Book SynopsisThe opening chapter proposes that the use of accessible N-alkyl-2-haloaldimines Me2C(Hlg)CH=NR1 (Hlg = Cl (1), Br (2)) in the imine version of the Pudovik reaction with acidic esters of phosphorus acids vastly extends its synthetic potential due to the fact that a primary addition or protonation product, having mobile single halogen atoms, can undergo spontaneous transformations as well as transformations involving other reagents. The authors go on to maintain that speedy detection and isolation of various lectin types is required for diagnosis and therapeutics, thus resulting in the development of an effective method of preparation of lectin specific nanogold (silver)-labeled colloidal, and cross-linked neoglycoconjugates, based on maleic anhydride copolymers. The authors go on to discuss the various methods available for the splitting of racemates into separate enantiomers, based mainly on stereoselective chromatographic analysis (HPLC, GC, CE, TLC, etc.) or on the classical method of separating the enantiomers by crystallization of their diastereomeric salts. Another chapter examines the biomimetic sol-gel synthesis of silicon-chitosan-containing glycerohydrogels with the use of silicon tetraglycerolate (precursor) and chitosan salts (templates), namely, chitosan acetate, lactate, ascorbate, hydrochloride, hydrochloride-ascorbate and hydrochloride-glycolate, as well as examining the effect of the concentrations of the precursor, chitosan salt and a low-molecular-weight accelerator, estimating the pH of the medium and temperature (480C) of the sol-gel process on the gelation duration in multicomponent chitosan-containing systems. The authors propose an economically efficient and ecologically friendly means of plasmid DNA metallization, with the potential for the obtained plasmid to be investigated for vaccine adjuvant and antitumor agent properties. This volume also discusses the establishment of a linear regression, taking into account the errors in measurement of an explanatory (independent) variable. The authors suggest that the use of an error-independent instrumental variable correlated with the explanatory variable and inverse least-squares-based are two means for arriving at consistent parameter estimates.

Book SynopsisIn this book, authors present research on filamentous fungi and the way they impact and transform their microenvironment, thereby contributing to mobilization or immobilization of potentially toxic metals and metalloids. Additionally, the significant impact of filamentous fungi on the deployment of potentially toxic elements in soils and sediments with possible intracellular or extracellular transformation is also discussed. Following this, the authors present an overview of the various potential applications of fullerenes, including: anti HIV- protease activity, photodynamic DNA cleavage, free radical scavenger, antimicrobial action, fullerene-based photoelectric materials, catalytic properties of transition metal-fullerene complexes, and more. Next, an additional overview is presented on furfural production in the world, the characteristics of this compound as a platform product, and the methods applied for its production from different raw materials. The authors go on to analyze all of the designs and concepts made to date to pursue the best association motif and discuss all issues linked to this anticipated entropically adverse event. A study is presented on the effects of exposure of typical proteins to low frequency electromagnetic fields and to microwaves, wherein it was shown that exposure to electromagnetic fields induces unfolding of proteins, causing transitions from α-helix to β-sheet structures that may be responsible of aggregation phenomena, leading to neurotoxic and neurodegenerative disorders that can be considered as the first step toward certain pathologies. Later, the authors propose a treatment for red or brown sorghum which reduces the coloration, prepares the sorghum grain, improves the properties of the milling, increases the yield, and retains antioxidants in the flour. An additional study is presented on the electrical transport properties (electrical resistivity, thermal conductivity, and thermoelectric power) of five liquid alkali elements (Li, Na, K, Rb, and Cs) using the theory of pseudopotential. Ending the book, the authors discuss the mechanism of Li3PS4 formation in ethyl propionate, an organic solvent. In addition, a solvent selection guide is determined and presented

Book SynopsisThis collection presents recent results related to the synthesis, modification and characterization of triphenylamine oligomers and polymers by electrochemical methods, in particular Cyclic Voltammetry (CV). The modification by electrochemical methods of oligomers containing TPA as pendants groups, generating electroactive cross-linked networks accompanied by colour changes with high coloration efficiency is also discussed. Next, the authors review the mechanisms of formation and structure of FAEEs to their use as alcohol biomarkers, focusing on the developed analysis methods, fields of application and published articles. A critical overview is also provided on the methodological challenges and considerations for their analysis, the present limitations and advantages relatively to other alcohol biomarkers, and challenges and directions in the research of FAEEs as alcohol biomarkers. Afterwards, liquorice is discussed, specifically how liquorice roots have been object of many studies dealing with their biological activities as well as their phytochemical profiles, however the aerial parts of this plant, and in particular the leaves, have received scarce attention and been considered a waste product. Continuing, over seventy dimeric Pt(II) complexes which contain at least one thio-ligand are analyzed. Thio-ligands are very useful as soft-S donor ligands in the chemistry of platinum. Another review correlates the structural parameters of about ninety mononuclear Pt(II) complexes containing at least one seleno- or silyl- ligand. Each of these Pt(II) complex has structure with square planar geometry with various degrees of distortion. The authors argue, in a separate and final review, that carnitine and its derivatives are available from meat and synthesized by the body e.g. in vegetarians, so that an occasional pharmacological suppression of their levels doesnt translate to cardiovascular disease prevention. The problem should be seen within the scope of placebo marketing under the guise of evidence-based medications.

Book SynopsisAdvances in Chemistry Research. Volume 46 opens with a summary of the authors recent findings in which an integrated computational approach to in silico drug design was used to identify novel HIV-1 entry inhibitor scaffolds mimicking high-affinity ligands of the viral envelope proteins, namely broadly neutralizing anti-HIV-1 antibodies (bNabs) VRC01, 3074, 10E8, and primary receptor CD4. Additionally, the authors examine recently published sequence- and structure-based methods for predicting peptide binders to major histocompatibility complex molecules and discuss their advantages and limitations (MHC). MHC molecules present peptide fragments (antigens) derived from pathogens and display them at the cell surface for T-cell recognition. Fluid Catalytic Cracking (FCC) is one of the most important technologiesapplied in many refineries and has the ability to convert anextensive range of feedstocks to more valuable products including gasoline and propylene. This book provides a general background of the FCC process and details of the process will be presented focusing on FCC catalyst materials and additives. The effects of external physical fields (thermal (TF), ultrasonic (UF), and microwave (MF)) on the isothermal kinetics of fullerol formation are investigated. A spectrophotometric method was developed to monitor the conversion degree of fullerene to fullerol, and both the isothermal kinetic curves and conversion curves for fullerol formation are determined under TF, UF, and MF fields at different temperatures ranging from 293 to 313 K. The authors examine the way an excess of oxidative species can cause fatal damage to lipids within the cell membranes, cellular proteins and nucleic acids, as well as to the constituents of the extracellular matrix, such as collagens and proteoglycans. A simple expression is derived to evaluate diffusion activation energy, which involves only processing temperatures and the number of waveguide modes supported by the formed structures. Neither data processing nor special software is necessary for this calculation, and the technique also enables the evaluation of the diffusion activation energy directly in the procedure of self-similarity verification using the refractive index profiles found from the measured waveguide mode spectra. Lastly, this book suggests that thermal fluctuations play an important role in aid of flow stress above the temperature of 0 K, and the aid energy supplied by the thermal fluctuations is given for NaCl single crystals doped with various monovalent ions separately, when the weak obstacle (i.e. dopant ion) is overcome by a dislocation.

Book SynopsisIn the introductory chapter of Advances in Chemistry Research. Volume 47, the authors review eterogeneous catalytic systems reported from 2004 to 2018 for some of the key chemical transformations of limonene such as oxidation, hydrogenation and isomerization reactions. The main advantages of the heterogeneous catalytic processes are the easy separation of a catalyst from a reaction mixture, the possibility of reuse and the mild reaction conditions of the processes. The processes responsible for the memory effect (induced by electrical breakdown and discharge in custom-made/commercial tubes) filled with noble gases at low pressure are analyzed in the next chapter. This analysis is based on the experimental results pertaining to a mean value of electrical breakdown time delay as a function of the afterglow period. Next, a variety of hydroxyquinoline-based compounds from three perspectives, namely their applications as anticancer agents, as sensing agents for metal detection, and the mechanisms of their actions. The authors provide an overview on the ruthenium(II) polypyridyl complexes catalyzed and visible-light assisted procedures employed for the production of radical intermediates from sulfonyl chlorides. In addition, they account the applications of these radical species in the syntheses of functionalized aliphatic and aromatic compounds. Because previous kinetic models assume that the reaction medium was reacting at random and without a turnover associated to thermodynamics exchanges, some included experimental studies aim to show that coupling factor 1 from spinach chloroplasts has latent ATPase activity which becomes expressed after heat-treatment and incubation with calcium. Lastly, optically active ketones are isolated from the domino deprotection/decarboxylation/protonation reaction of racemic allyl or benzyl B-ketoesters and corresponding enol carbonates mediated with both palladium species and unichiral aminoalcohols. Protonation of an ammonium enolate as the key enantioselective step is consistent with the absence of a relationship between the nature of the substrate and the absolute configuration of the isolated ketone.

A recent structural analysis of oligomannose glycans, based on biophysical methods (including solution nuclear magnetic resonance and X-ray crystallographic analyses) are presented and discussed. A summary of the history, clinical uses, and pharmacokinetics of polyethylene glycol interferon are presented. Important features regarding its clinical efficacy in combination with new antiviral agents like ribavirin, telaprevir, entecavir, tenofovir, adefovir, sofosbuvir and ledipasvir are also discussed. The fluorescence properties of anthracene based ligands are proposed to be suitable to design sensors for cations as well as anions. Some of the complexes of anthracene-based ligands are reported to have potential for light-emitting devices. Various quantum chemical properties, dipole moments, bond lengths, charges, total electronic energies, the highest occupied and lowest unoccupied molecular orbital energies and the interfrontier molecular orbital energy gap values are obtained and compared. An empirical equation is derived for calculating the free formaldehyde concentration in alcohol-formaldehyde systems at various temperatures and total formaldehyde concentrations, as well as an equation for evaluating solvent concentrations. In the final study, the authors exploit the intense fluorescence behavior of luminol for a quantitative understanding of hydrogen bonding behavior and its interaction with several biological media, with the help of steady state and time-resolved measurements as well as density functional theory calculations.Table of ContentsFor more information, please visit our website at:https://novapublishers.com/shop/advances-in-chemistry-research-volume-54/

Book SynopsisAdvances in Chemistry Research. Volume 57 begins with a focus on structures which core-modified porphyrins and derivatives adopt, as well as a comparison of electronic properties, including aromaticity, of core-modified porphyrins and common tetrapyrroles. Perspectives of studies and applications of core-modified tetrapyrroles are considered as well. Following this, the authors provide a brief introduction to solvation processes in pure solvents, followed by an extension of the topic to mixtures, and a thorough analysis of preferential solvation phenomena. In one study, Rhodobacter sphaeroides cytochrome c oxidase is prepared, in which n terminal histidines 3, 7, and 10 of subunit III have been replaced with glutamine residues and enzymatic activities of the isolated mutant enzyme assessed. Different aspects of the problem of the oxo-atom transfer of organometallic complexes in oxidation reactions of some organic compounds with dioxygen, under UV-irradiation, are discussed. Examples demonstrating the catalytic properties of dioxo-Mo-complexes in oxidation of the chlorinated derivatives of mono- and biphenyl substituted alkanes are presented. The authors also examine plant biomass-based substrates or waste coproducts that have been examined to determine whether they could support pullulan synthesis by the fungus A. pullulans, and identify which show the most promise for commercial pullulan production. In conclusion, clustering in aqueous solutions of H2CO3 and NaHCO3 in the mass range from 100 to 200 thousand Dalton is studied by way of gravitational mass spectroscopy. The formation of ensembles of clusters obeying the first and second Zubov equation was found.

Book SynopsisAdvances in Chemistry Research. Volume 58 first characterizes electrochemical oxidation processes from an ecotoxicological perspective. This approach allows for the evaluation of the influence of electrochemical degradation parameters, such as electrode material or type of electrolyte, in the modulation of toxicity under different scenarios. Following this, the authors present a collection of existing knowledge on electro-fenton and anodic oxidation electrochemical processes. The choice of electrode materials plays an important role in both processes for better efficiency. A standardized procedure is proposed for analyzing humic samples of various genesis consisting of four successive methods of analysis. The results obtained in this case present a set of, semi-quantitative and quantitative parameters in the macromolecule of carboxyl, aromatic, polysaccharide and aliphatic fragments. A highly effective adsorbent for p-chlorophenol is been synthesized using magnetite nanoparticles coated with humic acids. The adsorbent is synthesized via co-precipitation of a mixed Fe3+ and Fe2+ solution using NH4OH 25% at pH 11 followed by the rapid addition of humic acids solution in NaOH 1 M. This collection also reviews the spectral and luminescent properties of humic acids, as well as identifies the impact of humic acids on the effectiveness of organic compounds photodegradation. In the concluding study, the water quench test is applied as an experimental method for thermal shock resistance testing, and the authors provide a morphological analysis of the samples before and during the testing.
