N-Substituted analogues of S-nitroso-N-acetyl-D,L-penicillamine: chemical stability and prolonged nitric oxide mediated vasodilatation in isolated rat femoral arteries. (1/84)

Previous studies show that linking acetylated glucosamine to S-nitroso-N-acetyl-D,L-penicillamine (SNAP) stabilizes the molecule and causes it to elicit unusually prolonged vasodilator effects in endothelium-denuded, isolated rat femoral arteries. Here we studied the propanoyl (SNPP; 3 carbon side-chain), valeryl (SNVP; 5C) and heptanoyl (SNHP; 7C) N-substituted analogues of SNAP (2C), to further investigate other molecular characteristics that might influence chemical stability and duration of vascular action of S-nitrosothiols. Spectrophotometric analysis revealed that SNVP was the most stable analogue in solution. Decomposition of all four compounds was accelerated by Cu(II) and cysteine, and neocuproine, a specific Cu(I) chelator, slowed decomposition of SNHP. Generation of NO from the compounds was confirmed by electrochemical detection at 37 degrees C. Bolus injections of SNAP (10 microl; 10(-8)-10(-3) M) into the perfusate of precontracted, isolated rat femoral arteries taken from adult male Wistar rats (400-500 g), caused concentration-dependent, transient vasodilatations irrespective of endothelial integrity. Equivalent vasodilatations induced by SNVP and SNHP were transient in endothelium-intact vessels but failed to recover to pre-injection pressures at moderate and high concentrations (10(-6)-10(-3) M) in those denuded of endothelium. This sustained effect (> 1 h) was most prevalent with SNHP and was largely reversed by the NO scavenger, haemoglobin. We suggest that increased lipophilicity of SNAP analogues with longer sidechains facilitates their retention by endothelium-denuded vessels; subsequent slow decomposition within the tissue generates sufficient NO to cause prolonged vasodilatation. This is a potentially useful characteristic for targeting NO delivery to areas of endothelial damage.  (+info)

A solvent model for simulations of peptides in bilayers. I. Membrane-promoting alpha-helix formation. (2/84)

We describe an efficient solvation model for proteins. In this model atomic solvation parameters imitating the hydrocarbon core of a membrane, water, and weak polar solvent (octanol) were developed. An optimal number of solvation parameters was chosen based on analysis of atomic hydrophobicities and fitting experimental free energies of gas-cyclohexane, gas-water, and octanol-water transfer for amino acids. The solvation energy term incorporated into the ECEPP/2 potential energy function was tested in Monte Carlo simulations of a number of small peptides with known energies of bilayer-water and octanol-water transfer. The calculated properties were shown to agree reasonably well with the experimental data. Furthermore, the solvation model was used to assess membrane-promoting alpha-helix formation. To accomplish this, all-atom models of 20-residue homopolypeptides-poly-Leu, poly-Val, poly-Ile, and poly-Gly in initial random coil conformation-were subjected to nonrestrained Monte Carlo conformational search in vacuo and with the solvation terms mimicking the water and hydrophobic parts of the bilayer. All the peptides demonstrated their largest helix-forming tendencies in a nonpolar environment, where the lowest-energy conformers of poly-Leu, Val, Ile revealed 100, 95, and 80% of alpha-helical content, respectively. Energetic and conformational properties of Gly in all environments were shown to be different from those observed for residues with hydrophobic side chains. Applications of the solvation model to simulations of peptides and proteins in the presence of membrane, along with limitations of the approach, are discussed.  (+info)

Agonist and potentiation actions of n-octanol on gamma-aminobutyric acid type A receptors. (3/84)

The n-octanol effects on the gamma-aminobutyric acid type A (GABAA) receptor were studied in human embryonic kidney 293 cells transfected with alpha1, beta2, and gamma2S subunit cDNAs. GABA-evoked currents had an EC50 of 13.3 +/- 1.7 microM and a Hill coefficient (nH) of 1.4 +/- 0.1. n-Octanol was also capable of evoking a small current with an EC50 of 1000 microM and an nH of 2. In addition, n-octanol modulated GABA-induced currents in a concentration-dependent manner. Coapplications of n-octanol increased peak currents evoked by 3 microM GABA with an EC50 of 190 microM and an nH of 1.8. The extent of potentiation decreased with increasing GABA concentrations and no potentiation was observed when n-octanol was coapplied with 1000 microM GABA. One-minute preapplication of 1000 microM n-octanol slightly potentiated 3 microM GABA-induced current, whereas it suppressed 300 microM GABA-induced current to 16% of the control, suggesting that 84% of the receptors underwent desensitization. Two models were used to explain n-octanol agonistic and potentiating actions on the alpha1beta2gamma2S GABAA receptor: n-octanol binds to multiple sites to exert multiple actions, or n-octanol acts as a partial agonist to manifest these actions. The partial agonist model is unique because it is a simpler model to explain n-octanol actions on the GABAA receptor.  (+info)

Functional gap junctions in the early sea urchin embryo are localized to the vegetal pole. (4/84)

Using the whole-cell voltage-clamp technique we have studied electrical coupling and dye coupling between pairs of blastomeres in 16- to 128-cell-stage sea urchin embryos. Electrical coupling was established between macromeres and micromeres at the 16-cell stage with a junctional conductance (G(j)) of 26 nS that decreased to 12 nS before the next cleavage division. G(j) between descendants of macromeres and micromeres was 12 nS falling to 8 nS in the latter half of the cell cycle. Intercellular current intensity was independent of transjunctional voltage, nondirectional, and sensitive to 1-octanol and therefore appears to be gated through gap junction channels. There was no significant coupling between other pairs of blastomeres. Lucifer yellow did not spread between these electrically coupled cell pairs and in fact significant dye coupling between nonsister cells was observed only at the 128-cell stage. Since 1-octanol inhibited electrical communication between blastomeres at the 16- to 64-cell stage and also induced defects in formation of the archenteron, it is possible that gap junctions play a role in embryonic induction.  (+info)

Quantitative trait loci influencing honeybee alarm pheromone levels. (5/84)

Quantitative trait loci (QTL) mapping procedures were used to identify loci that influence the levels of alarm pheromones found in the stinging apparatus of worker honeybees. An F1 queen was produced from a cross between a queen of European origin and a drone descended from an African subspecies. Haploid drones from the hybrid queen were individually backcrossed to European queens to produce 172 colonies. Samples of stings were taken from backcross workers of these colonies. Alarm pheromone levels were determined by gas chromatography. RAPD markers were scored from the haploid drone fathers of these colonies. The multiple-QTL model (MQM) of MapQTL was used to identify QTLs that influence the levels of four alarm pheromone components. Seven independent, potential QTLs were identified with LOD scores greater than two, and one at LOD 1.88. We identified one QTL for n-decyl acetate, three for n-octanol, four for isopentyl acetate, and one for hexyl acetate. One region of linkage group XI shows a strong influence on body size and the levels of three alarm pheromone components. This locus explained 40% of the variance for the amount of n-decyl acetate (LOD 6.57). In general, the QTLs influencing alarm pheromone levels were independent of previously identified loci that influenced the stinging behavior of these colonies. The only exception was a potential locus influencing levels of n-octanol, which was inversely correlated with stinging behavior.  (+info)

A cell type-specific and gap junction-independent mechanism for the herpes simplex virus-1 thymidine kinase gene/ganciclovir-mediated bystander effect. (6/84)

Tumor cells expressing the herpes simplex virus type 1 thymidine kinase (HSV-tk) gene are killed by nucleoside analogues such as ganciclovir (GCV). GCV affects not only the cells expressing HSV-tk but also neighboring cells that do not express the gene; this phenomenon commonly is called "bystander effect." GCV metabolites transfer via gap junctional intercellular communication (GJIC) accounts for the bystander effect in different cell lines, but other mechanisms have also been described. In this study, we analyzed the mechanisms of the bystander effect in two cell lines exhibiting different capacities of communication (DHD/K12 and 9L). The 9L cells exhibited a very good bystander effect, which was completely blocked by a long-term inhibitor of GJIC, 18 alpha-glycyrrhetinic acid. DHD/K12 cells exhibited a moderate bystander effect that was not abolished by 18 alpha-glycyrrhetinic acid or 1-octanol, another strong inhibitor of GJIC. Interestingly, we also observed a bystander effect in cultures where HSV-tk-expressing DHD/K12 cells were physically separated from their untransfected counterparts but grown in the same medium. Moreover, the transfer of filtered conditioned medium from GCV-treated HSV-tk-expressing DHD/K12 cells to DHD/K12 parental cells induced a decrease of survival in a concentration-dependent manner, suggesting that the bystander effect in this cell line was mediated by a soluble factor.  (+info)

Blocking and the detection of odor components in blends. (7/84)

Recent studies of olfactory blocking have revealed that binary odorant mixtures are not always processed as though they give rise to mixture-unique configural properties. When animals are conditioned to one odorant (A) and then conditioned to a mixture of that odorant with a second (X), the ability to learn or express the association of X with reinforcement appears to be reduced relative to animals that were not preconditioned to A. A recent model of odor-based response patterns in the insect antennal lobe predicts that the strength of the blocking effect will be related to the perceptual similarity between the two odorants, i.e. greater similarity should increase the blocking effect. Here, we test that model in the honeybee Apis mellifera by first establishing a generalization matrix for three odorants and then testing for blocking between all possible combinations of them. We confirm earlier findings demonstrating the occurrence of the blocking effect in olfactory learning of compound stimuli. We show that the occurrence and the strength of the blocking effect depend on the odorants used in the experiment. In addition, we find very good agreement between our results and the model, and less agreement between our results and an alternative model recently proposed to explain the effect.  (+info)

Effects of insulin-like growth factor-I on in vitro final oocyte maturation and ovarian steroidogenesis in striped bass, Morone saxatilis. (8/84)

Recombinant human (rh) insulin-like growth factor-I (IGF-I) was more potent than rhIGF-II at inducing in vitro germinal vesicle breakdown (GVBD), a marker for resumption of meiosis, in oocytes of striped bass. Treatment of ovarian fragments containing oocytes in intact follicles with rhIGF-I increased concentrations of estradiol-17beta and maturation-inducing steroid (MIS) 17,20beta, 21-trihydoxy-4-pregnen-3-one (20beta-S) in the culture medium and decreased testosterone levels. The follicles were too immature for oocytes to complete GVBD in response to 20beta-S (MIS incompetent) or hCG. Addition of 20beta-S to cultures did not increase the percentage of oocytes completing GVBD in response to rhIGF-I or rhIGF-II. Bovine insulin was without effect on GVBD or steroid production. Incubation of MIS-competent follicles with actinomycin D, cyanoketone, trilostane, 1-heptanol, or 1-octanol had no effect on rhIGF-I-induced GVBD, but attenuated hCG-induced GVBD and 20beta-S production. Cycloheximide inhibited rhIGF-I-induced GVBD. Collectively, these observations indicate that IGF-I can induce GVBD via MIS- and transcription-independent pathways without coupled gap junctions between oocytes and granulosa cells or among granulosa cells, but requires protein synthesis to do so. An rhIGF-I analogue that does not bind IGF-binding proteins, des(1,3)IGF-I, was more potent than rhIGF-I in inducing GVBD, suggesting ovarian IGF-binding proteins may inhibit IGF-I action.  (+info)

Objectives The occupational hazard of chemical absorption via dermal route was frequently assessed by evaluating the skin permeability (Kp) of chemical. In addition to in vitro testing using human skin, the quantitative structure-activity relationship (QSAR) has been employed as an alternative source to providing Kp. In the early Kp QSARs the octanol-water partition coefficient (log KOW) and molecular weight (MW) were commonly applied as dominant properties to describe transdermal transport of chemical. This study examined the efficacy of log KOW-/MW-based QSARs in Kp prediction.. ...

Transport of metals between aqueous phase and soil/sediment/suspended matter should be described on the basis of measured soil/water, sediment/water and suspended matter/water equilibrium partition coefficients (Kp), instead of using common mathematical relationships based on, for example, octanol-water partition coefficients, as is usually done for organic chemicals (TGD, 1996).

Modelling skin permeability with micellar liquid chromatography - University of Huddersfield RepositoryModelling skin permeability with micellar liquid chromatography - University of Huddersfield Repository
This study evaluates the potential application of micellar liquid chromatography (MLC) to predict skin permeation with a series of model compounds. MLC has previously been found to be useful in the prediction of partition coefficient values (logP) for pharmaceutical compounds, yet has not been incorporated in skin permeability models prior to this work. This article provides statistically supported data that this technique enhances the ability to predict the permeability of similar drugs through the skin (Kp). The replacement of a traditional physicochemical parameter, namely the octanol-water partition coefficient (logPow) with a chromatographically determined value (logPmw), results in a quantitative partition-permeability relationship that is robust to variation. MLC offers many benefits compared with the traditional techniques employed to obtain logP values.. ...

A poster (P165) presented at ASMS 2017, Indianapolis, discusses three sample preparation methodologies for 52 drug analytes, and presents evaluations of recovery, matrix effects and process efficiency. While dilute and shoot methods are easy and affordable, they can result in shortened LC column lifetimes and increased MS instrumentation downtime. Matrix effects can also effect sensitivity and overall method performance. Supported Liquid extraction (SLE) and Solid Phase Extraction (SPE) provide cleaner samples for LC-MS/MS and more robust clinical assays.. Successful sample preparation method development requires understanding the retention mechanism of the analytes in the assay. The octanol-water partition coefficient (logP) and acid dissociation constant (pKa) of the compounds of interest are important properties that can guide sample preparation strategy and optimization of method conditions..

Crystal structure of the channel-forming polypeptide antiamoebin in a membrane-mimetic environment. - Semantic ScholarCrystal structure of the channel-forming polypeptide antiamoebin in a membrane-mimetic environment. - Semantic Scholar
Crystals of an ion-channel-forming peptaibol peptide in a partial membrane environment have been obtained by cocrystallizing antiamoebin with n-octanol. The antiamoebin molecule has a bent helical conformation very similar to that established for Leu-zervamicin, despite a significantly different sequence for residues 1-8. The bent helices assemble to form a polar channel in the shape of an hour glass that is quite comparable to that of Leu-zervamicin. The molecules of cocrystallized octanol are found in two different areas with respect to the assembly of peptide molecules. One octanol molecule mimics a membrane segment along the hydrophobic exterior of the channel assembly. The other octanol molecules fill the channel in such a way that their OH termini satisfy the C==O moieties directed into the interior of the channel.

The researchers say if this were to be scaled up for industrial systems the engineered bacteria would produce the non-toxic derivative of 1-octanol, which would then be recovered and chemically transformed back into 1-octanol, ready for use.. The team found that their system produced 1-octanol without affecting the growth of the bacteria. They also found the system produced more 1-octanol than a system without the derivatization step, which they think is related to the fact that the derivative is not only less toxic but also more soluble in the surrounding water or solvent.. Dr. Jones said: A more soluble chemical may move away from the cells quicker, where its less likely to interfere with any of the bacterias processes.. Now the team has shown the concept of creating derivatives using programmed microorganisms, they want to set up a complete system, from production of the derivative to recovery of the desired chemical..

Let us now consider the transfer of amino acids from water to a bilayer membrane. According to the calculations of MacCallum et al. (2007), transfer from bulk water to the membrane interior correlates well with the water/cyclohexane scale. In contrast, the transfer of free energy from bulk water to the membrane interface correlates very well with the water/octanol scale. This is the result one would expect a priori. Indeed, it was noted previously that the partitioning of short peptide, designed to occupy the membrane-solution interface, correlates well with the water/octanol scale (Wimley and White, 1996; Wimley et al., 1996). In summary, the water/octanol thermodynamic scale does not reflect the partitioning of amino acids in the interior of membranes but to the membrane-solution interface. Finally, let us consider an even more complex situation, the insertion of transmembrane helices using the translocon expression system. The fascinating measurements of Hessa et al. (2005a) are suggestive of ...

The aromatization of 2-octanol derived from castor oil as a byproduct in the formation of sebacic acid was investigated on various zeolite catalysts. Zn ion-exchanged MFI (ZSM-5) zeolites with small silica/alumina ratios and zinc contents of 0.5 to 2.0 wt. % were determined to exhibit good and stable activity for the reaction at 623 to 823 K. The yield of aromatics was 62% at 773 K and the space velocity 350 to 1400 h−1. The temperature and contact time dependences of the product distributions indicated the reaction pathways of 2-octanol→dehydration to 2-octene→decomposition to C5 and C3 compounds→further decomposition to small alkanes and alkenes→aromatization with dehydrogenation. Alcohols with carbon numbers of 5 to 8 exhibited similar distributions of products compared to 2-octanol, while corresponding carbonyl compounds demonstrated different reactivity.

Pseudomonas putida Idaho utilizes toluene, m-xylene, p-xylene, 1,2,4-trimethylbenzene, and 3-ethyltoluene as growth substrates when these hydrocarbons are provided in a two-phase system at 5 to 50% (vol/vol). Growth also occurs on Luria-Bertani medium in the presence of a wide range of organic solvents. The ability of the organism to grow in the presence of organic solvents is correlated with the logarithm of the octanol-water partition coefficient, with dimethyl-phthalate (log P(OCT) = 2.3) being the most polar solvent tolerated. During growth with p-xylene (20% [vol/vol]), there was an initial lag period accompanied by cell death, which was followed by a period of exponential growth. The stationary phase of growth was characterized by a dramatic decrease in cell viability, although cell dry weight and turbidity measurements slowly increased. Electron micrographs revealed that during growth in the presence of p-xylene, the outer cell membrane becomes convoluted and membrane fragments are shed ...

The experimental Rm values for a series of aminoalkanethiosulfuric acids, mercaptoalkanamines and aminoalkyl disulfides were determined by reverse phase thin layer chromatography. The Rm values were determined for various concentrations of methanol: water and the correlation obtained was extrapolated to 100% water. These values permitted the calculation of the log P values for each substance. The log P values obtained by this method were compared with those obtained using the shake-flask method and by theoretical calculations utilizing fragment constants.

i) LIPOPHILICITY (e.g., LogD and cLogP). Historically, lipophilicity was the first of the structural properties to be recognized as important for CNS penetration. As early as 1897, Overton observed correlations between oil-water partition coefficients and narcotic potencies of a series of compounds in tadpoles [4]. By the 1960s, Hansch introduced the octanol/water system, which became the standard for measuring partition coefficients, and he demonstrated that blood-brain barrier permeation is optimal when the LogP values are in the range of 1.5-2.7, with the mean value of 2.1. In line with Hanschs findings, the mean value for cLogP for 74 marketed CNS drugs has been reported by Leeson to be 2.5. A number of different guidelines for predicting BBB permeation based on structural properties have been proposed, which suggests preferred ranges for LogP of between 1 and 5 (Table 1). In addition to permeability, lipophilicity plays an important role in other pharmacokinetic properties that may affect ...

Partition coefficients - logP, and its pH-dependent pair, logD - are crucial in estimating the distribution of drugs in the human body. Drugs with higher partition coefficients modelled in an octanol/water system are more likely to be distributed in the hydrophobic tissues like blood. However, molecules with low partition coefficients can mostly be found in lipophilic areas of the human body, like lipid bilayers of cells. The quality of the logP/logD prediction can be enhanced by incorporating measured logP/logD data through training ...

Modern biofuels offer the potential to decrease engine out emissions while at the same time contributing to a reduction of greenhouse gases produced from individual mobility. In order to deeply investigate and improve the complete path from biofuel production to combustion, in 2007 the cluster of excellence Tailor-Made Fuels from Biomass was installed at RWTH Aachen University. Since then, a whole variety of possible fuel candidates have been identified and investigated. In particular oxygenated fuels (e.g. alcohols, furans) have proven to be beneficial regarding the particulate matter (PM)/ NOx trade-off [1, 2, 3] in diesel-type combustion. Alcohols that provide a longer ignition delay than diesel might behave even better with regard to this trade-off due to higher homogenization of the mixture. Recent studies carried out within the Cluster of Excellence have discovered new pathways to derive 1-octanol from biomass [4], which features a derived cetane number (DCN) of 39 ...
