In the present paper, twelve Schiff bases derived from 3-amino-1H-1,2,4-triazole (ATz) and various benzaldehydes, and salicylaldehydes were synthesized. The H-1, C-13, and N-15 NMR data are discussed in relation to the structure of ATz and its imine products. In addition, X-ray, ATR-FTIR, and UV-Vis analytical techniques are used for structure elucidation of ATz-based Schiff bases. It was found that the starting material, 3-amino-1H-1,2,4-triazole, exists as tautomeric mixture of three forms (Graphical Abstract) in solution, whereas in the solid state (C-13 and N-15 CPMAS data) potentially tautomeric proton is located on nitrogen atom traditionally marked as N-2 (Graphical Abstract, 2N-H structure). All investigated Schiff bases derived from salicylaldehydes exist in both phases as tautomeric equilibrium mixtures, where enol-imine forms are dominated structures. The positions of those equilibria only very slightly depend on substituents in phenol ring. Generally, the contributions of keto-amine forms in the solid state are higher comparing with DMSO solutions. (C) 2019 Published by Elsevier B.V.

Mitochondria are known as powerhouse of cells and play the role of a bridge in redox balance, cell apoptosis, and autophagy. ROS accumulation can cause mitochondria damage, while the injured mitochondria will further enhance ROS levels reciprocally. Herein, we synthesized a novel series of [1,2,4] triazolo[1,5-a]pyrimidine-based compounds 4a-4v and tested their anti-proliferation efficacy against gastric cancer cell line MGC-803. Among them, compounds 4o and 4p inhibited gastric cancer cells at micromolar level. Compound 4o caused G2/M arrest and induced mitochondria-dependent apoptosis in MGC-803 and SGC-7901. However, inhibiting apoptosis pathway cannot prevent the inhibitory activity of compound 4o against gastric cancer cell. To our surprising, ROS level was increased by compound 4o and elevation of ROS could be rescued by NAC. In accordance with that, NAC absolutely prevented the anti-proliferation efficacy of compound 4o. We further found that autophagy inhibitor CQ rather than 3-MA partially reversed inhibitory activity of compound 4o in MGC-803 cells. Taken together, compound 4o exhibited its anti-proliferative activity via increasing ROS level and inducing autophagy, thus leading to apoptosis of gastric cancer cells. Therefore, compound 4o may support further development of lead compounds for gastric cancer therapy via mitochondria pathway. (C) 2020 Elsevier Masson SAS. All rights reserved.

Under both conventional and microwave methods, 2-amino-4H-pyran-3-carbonitrile derivative 1 was synthesized and reacted with different reagents. Thus, 2-amino-4H-pyran-3-carbonitrile derivative was treated with chloroacetyl chloride, phenyl isocyanate, cyanoacetic acid, benzoyl chloride, triethyl orthoformate, acetic anhydride/H2SO4, arylidene malononitrile, urea, and/or p-aminosulphaguanidine producing chloroacetamide, 3-phenylurea, cyanoacetamide, N-benzoylpyran, ethylformimidate, pyranopyrimidin-4-one, pyranopyridine, pyranopyrimidin-2-one, and pyranopyrimidin-2-imine derivatives, respectively. Meanwhile, compound 1 was reacted with ethyl bromoacetate, phenacyl bromide, phthalic anhydride, different aromatic amines, and/or acetic acid/H2SO4 to produce 5-aminopyrano[2,3-b]pyrrole-6-carboxylate, dihydropyrano[2,3-b]pyrrole-6-yl-(phenyl)methanone, 1,3-dioxoisoindolinyl pyran, 1,4-dihydropyridine, and 2-hydroxy-1,4-dihydropyridine derivatives, respectively. On the other hand, when compound 1 was allowed to react with maleic anhydride and/or hydrazine hydrate, pyran-4-oxobut-2-enoic acid and 3-aminopyranopyrazole derivatives were obtained, respectively. Reaction of pyran-4-oxobut-2-enoic acid with malononitrile under different conditions gave 2-(furan-2-yl)-4H-pyran and 2-(4H-pyran-2-yl)-1H-pyrrole derivatives, while condensation of 3-aminopyranopyrazole with benzaldehyde gave 1,4-dihydropyrano[2,3-c]pyrazol-3-yl-1-phenylmethanimine derivative. The newly synthesized compounds were characterized by the spectroscopic tools IR, H-1-NMR, C-13-NMR, MS, and elemental analysis. Some of these compounds have been screened in vitro for antimicrobial activity against different strains of bacteria and fungi and also were tested against two cancer cell lines: mammary gland breast cancer (MCF-7) and colon cancer (HCT-118).

This work introduces a new additive named 4,4′-trimethylenedipiperidine for the practical and ecofriendly preparation of ethyl 5-amino-7-(4-phenyl)-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylate derivatives. This chemical is commercially available and easy to handle. It also possesses a low melting point and a broad liquid range temperature, high thermal stability, and good solubility in water. Based on green chemistry principles, the reaction was performed in a) a mixture of green solvents i.e. water and ethanol (1:1 v/v) at reflux temperature, and b) the additive was liquefied at 65 degrees C and the reaction was conducted in the liquid state of the additive. High yields of the desired triazolo-pyrimidines were obtained under both aforementioned conditions. Our results demonstrated that this additive, containing 2 Lewis base sites and able to act as an acceptor-donor hydrogen bonding group, is a novel and efficient alternative to piperidine, owing to its unique properties such as its reduced toxicity, nonflammable nature, nonvolatile state, broad liquid range temperature, high thermal stability, and ability to be safely handled. Furthermore, this additive could be completely recovered and exhibited high recyclability without any change in its chemical structure and no significant reduction in its activity. The current methodology has several advantages: (a) it avoids the use of hazardous materials, as well as toxic, volatile, and flammable solvents, (b) it does not entail tedious processes, harsh conditions, and the multistep preparation of catalysts, (c) it uses a metal-free and noncorrosive catalyst, and (d) reduces the generation of hazardous waste and simple work-up processes. The most important result of this study is that 4,4′-trimethylenedipiperidine can be a promising alternative for toxic, volatile, and flammable base reagents in organic synthesis owing to its unique properties.

A highly sensitive dual-signal aptamer sensor based on polydopamine-gold nanoparticles (PDA-AuNPs) and exonuclease I (Exo I) was developed for detection of malathion. Compared with traditional sensing elements, aptamer has many advantages, such as high affinity, superior specificity, strong stability and easy modification. The electrodeposition synthesis of PDA-AuNPs gave excellent biocompatibility and electrical conductivity on the sensor. With the addition of malathion, the specific interaction between malathion and its aptamer forced the aptamer to detach from the electrode surface and induced the capture probe to form a hairpin structure on the electrode surface. Exo I was added to motivate the autocatalytic target cycling which remarkably increased the current change of electrochemical signal over 2 times. Therefore, the promising strategy gave rise to an optional dual-signal current readout in both the signal-on of Fc and the signal-off of Tn. In this work, the prepared biosensor exhibited high sensitivity to malathion via the combination of dual-signal design and autocatalytic target cycling amplification. Under the optimized conditions, the proposed sensor showed a wide linear range from 0.5 to 600 ng/L malathion. It also exhibited excellent specificity, acceptable repeatability and good stability. The application of real samples obtained satisfactory recovery results, demonstrating a promising potential in food safety analysis.

Intracerebroventricular (icv) injection of hydrogen peroxide (H2O2), a reactive oxygen species, or the blockade of catalase (enzyme that degrades H2O2 into H2O and O-2) with icv injection of 3-amino-1,2,4-triazole (ATZ) reduces the pressor effects of angiotensin II also injected icv. In the present study, we investigated the effects of ATZ injected icv or intravenously (iv) on the pressor responses induced by icv injections of the cholinergic agonist carbachol, which similar to angiotensin II induces pressor responses that depend on sympathoexcitation and vasopressin release. In addition, the effects of H2O2 icv on the pressor responses to icv carbachol were also tested to compare with the effects of ATZ. Normotensive non-anesthetized male Holtzman rats (280-300 g, n = 8-9/group) with stainless steel cannulas implanted in the lateral ventricle were used. Previous injection of ATZ (5 nmol/1 mu l) or H2O2 (5 mu mol/1 mu l) icv similarly reduced the pressor responses induced by carbachol (4 nmol/1 mu l) injected icv (13 +/- 4 and 12 +/- 4 mmHg, respectively, vs. vehicle + carbachol: 30 +/- 5 mmHg). ATZ (3.6 mmol/kg of body weight) injected iv also reduced icv carbachol-induced pressor responses (21 +/- 2 mmHg). ATZ icv or iv and H2O2 icv injected alone produced no effect on baseline arterial pressure. The treatments also produced no significant change of heart rate. The results show that ATZ icv or iv reduced the pressor responses to icv carbachol, suggesting that endogenous H2O2 acting centrally inhibits the pressor mechanisms (sympathoactivation and/or vasopressin release) activated by central cholinergic stimulation.

Six novel ruthenium(III) complexes of general formula [RuCl3(L)(3)] (1,3,5) and [RuCl3(H2O)(L)(2)] (2,4,6), where L stands for three different triazolopyrimidine-derived ligands, are reported. The compounds have been structurally characterized (IR, EPR, SCXRD), and their magnetic moments have been determined. The single-crystal X-ray diffraction study revealed a slightly distorted octahedral geometry of the Ru(III) complexes with mer configuration in 1 and 5, and fac configuration in 3. In 2 and 4, three chloride ions are in mer configuration and the two triazolopyrimidines are oriented trans mutually with the water molecule playing the role of the sixth ligand. All complexes have been thoroughly screened for their in vitro cytotoxicity against human breast cancer cell line MCF-7, human cervical cancer cell line HeLa, and L929 murine fibroblast cells, uncovering among others that the most lipophilic complexes 5 and 6, containing the bulky ligand dptp (5,7-diphenyl-1,2,4-triazolo[1,5-a]pyrimidine), display high cytotoxic activity against MCF-7, and HeLa cells. Moreover, it was also revealed that during the interaction of the complexes 1-6 with the cancer MCF-7 cell line, reactive oxygen species are released intracellularly, which could indicate that they are involved in cell apoptosis. Furthermore, extensive studies have been carried out to reveal the mechanism by which complexes 1-6 interact with DNA, albumin, and apotransferrin. The biological studies were complemented by detailed kinetic studies of the hydrolysis of the complexes in the pH range 5-8, to determine the stability of the complexes in solution. Graphic abstract Six novel ruthenium(III) complexes with triazolopyrimidine derivatives demonstrated the potential for use as anticancer agents by maintaining the toxic effect on MCF-7 and HeLa cells.

Primary aromatic amines (PAAs), as a class of persistent and highly toxic organic pollutants, have been posing a great threat to human health and the environment. Therefore, the design and preparation of a highly sensitive and selective luminescent probe to detect PAAs among various amines are important but challenging. In this work, by introducing electron-deficient monomer 4,4 ‘-(benzo[c][1,2,5]thiadiazole-4,7-diyl)dibenzaldehyde (BTDD) with an aggregation-caused quenching behavior into the 2D framework, fluorescent ultrathin covalent triazine framework (F-CTF) nanosheets were constructed. Compared with the aggregated BTDD monomer, the obtained F-CTF-3 nanosheet shows much higher fluorescence quantum yield due to the BTDD fragment being well dispersed in the 2D framework. The F-CTF-3 nanosheet exhibits high stability, high porosity, and high fluorescence performance and has a rich electron-deficient unit in the pore channel, making it an ideal platform for sensing electron-rich PAA molecules. In fact, the F-CTF-3 nanosheet shows high sensitivity and selectivity for PAA detection by fluorescence quenching, among various amines, covering some classic aliphatic amines, heterocyclic amines, secondary aromatic amines and tertiary aromatic amines. To the best of our knowledge, it is the first reported fluorescent sensor for selective sensing of PAAs among various amines. Moreover, F-CTF-3 exhibits unprecedented low detection limits of 11.7 and 1.47 nM toward phenylamine (PA) andp-phenylenediamine (PDA), respectively, surpassing all the reported fluorescent sensors. The combination of experimental analysis and density functional theory (DFT) calculations demonstrates that the unique PAA detection performance of F-CTF-3 can be attributed to the static quenching process, which is confirmed by the formation of a ground-state fluorescence-quenched complex on account of the hydrogen bonding interactions between F-CTF-3 and PAAs. This work not only provides a thiadiazole-based 2D fluorescent organic framework nanosheet, but also an excellent fluorescent sensor with unexpected sensitivity and selectivity for PAA detection.

The construction materials that contacted with unsymmetrical dimethylhydrazine and the desorption solutions obtained when treating the contaminated surface of metals and alloys with water and reagents were studied by chromatography and mass spectrometry. Neutralization of unsymmetrical dimethylhydrazine was studied using ozone and shungite. Ozonation makes it possible to destroy the toxicant molecules chemically and physically adsorbed on the surface of metal constructions, due to which they can be reused and utilized. Shungite effectively adsorbs and catalytically decomposes not only unsymmetrical dimethylhydrazine and its transformation products, but also oligomer compounds formed during the storage of hydrazine fuel. Ozonation of spent shungite can increase the efficiency of destructive processes and completeness of its regeneration.
