The in-vitro activity of linezolid (U-100766) and tentative breakpoints. (1/1402)

The in-vitro activity of linezolid, a novel oxazolidinone, was investigated in comparison with those of amoxycillin, cefuroxime, quinupristin/dalfopristin, trovafloxacin and vancomycin against 420 recent Gram-positive and anaerobic clinical isolates. Linezolid was equally active (MIC90 1 mg/L) against methicillin-susceptible and -resistant Staphylococcus aureus. It demonstrated uniform activity against streptococci and enterococci and no cross-resistance with other agents. The time-kill kinetic data demonstrated that the in-vitro activity of linezolid was predominantly bacteriostatic; slow bactericidal activity was only observed at the higher concentration with streptococci. An increase in inoculum from 10(4) to 10(6) cfu on selected strains had little effect on the MICs (MIC90 within one dilution step) of linezolid and an increase in inoculum from 10(5) to 10(7) cfu/mL had no notable effect on the in-vitro bactericidal activity. A tentative linezolid breakpoint of 2 mg/L was chosen after analysis of distribution of susceptibilities.  (+info)

Novel structural templates for estrogen-receptor ligands and prospects for combinatorial synthesis of estrogens. (2/1402)

BACKGROUND: The development of estrogen pharmaceutical agents with appropriate tissue-selectivity profiles has not yet benefited substantially from the application of combinatorial synthetic approaches to the preparation of structural classes that are known to be ligands for the estrogen receptor (ER). We have developed an estrogen pharmacophore that consists of a simple heterocyclic core scaffold, amenable to construction by combinatorial methods, onto which are appended 3-4 peripheral substituents that embody substructural motifs commonly found in nonsteroidal estrogens. The issue addressed here is whether these heterocyclic core structures can be used to prepare ligands with good affinity for the ER. RESULTS: We prepared representative members of various azole core structures. Although members of the imidazole, thiazole or isoxazole classes generally have weak binding for the ER, several members of the pyrazole class show good binding affinity. The high-affinity pyrazoles bear close conformational relationship to the nonsteroidal ligand raloxifene, and they can be fitted into the ligand-binding pocket of the ER-raloxifene X-ray structure. CONCLUSIONS: Compounds such as these pyrazoles, which are novel ER ligands, are well suited for combinatorial synthesis using solid-phase methods.  (+info)

Protein phosphatase 2A interacts with the 70-kDa S6 kinase and is activated by inhibition of FKBP12-rapamycinassociated protein. (3/1402)

The FKBP12-rapamycin-associated protein (FRAP; also called RAFT1/mTOR) regulates translation initiation and entry into the cell cycle. Depriving cells of amino acids or treating them with the small molecule rapamycin inhibits FRAP and results in rapid dephosphorylation and inactivation of the translational regulators 4E-BP1(eukaryotic initiation factor 4E-binding protein 1) and p70(s6k) (the 70-kDa S6 kinase). Data published recently have led to the view that FRAP acts as a traditional mitogen-activated kinase, directly phosphorylating 4E-BP1 and p70(s6k) in response to mitogenic stimuli. We present evidence that FRAP controls 4E-BP1 and p70(s6k) phosphorylation indirectly by restraining a phosphatase. A calyculin A-sensitive phosphatase is required for the rapamycin- or amino acid deprivation-induced dephosphorylation of p70(s6k), and treatment of Jurkat I cells with rapamycin increases the activity of the protein phosphatase 2A (PP2A) toward 4E-BP1. PP2A is shown to associate with p70(s6k) but not with a mutated p70(s6k) that is resistant to rapamycin- and amino acid deprivation-mediated dephosphorylation. FRAP also is shown to phosphorylate PP2A in vitro, consistent with a model in which phosphorylation of PP2A by FRAP prevents the dephosphorylation of 4E-BP1 and p70(s6k), whereas amino acid deprivation or rapamycin treatment inhibits FRAP's ability to restrain the phosphatase.  (+info)

The Rho-related protein Rnd1 inhibits Ca2+ sensitization of rat smooth muscle. (4/1402)

1. The small GTP-binding Rho proteins are involved in the agonist-induced Ca2+ sensitization of smooth muscle. The action and the expression of Rnd1, a new member of the Rho protein family constitutively bound to GTP, has been studied in rat smooth muscle. 2. Recombinant prenylated Rnd1 (0.01-0.1 mg ml-1) dose dependently inhibited carbachol- and GTPgammaS-induced Ca2+ sensitization in beta-escin-permeabilized ileal smooth muscle strips but had no effect on the tension at submaximal [Ca2+] (pCa 6.3). Rnd1 inhibited GTPgammaS-induced tension without shifting the dose-response curves to GTPgammaS. 3. pCa-tension relationships were not modified by Rnd1 and the rise in tension induced through the inhibition of myosin light chain phosphatase by calyculin A was not affected by Rnd1. 4. The Ca2+ sensitization induced by recombinant RhoA was completely abolished when RhoA and Rnd1 were applied together. 5. Rnd1 was expressed at a low level in membrane fractions prepared from intestinal or arterial smooth muscles. The expression of Rnd1 was strongly increased in ileal and aortic smooth muscle from rats treated with progesterone or oestrogen. Progesterone-treated ileal muscle strips showed a decrease in agonist-induced Ca2+ sensitization. 6. The present study shows that (i) Rnd1 inhibits agonist- and GTPgammaS-induced Ca2+ sensitization of smooth muscle by specifically interfering with a RhoA-dependent mechanism and (ii) an increase in Rnd1 expression may account, at least in part, for the steroid-induced decrease in agonist-induced Ca2+ sensitization.  (+info)

Cardiovascular effects of rilmenidine, moxonidine and clonidine in conscious wild-type and D79N alpha2A-adrenoceptor transgenic mice. (5/1402)

1. We investigated the cardiovascular effects of rilmenidine, moxonidine and clonidine in conscious wild-type and D79N alpha2A-adrenoceptor mice. The in vitro pharmacology of these agonists was determined at recombinant (human) alpha2-adrenoceptors and at endogenous (dog) alpha2A-adrenoceptors. 2. In wild-type mice, rilmenidine, moxonidine (100, 300 and 1000 microg kg(-1), i.v.) and clonidine (30, 100 and 300 microg kg(-1), i.v.) dose-dependently decreased blood pressure and heart rate. 3. In D79N alpha2A-adrenoceptor mice, responses to rilmenidine and moxonidine did not differ from vehicle control. Clonidine-induced hypotension was absent, but dose-dependent hypertension and bradycardia were observed. 4. In wild-type mice, responses to moxonidine (1 mg kg(-1), i.v.) were antagonized by the non-selective, non-imidazoline alpha2-adrenoceptor antagonist, RS-79948-197 (1 mg kg(-1), i.v.). 5. Affinity estimates (pKi) at human alpha2A-, alpha2B- and alpha2C-adrenoceptors, respectively, were: rilmenidine (5.80, 5.76 and 5.33), moxonidine (5.37, <5 and <5) and clonidine (7.21, 7.16 and 6.87). In a [35S]-GTPgammaS incorporation assay, moxonidine and clonidine were alpha2A-adrenoceptor agonists (pEC50/intrinsic activity relative to noradrenaline): moxonidine (5.74/0.85) and clonidine (7.57/0.32). 6. In dog saphenous vein, concentration-dependent contractions were observed (pEC50/intrinsic activity relative to noradrenaline): rilmenidine (5.83/0.70), moxonidine (6.48/0.98) and clonidine (7.22/0.83). Agonist-independent affinities were obtained with RS-79948-197. 7. Thus, expression of alpha2A-adrenoceptors is a prerequisite for the cardiovascular effects of moxonidine and rilmenidine in conscious mice. There was no evidence of I1-imidazoline receptor-mediated effects. The ability of these compounds to act as alpha2A-adrenoceptor agonists in vitro supports this conclusion.  (+info)

Activities of several novel oxazolidinones against Mycobacterium tuberculosis in a murine model. (6/1402)

The activities of linezolid, eperezolid, and PNU-100480 were evaluated in a murine model of tuberculosis. Approximately 10(7) viable Mycobacterium tuberculosis ATCC 35801 organisms were given intravenously to 4-week-old outbred CD-1 mice. In the first study, treatment was started 1 day postinfection and was given by gavage for 4 weeks. Viable cell counts were determined from homogenates of spleens and lungs. PNU-100480 was as active as isoniazid. Linezolid was somewhat less active than PNU-100480 and isoniazid. Eperezolid had little activity in this model. In the next two studies, treatment was started 1 week postinfection. A dose-response study was performed with PNU-100480 and linezolid (both at 25, 50, and 100 mg/kg of body weight). PNU-100480 was more active than linezolid, and its efficacy increased with an escalation of the dose. Subsequently, the activity of PNU-100480 alone and in combination with rifampin or isoniazid was evaluated and was compared to that of isoniazid-rifampin. The activity of PNU-100480 was similar to that of isoniazid and/or rifampin in the various combinations tested. Further evaluation of these oxazolidinones in the murine test system would be useful prior to the development of clinical studies with humans.  (+info)

TNF-alpha and IL-1alpha induce heme oxygenase-1 via protein kinase C, Ca2+, and phospholipase A2 in endothelial cells. (7/1402)

Heme oxygenase-1 (HO-1), an enzyme important in protection against oxidant stress, is induced in human vascular endothelial cells by the cytokines tumor necrosis factor-alpha (TNF-alpha) and interleukin-1alpha (IL-1alpha). However, the signaling mediators that regulate the induction are not known. This study examined the involvement of protein kinase C (PKC), phospholipase A2 (PLA2), calcium, and oxidants in cytokine induction of HO-1. Acute exposure to the PKC activator phorbol 12-myristate 13-acetate (PMA) stimulated HO-1 mRNA. However, prolonged exposure, which downregulates most PKC isoforms, blocked induction of HO-1 mRNA by IL-1alpha and TNF-alpha. Additionally, the phosphatase inhibitors okadaic acid and calyculin enhanced cytokine induction of HO-1. Mepacrine, a PLA2 inhibitor, prevented HO-1 induction by cytokine, suggesting a role for arachidonate, the product of PLA2 hydrolysis of phospholipids, in HO-1 expression. The intracellular calcium chelator 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid acetoxymethyl ester (BAPTA-AM) blocked cytokine induction of HO-1. Paradoxically, the calcium ionophore A-23187 prevented HO-1 induction by cytokine but not by PMA. Finally, the oxidant scavenger N-acetylcysteine inhibited HO-1 induction by cytokines. These results demonstrate that TNF-alpha and IL-1alpha induction of HO-1 requires PKC-mediated phosphorylation and PLA2 activation as well as oxidant generation.  (+info)

Regulation of Na+-K+-2Cl- cotransport in turkey red cells: the role of oxygen tension and protein phosphorylation. (8/1402)

1. Na+-K+-2Cl- cotransport (NKCC) was studied in turkey red cells using Na+ dependence or bumetanide sensitivity of 86Rb+ influx to monitor activity of the transporter. 2. Deoxygenation was the major physiological stimulus for NKCC activity: oxygen tensions (PO2) over the physiological range modulated the transporter, with a PO2 for half-maximal activation of about 41 mmHg (n = 3). In air, activity of NKCC was also stimulated by shrinkage and isoproteronol (isoprenaline, 5 microgr;M). By contrast, in deoxygenated cells, although the transporter activity was markedly elevated, it was no longer sensitive to volume or beta-adrenergic stimulation. 3. Calyculin A, a protein phosphatase inhibitor, stimulated cotransport with a lag of about 5 min. N-Ethylmaleimide (NEM) inhibited cotransport and also blocked the stimulatory effect of calyculin A if administered before calyculin A. Stimulation by calyculin A and deoxygenation were not additive. Staurosporine (2 microM) inhibited deoxygenated-stimulated K+ influxes, but not those stimulated by calyculin A. NEM added during calyculin A stimulation, i.e. during the 5 min lag, caused transport activity to be clamped at levels intermediate between maximal (calyculin A alone) and control. Cells treated with calyculin A alone or with calyculin A followed by NEM were no longer sensitive to volume, isoproteronol or PO2. 4. The results have characterized the interaction between deoxygenation and other stimuli of NKCC activity. They have also shown that it is possible to manipulate the transporter in a reciprocal way to that shown previously for K+-Cl- cotransport.  (+info)

Environmental compounds can promote epigenetic transgenerational inheritance of adult-onset disease in subsequent generations following ancestral exposure during fetal gonadal sex determination. The current study examined the ability of dioxin (2,3,7,8-tetrachlorodibenzo[p]dioxin, TCDD) to promote epigenetic transgenerational inheritance of disease and DNA methylation epimutations in sperm. Gestating F0 generation females were exposed to dioxin during fetal day 8 to 14 and adult-onset disease was evaluated in F1 and F3 generation rats. The incidences of total disease and multiple disease increased in F1 and F3 generations. Prostate disease, ovarian primordial follicle loss and polycystic ovary disease were increased in F1 generation dioxin lineage. Kidney disease in males, pubertal abnormalities in females, ovarian primordial follicle loss and polycystic ovary disease were increased in F3 generation dioxin lineage animals. Analysis of the F3 generation sperm epigenome identified 50 differentially DNA

Ligands containing a chiral 2-oxazoline ring are used in asymmetric catalysis due to their facile synthesis, wide range of forms and effectiveness for many types of catalytic transformation.[23][24] 2-Substituted oxazolines can be prepared by many methods and possess a moderately hard N-donor. Chirality is easily incorporated by using 2-amino alcohols prepared by the reduction of amino acids; which are both optically pure and inexpensive. As the stereocentre in such oxazolines is adjacent to the coordinating N-atom, it can influence the selectivity of processes occurring at the metal centre. The ring is thermally stable[25] and resistant to nucleophiles, bases, radicals, and weak acids[26] as well as being fairly resistant to hydrolysis and oxidation;[7] thus it can be expected to remain stable in a wide range of reaction conditions. Major classes of oxazoline based ligand include: ...

This study focuses on the cytoskeleton during these calyculin-A-induced morphological changes. Stress fibres disappear as the cells begin to round and aggregates of actin are formed towards the apical surface of the cell. These aggregates condense, in the detached cells, to form the ball structure of approximately 3 μm diameter. Between the ball and the nucleus are cables of intermediate filaments that appear to ...

1219 Disorazole C1 is a potent, cytotoxic natural product, with IC50 values of , 20 nM in a variety of cancer cell lines. The addition of disorazole C1 disrupted microtubules in cells as early as 24 h after treatment, causing multinucleation and disorganized microtubules at interphase and misaligned chromosomes at the metaphase plate during mitosis. A549 cells that survived a 7 day treatment of disorazole C1 displayed an enlarged, flattened morphology similar to senescent cells treated with doxorubicin. These surviving cells displayed the characteristic β-galactosidase staining at pH 6.0 seen in senescent cells and changes in cell cycle markers indicative of premature or hypermitogenic senescence. A549 cells treated with the IC50 concentration of disorazole C1 (2 nM) for 7 days had increased protein levels of cyclin D, p53 and cyclin-dependent kinase inhibitor p21 as detected by Western blot. This resulted in decreased phosphorylation of Rb (Ser780) and a decrease in total Rb protein levels. A ...

Ancestral environmental exposures have previously been shown to promote epigenetic transgenerational inheritance and influence all aspects of an individuals life history. In addition, proximate life events such as chronic stress have documented effects on the development of physiological, neural, and behavioral phenotypes in adulthood. We used a systems biology approach to investigate in male rats the interaction of the ancestral modifications carried transgenerationally in the germ line and the proximate modifications involving chronic restraint stress during adolescence. We find that a single exposure to a common-use fungicide (vinclozolin) three generations removed alters the physiology, behavior, metabolic activity, and transcriptome in discrete brain nuclei in descendant males, causing them to respond differently to chronic restraint stress. This alteration of baseline brain development promotes a change in neural genomic activity that correlates with changes in physiology and behavior, ...

On December 24th, Prof. Dr. Albert van Leusen passed away at the age of 86. From 1955 to 1998, Prof. van Leusen was appointed at our university and from 1980, he was full professor. Albert van Leusen carried out his PhD under Prof. J. Strating, and was, like his promotor, a synthetic chemist pur sang. His primary focus was the development of methods in synthesis in the area of heterocyclic chemistry. His research led to the development of tosylmethyl isocyanide, TosMIC, in 1972. This reagent became very popular as it enabled the efficient synthesis of oxazolidines, oxazoles, indoles, pyrroles, thiazoles and triazoles. The van Leusen reaction that bears his name is still one of the most efficient synthetic methods for the preparation of imidazoles. The popularity of TosMIC increased further with the advent of multicomponent reactions, a frequently used method for the synthesis of drug-like compounds. In memory of his promotor Prof. J. Strating, van Leusen took the initiative to establish the ...

Some background first……Im continuing to juice daily and take enzymes to keep the digestion process working properly to keep my blood clean. What does that mean? And what is the difference of enzymes and eating healthy foods? Big difference. To greatly simplify it, my friend and mentor in my quest to rid myself of this disease, Tom, explained this to me. The white blood cells exist to fight virus and infection by attacking foreign stuff in the blood. When food particles make it into the bloodstream as a result of improper digestion, the white blood cells have to finish off the digestion process to clean the blood out. This reduces the cells ability to fight infection, and when that work of the white cells is overloaded, it leads to sickness, flu, colds, etc., and for some of us unlucky ones, more serious disease. Pretty much every adult onset disease has this root cause in common. In short, if the white cells are chomping food, theyre not chomping disease. Sorry for the crude explanation. ...

Check-out the last paragraph of Fridays press release from Inovio Biomedical:. Inovio Biomedical Corp., maker of VGX-3100-a DNA vaccine targeting the E6 and E7 proteins of human papillomavirus (HPV) types 16 and 18 and is delivered via in vivo electroporation. Similar to previously reported data from the initial lowest dose cohort of this phase I trial, the vaccine was found to be generally safe and well tolerated. While previously reported data showed significant cellular and humoral immune responses, data from this second, intermediate dose group highlighted a significantly increased and dose-related immune response specific to the antigens targeted by the vaccine.. We are extremely pleased with the safety and tolerability profile of VGX-3100. Furthermore, analyses of the vaccinated subjects from the first two cohorts indicate that this vaccine is highly immunogenic, generating antigen-specific T-cell and antibody responses that are amongst the highest reported from any previous human ...

TY - JOUR. T1 - Cytoskeletal integrity in interphase cells requires protein phosphatase activity. AU - Eriksson, John. AU - Brautigan, null. AU - Vallee, null. AU - Olmsted, null. AU - Fujiki, null. AU - Goldman, null. PY - 1992. Y1 - 1992. N2 - Phosphorylation by protein kinases has been established as a key factor in the regulation of cytoskeletal structure. However, little is known about the role of protein phosphatases in cytoskeletal regulation. To assess the possible functions of protein phosphatases in this respect, we studied the effects of the phosphatase inhibitors calyculin A, okadaic acid, and dinophysistoxin 1 (35-methylokadaic acid) on BHK-21 fibroblasts. Within minutes of incubation with these inhibitors, changes are seen in the structural organization of intermediate filaments, followed by a loss of microtubules, as assayed by immunofluorescence. These changes in cytoskeletal structure are accompanied by a rapid and selective increase in vimentin phosphorylation on ...

A novel inhibitor of zipper-interacting protein kinase (ZIPK) was utilized to examine the involvement of ZIPK in the regulation of smooth muscle contraction. Pre-treatment of de-endothelialized rat caudal arterial smooth muscle strips with the pyrazolo[3,4-d]pyrimidinone inhibitor HS38 decreased the velocity of contraction (time to reach half-maximal force) induced by the phosphatase inhibitor calyculin A in the presence of Ca2+ without affecting maximal force development. This effect was reversed following washout of HS38 and correlated with a reduction in the rate of phosphorylation of LC20 (myosin 20-kDa regulatory light chains) but not of CPI-17 (protein kinase C-potentiated inhibitory protein for myosin phosphatase of 17 kDa), Par-4 (prostate apoptosis response-4) or MYPT1 (myosin phosphatase targeting subunit 1), all of which have been implicated in the regulation of vascular contractility. A structural analog of HS38, with inhibitory activity towards PIM3 kinase but not ZIPK, had no ...
Environmental factors during fetal development can induce a permanent epigenetic change in the germ line (sperm) that then transmits epigenetic transgenerational inheritance of adult-onset disease in the absence of any subsequent exposure. The epigenetic transgenerational actions of various environmental compounds and relevant mixtures were investigated with the use of a pesticide mixture (permethrin and insect repellant DEET), a plastic mixture (bisphenol A and phthalates), dioxin (TCDD) and a hydrocarbon mixture (jet fuel, JP8). After transient exposure of F0 gestating female rats during the period of embryonic gonadal sex determination, the subsequent F1-F3 generations were obtained in the absence of any environmental exposure. The effects on the F1, F2 and F3 generations pubertal onset and gonadal function were assessed. The plastics, dioxin and jet fuel were found to promote early-onset female puberty transgenerationally (F3 generation). Spermatogenic cell apoptosis was affected ...
A team of researchers at Wayne State University, the University of Alabama at Birmingham and the University of Pittsburgh was recently awarded nearly $2 million from the National Institute of Environmental Health Sciences of the National Institutes of Health to explore possible determinants of susceptibility to common diseases such as diabetes, atherosclerotic heart disease, and various cancers. All of these diseases are considered to be adult-onset pathologies, but the research team is exploring the possibility of origins during early periods of human development.
Befloxatone is a competitive and reversible inhibitor of monoamine oxidase-A (MAOI-A). The aim of the study was to characterize the in vivo properties of [11C]befloxatone and to validate its use as a ligand for the study of MAO-A by positron emission tomography (PET). PET studies were performed in baboons after i.v. injection of [11C]befloxatone (551 ± 70 MBq, i.e.14.9 ± 1.9 mCi). [11C]Befloxatone enters rapidly in the brain with a maximum uptake at 30 min. Brain concentration of the tracer is high in thalamus, striatum, pons and cortical structures (1.5-1.8% of injected dose per 100 ml of tissue), and lower in cerebellum (1.07% injected dose/100 ml). Nonsaturable uptake, obtained after a pretreatment with a high dose of nonlabeled befloxatone (0.4 mg/kg), is very low and represents only 3% of the total uptake. Brain uptake of [11C]befloxatone is not altered by a pretreatment of a high dose with lazabemide (0.5 mg/kg i.v.), a selective MAOI-B but is completely blocked by a pretreatment with ...

A large number of epidemiology studies have suggested genetics alone cannot fully explain many forms of disease and most individuals with a disease do not appear to have correlated genetic mutations. The current proposal investigates an additional molecular mechanism, environmental epigenetics, as a causal factor for the etiology of disease. Epigenetics being the molecular factors around DNA that regulate genome activity, independent of DNA sequence and classic genetic mechanisms. Epigenetic transgenerational inheritance allows environmentally induced epigenetic states to be transmitted to future generations. The central theme of the proposed research is to develop epigenetic biomarkers for early stage diagnostics for disease susceptibility, and develop diagnostics for direct and ancestral exposures that promote disease. The current paradigm in medicine today is Reactionary Medicine, which involves the treatment and therapy for a disease or condition after the pathology has developed. This ...

To assess the acute oral toxicity of CS-1246 rats (10/sex/group) were treated by oral gavage at doses 0, 2,100, 3000, 4,200 or 6,000 mg/kg (Parekh, C. 1980) Animals were observed frequently on the day of dosing, and daily thereafter for 14 days. Any unusual signs of toxicity or death were noted. Animals were subjected to a gross pathological examination as soon as possible after spontaneous death, or at the scheduled necropsy on day 14. The acute oral toxicity of CS-1246 is low with LD50levels in male and female rats at 5249 mg/kg (4503-6673 mg/kg), and 3674 mg/kg (3216-4197 mg/kg) respectively. The acute dermal toxicity of CS-1246 was tested in 5 male and 5 female Wistar rats at a dose of 2000 mg/kg body weight (Ravi, G. S. (2009)). All rats gained body weight through the observation period. No local skin reactions were observed. No pre-terminal deaths occurred and no abnormalities were detected at necropsy. The acute dermal toxicity in the rat is therefore greater than 2,000 mg/kg. In an acute ...
