Birds feeding on tebuconazole treated seeds have reduced breeding output

Drilled seeds are an important food resource for many farmland birds but may pose a serious risk when treated with pesticides. Most compounds currently used as seed treatment in the EU have low acute toxicity but may still affect birds in a sub-chronic or chronic way, especially considering that the sowing season lasts several weeks or months, resulting in a long exposure period for birds. Tebuconazole is a triazole fungicide widely used in agriculture but its toxicity to birds remains largely unknown. Our aim was to test if a realistic scenario of exposure to tebuconazole treated seeds affected the survival and subsequent reproduction of the red-legged partridge (Alectoris rufa). We fed captive partridges with wheat seeds treated with 0%, 20% or 100% of tebuconazole application rate during 25 days in late winter (i.e. tebuconazole dietary doses were approximately 0.2 and 1.1 mg/kg bw/day). We studied treatment effects on the physiology (i.e. body weight, biochemistry, immunology, oxidative stress, coloration) and reproduction of partridges. Exposed birds did not reduce food consumption but presented reduced plasmatic concentrations of lipids (triglycerides at both exposure doses, cholesterol at high dose) and proteins (high dose). The coloration of the eye ring was also reduced in the low dose group. Exposure ended 60 days before the first egg was laid, but still affected reproductive output: hatching rate was reduced by 23% and brood size was 1.5 times smaller in the high dose group compared with controls. No significant reproductive effects were found in the low dose group. Our results point to the need to study the potential endocrine disruption mechanism of this fungicide with lagged effects on reproduction. Risk assessments for tebuconazole use as seed treatment should be revised in light of these reported effects on bird reproduction. (C) 2020 Elsevier Ltd. All rights reserved.

An extensive research on aldose reductase inhibitory effects of new 4H-1,2,4-triazole derivatives

Aldose reductase (AR) is a key enzyme, which triggers the excessive accumulation of sorbitol in insulin independent tissues leading to severe diabetes-induced microvascular complications. Substantial evidence has proven that AR inhibition is a well-established strategy to attenuate these complications. In the current work, new 2-[(4-amino-5-aryl-4H-1,2,4-triazol-3-yl)thio]-N-(thiazol/benzothiazol-2-yl)acetamides (1-18) were synthesized and evaluated for their inhibitory capacities on AR. 2-[(4-Amino-5-(4-methylphenyl)-4H-1,2,4-triazol-3-yl)thio]-N-(5-nitrothiazol-2-yl)acetamide (12) and 2-[(4-amino-5-(3-pyridyl)-4H-1,2,4-triazol-3-yl)thio]-N-(6-nitrobenzothiazol-2-yl)acetamide (17) were identified as the most effective AR inhibitors in this series with the K-i values of 0.04 +/- 0.01 mu M and 0.08 +/- 0.02 mu M, respectively as compared to quercetin (K-i = 5.66 +/- 0.66 mu M). These two compounds displayed competitive AR inhibition. MTT assay, a tetrazolium-based cell viability assay, was performed to determine the cytotoxic effects of compounds 1-18 on L929 mouse fibroblast (healthy) cell line. Compounds 1-18, except for compounds 10, 13, 14, 15 and 16, were found nontoxic against healthy cells. Besides, molecular docking studies were fundamentally in agreement with the biological data with regard to essential pi-pi interactions with Trp219, Phe122 and Trp111 residues in the active site of AR. Eventually, in vitro and in silico assays ascertain that in particular compounds 12 and 17 will attract a great notice as drug-like AR inhibitors for further investigations related to amelioration of long-term diabetic complications.

Water Soluble Iron-Based Coordination Trimers as Synergistic Adjuvants for Pancreatic Cancer

Pancreatic cancer is a usually fatal disease that needs innovative therapeutic approaches since the current treatments are poorly effective. In this study, based on cell lines, triazole-based coordination trimers made with soluble Fe(II) in an aqueous media were explored for the first time as adjuvant agents for the treatment of this condition. These coordination complexes were effective at relatively high concentrations and led to an increase in reactive oxygen species (ROS) in two pancreatic cancer cell lines, PANC-1 and BXPC-3, and this effect was accompanied by a significant reduction in cell viability in the presence of gemcitabine (GEM). Importantly, the tested compounds enhanced the effect of GEM, an approved drug for pancreatic cancer, through apoptosis induction and downregulation of the mTOR pathway. Although further evaluation in animal-based models of pancreatic cancer is needed, these results open novel avenues for exploring these iron-based materials in biomedicine in general and in pancreatic cancer treatment.

Co(III), Rh(III) & Ir(III)-Catalyzed Direct C-H Alkylation/Alkenylation/Arylation with Carbene Precursors

Metal carbenes play a pivotal role in transition-metal-catalyzed synthetic transfer reactions. The metal carbene is generated either from a diazo compound through facile extrusion of N-2 with a metal catalyst or in situ generated from other sources like triazoles, pyriodotriazoles, sulfoxonium ylides and iodonium-ylide. On the other hand, Co(III), Rh(III) & Ir(III)-catalyzed C-H functionalizations have been well established as a key synthetic step to enable the construction of various synthetic transformations. Interestingly, in recent years, merging of these two concepts C-H activation and carbene migratory insertion gained much attention, in particular group 9 metal-catalyzed arene C-H functionalizations with carbene precursors via carbene migratory insertion. In this review, we summarize recent advances in Co(III), Rh(III) & Ir(III)-catalyzed direct C-H alkylation/alkenylation/arylation with carbene precursors and also discuss key synthetic intermediates within the catalytic cycles.

Flavonoid Glycosides with a Triazole Moiety for Marine Antifouling Applications: Synthesis and Biological Activity Evaluation

Over the last decades, antifouling coatings containing biocidal compounds as active ingredients were used to prevent biofouling, and eco-friendly alternatives are needed. Previous research from our group showed that polymethoxylated chalcones and glycosylated flavones obtained by synthesis displayed antifouling activity with low toxicity. In this work, ten new polymethoxylated flavones and chalcones were synthesized for the first time, including eight with a triazole moiety. Eight known flavones and chalcones were also synthesized and tested in order to construct a quantitative structure-activity relationship (QSAR) model for these compounds. Three different antifouling profiles were found: three compounds (1b, 11a and 11b) exhibited anti-settlement activity against a macrofouling species (Mytilus galloprovincialis), two compounds (6a and 6b) exhibited inhibitory activity against the biofilm-forming marine bacteria Roseobacter litoralis and one compound (7b) exhibited activity against both mussel larvae and microalgae Navicula sp. Hydrogen bonding acceptor ability of the molecule was the most significant descriptor contributing positively to the mussel larvae anti-settlement activity and, in fact, the triazolyl glycosylated chalcone 7b was the most potent compound against this species. The most promising compounds were not toxic to Artemia salina, highlighting the importance of pursuing the development of new synthetic antifouling agents as an ecofriendly and sustainable alternative for the marine industry.

Efficient synthesis and DFT analysis of novel 1,2,3-triazole-based dithiocarbamates

Novel 1,2,3-triazole-dithiocarbamate hybrids were synthesized in moderate to good yields (60-75%) in green solvent system H2O/t-BuOH by click azide-alkyne [3 + 2] cycloaddition reaction with avoiding isolation and handling of hazardous organic azides. The structure of the all products were unambiguously characterized by various techniques such as CHN, (HNMR)-H-1, (CNMR)-C-13, ESI-MS and FT-IR. The synthesis protocol proceeds under easy, green and mild reaction conditions with available inexpensive starting materials. The HOMO-LUMO analysis (electrophilicity index), H-1 and C-13 chemical shifts and Mulliken charge distribution of the characterized structure of 4a have been also calculated by applying B3LYP/6-31+G (d, p) level of density functional theory (DFT) method. The aim of the DFT study was to make a reasonable assignment of spectroscopic data. The DFT calculated data were found in close agreement to that of experimental data. (C) 2020 Elsevier B.V.

Embryonic exposure to prothioconazole induces oxidative stress and apoptosis in zebrafish (Danio rerio) early life stage

Triazole fungicides are extensively applied in general agriculture for fungal control and have negative impacts on aquatic organisms. Prothioconazole, a widely used triazole fungicide, is toxic to zebrafish, but systematic research on the negative effects caused by prothioconazole in zebrafish embryos is limited. In this study, we studied the developmental toxicology, oxidative stress and apoptosis caused by prothioconazole in zebrafish embryos. Exposure to 0.850 ma prothioconazole impacts embryo survival and hatching. Prothioconazole exposure caused embryo malformation, especially yolk-sac and pericardial edemas, and prothioconazole-induced apoptosis was observed. Additionally, exposure to a high prothioconazole concentration up-regulated the expression levels of oxidative stress defense-related genes and p53. The bax to bcl2 ratio increased along with exposure time and prothioconazole concentration. Prothioconazole induced apoptosis during the early life stages of zebrafish and may trigger oxidative-stress and p53-dependent pathway responses. Our findings increase our understanding of the molecular mechanisms of oxidative stress and cell death caused by prothioconazole. (C) 2020 Elsevier B.V. All rights reserved.

Copolymers of Methyl Acrylate and Vinylazoles: Synthesis, Thermolabile Properties, and Grafting of Polyamine Chains

New copolymers of methyl acrylate with 1-vinylimidazole, 1-vinyl-1,2,4-triazole, and 4-vinyl-1,2,3-triazole are synthesized by radical copolymerization. It is shown that the reactivity ratios for methyl acrylate and 1-vinylimidazole are 0.83 +/- 0.09 and 0.25 +/- 0.02, for methyl acrylate and 1-vinyl-1,2,4-triazole are 1.0 +/- 0.04 and 0.27 +/- 0.01, and for methyl acrylate and (4-vinyl-1H-1,2,3-triazolyl)-methyl pivalate are 0.56 +/- 0.03 and 2.90 +/- 0.20, respectively. The behavior of the copolymers in aqueous media and their thermoresponsive properties are studied by potentiometric titration and dynamic light scattering. Copolymer macromolecules occur in aqueous solutions in the form of large associates the fraction of which increases upon heating; in some cases, an insoluble phase is formed. It is found that the copolymers with the grafted oligopropylamine moieties containing N-vinylazole units can interact with the DNA oligonucleotide, stimulating their research as agents for the delivery of nucleic acids to living cells.

Role of non-conventional hydrogen bonding in controlling regioselectivity for nucleophilic aromatic substitution of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers: a computational studies

The nucleophilic aromatic substitution reactions of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers, i.e., 1H-1,2,3-triazole and 2H-1,2,3-triazole, have been investigated theoretically using DFT/B3LYP calculations employing 6-31G(d,p) basis set in gas phase as well as in solvent phase. The computational studies have supported the formation of transition states via one-step concerted mechanism for the nucleophilic aromatic displacement of nitro groups with 1,2,3-triazoles rather than intermediate formation via two-step addition-elimination mechanism. The amination of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers have revealed regioselectivity of peri-attack despite sterically favorable para-attack. The regioselectivity is attributed to the stabilization of the transition state through intra-molecular hydrogen bond C-H center dot center dot center dot O=C. This work presents the role of C-H bond as an effective hydrogen bond donor. The molecular interactions through hydrogen bonding have been investigated using AIM method. This work shall result in the synthesis of new regioselective 1,2,3-triazole-derived phthalimide compounds possessing potential biological candidature.
