Effect of arbuscular mycorrhizal fungi inoculation on root traits and root volatile organic compound emissions of Sorghum bicolor

Volatile organic compounds (VOCs) emitted by plant roots have important functions that can influence the rhizospheric environment. The aim of this study was to examine the effects of arbuscular mycorrhizal (AM) fungi on the profile of root VOCs. Sorghum (Sorghum bicolor) plants were grown in pots inoculated with either Glomus mosseae or Glomus intraradices, which formed mycorrhiza with the roots. Control plants were grown in pots inoculated with sterile inoculum and did not form mycorrhiza. Forty-four VOCs were determined using headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). Alkanes were the most abundant type of VOCs emitted by both mycorrhizal and non-mycorrhizal plants. Both the quantity and type of volatiles were dramatically altered by the presence of AM fungi, and these changes had species specificity. Compared with non-mycorrhizal plants, mycorrhizal plants emitted more alcohols, alkenes, ethers and acids but fewer linear-alkanes. The AM fungi also influenced the morphological traits of the host roots. The total root length and specific root length of mycorrhizal plants were significantly greater than those of non-mycorrhizal plants; however, both the incidence and length of root-hair were dramatically decreased. Our findings confirm that AM fungi can alter the profile of VOCs emitted by roots as well as the root morphology of sorghum plants, indicating that AM fungi have the potential to help plants adapt to and alter soil environments.

Synthesis and application of stable nitroxide free radicals fused with carbocycles and heterocycles

Stable nitroxide free radicals have traditionally been associated with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) or its 4-substituted derivatives as relatively inexpensive and readily accessible compounds with limited possibilities for further chemical modification. Over the past two decades, there has been a resurgence of interest in stable free radicals with proper functionalization tuned for various applications. The objective of this review is to present recent results with synthetic methodologies to achieve stable nitroxide free radicals fused with aromatic carbocycles and heterocycles. There are two main approaches for accessing stable nitroxide free radicals fused with arenes, e.g., isoin-doline-like nitroxides: further functionalization and oxidation of phthalimide or inventive functionalization of pyrroline nitroxide key compounds. The latter also offers the con-structions of versatile heterocyclic scaffolds (furan, pyrrole, thiophene, 1,2-thiazole, selenophene, pyrazole, pyrimidine, pyridine, pyridazine, 1,5-benzothiazepine) that are fused with pyrroline or tetrahydropyridine nitroxide rings. The possible applications of these new stable nitroxide free radicals, such as covalent spin labels and noncovalent spin probes of proteins and nucleic acids, profluorescent probes, building blocks for construction of dual active drugs and electroactive materials, and substances for controlled free radical polymerization, are discussed.

The effect of intermolecular forces on the glass transition of solute-polymer blends: 2. Extension to different solutes

The effects of intermolecular forces on the glass transition temperature (Tg) of various dye solutes in numerous polymer matrices have been investigated. The Tgs of these dye-polymer blends were found to depend on the polymer Tg, the dye Tg, their relative concentrations and the dye-polymer affinity. Attempts have been made to correlate increases in Tg with dye-polymer affinity using solubility parameters as a predictive tool. Poor correlations were obtained using global solubility parameters. Excellent correlations were made between elevation in Tg and enhanced dye-polymer affinity using averaged polar/hydrogen bonding solubility parameters. For all dye solutes, the Tg was low when there was a large mismatch in solubility parameters, increased as dye and polymer became more compatible and was at a maximum when the solubility parameters of both components were equal. The results also indicate that longer range polar and hydrogen bonding forces have a controlling influence on Tg.

Effect of power level on the microwave pyrolysis of tire powder

The pyrolytic performance of tire powder treated under different specific microwave powers (SMP), powers per 1?g sample, (9, 15, and 24?W/g) was investigated. The experimental results show that the pyrolysis level of tire powder was enhanced with increasing SMP. The maximum yields of liquid product (45%) and gas product (18.5%) were obtained at 15 and 24?W/g, respectively. In addition, the conversion rates of main organic elements transferred to three-phase products were calculated. All of the evolved gases were collected in successive gasbags, and 80% of the volumes were low-molecular-weight gases like H2, CH4 and C2H4; the fraction of gases generated increased with increasing SMP. The liquid products contained a large amount of aromatic hydrocarbons, and more limonene (nearly 10%) was produced in microwave pyrolysis than in conventional pyrolysis of tires. The proximate and ultimate analyses of the solid product showed a slight difference in composition as a function of SMP. Furthermore, there may be a competitive reaction between the sulfur release to the volatiles and sulfur fixation, forming ZnS; the amount of ZnS varied with SMP. The energy recovery was examined, which provides a useful measure of the energy efficiency of microwave pyrolysis process.

Characterization of Matrix-Isolated Antiaromatic Three-Membered Heterocycles. Preparation of the Elusive Thiirene Molecule

The preparation and characterization of thiirene (4), a heterocyclic analogue of cyclobutadiene (1), which is derived from the photolysis of 1,2,3-thiadiazole (5), is described.The methodology exploits the C2v symmetry of the species 4 and utilizes isotopic labeling to aid in the characterization and narrow band-pass filters to protect thiirene from reaction with light of lambda > 2700 Angstroem, when it is generated photochemically.The evidence for 4 is based on (1) the fact that the same monolabeled species <13C>X is formed from distinctly labeled <13C>-1,2,3-thiadiazoles, (2) the photoisomerization of labeled X to ethynyl mercaptan and thioketene both with randomized label, and (3) the likelihood that the observed infrared bands attributed to 4 belong to a single species possessing cyclopropenoid character.In addition to thiirene, ethynyl mercaptan (14) and thioketene (15) are derived from 5.There are thus two paths (lambda > 2900 Angstroem) originating from 5 which give rise to 14 and 15.One stems from thiadiazole without the intervention of 4 and does not scramble hydrogens or carbons; the other is mediated by thiirene, which necessarily makes the C-H bonds equivalent.Irradiation (lambda ca. 3500 Angstroem) of doubly labeled <2H,13C> thiirene gives all four possible ethynyl mercaptans, indicating at least one exchange of hydrogens between carbon atoms must occur.The most reasonable explanation for this exchange presumes that both hydrogens reside on a single carbon atom at some point during the photoisomerization of thiirene to ethynyl mercaptan (14).

Heterocyclic scaffolds for the treatment of Alzheimer?s disease

Background: The treatment and diagnosis of Alzheimer?s Disease (AD) are two of the most urgent goals for research around the world. The cognitive decline is generally associated with the elevated levels of extracellular senile plaques, intracellular neurofibrillary tangles (NFTs), and with a progressive shutdown of the cholinergic basal forebrain neurons transmission. Even if several key targets are under fervent investigation in the cure of AD, till now, the only approved therapeutic strategy is the treatment of symptoms by using cholinesterases inhibitors. It has been demonstrated that both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes are not only responsible of acetylcholine levels, but also play an pivotal role in A[1]-aggregation during the early stages of senile plaque formation. On the other hand the difficult management of AD is also related to effective diagnostic methods and efficient assays for the study of pathological features. In such complex a wide framework, heterocyclic molecules are essential backbone to build new and selective drugs as well as diagnostic probes. Methods: The goal of this review is to examine a selected sample of relevant applications of five- and six-membered heterocycles in AD’s therapeutic approaches. Results: Concerning the research on AD, the contribution of heterocyclic compounds is huge and here we report some representative examples. The review is organized in two main sections focused on five and six-membered heterocycles. The analyzed cases have been classified on the base of the structural features of molecules, taking into account the progressive increase in heteroatoms number. Conclusion: The discovery of an effective therapy or a diagnostic protocol for AD is still far, but consistent improvements are underway and contribution of heterocyclic compounds will be consistent and hopefully determinant.
