A time-course investigation of resistance to the carboxylic acid amide mandipropamid in field populations of Plasmopara viticola treated with anti-resistance strategies

BACKGROUND Despite anti-resistance strategies being recommended to reduce selection pressure on insensitive strains, no information is available on fungal population dynamics following their application in real field conditions. In this study, the effects on Plasmopara viticola populations of two identical spray programs, differing only in including or not the carboxylic acid amide (CAA) mandipropamid in mixture and in alternation with an anti-resistance partner, were compared in terms of downy mildew control efficacy and mandipropamid sensitivity in two commercial vineyards for four seasons. RESULTS CONCLUSION Both programs effectively and similarly protected grapevine from downy mildew, despite different starting sensitivity levels of the P. viticola populations. In the vineyard where resistant strains were initially present, the frequency of mutations associated with resistance (G1105S/V) fluctuated within seasons in both programs and a shift towards sensitivity occurred after 3 years of the mandipropamid-free program. Where sensitivity was initially present, no changes occurred in the mandipropamid-free program and resistant strains were selected in the mandipropamid program in high disease pressure conditions. The anti-resistance strategy including mandipropamid in mixture showed a good field performance, but did not completely prevent an increase in the frequency of insensitive strains. This supports the need for appropriate planning to determine which mixtures should be used in the field. (c) 2018 Society of Chemical Industry

Green synthesis, in vivo and in vitro pharmacological studies of Tamarindus indica based gold nanoparticles

The current investigation aims to synthesize gold nanoparticles (AuNPs) from aqueous extract of Tamarindus indica and to evaluate the in vitro anti-bacterial and in vivo sedative and anelgescic activities of crude extract as well as synthesized AuNPs. Several methods have been reported to synthesize AuNPs; however, most of them were not ecofriendly. In the present study, the green synthesis of AuNPs has been carried out. Using the green synthesis method, AuNPs of T. indica were synthesized at room temperature (25 degrees C) by mixing 5 mL of HAuCl4 (1 mM) with 1 mL of T. indica seed extract solution. This extract solution was prepared by taking 5 gm dry seeds in 100 mL of double deionized water with continuous stirring for up to 24 h at 80 degrees C. The stability of AuNPs was confirmed with the help of relevant experimental techniques including ultraviolet-visible (UV/Vis) showing maximum absorbance at 535-540 nm, Fourier transform infrared showing a broad signal at 3464 cm(-1) which can be attributed to either amide or hydroxyl functionalities and atomic force microscopy analysis showed that the biomaterial surrounding AuNPs was agglomerated which proves the formation of discrete nanostructutres. These AuNPs have been evaluated for their antibacterial potential. The results revealed good antibacterial activity of the samples against. Klebsiella pneumonia, Bacillus subtilis and Staphylococcus epidermidis with 10-12 mm zone of inhibition range. The AuNPs were also found stable at high temperature, over a range of pH and in 1 mM salt solution. Moreover, the crude extract and respective AuNPs also exhibited interesting sedative and analgesic activities. Hence, we focused on phytochemicals-mediated synthesis of AuNPs considered as greatest attention in the treatment of anti-bacterial, analgesic, and sedative.

Molecular Control of Heterogeneous Electrocatalysis through Graphite Conjugation

CONSPECTUS: The efficient interconversion of electrical and chemical energy requires catalysts capable of accelerating multielectron reactions at or near electrified interfaces. These reactions can be performed at metallic surface sites on heterogeneous electrocatalysts or through redox mediation at molecular electrocatalysts. The relative ease of synthesis and characterization for homogeneous catalysts has allowed for molecular-level control over the active site and permitted systematic tuning of activity and selectivity. Similar control is difficult to achieve with heterogeneous electrocatalysts, because they typically exhibit a distribution of active site geometries and local electronic structures, which are challenging to modify with molecular precision. However, metallic heterogeneous electrocatalysts benefit from a continuum of electronic states that distribute the redox burden of multielectron transformations, enabling more efficient catalysis. We envisioned that we could combine the attractive properties of molecular and heterogeneous catalysts by integrating tunable molecular active sites into the delocalized band states of a conductive solid. The Surendranath group has developed a class of electrocatalysts in which molecules are strongly electronically coupled to graphitic electrodes through a conductive, aromatic pyrazine linkage such that they behave like metallic surface active sites. In this Account, we discuss the dual role of these graphite-conjugated catalysts (GCCs) as a platform with which to answer molecular-level questions of metallic active sites and as a tool with which to fundamentally alter the mechanism and enhance the performance of molecular active sites. We begin by describing the electrochemical and spectroscopic studies that demonstrated that GCC sites behave like metallic active sites rather than simply as redox mediators attached to electrode surfaces. We then discuss how electrochemical studies of a series of graphite-conjugated acids enabled the construction of a molecular model for the thermochemistry of proton-coupled electron transfer reactions at GCC sites based on the pK(a) of the molecular analogue of the conjugated site and the potential of zero free charge of the electrode. In the final section, we discuss the effects of graphite conjugation on the mechanism and rate of oxygen reduction, hydrogen evolution, and carbon dioxide reduction catalysis across four different GCC platforms involving N-heterocycle, organometallic, and metalloporphyrin active sites. We discuss how molecular-level tuning at graphite-conjugated active sites directly correlates to changes in catalytic activity for the oxygen reduction reaction. We demonstrate that graphite-conjugated porphyrins show enhanced catalytic oxygen reduction activity over amide-linked porphyrins. Lastly, we describe how catalysis at graphite-conjugated sites proceeds through mechanisms involving concerted electron transfer and substrate activation, in stark contrast to the mechanisms observed for molecular analogues. Overall, we showcase how GCCs provide a rich platform for controlling heterogeneous catalysis at the molecular level.

High quality and high performance adsorption of Congo red using as-grown MWCNTs synthesized over a Co-MOF as a catalyst precursor via the CVD method

A Co(II) metal-organic framework (MOF) based on the pyridyl-amide-carboxylate-3-(2-pyridinecarboxylic acid) amido pyridine (HPCAP) ligand, namely [Co(PCAP)(2)]center dot 2H(2)O (1), has been hydrothermally synthesized and structurally characterized, which was firstly used as a combined catalyst precursor to synthesize multi-walled carbon nanotubes (MWCNTs). The decomposition of ethylene in the presence of the Co-MOF by the chemical vapor deposition (CVD) method at 800 degrees C led to successful production of high quality as-grown MWCNT products. Interestingly, the as-grown MWCNTs exhibit high performance in the selective adsorption of Congo red (CR) with an adsorption capacity of 1639 mg g(-1).

Alginate/Cucurbit[7]uril/Dequalinium-Based Supramolecular Carbohydrates: Modulation of FRET Signals by Temperature Control

Herein, we describe the synthesis of a bioactive, inexpensive, and easy-to-handle supramolecular carbohydrate polymer by grafting of cucurbit[7]uril macrocycle (CB7)-encapsulated dequalinium chloride hydrate (DCH) onto alginic acid carbohydrates (ALG) via amide linkage formation and show that light energy transfer based on energy migration can be controlled by altering polymer temperature without changing polymer composition. DCH (donor) and 2-anilinonaphthalene-6-sulfonic acid (acceptor) were used to generate Forster resonance energy transfer (FRET) signals. Stationary and time-resolved photoluminescence spectra of the modified carbohydrate platform revealed that FRET resulted in a color change from violet (similar to 387 nm) to blue (similar to 429 nm), which could be repeatedly switched on and off in response to temperature stimuli at 298-368 K. Temperature-dependent NMR measurements suggested that the responsiveness of DCH/CB7ALG to thermal stimuli was due to the threading of CB7 onto the DCH backbone in solution and upon grafting onto ALG polymers.

Variously substituted 2-oxopyridine derivatives: Extending the structure-activity relationships for allosteric modulation of the cannabinoid CB2 receptor

We previously reported the 2-oxopyridine-3-carboxamide derivative EC21a as the first small synthetic CB2R positive allosteric modulator which displayed antinociceptive activity in vivo in an experimental mouse model of neuropathic pain. Herein, we extended the structure-activity relationships of EC21a through structural modifications regarding the p-fluoro benzyl moiety at position 1 and the amide group in position 3 of the central core. The characterization in vitro was assessed through radioligand binding experiments and functional assays (GTP gamma S, cAMP, beta arrestin2). Among the new compounds, the derivatives Al (SV-10a) and A5 (SB-13a) characterized respectively by fluorine atom or by chlorine atom in ortho position of the benzylic group at position 1 and by a cycloheptane-carboxamide at position 3 of the central core, showed positive allosteric behavior on CB2R. They enhanced the efficacy of CP55,940 in [S-35]GTP gamma S assay, and modulated CP55,940-dependent beta arrestin2 recruitment and cAMP inhibition. The obtained results extend our knowledge of the structural requirements for interaction with the allosteric site of CB2R. (C) 2020 Elsevier Masson SAS. All rights reserved.

Radiation Stability of Epoxy-Based Gamma Shielding Material

A comprehensive investigation on the effect of gamma radiation on epoxy-lead oxide composites has been carried out highlighting upon the chemical structure, thermal stability, mechanical stability, surface morphology and gamma attenuation properties. FTIR analysis evidenced the irradiation effect leading to the formation of ketones and amides due to chain scission of the epoxy polymer backbone. Surface damages were observed at high gamma dose in optical micrographs which was controlled by lead oxide. The decrease in thermal stability and activation energy with gamma dose was observed in TGA analysis. Nanoindentation studies demonstrated the decreases in surface hardness and modulus at a higher dose. However, the attenuation properties and XRD spectrum of the composites remain unchanged upon 1000 kGy gamma radiation dose.

Reusable Fe2O3-nanoparticle catalysed efficient and selective hydroboration of carbonyl compounds

The first Fe2O3-nanoparticle catalysed hydroboration of aromatic and aliphatic aldehydes and ketones with HBpin (pin = OCMe2CMe2O) is reported. The reaction proceeds under mild conditions (room temperature) and is moderately sensitive to air. This process is applicable to a broad range of substrates with high functional group compatibility. Moreover, aldehydes are selectively hydroborated over other reducible functional groups, such as ketone, nitrile, hydroxide, alkene, amide, ester, nitro and halide groups.

Prolinamides of Aminouracils, Organocatalyst Modifiable by Complementary Modules

We report the synthesis and evaluation of prolinamide organocatalysts that incorporate aminouracils. The features of these catalysts are enhanced NH acidity of the amide because of the electron-withdrawing nature of the heterocycle, an additional hydrogen-bond donor at the alpha or beta positions of this functional group (using 6-aminouracil or 5,6-diaminouracil respectively), and it can be recovered due to its low solubility and used again without decreasing the enantioselectivity. A unique feature of these systems is the self-assembly capability with complementary modules by Watson-Crick interactions. These supramolecular adducts behave differently from the catalyst alone, some of them have lower performance but others improve the selectivity of the product. Therefore, this approach avoids the synthesis of many catalysts.

Cobalt Amide Imidate Imidazolate Frameworks as Highly Active Oxygen Evolution Model Materials

Two imidazolate-based Co-MOFs, IFP-5 and IFP-8 (imidazolate framework Potsdam), with a different peripheral group -R (-Me and -OMe, respectively) have been synthesized by a solvothermal method and tested toward the oxygen evolution reaction (OER). Remarkably, IFP-8 presents much lower overpotentials (319 mV at 10 mA/cm(2) and 490 mV at SOO mA/cm(2)) than IFP-5 toward OER, as confirmed by online gas chromatography measurements (Faradaic yield of O-2 > 99%). Moreover, the system is extraordinarily stable during 120 h, even when used as a catalyst toward the overall water splitting reaction without any sign of fatigue. An integrated ex situ spectroscopic study, based on powder X-ray diffraction, extended X-ray absorption fine structure, and attenuated total reflection, allows the identification of the active species and the factors that determine the catalytic activity. Indeed, it was found that the performances are highly affected by the nature of the -R group, because this small change strongly influences the conversion of the initial metal organic framework to the active species. As a consequence, the remarkable activity of IFP-8 can be ascribed to the formation of Co(O)OH phase with a particle size of a few nanometers (3-10 nm) during the electrocatalytic oxygen evolution.
