Spectroscopic and electrochemical recognition of H2PO4- based on a ruthenium complex with 2-picolinamide

A ruthenium polypyridyl complex 4(PF6) with 2-picolinamide as an anionic N <^> N bidentate ligand is synthesized and characterized, including single-crystal X-ray analysis. As an effective anion receptor in CH2Cl2, complex 4(PF6) shows selective spectroscopic and electrochemical recognition towards H2PO4- over other anions tested (F-, Cl-, Br-, I-, HP2O73-, HSO4-, AcO- and NO3-). Job’s plot and mass spectral analyses support that an adduct is formed between 4 and H2PO4- with a 1:2 binding stoichiometry. The absorption spectral titration of 4(PF6) with H2PO4- yields a global association constant in the order of 10 8 L-2.mol(-2) and an optical detection limit of 1.4 x 10(-6) mol.L-1. In response to the presence of H2PO4-, the Ru(II/III) redox couple of 4(PF6) displays a two-wave behavior accompanied by a large negative shift from + 0.74 to + 0.45 V vs Ag/AgCl. H-1 NMR spectral titration analyses suggest that effective hydrogen bonding interactions are present between 4 and H2PO4-, which are believed responsible for the observed spectroscopic and electrochemical response of 4(PF6) toward H2PO4-.

Bis-BODIPY linked-triazole based on catechol core for selective dual detection of Ag+ and Hg2+

Herein, we introduced a new chemosensor, bis-BODIPY linked-triazole based on catechol (BODIPY-OO) prepared by bridging two units of BODIPY fluorophore/triazole binding group with a catechol unit. A solution of this compound displayed 4- and 2-fold enhancements in fluorescence intensity after adding a mole equivalent amount of Ag+ and Hg2+ ions in methanol media, respectively. H-1 NMR titrations of BODIPY-OO with Ag+ and Hg2+ suggested that the triazole was involved in the recognition process. BODIPY-OO showed high sensitivity toward Ag+ and Hg2+ over other metal ions with detection limits of 0.45 mu M and 1 mu M, respectively. It can also distinguish Hg2+ from Ag+ by addition of an EDTA. This compound can therefore be employed as practical fluorescent probe for monitoring the presence of Ag+ and Hg2+ ions.

Pesticides and their degradates in groundwater reflect past use and current management strategies, Long Island, New York, USA

Long Island, New York, has a mix of urban/suburban to agricultural/horticultural land use and nearly 3 million residents that rely on a sole-source aquifer for drinking water. The analysis of shallow groundwater (<40 m below land surface) collected from 54 monitoring wells across Long Island detected 53 pesticides or pesticide degradates. Maximum concentrations for individual pesticides or pesticide degradates ranged from 3 to 368,000 ng/L. The highest concentrations andmost frequent pesticide detections occurred in samples collected from the pesticide management (PM) network, set in an agricultural/horticultural area in eastern Long Island with coordinated pesticide management by state and local agencies. The other two networks (Suffolk and Nassau/Queens) were set in suburban and urban areas, respectively, and had less frequent detections and lower pesticide concentrations than the PMnetwork. Pesticide detections and concentration patterns (herbicide, insecticide, or fungicide) differed among the three networks revealing broad differences in land use. The predominance of fungicides metalaxyl, 1H-1,2,4-triazole (propiconazole/myclobutanil degradate), and 4-hydroxychlorothalonil (HCTL, chlorothalonil degradate) in samples from the PM network reflects their intensive use in agricultural settings. Total fungicide concentrations in the PM network ranged from <10 to >300,000 ng/L. Thewidespread detection of imidacloprid and triazine herbicides, simazine and atrazine, reveal a mixture of current and past use pesticides across the Long Island region. Low concentrations (<200 ng/L) of the triazines in the Suffolk and Nassau/Queens networks may reflect a change in land use and application. Acetanilide herbicides and aldicarb have been discontinued for 20 and 40 years, respectively, yet the concentrations of their degradates were among the highest observed in this study. Acetanilide (total concentrations up to 10,000 ng/L) and aldicarb degradates (up to 270 ng/L) are present in the PM network at much lower concentrations than previous Long Island studies and reflect changes in agricultural practices and pesticide management.

1,3-Dipolar Cycloaddition: Free Catalytic Synthesis and Esophageal Cancer Activity of New 1,2,3-Triazole-Oxydianiline-Maleimide Hybrids

A new series of 1,2,3-triazole-oxydianiline-maleimide hybrids 12-15 was synthesized by using 1,3-dipolar cycloaddition reaction of N-Arylmaleimides 6-9 with 4,4′-oxybis(azidobenzene) 11 under an efficient and free catalytic reaction. All the newly synthesized hybrids were characterized by their H-1 NMR, F-TIR, Mass spectral data and melting points. The cytotoxic activities (in vitro) of selected hybrids against esophageal cancer of human cell line (SKG) were evaluated by MTT assay. Among them, hybrid 13 exhibited a potent inhibition activity with the IC50 value of 1.61 +/- 0.01 mu M against esophageal cancer cell (SKG). Cellular mechanism investigations in esophageal carcinoma cells (SKG) elucidated that hybrid 13 inhibited cell growths in vitro and arrested cell cycle at an environmental phase. These results revealed that hybrid 13 holds a promising anticancer agent with the enhancement of further clinical applications in drug discovery field.

A real-time and highly sensitive fiber optic biosensor based on the carbon quantum dots for nitric oxide detection

Nitric oxide (NO) is a signal molecule with a wide range of functions and unique properties in organisms. A novel fluorescent probe composed of carbon quantum dots (CQDs) with o-phenylenediamine groups was prepared by the microwave method to detect NO selectively. The mechanism of the reaction between CQDs and NO was established by a series of characterization methods, such as fluorescence spectrophotometer, UV-vis absorption spectrophotometer and transmission electron microscope. The result showed that the o-phenylenediamine groups on the surface of the CQDs can react with NO to form an electron-free triazole structure, leading to the decrease of fluorescence of the CQDs. Furthermore, a new optical fiber sensing system based on the CQDs was constructed to detect NO with a low detection limit of 9.12 nM at laser power of 280 mW. In addition, the NO optic fiber biosensor also was used to detect NO concentration in real human serum samples.

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.

Thiol-functionalized multiwall carbon nanotubes for electrochemical sensing of thallium

An electrochemical sensor is fabricated using indium tin oxide (ITO) electrode loaded with 3-Amino-1,2,4-triazole-5-thiol functionalized multiwall carbon nanotubes (T-MWCNTs) for detection of thallium. The modified MWCNTs were characterized by FTIR spectroscopy, SEM and HRTEM studies. SEM images demonstrated that the width of tubular structure of T-MWCNTs increase considerably after functionalization. The electrochemical response of the prepared sensor is analysed by performing differential pulse anodic stripping voltammetry (DPASV). T-MWCNTs based sensor was found to exhibit good sensitivity and a broad linear range of 10-100 mu g L-1 along with a limit of detection (LOD) of 1.29 mu g L-(1) for Tl(I). The sensor showed good repeatability (RSD of 1.16% and 2.09% for 20 and 50 mu g L-1 concentrations of Tl(I) respectively) and retained similar to 95% of its response even after 15 days, indicating high stability of T-MWCNTs/ITO/glass electrode towards the detection of thallium. The applicability of the prepared sensor was analysed in real industrial water samples with the help of spiking study that was performed using certified Tl(I) solution traceable to National Institute of Standards and Technology (NIST) and demonstrated a recovery > 96%.

Iridium-Catalyzed Direct Amidation of Imidazoles at the C-2 Position with Isocyanates in the Presence of Hydrosilanes Leading to Imidazole-2-Carboxamides

Regioselective coupling reaction of N-substituted imidazoles with isocyanates in the presence of a stoichiometric amount of hydrosilanes catalyzed by Ir-4(CO)(12) to give imidazole-2-carboxamides is reported. Imidazoles bearing an (O-silyl)carboximidate group at the 2-position appear to be initially formed in the reaction; these are then hydrolyzed to the final products in situ. The addition of the hydrosilane was essential for the catalytic reaction to proceed. Substituents on the imidazole ring had no effect on the reaction, except for certain bulky substituents such as tBu and Ph groups at the 4-position. Triazoles such as 4-methyl-4H-1,2,4-triazole and 1-methyl-1H-1,2,4-triazole were also applicable to this C-H amidation, and the latter reaction proceeded regioselectively at the carbon atom between the sp(3) and sp(2) nitrogen atoms of the ring, and not between the two sp(2) nitrogen atoms.

Design, synthesis, and in vitro and in vivo anti-angiogenesis study of a novel vascular endothelial growth factor receptor-2 (VEGFR-2) inhibitor based on 1,2,3-triazole scaffold

In the past five years, our team had been committed to click chemistry research, exploring the biological activity of 1,2,3-triazole by synthesizing different target inhibitors. In this study, a series of novel indole-2-one derivatives based on 1,2,3-triazole scaffolds were synthesized for the first time, and their inhibitory activity on vascular endothelial growth factor receptor-2 (VEGFR-2) was tested. Most of the compounds had shown promising activity in the VEGFR-2 kinase assay and had low toxicity to human umbilical vein endothelial cells (HUVECs). The compound 13d (IC50 = 26.38 nM) had better kinase activity inhibition ability than sunitinib (IC50 = 83.20 nM) and was less toxic to HUVECs. Moreover, it had an excellent inhibitory effect on HT-29 and MKN-45 cells. On the one hand, by tube formation assay, transwell, and Western blot analysis, compound 13d could inhibit VEGFR-2 protein phosphorylate on HUVECs, thereby inhibiting HUVECs migration and tube formation. In vivo study, the zebraflsh model with VEGFR-2 labeling also verified that compound 13d had more anti-angiogenesis ability than sunitinib. On the other hand, molecular docking and molecular dynamics (MD) simulation results showed that compound 13d could stably bind to the active site of VEGFR-2. Based on the above findings, compound 13d could be considered an effective anti-angiogenesis drug and has more development value than sunitinib. (C) 2020 Elsevier Masson SAS. All rights reserved.
