Mechanisms by which fungicides increase grain sink capacity and yield of spring barley when visible disease severity is low or absent

Fungicides are a central component of disease management programmes in many cereal production systems worldwide, but intensive use has led to problems with the evolution of resistance in pathogen populations, harmful effects on non-target organisms and residues in the food chain and environment. Better targeting of fungicide applications, according to the likely response of the crop, would help improve the sustainability of disease management, but decision making is hindered by our poor understanding of the mechanisms by which fungicides influence crop yield. This study investigated possible mechanisms responsible for yield increases following fungicide treatment of spring barley with little or no visible disease. Field experiments conducted over six site-years in the UK quantified the effects of the protectant fungicide chlorothalonil (Chl), and systemic fungicides prothioconazole (Pro) and pyraclostrobin (Pyr), applied on their own or in combination. The severity of visible disease in the absence of fungicide treatments was minimised by growing varieties with good disease resistance. Contrasting fungicide chemistries led to different effects on yield. There were two components to the yield increases. The first involved an increase (4.3-7.5 %) in grain number m(-2) and was elicited by Pro and Pyr, but not Chl. The second was a smaller increase (3.7-4.6%) in mean grain weight (MGW) and was elicited by each of the fungicides tested. The effect of the triazole (Pro) and strobilurin (Pyr) on grain number was not the result of the control of visible disease pre-anthesis or an increase in photosynthetically active radiation (PAR) interception. Nor was it the result of the control of asymptomatic pathogen infection or possibly leaf surface saprophytes, because Chl gave equivalent control without increasing grain number. Our results are consistent with the hypothesis that triazoles and strobilurins can increase grain sink capacity through direct physiological effects in the field. These apparent physiological effects differ from those reported for wheat as they occur pre-anthesis and are not associated with delayed leaf senescence and resulting increased PAR interception. Application of Pro + Pyr increased radiation use efficiency (RUE), estimated over the whole season, by around 10 % compared to untreated controls and 6 % compared to Chl treated crops. Evidence is presented to show that whilst the average yield response to Pro + Pyr in the absence of disease was around 3 %, the response varied widely between sites and years. Where effects on grain number do occur, they can be elicited in a range of varieties by a single application made at booting. We argue that benefiting from physiological effects of triazole and strobilurin fungicides on spring barley yield, through appropriate timing of application, is compatible with strategies to target and reduce fungicide use in this crop.

Identifying and explaining the regioselectivity of alkylation of 1,2,4-triazole-3-thiones using NMR, GIAO and DFT methods

The regioselectivity of the alkylation of four 1,2,4-triazole-3-thiones with eight different organic halides was determined by the comparison of experimentally observed NMR chemical shifts of the product molecules to those predicted by density functional theory (DFT) calculations via gage independent atomic orbital (GIAO) method. The combination of the employed reactants resulted in ten different model alkylated triazoles, seven of which are new and not previously described. The reaction was performed in neutral and alkaline medium with the observation that S-alkylation occurs selectively and with slightly lower yields under neutral conditions. Highest occupied molecular orbitals, electron localization function, electrophilic Fukui function, and different types of partial charges were considered as reactivity descriptors to reveal the observed regioselectivity and to explain the structure of synthesized products. In conclusion, the comparison of the chemical shifts of H-1 and C-13 NMR of the alpha-methylene group of the products with those calculated by incorporating the GIAO DFT-computed isotropic chemical shielding gives an approach for the correct and reliable determination of the site of alkylation as the S-atom of the synthesized S-alkylated 1,2,4-triazoles.

Synthesis of biologically important 4-Phenyl-C-glycosyl-1,2,3-triazole derivatives by Cu(I)-catalyzed azide-alkyne cycloaddition

A new series of 4-phenyl-C-glycosyl-1,2,3-triazoles were synthesized using Cu(I)- catalyzed azide-alkyne cycloaddition. The key step in the synthesis involved the coupling of unprotected glycosyl azides with substituted C-glycosylated phenyl acetylenes. Using o-phenylenediamine as a ligand, we could significantly reduce the reaction time, improve the product yield, and simplify the purification process. Broad substrate scope in terms of sugars was achieved.

Diversification of quinoline-triazole scaffolds with CORMs: Synthesis, in vitro and in silico biological evaluation against Plasmodium falciparum

A discrete series of tricarbonyl manganese and rhenium complexes conjugated to a quinoline-triazole hybrid scaffold were synthesised and their inhibitory activities evaluated against Plasmodium falciparum. In general, the complexes show moderate activity with improved inhibitory activities for the photoactivatable manganese(I) tricarbonyl complexes in the malaria parasite. All complexes are active in the dark against the NF54 CQS (chloroquine-sensitive) and K1 MDR (multidrug-resistant) strains of Plasmodium falciparum, with IC50 values in the low micromolar range. Of significance, the complexes retain their activity in the MDR strain with resistance indices ranging between 1.1 and 2.1. The Mn(I) analogues display photodissociation of all three CO ligands upon irradiation at 365 nm. More importantly, the complexes show increased antimalarial activity in vitro upon photoactivation, something not observed by the clinically used reference drug, chloroquine. As a purported mechanism of action, the compounds were evaluated as beta-haematin inhibitors. To further understand the interactions of the complexes, in silico hemozoin docking simulations were performed, attesting to the fact that CO-release could be vital for blocking the hemozoin formation pathway. These results show that this strategy may be a valuable, novel route to design antimalarial agents with higher efficacy.

Dual-supramolecular contacts induce extreme Hofmann framework distortion and multi-stepped spin-crossover

An extended nitro-functionalised 1,2,4-triazole ligand has been used to induce considerable lattice distortion in a 2-D Hofmann framework material via competing supramolecular interactions. Single crystal X-ray diffraction analyses on [Fe-3(N-cintrz)(6)(Pd(CN)(4))(3)]center dot 6H(2)O (N-cintrz: (E)-3-(2-nitrophenyl)acrylaldehyde) reveal a substantial deviation from a regular Hofmann structure, in particular as the intra- and inter-layer contacts are dominated by hydrogen-bonding interactions rather than the typical pi-stacking arrays. Also, the 2-D Hofmann layers show an assortment of ligand conformations and local Fe-II coordination environments driven by the optimisation of competing supramolecular contacts. Temperature-dependent magnetic susceptibility measurements reveal a two-step spin crossover (SCO) transition. Variable temperature structural analyses show that the two crystallographically distinct Fe-II centres, which are arranged in stripes (2 : 1 ratio) within each Hofmann layer, undergo a cooperative HS <-> HS/LS <-> LS (HS = high spin, LS = low spin) transition without periodic spin-state ordering. The mismatch between crystallographic (2 : 1) and spin-state (1 : 1) periodicity at the HS : LS step provides key insight into the competition (frustration) between elastic interactions and crystallographically driven order.

Polarity-Tolerant Chloride Binding in Foldamer Capsules by Programmed Solvent-Exclusion

Persistent anion binding in a wide range of solution environments is a key challenge that continues to motivate and demand new strategies in synthetic receptor design. Though strong binding in low-polarity solvents has become routine, our ability to maintain high affinities in high-polarity solvents has not yet reached the standard set by nature. Anions are bound and transported regularly in aqueous environments by proteins that use secondary and tertiary structure to isolate anion binding sites from water. Inspired by this principle of solvent exclusion, we created a sequence-defined foldameric capsule whose global minimum conformation displays a helical folded state and is preorganized for 1:1 anion complexation. The high stability of the folded geometry and its ability to exclude solvent were supported by solid-state and solution phase studies. This capsule then withstood a 4-fold increase in solvent dielectric constant (epsilon(r)) from dichloromethane (9) to acetonitrile (36) while maintaining a high and solvent-independent affinity of 10(5) M-1; Delta G similar to 28 kJ mol(-1). This behavior is unusual. More typical of solvent-dependent behavior, Cl- affinities were seen to plummet in control compounds, such as aryl-triazole macrocycles and pentads, with their solvent-exposed binding cavities susceptible to dielectric screening. Finally, dimethyl sulfoxide denatures the foldamer by putative solvent binding, which then lowers the foldamer’s Cl- affinity to normal levels. The design of this capsule demonstrates a new prototype for the development of potent receptors that can operate in polar solvents and has the potential to help manage hydrophilic anions present in the hydrosphere and biosphere.

Axially chiral bis-1,2,3-Triazol-4-ylidene-Ag(I)-MIC and, bis-Au(I)-MIC complexes of (R)-BINOL and (-)-Menthol scaffold: Synthesis, structure, and characterizations

Herein, we report the novel axially chiral bis-Ag(I)-MIC and, bis-Au(I)-MIC complexes bearing axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) ligands were synthesized. The enantiopure R-BINOL was employed as a basic unit to synthesize a axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) ligands (1-2)a. In particular, the axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) ligands (1-2)a, were obtained from the reaction of corresponding bis-1,2,3-triazole ligand precursor with methyl and ethyl iodide in 82-90% yields. Novel axially chiral bis-Ag(I)-MIC complexes (1 – 2)b, were prepared by the treatment of corresponding axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) iodide salts, (1 – 2)a, with Ag2O via in-situ deprotonation method in 69-86% yields. Novel axially chiral bis-Au(I)-MIC complex-2c was synthesized from their respective novel axially chiral bis-Ag(I)-MIC complex-2b, using transmetallation reaction with (SMe2)AuCl in 70% yield. All these novel axially chiral bis-Ag(I)-MIC and bis-Au(I)-MIC complexes were isolated for the first time and structurally characterized by H-1 NMR and C-13{H-1)-NMR spectroscopy, FT-IR spectroscopy, mass spectrometry, elemental analysis, specific optical rotation and, single crystal X-ray crystallography.

Pesticide multi-residues in Dendrobium officinale Kimura et Migo: Method validation, residue levels and dietary exposure risk assessment

Dendrobium officinale Kimura et Migo (D. officinale) is a dual-use plant with both botanical medicine and food applications, drawing increasing attentions. Pesticides are inevitably applied on D. officinale in commercial artificial-sheltered cultivation, yet little is known about pesticide residue levels in D. officinale. A modified high through-put QuEChERS method coupled with HPLC-MS/MS was developed and validated to detect 76 pesticides in D. officinale. Graphitized multi-wall carbon nanotubes (g-MWCNTs) was selected as the clean-up sorbent, showing relative weak affinity to triazole fungicide having planar structure in their molecular and low matrix effects of pesticides in D. officinale samples compared to MWCNTs and pesticarb. The validated method was applied to analyze pesticide residues in 86 real D. officinale samples collected from three main producing provinces. 43 different pesticides were detected with highest residue of 6.11 mg/kg for dimethomorph. Given possible health risks related to pesticide residues, accordingly, risk assessment of human exposure to pesticides via intake of D. officinale was thus performed, indicating that the pesticide residue in fresh or dry D. officinale would not cause potential risk to human health either in the long-term or short-term. This work improved our understanding of potential exposure risk of pesticide multi-residues in D. officinale.

Synthesis and Biological Studies of O3-Aryl Galactosides as Galectin Inhibitors

beta-Galactose derivatives have recently been reported to selectively inhibit galectin-3, and a library of O3-arylated galactosides with varying substitution patterns was designed to study such inhibitions further. The O3-arylated galactosides were synthesized using diaryliodonium salts under mild and transition metal free conditions, providing the target products in moderate to good yields. An O3-trifluoroethylated galactoside was also synthesized using iodonium salt chemistry. Azido-substituted products were subsequently transformed into the corresponding triazoles. After deprotection, a selection of galactoside derivatives were evaluated for inhibitory potencies against galectins-1, 3, 4 N (N-terminal domain), 4 C (C-terminal domain), 7, 8 N, 8 C, 9 N, and 9 C and one compound with promising affinity and selectivity for both the N- and C-terminal domain of galectin-9 was discovered.

Synthesis of novel 1,2,3 triazole derivatives and assessment of their potential cholinesterases, glutathione S-transferase enzymes inhibitory properties: An in vitro and in silico study

In this study, new 1,2,3-triazole derivatives containing chalcone core (1-7) were synthesized. Obtained compounds were characterized by IR, H-1 NMR, C-13 NMR, and mass studies. Characterized compounds (1-7) inhibitory effects were tested against the glutathione S-transferase (GST), acetylcholinesterase (AChE), and Butyrylcholinesterase (BChE). Their K-i values were in the range of 5.88-11.13 mu M on AChE, 5.08-15.12 mu M on BChE, and 9.82-13.22 mu M on GST. Remarkable inhibitory effects were obtained against three tested metabolic enzymes. Also, binding scores of the best-inhibitors against AChE, BChE, and GST enzymes were detected as -9.969 kcal/mol, -10.672 kcal/mol, and -8.832 kcal/mol, respectively. Isoindoline-1,3-dione and benzothiophene moieties played a critical role in the inhibition of AChE and BChE enzymes, respectively. Phenylene and triazole moieties had the most important interactions for inhibition of the GST enzyme. Therefore, in vivo and in silico results indicated that these compounds can be considered in drug design processes for the treatment of some diseases including Alzheimer’s disease (AD), leukemia, and some type of cancer.
