Monodisperse molecularly imprinted polymers (MIPs) for warfarin (WF), 4′-chlorowarfarin (CWF), (S)-CWF and (R)-CWF (MIPWF, MIPCWF, MIP(S)-CWF and MIP(R)-CWF, respectively) were prepared using 4-vinylpyridine (4-VPY) and ethylene glycol dimethacrylate (EDMA) as a functional monomer and a crosslinker, respectively, by multi-step swelling and polymerization. The molar ratio of a template molecule, 4-VPY to EDMA was 6:18:25 or 4:18:25. The retention and molecular recognition properties of MIPWF and MIPCWF were evaluated using a mixture of sodium phosphate buffer or ammonium formate and acetonitrile in reversed-phase LC. WF and CWF on these MIPs gave the maximal retentions at mobile phase pH 7, and those retentions were decreased with an increase of acetonitrile content. The retention and imprinting factors were in the order of WF < CWF < 4'-bromowarfarin (BWF) on MIPWF and MIPCWF in neutral mobile phases. On the other hands, in acidic mobile phases the retention factors were in the same order with those in neutral mobile phases, while the imprinting factors of WF and CWF were higher on the respective MIPs. These results suggest that ionic or hydrogen bonding interactions, hydrophobic interactions and pi-pi interactions could work for the retention and molecular recognition of WF, CWF and BWF on these MIPs in a reversed-phase mode. Furthermore, MIP(S)-CWF and MIP(R)-CWF could separate WF, CWF and BWF enantiomers in acidic mobile phases. (C) 2021 Elsevier B.V. All rights reserved. Name: 1H-1,2,4-Triazol-5-amine.

Heteroatom-doped ordered mesoporous carbons (OMCs) have currently been considered as promising electrode materials for electrochemical sensors due to the combined advantages of ordered mesoporous materials and heteroatom-doped carbon materials. Herein, a novel nitrogen and sulfur co-doped OMCs (N,S-OMC) has been prepared via a nanocasting strategy with an inexpensive methylene blue as single precursor. The obtained mesoporous carbon has platelet morphology, short mesoporous channel together with a large surface area (549 m(2)/g) as well as rich N- and S-containing functional groups (6.8 at.% N and 2.3 at.% S). Compared with the graphene (GR) and carbon nanotube (CNT) electrode material, the N,S-OMC exhibited a higher electrochemical activity towards the oxidation of herbicide amitrole, ascribable to N,S-OMC’s open mesoporous structures and abundant electroactive defect sites on the carbon skeleton. And, an amitrole electrochemical sensor with N,S-OMC modified electrode as working electrode was fabricated, exhibiting a good selectivity, stability, reproducibility and wide linear range of 3-750 mu M. Moreover, the N,S-OMC-based electrochemical sensor was proved feasible in river water sample analyses, showing a satisfied recovery ranging from 97.03% to 105.42%. The results not only demonstrate cheap methylene blue can be used as single precursor for the N,S-OMC preparation, but also confirm the N,S-OMC is promising in amitrole sensor fabrication.

Impaired synthesis or action of thyroid hormones (THs) during critically sensitive periods of development can have long term adverse effects on health. Development of rapid assays to identify chemicals that impair THs physiology is an important goal for reducing risks from chemical use. Thyroid peroxidase (TPO) is a key enzyme regulating THs synthesis in thyroid gland and a vulnerable target for chemicals that disrupt THs synthesis. To develop a human-relevant, rapid assay for TPO inhibition, we have engineered two cell lines (CHO and LentiX-293) to express active human TPO (hTPO) enzyme and applied them in a recently-described assay using a stable fluorescent product (Amplex UltraRed). Assay performance was assessed by comparing activity of 19 reference chemicals with known strong, weak or no TPO inhibitory activity. The assay using hTPO from either cell line consistently identified the relative potency of strong to moderate inhibitors and chemicals known to be inactive. Results were less consistent for chemicals reported to be weak inhibitors of rodent TPO, possibly suggesting some species specificity. Our studies support the use of hTPO from stably transfected cell lines to substitute for animal-derived thyroid microsomes for rapid high throughput screening assays to identify and characterize TPO inhibitors.

A new naphthalenediimide derivative, 2, 7-di (1, 2, 4-triazolyl) benzophenanthroline-tetraone (3-DTBPT) is synthesized by the condensation reaction of 1, 4, 5, 8-naphthalenetetracarboxylic anhydride (NTCDA) and 3-amino-1, 2, 4-triazole (3-AT). The 3-DTBPT material is characterized by Fourier transform infrared spectrum, X-ray diffraction, thermogravimetric analysis, solid state NMR spectra, field emission scanning electron microscopy, elemental analysis and Brunauer-Emmett-Teller surface. 3-DTBPT is insoluble in organic electrolyte. When used as a cathode material of lithium-ion batteries, 3-DTBPT exhibits an excellent cyclic stability, keeping a specific capacity of 110 mA h g(-1) and a nearly 94.8% capacity retention after 50 cycles at 50 mA g(-1). Our work provides an effective route for overcoming the dissolution problem of organic electrode materials and obtains a potential material for the long-cycle-life and flexible organic rechargeable batteries.

Formula: C2H4N4. I found the field of Metallurgy & Metallurgical Engineering very interesting. Saw the article Chamber Protection of Copper from Atmospheric Corrosion by Compounds of the Triazole Class published in 2020.0, Reprint Addresses Kuznetsov, YI (corresponding author), Russian Acad Sci, AN Frumkin Inst Phys Chem & Electrochem, Moscow 119071, Russia..

Using a set of physicochemical (ellipsometry and contact angle measurements), electrochemical (electrochemical impedance spectroscopy and polarization measurements), and corrosion (periodic moisture condensation and salt fog tests) methods, the properties of adsorption films formed on copper by the chamber method from vapors of benzotriazol (BTA), 1H-1,2,4-triazole, tolyltriazole (TTA), 5-chloro-1,2,3-benzotriazole (CBTA), 3-amino-1H-1,2,4-triazole, and 4-amino-1H-1,2,4-triazole at a temperature of 100 degrees C are studied. It is shown that 1-h chamber treatment of copper with vapors of these compounds leads to the formation of nanoscale hydrophobic adsorption films on it, which inhibits the thermal growth of oxides, but stabilizes the passive state of the metal and increases its corrosion resistance. Among these different triazole compounds tested as chamber corrosion inhibitors, BTA and its substituted derivatives are distinguished. After a 1-h chamber treatment of copper, the protective aftereffect of the adsorption films of triazole derivatives grows symbatically with their saturated vapor pressure at the chamber treatment temperature, i.e., in the following increasing order: CBTA < TTA < BTA. This may indicate that the equilibrium adsorption films do not have time to form at 100 degrees C on the metal within this time period. After a prolonged (24 h or more) chamber treatment of copper with vapors of substituted benzotriazoles, equilibrium adsorption films of inhibitors are formed on it. In this case, the influence of the chamber inhibitor properties on their protective aftereffect alternates. Under such conditions, the least volatile and most hydrophobic substituted benzotriazole, i.e., CBTA, provide the best metal protection.

The chemical behavior of 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]-chromene-6-carbonitrile (khellin-6-carbonitrile) (1) was examined towards a variety of nitrogen nucleophiles. Some novel Schiff bases 5-7 were prepared from reaction of carbonitrile 1 with some heterocyclic amines. Treatment of carbonitrile 1 with some hydrazine derivatives in boiling ethanol afforded pyrazole derivatives 8-13. Khellin-6-carbonitrile (1) reacted with hydrazine hydrate and phenylhydrazine in acetic acid to afford angular heteroannulated furo[3′,2′:6,7]-chromeno [4,3-c]pyrazol-4(1H)-one derivatives 14 and 15. Triazolo[1,5-a]pyrimidine 16 and pyrimido[1,2-a]benzimidazole 17 were synthesized through ring opening and recyclization reactions of compound 1 with 3-amino-1,2,4-triazole and 2-aminobenzimidazole, respectively. Reaction of compound 1 with guanidine and cyanoguanidine in ethanolic potassium hydroxide solution resulted in ring conversion giving the novel angular furo [3 ‘,2’ :6,7] chromeno [4,3-d]pyrimidin-5-ones 18 and 19. The antimicrobial activity of the prepared compounds appeared distinguish activity against the selected microorganisms.

Peroxisomes are metabolically active organelles which are known to exert anti-inflammatory effects especially associated with the synthesis of mediators of inflammation resolution. However, the role of catalase and effects of peroxisome derived reactive oxygen species (ROS) caused by lipid peroxidation through 4-hydroxy-2-nonenal (4-HNE) on lipopolysaccharide (LPS) mediated inflammatory pathway are largely unknown. Here, we show that inhibition of catalase by 3-aminotriazole (3-AT) results in the generation of peroxisomal ROS, which contribute to leaky peroxisomes in RAW264.7 cells. Leaky peroxisomes cause the release of matrix proteins to the cytosol, which are degraded by ubiquitin proteasome system. Furthermore, 3-AT promotes the formation of 4HNE-I kappa B alpha adduct which directly interferes with LPS induced NF-kappa B activation. Even though, a selective degradation of peroxisome matrix proteins and formation of 4HNE- I kappa B alpha adduct are not directly related with each other, both of them are could be the consequences of lipid peroxidation occurring at the peroxisome membrane.

Two energetic compounds, erythritol tetranitrocarbamate (ETNC) and pentaerythritol tetranitrocarbamate (PETNC), and their salts, were synthesized in three steps, characterized and compared. All synthesized compounds were characterized by IR, DSC and multinuclear NMR spectroscopy. Four compounds were further investigated by single crystal X-ray diffraction. All nonmetal salts show extremely low mechanical sensitivity (IS >= 30 J; FS >= 360 N). The heats of formation were calculated using Gaussian 09, and the detonation performances were calculated using EXPLO 5. Although these nonmetal salts are lower than the neutral compounds ETNC (D: 7960 m s(-1), P: 27.4 GPa) and PETNC (D: 7629 m s(-1), P: 24.3 GPa), they possess high detonation performances that are better than TNT. Erythritol-based and corresponding pentaerythritol-based energetic materials were compared in terms of their thermostability, detonation velocity and detonation pressure. They were also compared in their respective series. ETNC and PETNC and their salts have short preparation steps and are easy to isolate in high yields, and thus have promising potential applications as explosives.
