Effects of eutypine, a toxin from Eutypa lata, on plant cell plasma membrane: Possible subsequent implication in disease development

Eutypine, 4-hydroxy-3-(3-methyl-3-butene-1-ynyl) benzaldehyde, is a toxin produced by Eutypa lata, the causal agent of eutypa dieback. An essential target of eutypine action lies at the plasmalemma as shown by the data obtained during this study on three experimental models (Beta vulgaris, Mimosa pudica, Vitis vinifera). The fungal toxin at 100 muM triggered a rapid dose-dependent hyperpolarization of the membrane potential in M. pudica pulvinar cells. It also enhanced proton permeability in plant tissues or in purified plasma membrane vesicles (PMV) without modification of the H+-ATPase activity. As a physiological consequence, eutypine hindered sucrose and valine absorption by PMV and plant tissues. In all these situations, eutypine behaved like a protonophoric compound, such as dinitrophenol (DNP) used at 10 muM, and acted specifically since eutypinol, an inactive derivative, only triggered very limited effects at a 100-muM concentration. Eutypine did not modify phenylalanine ammonia lyase (PAL, EC 4.3.1.5) activity, suggesting that its toxic action has no after-effect on the secondary metabolism.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 695-53-4, you can also check out more blogs about695-53-4

Alterations in mouse embryo intracellular pH by DMO during culture impair implantation and fetal growth

The preimplantation embryo is highly susceptible to in-vitro stress, and although this does not necessarily perturb blastocyst development, it can significantly affect embryo physiology and the ability to form a viable pregnancy. This study determined that the preimplantation mouse embryo is highly sensitive to a small decrease in intracellular pH (<0.2 pH units). Embryos cultured in media containing a weak acid (5,5-dimethyl-2,4-oxazolidinedione; DMO) formed blastocysts with decreased cell number and inner cell mass number, as well as increased apoptosis, even though blastocyst development and morphology were unchanged. Interestingly, the effects were similar regardless of whether the pH stress was present for a short-term 'acute' exposure (during the zygote to 2-cell, or 2-cell to 8-cell division) or an extended 'chronic' period of time (continually from the zygote to the blastocyst stage). Exposure to DMO during the first cleavage division did not alter implantation; however, fetal weight and crown-rump length were significantly decreased (P < 0.05). In contrast, continuous exposure to DMO throughout preimplantation development reduced not only implantation but also fetal weight and crown-rump length. This study highlights the importance of correct intracellular pH and demonstrates that slight deviations can significantly impact embryo development and viability. The early embryo is known to be sensitive to its environment. This study determined the effect of a small alteration to pH of the culture environment on the ability of the embryo to grow and develop into a successful pregnancy. We found that the younger the embryo was the less capable it was to cope with the stress. Also embryos that appeared normal by observation were often not and by closer examination were showing signs of stress within the cells of the embryo resulting in poor pregnancy outcomes.

N-Acyl and N-sulfonyloxazolidine-2,4-diones are pseudo-irreversible inhibitors of serine proteases

The synthesis, inhibitory activity and mode of action of oxazolidine-2,4-diones against porcine pancreatic elastase, here used as a model for human neutrophil elastase, are reported. The nature of N-substitution at the oxazolidine-2,4-dione scaffold has large effect on the inhibitory potency against elastase. N-Acyl and N-sulfonyloxazolidine-2,4-diones emerged as potent pseudo-irreversible inhibitors, displaying high second-order rate constants for PPE inactivation. The title compounds were also shown to be potent inhibitors of human neutrophil elastase (HNE) and proteinase-3, and weak inhibitors of human cathepsin G. The results herein presented show that the oxazolidine-2,4-diones represent a new promising class of serine protease inhibitors.

Targeted repositioning identifies drugs that increase fibroblast growth factor 20 production and protect against 6-hydroxydopamine-induced nigral cell loss in rats

Endogenous fibroblast growth factor 20 (FGF20) supports maintenance of dopaminergic neurones within the nigrostriatal pathway. Moreover, direct intracerebral infusion of FGF20 protects against nigrostriatal tract loss in the 6-hydroxydopamine lesion rat model of Parkinson?s disease. Increasing endogenous FGF20 production might provide a less-invasive, more translational way of providing such protection. Accordingly, we adopted a targeted repositioning approach to screen for candidate FDA-approved drugs with potential to enhance endogenous FGF20 production in brain. In silico interrogation of the Broad Institute?s Connectivity Map database (CMap), revealed 50 candidate drugs predicted to increase FGF20 transcription, 16 of which had profiles favourable for use in Parkinson?s disease. Of these, 11 drugs were found to significantly elevate FGF20 protein production in MCF-7 cells, between two- and four-fold. Four drugs were selected for examination in vivo. Following oral dosing in rats for 7 days, salbutamol and triflusal, but not dimethadione or trazodone, significantly elevated FGF20 levels in the nigrostriatal tract. Preliminary examination in the unilateral 6-hydroxydopamine-lesioned rat revealed a modest but significant protection against nigral cell loss with both drugs. Our data demonstrate the power of targeted repositioning as a method to identify existing drugs that may combat disease progression in Parkinson?s by boosting FGF20 levels.

The novel antiepileptic drug levetiracetam (ucb L059) appears to act via a specific binding site in CNS membranes

Levetiracetam ((S)-alpha-ethyl-2-oxo-pyrrolidine acetamide, ucb L059) is a novel potential antiepileptic agent presently in clinical development with unknown mechanism of action. The finding that its anticonvulsant activity is highly stereoselective (Gower et al., 1992) led us to investigate the presence of specific binding sites for [3H]levetiracetam in rat central nervous system (CNS). Binding assays, performed on crude membranes, revealed the existence of a reversible, saturable and stereoselective specific binding site. Results obtained in hippocampal membranes suggest that [3H]levetiracetam labels a single class of binding sites (n(H) = 0.92 ¡À 0.06) with modest affinity (K(d) = 780 ¡À 115 nM) and with a high binding capacity (B(max) = 9.1 ¡À 1.2 pmol/mg protein). Similar K(d) and B(max) values were obtained in other brain regions (cortex, cerebellum and striatum). ucb L060, the (R) enantiomer of levetiracetam, displayed about 1000 times less affinity for these sites. The binding of [3H]levetiracetam is confined to the synaptic plasma membranes in the central nervous system since no specific binding was observed in a range of peripheral tissues including heart, kidneys, spleen, pancreas, adrenals, lungs and liver. The commonly used antiepileptic drugs carbamazepine, phenytoin, valproate, phenobarbital and clonazepam, as well as the convulsant agent t-butylbicyclophosphorothionate (TBPS), picrotoxin and bicuculline did not displace [3H]levetiracetam binding. However, ethosuximide (pK(i) = 3.5 ¡À 0.1), pentobarbital (pK(i) = 3.8 ¡À 0.1), pentylenetetrazole (pK(i) = 4.1 ¡À 0.1) and bemegride (pK(i) = 5.0 ¡À 0.1) competed with [3H]levetiracetam with pK(i) values comparable to active drug concentrations observed in vitro. Structurally related compounds, including piracetam and aniracetam, also displaced [3H]levetiracetam binding. (S) Stereoisomer homologues of levetiracetam demonstrated a rank order of affinity for [3H]levetiracetam binding in correlation with their anticonvulsant activity in the audiogenic mouse test (r2 = 0.84, n = 12, P< 0.0001). These results support a possible role of this binding site in the anticonvulsant activity of levetiracetam and substantiate the singular pharmacological profile of this compound. This site remains however to be further characterised. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C5H7NO3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 695-53-4, in my other articles.

Dormancy in temperate fruit trees in a global warming context: A review

Dormancy is the mechanism that plants use to protect sensitive tissue from unfavourable climatic conditions. In a changing global environment, temperate fruit crop adaptation might be at risk due to changes in temperature cues. A complete picture of dormancy is shown in this review, using results from the early, pioneering work to the molecular basis, also emphasising dormancy modelling and measurement and their implication in temperate fruit production. This description is completed by the variability that climatic change might induce in plants through direct or indirect changes in dormancy. Future avenues for the correct adaptation of temperate fruit crops are proposed that span basic questions, from temperate fruit distribution to more-applied questions of dormancy, such as application of rest-breaking agents, depth-of-dormancy markers, breeding strategies, cross-pollination and host-pest interaction. In the context of global climate change, a linkage among the cited fields is intended in this review in order to raise awareness in the scientific community.

Ibudilast attenuates doxorubicin-induced cytotoxicity by suppressing formation of TRPC3 channel and NADPH oxidase 2 protein complexes

Background and Purpose: Doxorubicin is a highly effective anticancer agent but eventually induces cardiotoxicity associated with increased production of ROS. We previously reported that a pathological protein interaction between TRPC3 channels and NADPH oxidase 2 (Nox2) contributed to doxorubicin-induced cardiac atrophy in mice. Here we have investigated the effects of ibudilast, a drug already approved for clinical use and known to block doxorubicin-induced cytotoxicity, on the TRPC3-Nox2 complex. We specifically sought evidence that this drug attenuated doxorubicin-induced systemic tissue wasting in mice. Experimental Approach: We used the RAW264.7 macrophage cell line to screen 1,271 clinically approved chemical compounds, evaluating functional interactions between TRPC3 channels and Nox2, by measuring Nox2 protein stability and ROS production, with and without exposure to doxorubicin. In male C57BL/6 mice, samples of cardiac and gastrocnemius muscle were taken and analysed with morphometric, immunohistochemical, RT-PCR and western blot methods. In the passive smoking model, cells were exposed to DMEM containing cigarette sidestream smoke. Key Results: Ibudilast, an anti-asthmatic drug, attenuated ROS-mediated muscle toxicity induced by doxorubicin treatment or passive smoking, by inhibiting the functional interactions between TRPC3 channels and Nox2, without reducing TRPC3 channel activity. Conclusions and Implications: These results indicate a common mechanism underlying induction of systemic tissue wasting by doxorubicin. They also suggest that ibudilast could be repurposed to prevent muscle toxicity caused by anticancer drugs or passive smoking.

Topological virtual screening: A way to find new anticonvulsant drugs from chemical diversity

A topological virtual screening (tvs) test is presented, which is capable of identifying new drug leaders with anticonvulsant activity. Molecular structures of both anticonvulsant-active and non active compounds, extracted from the Merck Index database, were represented using topological indexes. By means of the application of a linear discriminant analysis to both sets of structures, a topological anticonvulsant model (tam) was obtained, which defines a connectivity function. On the basis of this model, 41 new structures with anticonvulsant activity have been identified by a topological virtual screening.
