Incorporating lines of evidence from New Approach Methodologies (NAMs) to reduce uncertainties in a category based read-across: A case study for repeated dose toxicity

A group of triazole compounds was selected to investigate the confidence that may be associated with read-across of a complex data gap: repeated dose toxicity. The read-across was evaluated using Assessment Elements (AEs) from the European Chemicals Agency’s (ECHA’s) Read-Across Assessment Framework (RAAF), alongside appraisal of associated uncertainties. Following an initial read-across based on chemical structure and properties, uncertainties were reduced by the integration of data streams such as those from New Approach Methodologies (NAM) and other existing data. In addition, addressing the findings of the ECHA RAAF framework, complemented with specific questions concerning uncertainties, increased the confidence that can be placed in read-across. Although a data rich group of compounds with a strong mechanistic basis was analysed, it was clearly demonstrated that NAM data available from publicly available resources could be applied to support read-across. It is acknowledged that most read-across studies will not be so data rich or mechanistically robust, therefore some targeted experimentation may be required to fill the data gaps. In this sense, NAMs should constitute new experimental tests performed with the specific goal of reducing the uncertainties and demonstrating the read-across hypothesis.

A review on the stereospecific fate and effects of chiral conazole fungicides

The production and use of chiral pesticides are triggered by the need for more complex molecules capable of effectively combating a greater spectrum of pests and crop diseases, while sustaining high production yields. Currently, chiral pesticides comprise about 30% of all pesticides in use; however, some pesticide groups such as conazole fungicides (CFs) consist almost exclusively of chiral compounds. CFs are produced and field-applied as racemic (1:1) mixtures of two enantiomers (one chiral center in the molecule) or four diastereoisomers, i.e., two pairs of enantiomers (two chiral centers in the molecule). Research on the stereoselective environmental behavior and effects of chiral pesticides such as CFs has become increasingly important within the fields of environmental chemistry and ecotoxicology. This ismotivated by the fact that currently, the fate and effects of chiral pesticides such as CFs that arise due to their stereoselectivity are not fully understood and integrated into risk assessment and regulatory decisions. In order to fill this gap, a summary of the state-of-the-art literature related to the stereospecific fate and effects of CFs is needed. This will also benefit the agrochemistry industry as they enhance their understanding of the environmental implications of CFs which will aid future research and development of chiral products. This review provides a collection of >80 stereoselective studies for CFs related to chiral analyticalmethods, fungicidal activity, non-target toxicity, and behavior of this broadly used pesticide class in the soil environment. In addition, the review sheds more light on mechanisms behind stereoselectivity, considers possible agricultural and environmental implications, and suggests future directions for the safe use of chiral CFs and the reduction of their environmental footprint.

Sterol 14 alpha-Demethylase Ligand-Binding Pocket-Mediated Acquired and Intrinsic Azole Resistance in Fungal Pathogens

The fungal cytochrome P450 enzyme sterol 14 alpha-demethylase (SDM) is a key enzyme in the ergosterol biosynthesis pathway. The binding of azoles to the active site of SDM results in a depletion of ergosterol, the accumulation of toxic intermediates and growth inhibition. The prevalence of azole-resistant strains and fungi is increasing in both agriculture and medicine. This can lead to major yield loss during food production and therapeutic failure in medical settings. Diverse mechanisms are responsible for azole resistance. They include amino acid (AA) substitutions in SDM and overexpression of SDM and/or efflux pumps. This review considers AA affecting the ligand-binding pocket of SDMs with a primary focus on substitutions that affect interactions between the active site and the substrate and inhibitory ligands. Some of these interactions are particularly important for the binding of short-tailed azoles (e.g., voriconazole). We highlight the occurrence throughout the fungal kingdom of some key AA substitutions. Elucidation of the role of these AAs and their substitutions may assist drug design in overcoming some common forms of innate and acquired azole resistance.

A Cu-4 cluster-based MOF as a supercapacitor electrode material with ultrahigh capacitance

Developing new pristine metal-organic framework (MOF)-based electrode material for high-performance supercapacitors is a considerable attractive task. Herein, a Cu-4 cluster-based three-dimensional (3D) MOF ([Cu-4(mu(3)-OH)(2)(atrz)(2)(1,3-BDC)(3)]center dot 2H(2)O, Cu-atrz-BDC; atrz, 4-amino-1,2,4-triazole; 1,3-H2BDC, 1,3-benzenedicarboxylic acid) was synthesized and characterized by infrared spectroscopy, X-ray powder diffraction, thermogravimetric analysis, nitrogen adsorption-desorption, scanning electron microscopy, and X-ray photoelectron spectroscopy. The Cu-atrz-BDC firstly was used as an electrode material for supercapacitor. In a three-electrode system, the Cu-atrz-BDC electrode exhibited ultrahigh specific capacitance of 5525 F g(-1) at 1 A g(-1) and its specific capacitance can also keep about 886 F g(-1) after 1000 cycles at 3 A g(-1). Importantly, the Cu-atrz-BDC as the positive electrode and the rGO as the negative electrode were assembled into an asymmetric supercapacitor with excellent cycling stability, displaying the maximum energy density of 9.96 Wh kg(-1) at a power density of 0.81 kW kg(-1). The high supercapacitive performance might be ascribed to its porous three-dimensional structure, the nanosized particles, and better conductivity.

Enantioselective Analysis and Degradation Studies of Four Stereoisomers of Difenoconazole in Citrus by Chiral Liquid Chromatography-Tandem Mass Spectrometry

Four difenoconazole stereoisomers were well separated on a Superchiral S-OX column. The absolute configurations of the four stereoisomers of difenoconazole eluted in an orderly fashion with the chiral column were confirmed as (2S,4S), (2S,4R), (2R,4R), and (2R,4S)-difenoconazole, respectively, by single-crystal X-ray diffraction. For the first time, a simple and efficient trace detection method for the determination of residues of the four stereoisomers of difenoconazole in a plant sample by HPLC-MS/MS was developed. The mean recoveries were 78.23-104.38% with RSDs of 0.33-9.95%. The limits of detection for the four difenoconazole enantiomers were 0.0002-0.0004 mg/kg, and the limits of quantitation were 0.0044-0.011 mg/kg in citrus leaves and whole fruits. There was no obvious enantioselectivity upon degradation of the four stereoisomers in citrus leaves and whole fruits in Hunan and Guizhou. In Guangzhou, the rate of degradation of (2R,4R)-difenoconazole was the slowest among the four stereoisomers of difenoconazole.

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.

4-Substituted-1,2,3-triazolo nucleotide analogues as CD73 inhibitors, their synthesis, in vitro screening, kinetic and in silico studies

Three series of nucleotide analogues were synthesized and evaluated as potential CD73 inhibitors. Nucleobase replacement consisted in connecting the appropriate aromatic or purine residues through a triazole moiety that is generated from 1,3-dipolar cycloaddition. The first series is related to 4-substituted-1,2,3-triazolo-beta-hydroxyphosphonate ribonucleosides. Additional analogues were also obtained, in which the phosphonate group was replaced by a bisphosphonate pattern (P-C-P-C, series 2) or the ribose moiety was removed leading to acyclic derivatives (series 3). The beta-hydroxyphosphonylphosphonate ribonucleosides (series 2) were found to be potent inhibitors of CD73 using both purified recombinant protein and cell-based assays. Two compounds (2a and 2b) that contained a bis(trifluommethyl)phenyl or a naphthyl substituents proved to be the most potent inhibitors, with IC50 values of 4.8 +/- 0.8 04 mu M and 0.86 +/- 0.2 mu M, compared to the standard AOPCP (IC50 value of 3.8 +/- 0.9 mu M), and were able to reverse the adenosine-mediated immune suppression on human T cells. This series of compounds illustrates a new type of CD73 inhibitors.

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.
