large end-stage cancers. Thus, anti-angiogenic drugs may prove most efficacious when they are targeted to specific stages of cancer.  (+info)

Marked suppression of T cells by a benzothiophene derivative in patients with human T-lymphotropic virus type I-associated myelopathy/tropical spastic paraparesis. (7/1894)

In a search for new anti-autoimmune agents that selectively suppress activation of autoreactive T cells, one such agent, 5-methyl-3-(1-methylethoxy)benzo[b]thiophene-2-carboxamide (CI-959-A), was found to be effective. This compound, which is known to suppress tumor necrosis factor alpha (TNF-alpha)-induced CD54 expression, inhibited the primary proliferative response of the T cell to antigen (Ag)-presenting cells (APCs) including allogenic dendritic cells (DCs), autologous Epstein-Barr virus-infected B cells, and human T lymphotropic virus type I (HTLV-I)-infected T cells. Autoreactive T cells from patients with HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) spontaneously proliferate in vitro, and their activation is reported to be associated with CD54 expression. The spontaneous proliferation of T cells from patients with HAM/TSP was entirely blocked by CI-959-A. However, in this study, the T-cell proliferation in 15 patients with HAM/TSP was found to depend more extensively on major histocompatibility complex (MHC) class II and CD86 than on CD54 Ags. Since most important APCs for the development of HAM/TSP are DCs and HTLV-I-infected T cells, the effect of CI-959-A on DC generation and on the expression of surface molecules on activated T cells is examined. CI-959-A suppressed recombinant granulocyte-macrophage colony stimulating factor (GM-CSF)- and recombinant interleukin-4-dependent differentiation of DCs from monocytes and inhibited the expression of CD54 and, more extensively, MHC class II and CD86 Ags. CI-959-A showed little toxicity toward lymphoma or HTLV-I-infected T-cell lines or toward monocytes and cultured DCs. These results suggest that CI-959-A might be a potent anti-HAM/TSP agent.  (+info)

Dorzolamide effect on ocular blood flow. (8/1894)

PURPOSE: To evaluate the effect of dorzolamide on ocular blood flow in normal and glaucomatous eyes. METHODS: Twenty-six eyes with documented open-angle glaucoma of 26 patients and 13 normal control eyes of 8 age-matched subjects were included in this study. All eyes underwent color Doppler imaging for measuring peak-systolic velocity, end-diastolic velocity, and resistance index in the ophthalmic and central retinal arteries and the maximal and minimal velocities in the central retinal vein. Eyes were grouped in control and initial and advanced glaucoma categories. Measurements were made in all groups before and after application of topical dorzolamide. Intragroup comparisons between baseline and dorzolamide conditions were made using paired Student's t-test. Intergroup comparisons under baseline conditions between normal and glaucomatous eyes were made by using the one-way ANOVA test. Statistical significance was set at P < 0.05. RESULTS: The peak-systolic velocity of the central retinal artery in glaucomatous eyes and the end-diastolic velocity of the ophthalmic and central retinal arteries in all groups were significantly higher after application of dorzolamide. The minimal velocity of the central retinal vein showed significantly higher values after dorzolamide, whereas the maximal velocity remained unchanged. The peak-systolic velocity of the ophthalmic artery in all groups and the peak-systolic velocity of the central retinal artery in normal eyes also remained unchanged. The resistance index was significantly lower in the ophthalmic and central retinal arteries in all groups after dorzolamide. The intraocular pressure was significantly reduced in all groups after dorzolamide. Under baseline conditions normal control eyes and glaucomatous eyes showed differences in various measurements. Peak-systolic velocity was significantly lower in glaucomatous eyes than in normal control eyes with the exception of the ophthalmic artery in the initial glaucoma group. End-diastolic velocity was lower in glaucomatous eyes than in control eyes in both arteries. Maximal and minimal velocities of the central retinal vein were lower in glaucomatous eyes than in normal control eyes. Resistance index was higher in glaucomatous eyes than in normal control eyes in the ophthalmic artery but not in the central retinal artery. CONCLUSIONS: Most hemodynamic parameters of intraocular and periocular vessels improve after application of topical dorzolamide in both normal control and glaucomatous eyes. Dorzolamide should be regarded as a useful drug for treatment of glaucoma not only because it reduces intraocular pressure but also because it improves the ocular blood supply.  (+info)

Show more ,Combretastatin A-4 and isocombretastatin A-4 derivatives having thiophenes or benzo[b]thiophenes instead of the B ring were prepared and evaluated for their in cellulo tubulin polymerization inhibition (TPI) and antiproliferative activities. The presence of the benzo[b]thiophene ring proved to have a crucial effect as most of the thiophene derivatives, except those having one methoxy group, were inactive to inhibit tubulin polymerization into microtubules. The influence of the attachment position was also studied: benzo[b]thiophenes having iso or cis 3,4,5-trimethoxystyrenes at position 2 were 12-30-fold more active than the 3-regioisomers for the TPI activity.

Thiophene is a maillard product At room temperature, thiophene is a colorless liquid with a mildly pleasant odor reminiscent of benzene, with which thiophene shares some similarities. The high reactivity of thiophene toward sulfonation is the basis for the separation of thiophene from benzene, which are difficult to separate by distillation due to their similar boiling points (4 C difference at ambient pressure). Like benzene, thiophene forms an azeotrope with water. Not only is thiophene reactive toward electrophiles, it is also readily lithiated with butyl lithium to give 2-lithiothiophene, which is a precursor to a variety of derivatives, including ...

Leishmania major (L. major) is a protozoan parasite that causes cutaneous leishmaniasis. About 12 million people are currently infected with an annual incidence of 1.3 million cases. The purpose of this study was to synthesize a small library of novel thiophene derivatives, and evaluate its parasitic activity, and potential mechanism of action (MOA). We developed a structure-activity relationship (SAR) study of the thiophene molecule 5A. Overall, eight thiophene derivatives of 5A were synthesized and purified by silica gel column chromatography. Of these eight analogs, the molecule 5D showed the highest in vitro activity against Leishmania major promastigotes (EC50 0.09 ± 0.02 µM), with an inhibition of the proliferation of intracellular amastigotes higher than 75% at only 0.63 µM and an excellent selective index. Moreover, the effect of 5D on L. major promastigotes was associated with generation of reactive oxygen species (ROS), and in silico docking studies suggested that 5D may play a role in

The preparation of a new poly(thiophene) with pendant N-hydroxysuccinimide ester groups and its application to immobilization of biomolecules are reported. A thiophene derivative of N-hydroxysuccinimide ester was polymerized with FeCl3 in chloroform and the resulting poly(thiophene) was characterized by nuclear magnetic resonance (NMR), Fourier transform infrared (FT-IR), and gel permeation chromatography (GPC). This polymer reacts with amine-bearing molecules to yield new poly(thiophene) derivatives and the specific interactions at the side groups could be detected. Thus, a self-assembled monolayer (SAM) using the polymer was formed on a gold-coated quartz cell and anti-C-reactive protein (anti-CRP) was immobilized. The binding behavior of CRP on the surface was monitored by use of a surface plasmon resonance (SPR) sensor system. © 2008 Elsevier B.V. All rights reserved. ...

According to the available literature, up to present date, only one sulfilimine derivative of benzo[b]thiophene is reported and several sulfilimine and sulfoximine derivatives of monocyclic thiophene. Guided by this fact, we have prepared the reported sulfilimine and new sulfoximine derivative of benzo[b]thiophene that was previously unknown. The known synthesis of sulfilimine N- [1λ4-benzo[b]thiophenylidene]-4-methylbenzenesulfonamide (15) was followed in order to oxidise it and to obtain its sulfoximine. After few attempted oxidations, as well as preparations of other analogues of the aforementioned sulfilimine, we have successfully prepared sulfoximine 4-methyl-N- [1-oxo-1H-1λ6benzo[b]thiophen-1-ylidene]benzenesulfonamide by oxidation with H2O2-P2O5 reagent.

Prothrombin time (PT) is a global clotting test assessing the extrinsic pathway of the blood coagulation cascade. The test is sensitive for deficiencies of Factors II, V, VII, and X, with sensitivity being best for Factors V, VII, and X and less pronounced for Factor II. The initial read-out of PT is in seconds. The PT slope describes the linear increase of PT for one unit increase in concentration, thus the unit of PT slope is s*(µg/L)^-1. The final population PK/PD model included a fixed slope that was fitted to the data of the 19 patients that were eligible for evaluation. The estimated mean value (fixed/ the same for all patients in this study) is presented for PT slope ...

TY - JOUR. T1 - d-orbital participation in bonding in thiophene. T2 - Comparison of CNDO/2 and ab initio results. AU - Náray-Szabó, G.. AU - Peterson, M. R.. PY - 1981/11. Y1 - 1981/11. N2 - We have compared CNDO/2 and ab initio STO-3G calculations for furan and thiophene with and without the inclusion of 3d-orbitals on oxygen and on sulphur. Comparison of localized molecular orbitals indicates that d-orbital participation is over-estimated within the CNDO/2 approximation, although trends are reflected correctly. Enhanced aromaticity of thiophene compared to furan is primarily due to the delocalization of C2C3 π-bonds to the vacant d-orbitals of sulphur. On the other hand, d-orbitals are unimportant in describing σ-bonds. Energies of canonical molecular orbitals, as obtained with the CNDO/2 and ab initio STO-3G* methods and divided into separate σ and π groups, run parallel with each other within both groups.. AB - We have compared CNDO/2 and ab initio STO-3G calculations for furan and ...

Synthesis and characterization of thiophene functionalized polystyrene copolymers and their electrochemical propertiesSynthesis and characterization of thiophene functionalized polystyrene copolymers and their electrochemical properties
Thiophene functionalized polystyrene samples (TFPS) were synthesized by atom transfer radical polymerization (ATRP) of styrene, followed by Suzuki coupling with 3-thiophene (Th) boronic acid. Conducting graft polymer of TFPS with thiophene was achieved at 1.5 V in tetrabutylammonium tetrafluoroborate/dichloromethane (TBAFB/DM) by electrochemical methods. Spectroelectrochemical analysis of the resulting copolymers [P(TFPS-co-Th)] reflected electronic transitions at 449, 721 and 880 nm, revealing pi - pi* transition, polaron and bipolaron band formation, respectively. We also successfully established the utilization of dual type complementary colored polymer electrochromic devices using P(TFPS-co-Th)/poly(3,4-ethylenedioxythiophene (PEDOT) in sandwich configuration. The switching ability, stability and optical memory of the electrochromic device were investigated by UV-visible spectrophotometry and cyclic voltammetry. Device switches between brown and blue color with a switching time of 1.3 s were ...

Peripheral Artery Disease, the Factor Xa Inhibitor Rivaroxaban, and the Role of the Podiatrist | Journal of CLIPeripheral Artery Disease, the Factor Xa Inhibitor Rivaroxaban, and the Role of the Podiatrist | Journal of CLI
As podiatrists, we are aware of the complications of PAD, with over 8.5 million people within the United States afflicted by this disease.32 With a significant number of these individuals being asymptomatic, awareness of this disease is paramount to all lower-extremity physicians. PAD is often diagnosed only when it reaches a symptomatic or critical stage, at which point treatment tends to focus on endovascular or surgical procedures.33 While these techniques have evolved and innovative treatments continue to be developed, these options do not address the underlying pathophysiologic development of PAD. Atherosclerotic disease includes PAD, CAD, and cerebrovascular disease (CVD). These disease states have significant overlap, as evidenced in the REACH registry where 3 out of 5 patients with PAD also had CAD and/or CVD. REACH was a large, global, observational registry of ~68,000 patients in 44 countries who were at high risk of atherothrombosis.34 Nearly 1 in 5 patients from the REACH registry ...

The composition of non-methane organic volatile compounds (VOCs) determined in 139 thermal gas discharges from 18 different geothermal and volcanic systems in Italy and Latin America, consists of C2-C20 species pertaining to the alkanes, alkenes, aromatics and O-, S- and N-bearing classes of compounds. Thiophenes and mono-aromatics, especially the methylated species, are strongly enriched in fluids emissions related to hydrothermal systems. Addition of hydrogen sulphide to dienes and electrophilic methylation involving halogenated radicals may be invoked for the formation of these species. On the contrary, the formation of furans, with the only exception of C4H8O, seems to be favoured at oxidizing conditions and relatively high temperatures, although mechanisms similar to those hypothesized for the production of thiophenes can be suggested. Such thermodynamic features are typical of fluid reservoirs feeding high-temperature thermal discharges of volcanoes characterised by strong degassing activity,

The deposited films of both BP1T and AC5 showed a microcrystalline phase, and initial microcrystals got larger 10 - 100 times with thermal treatment. Furthermore, we measured the optical properties of microcrystals of BP1T and AC5. At the energy density below the spontaneous amplified emission threshold, it was found that there was a big fluorescent difference between femtosecond laser irradiation and continuous lamp irradiation ...

Synthesis and characterization of a new class of thiophene containing by Javier Santos-PerezSynthesis and characterization of a new class of thiophene containing by Javier Santos-Perez
Photoresponsive molecules have a broad range of potential applications, for example in optical, energy, and biomedical technologies. Fluorophores and second order nonlinear optical (NLO) chromophores are photoresponsive molecules used as signaling materials and frequency doublers or electro-optical modulators, respectively. The research presented here describes the synthesis, characterization, and potential applications of a group of highly fluorescent molecules and NLO chromophores containing benzene, imidazole and thiophene rings. Methyl, methoxy, and dimethylamino groups were used as electron donor groups while formyl and nitro groups were used as electron acceptors. The fluorescence properties of a series of dyes containing donor groups and a formyl group attached to a thiophenyl ring were investigated. X-ray structural determination revealed a steric crowding, which causes a molecular twist in the ground state. The fluorescence quantum yield for these fluorophores was found in the range of0.004-1.0

NSC 652287 is a representative of a novel class of thiophene derivatives discovered in the NCI Anticancer Drug Screen for their activity against the subpanel of cell lines derived from renal cancer, a disease for which present chemotherapy has limited activity. The present study shows that thiophene NSC 652287 is a potent inducer of apoptosis at submicromolar concentrations. Apoptosis was associated with p53 elevation and decrease of p21WAF1 protein levels in A498 cells. By contrast, lower NSC 652287 concentrations induced elevation of both p53 and p21WAF1 and cell cycle arrest (Fig. 3 and Table 2). A decrease of p21WAF1 in spite of p53 elevation at NSC 652287 concentrations that induced apoptosis was probably due to p21WAF1 degradation during apoptosis. p21WAF1 is indeed a substrate for caspases (Gervais et al., 1998).. Although A498 cells have wild-type p53 and are very sensitive to NSC 652287, two of the most resistant kidney cell lines of the NCI Anticancer Drug Screen, ACHN and UO-31, also ...

Acid dissociation constants, pKa, of 2-pyrrolaldehyde phenylsulphonyl hydrazone, 1, and 2-thiophenealdehyde phenylsulphonyl hydrazone, 2, have been determined spectrophotometrically in ethanol-water media of various compositions over the temperature range 25℃ - 45℃. The obtained results were used in the calculation of the enthalpy, △H°, and the entropy, △S°, of the ionization processes. The slight variations observed in the pKa values of the thiophene compound compared to the pyrrol analogue revealed that neither of the two hetero atoms in the pyrrol or thiophene rings, of the two compounds, is involved in a hydrogen bond chelation. This conclusion was also confirmed through measurements of the dipole moment, IR and NMR spectra.

In order to tune the optoelectronic and charge transfer properties of 4,6-di(thiophen-2-yl)pyrimidine (1), some new compounds were designed, i.e., 4,6-bis(benzo[$b$]thiophen-2-yl)pyrimidine (2), 4,6-bis(naphtho[2,3-b]thiophen-2-yl)pyrimidine (3), 4,6-bis(anthra[2,3-b]thiophen-2-yl)pyrimidine (4), 4,6-bis(tetraceno[2,3-$b$]thiophen-2-yl)pyrimidine (5) and 4,6-bis(pentaceno[2,3-$b$]thiophen-2-yl)pyrimidine (6). Compounds 2-6 were designed by assimilation of benzene, naphthalene, anthracene, tetracene and pentacene, respectively at both ends of compound 1. Integration of oligocene end cores reduces the energy gap resulting in a red shift in the absorption and fluorescence emission spectra. The legible intra-molecularcharge transfer is significant from electron-rich moieties to the electron-deficient core (pyrimidine). The elongation of $\pi$-conjugation led to escalate the electron affinity, lower the ionization potential and hole reorganization energy. The hole reorganization energies of compounds ...

Our results demonstrate that strontium ranelate has structure-modifying activity in patients with knee osteoarthritis, with significantly smaller degradations in JSW over the study (p,0.001 for 1 g/day and p=0.018 for 2 g/day vs placebo). There were fewer patients with radiographical and radioclinical progression of osteoarthritis in the treatment groups. Additionally to this structural effect, symptomatic improvement was observed, with a significant impact on WOMAC total score and pain subscore (p=0.045 and p=0.028, respectively), and a trend towards improvement in global knee pain (p=0.065) at 2 g/day, but not 1 g/day. The safety profile of strontium ranelate was satisfactory, in line with knowledge of this agent.20 ,21 There was a slight mean increase in creatine phosphokinase in the treated groups as previously described for strontium ranelate.20 Pooled analysis in osteoporotic patients treated with strontium ranelate showed that increases were mainly mild, transient and reversible22; they ...

Nonvitamin K antagonist oral anticoagulant activity: challenges in measurement and reversal | Critical Care | Full TextNonvitamin K antagonist oral anticoagulant activity: challenges in measurement and reversal | Critical Care | Full Text
Four nonvitamin K antagonist oral anticoagulants (NOACs) are approved for the prevention of stroke in patients with nonvalvular atrial fibrillation and for the treatment of venous thromboembolism. These include the direct thrombin inhibitor dabigatran and the direct factor Xa inhibitors rivaroxaban, apixaban, and edoxaban. Bleeding is a complication for all anticoagulants and concerns regarding bleeding risk and the suitability of effective reversal strategies may be a barrier to their prescription. Despite the reduced risk of bleeding compared with vitamin K antagonists, questions persist regarding the management of bleeding related to NOAC use. To date, although a number of assays are responsive to NOACs, no single routine laboratory test has been identified to accurately measure the clinical anticoagulation state of patients on NOACs or established as a reliable predictor of bleeding risk. In addition, the establishment of a reliable human bleeding model to test novel inhibitors of the coagulation

Idarucizumab: The Antidote for Reversal of Dabigatran RadcliffeCardiologyIdarucizumab: The Antidote for Reversal of Dabigatran RadcliffeCardiology
Four non-vitamin K antagonist oral anticoagulants (NOACs), including the direct thrombin inhibitor dabigatran and the direct factor Xa inhibitors rivaroxaban, apixaban, and edoxaban, are currently licensed as alternatives to heparins and vitamin K antagonists for the prevention and treatment of venous thromboembolism and for the prevention of stroke in patients with nonvalvular atrial fibrillation. Dabigatran is the only NOAC that inhibits thrombin; the others inhibit factor Xa. All of the NOACs are at least as effective as vitamin K antagonists for the prevention of stroke in patients with atrial fibrillation and for the treatment of venous thromboembolism, and they are associated with less life-threatening bleeding, in particular less intracranial hemorrhage.1,2 Nonetheless, serious bleeding can occur with NOACs. In addition, patients taking NOACs may sustain trauma and may require urgent surgery or interventions. Consequently, the availability of specific reversal agents for NOACs could ...

Acidic zeolites like H-Y, H-ZSM-5, H-MCM-22 and H-MOR zeolites were found to be the selective adsorbents for the removal of thiophene from toluene or n-heptane as solvent. The competitive adsorption of toluene is found to influence the adsorption capacity for thiophene and is more predominant when high-alumina zeolites are used as adsorbents. This behaviour is also reflected by the results of the adsorption of thiophene on H-ZSM-5 zeolites with varied nSi/nAl ratios (viz. 13, 19 and 36) from toluene and n-heptane as solvents, respectively. UV-Vis spectroscopic results show that the oligomerization of thiophene leads to the formation of dimers and trimers on these zeolites. The oligomerization in acid zeolites is regarded to be dependent on the geometry of the pore system of the zeolites. The sulphur-containing compounds with more than one ring viz. benzothiophene, which are also present in substantial amounts in certain hydrocarbon fractions, are not adsorbed on H-ZSM-5 zeolites. This is ...

The new fluorocarbon-functionalized polythiophenes, in particular, α,ω-diperfluorohexylsexithiophene DFH-6T (1) can be straightforwardly prepared in high yield and purified by gradient sublimation. Introduction of perfluorocarbon chains on the thiophene core affords enhanced thermal stability and volatility, and increased electron affinity versus the fluorine-free analog 2. Evaporated films of 1, for example, behave as n-type semiconductors, and can be used to fabricate thin film transistors with FET mobilities on the order of ˜0.01 cm2/Vs-some of the highest reported to date for n-type organic semiconductors.

Density functional theory study of neutral and oxidized thiophene oligomers (Journal Article) | SciTech ConnectDensity functional theory study of neutral and oxidized thiophene oligomers (Journal Article) | SciTech Connect
The effect of oxidation on the energetics and structure of thiophene (Th) oligomers is studied with density functional theory at the B3PW91/6-311++G(d,p) level. Neutral n-Th oligomers (2 , n , 13) are gently curved planar chains. Ionization potential and electron affinity results show that n-Th oligomers are easier to be oxidized as their chain length increases. Oxidation states +2, +4, +6, and +8 are energetically stable in 12-Th. Upon oxidation the conjugated backbone of 12-Th switches from extended benzenoid phase to quinoid phase localized on groups of monomers regularly spaced along the chain. Oxidized states +2, +4, +6, and +8 of 12-Th display two +1e localized at the ends of their chains only because of the finite size of the chains. In 12-Th this end-effect extends over the two terminal monomers forming a positive-negative charge duet. This peculiar charge localization makes n-Th oligomers different from other conducting polymers with similar structure, such as polypyrrole. The spectrum ...

In the first part, the preparation and properties of chalcogen-containing vitamin E analogues are described. The sulfur compound 3,3,4,6,7-pentamethyl-2,3-dihydrobenzo[b]thiophene-5-ol was prepared by two different routes using ionic and radical chemistry. Interesting rearrangements were observed in the two synthetic pathways. A new methodology for the synthesis of dihydroselenophene and dihydrotellurophene derivatives is described. In the preparation of the vitamin E analogues 2,3-dihydrobenzo[b]selenophene-5-ol and 2,3-dihydrobenzo[b]tellurophene-5-ol a tellurium-mediated tandem SRN1/SHi sequence was suggested to be operative. 2,3-Dihydrobenzo[b]thiophene-5-ol and the vitamin E-like selenide 2-methyl-2-(4,8,12-trimethyl-tridecyl)-selenochroman-6-ol were prepared via intramolecular homolytic substitution at sulfur and selenium, respectively. The first rate constant for intramolecular homolytic substitution at tellurium is also reported (5x108 s-1 at 25 °C). The antioxidant profile for ...

BACKGROUND AND OBJECTIVES: Strontium ranelate is a medication indicated for the treatment of osteoporosis that presents concomitant anti-resorptive and osteoanabolic dual biological activity. However, the effects of strontium ranelate on alveolar bone have been poorly explored. Furthermore, to date, there are no data on the effects of this medication on alveolar bone loss (BL) during conditions of estrogen deficiency. Therefore, the aim of this study was to evaluate the effects of strontium ranelate on ligature-induced periodontitis in estrogen-deficient and estrogen-sufficient rats. METHODS: Ninety-six rats were assigned to one of the following groups: sham-surgery + water (estrogen-sufficient; n = 24); ovariectomy + water (estrogen-deficient; n = 24), sham-surgery + strontium ranelate (ranelate/estrogen-sufficient; n = 24) and; ovariectomy + strontium ranelate (ranelate/estrogen-deficient; n = 24). The rats received strontium ranelate or water from the 14th day after ovariectomy until the end ...

Evaluation of the Efficacy and Safety of Rivaroxaban Using a Computer Model for Blood CoagulationEvaluation of the Efficacy and Safety of Rivaroxaban Using a Computer Model for Blood Coagulation
Rivaroxaban is an oral, direct Factor Xa inhibitor approved in the European Union and several other countries for the prevention of venous thromboembolism in adult patients undergoing elective hip or knee replacement surgery and is in advanced clinical development for the treatment of thromboembolic disorders. Its mechanism of action is antithrombin independent and differs from that of other anticoagulants, such as warfarin (a vitamin K antagonist), enoxaparin (an indirect thrombin/Factor Xa inhibitor) and dabigatran (a direct thrombin inhibitor). A blood coagulation computer model has been developed, based on several published models and preclinical and clinical data. Unlike previous models, the current model takes into account both the intrinsic and extrinsic pathways of the coagulation cascade, and possesses some unique features, including a blood flow component and a portfolio of drug action mechanisms. This study aimed to use the model to compare the mechanism of action of rivaroxaban with that of

Previously, we reported that(R)−(−)−1−(benzo[b]thiophen−5−yl)−2−[2−(N, N−diethylamino)ethoxy]ethanol hydrochloride(T−588), a novel putative cognitive enhancer, stimulated noradrenaline(NA)release from rat cerebral cortical slices.In this study, we investigated the effects of T−588 compared to other secretagogues on NA release from PC12 cells.Addition of as little as 10 μM T−588 stimulated [,SUP,3,/SUP,H]NA release in a dose−dependent and an extracellular Ca,SUP,2+,/SUP,−independent manner from PC12 cells.Ten micromolar ionomycin−, 300 μM adenosine−5′−O−(γ−thiotriphosphate)− and 10 μM forskolin−induced extracellular Ca,SUP,2+,/SUP,−dependent [,SUP,3,/SUP,H]−NA release was further enhanced by 30 μM T−588.Cytosolic synaptophysin and 25−kDa synaptosome−associated protein immunoreactivity was increased by addition of T−588 in a dose−dependent manner.Interestingly, increases in synaptic vesicle−related proteins triggered by T−588 had ...

Novel oral anticoagulants offer equivalent or improved therapeutic profiles compared with warfarin, with less risk of bleeding, no interactions with food, and no need for routine laboratory monitoring. Caution must be exercised in using these drugs in certain patient populations, for example, renal insufficiency, those receiving additional antithrombotic therapy, those with questionable compliance, children, and those with a high risk of gastrointestinal bleeding. One of the novel oral anticoagulants, rivaroxaban, is a direct Factor Xa inhibitor, used to reduce risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation, deep vein thrombosis, and pulmonary embolism ...

Raltitrexed - WikipediaRaltitrexed - Wikipedia
Raltitrexed (Tomudex, TDX, ZD 1694) is an antimetabolite drug used in cancer chemotherapy. It is an inhibitor of thymidylate synthase, and is manufactured by AstraZeneca. Used in treatment of colorectal cancer since 1998. It may also be used in the treatment of malignant mesothelioma. Raltitrexed is chemically similar to folic acid and is in the class of chemotherapy drugs called folate antimetabolites, which inhibit one or more of three enzymes that use folate and derivatives as substrates: DHFR, GARFT and thymidylate synthase. Raltitrexed is fully active after polyglutamylation, which allows cellular retention of the drug. By inhibiting Thymidylate synthase (TS), thus formation of precursor pyrimidine nucleotides, raltitrexed prevents the formation of DNA and RNA, which are required for the growth and survival of both normal cells and cancer cells. Inhibition of L1210 cell growth in culture IC50 = 9 nM, is one of the strongest antimetabolites in use. Structure and phase I clinical trial of the ...

Results XAMOS enrolled 17,701 patients; the safety population included 17,413 patients, of whom 8778 received rivaroxaban and 8635 received SOC (81.7% low molecular weight heparin). Baseline patient demographics and use of cytochrome P450 (CYP) 3A4 inhibitors or inducers and platelet aggregation inhibitors (PAIs) before surgery were similar between groups; these drugs were used less frequently after surgery. There was a significant reduction in the incidence of symptomatic thromboembolic events in the rivaroxaban group compared with the SOC group, with numerically but not statistically higher incidence of major bleeding events. Concomitant use of PAIs was associated with higher incidences of symptomatic thromboembolic and any bleeding events compared with non-use in both the rivaroxaban and the SOC groups (Table).. ...

Rivaroxaban better than aspirin at preventing DVT | Good Health CareRivaroxaban better than aspirin at preventing DVT | Good Health Care
An international research team has found that the blood thinner rivaroxaban is as safe as aspirin, and more effective at preventing recurrence of life-threatening blood clots in the legs and lungs.. The large international study of 3,396 patients with venous thromboembolism in 31 countries, published the New England Journal of Medicine. shows that rivaroxaban is more effective than aspirin.. Not only that, but in testing two doses of rivaroxaban, we found that we have the option of lowering the daily dose for extended treatment, said Dr. Jeffrey Weitz, principal investigator of the study and professor of medicine and biochemistry and biomedical sciences at the Michael G. DeGroote School of Medicine at McMaster University. This will ease the long-term concerns of both patients and their doctors.. During the study from March 2014 to March 2016, patients received either a daily 20mg dose of rivaroxaban, a 10mg dose of rivaroxaban, or a 100 mg dose of aspirin. They took these medications for up ...
