Synthesis of ring-opened derivatives of triazole-containing quinolinones and their antidepressant and anticonvulsant activities

Based on the potent antidepressant and anticonvulsant activities of the triazole-containing quinolinones reported in our previous work, a series of ring-opened derivatives of them were designed, synthesized in this work. Their antidepressant and anticonvulsant activities were screened using the forced swimming test (FST) and the maximal electroshock seizure test (MES), respectively. The results showed that compounds 4a, 5a, 6c-6e, 6g-6i, and 7 led to significant reductions in the accumulated immobility time in the FST at a dose of 50 mg/kg. Especially compound 7 exhibited higher levels of efficacy than the reference standard fluoxetine in the FST and the tail suspension test. The results of an open field test excluded the possibility of central nervous stimulation of 7, which further confirmed its antidepressant effect. Meanwhile, compounds 6a-6i and 7 showed different degrees of anticonvulsant activity in mice at the doses range from 300 to 30 mg/kg in the MES. Among them, compounds 6e and 7 displayed the ED50 of 38.5 and 32.7 mg/kg in the MES, and TD50 of 254.6 and 245.5 mg/kg, respectively. No one showed neurotoxicity at the dose of 100 mg/kg. The preliminary investigation forward to their mechanism indicated that regulation of GABAergic system might contribute to their anticonvulsive and anti-depressive action.

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.

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.

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.

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.

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.

Slow Magnetic Relaxation in a [Na2Dy4] Complex and Coexistence of Multiple Metal Rings

Three rare isostructural heterometallic complexes [Na-2{Ln(4)(mu(3)-OH)(2)(ppt)(4)(Hppt)(2)(OAc)(2)}(DMF)(4)] . xH(2)O (H(2)ppt=3-(2-hydroxyphenyl)-5-(pyrazin-2-yl)-1,2,4-triazole, x=2.5, Ln=Dy (1); x=2, Ln=Er (2); x=0, Ln=Yb (3)) have been obtained. The structural analysis displayed that two Na-I and four Ln(III) ions were linked together through N-N groups and O atoms to form a metallmacrocycle with the connectivity pattern [Dy-O-Na-N-N-Dy-O](2). Such cases possess rare hexametallic ring, which further displays one tetrametallic and two trimetallic cyclic units. Magnetic measurements reveal single-molecule magnet (SMM) behavior for 1 with the effective energy barrier of 51.6 K and pre-exponential factor of 6.16×10(-6) s deduced from frequency-dependent magnetic susceptibilities. Ab initio calculations prove that the weak ferromagnetic coupling mainly originats from the dipolar interaction. The transversal magnetic moments in the ground Kramers could suppressed the quantum tunneling of magnetization.
