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. Some of the novel designed compounds exhibited interesting anti-proliferative effects on two different cell lines.Show less , ...

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. Sulfoximine 17 is in fact sulfoximine derivative of benzo[b]thiophene. The comparison between the IR spectrum, 1H and 13C NMR spectra of sulfilimine 15 and sulfoximine 17 confirmed this is a new compound with the proposed structure ...

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..

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 ...

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,

We examined the thermal crystallization of deposited films made of 2,5-bis(4-biphenylyl)thiophene (BP1T) and 1,4-bis(5-phenylthiophen-2-yl)benzene (AC5), which are thiophene/phenylene co-oligomers (TPCOs). 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 ...

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.

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 structures of all the title compounds have been elucidated by elemental analysis, IR, MS, 1H-NMR and 13C-NMR. Generally, these findings represent a new class of sulfur and nitrogen moieties that should also be of interest as new materials.
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
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.
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 ...
TY - JOUR. T1 - Photochemical generation of radical cations of dithienothiophenes, condensed thiophene trimers, studied by laser flash photolysis. AU - Fujitsuka, Mamoru. AU - Sato, Tadatake. AU - Shimidzu, Takeo. AU - Watanabe, Akira. AU - Ito, Osamu. PY - 1997/2/6. Y1 - 1997/2/6. N2 - Photoinduced electron-transfer reactions between dithienothiophene (DTT) and the electron acceptors, p-dinitrobenzene (DNB) and CCl4, have been investigated using nanosecond laser flash photolysis and time-resolved fluoresence spectroscopy. Generation of the radical cations of DTTs and radical anion of DNB in acetonitrile solution was confirmed by transient absorption spectra in the visible and near-IR regions. Observed transient absorption bands corresponded to those of radical ions generated by γ irradiation in a frozen matrix. Electron transfer occurred both from the singlet and triplet excited states of DTT to DNB at the diffusion-controlled rate, ∼1010 M-1 s-1. When CCl4 was used as an acceptor, electron ...
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 ...
Context: The clinical introduction of new oral anticoagulants (NOACs) has stimulated the development of tests to quantify the effects of these drugs and manage complications associated with their use. Until recently, the only treatment choices for the prevention of venous thromboembolism in orthopedic surgical patients, as well as for stroke and systemic embolism in patients with atrial fibrillation, were vitamin K antagonists, antiplatelet drugs, and unfractionated and low-molecular-weight heparins. With the approval of NOACs, treatment options and consequent diagnostic challenges have expanded. Objective: To study the utility of thromboelastography (TEG) in monitoring and differentiating between 2 currently approved classes of NOACs, direct thrombin inhibitors (dabigatran) and factor Xa inhibitors (rivaroxaban and apixaban). Design: Blood samples from healthy volunteers were spiked with each NOAC in both the presence and absence of ecarin, and the effects on TEG were evaluated. Results: Both ...

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 ...

Y1 - 2006/12/1. N2 - Adsorptive desulfurization of a model fuel over CeO2-based adsorbents was conducted in a flowing adsorption system at 25 oC under ambient pressure without using H2 gas in order to evaluate the desulfurization performance of the adsorbent for producing ultra-low-sulfur fuel. For adsorption test, the capacity and selectivity of CeO2-based adsorbents for various sulfur compounds and the co-existing olefin and aromatic compound were used. Doping Ti and W into CeO2 significantly improved the sulfur removing capacity. The breakthrough sequence of the compounds over the CeO2-based adsorbents was, 1-C8 olefin °Ö toluene , thiophene , benzothiophene , 2-methyl benzothiophene , tetrahydrothiophene. By comparison of selectivity study and computational analysis, it was found that the electron ...

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 (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).. ...
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 ...
