Investigating the Stabilizing Forces of Pentazolate Salts

Pentazolate (cyclo-N-5(-)) salts are actively pursued energetic nitrogen-rich compounds due to their potential as propellants and explosives. An in-depth understanding of the stabilizing forces between cyclo-N-5(-) anions and cations is important for designing cyclo-N-5(-) salts and achieving cyclo-N-5(-) salt conversions. Herein, the metathetical syntheses of cyclo-N-5(-) salts (compounds 1-4) containing heterocyclic amino-based cations 3,6-diguanidino-1,2,4,5-tetrazine, 1-guanyl-1,2,4-triazolium, 3,7-diamino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazol-2-ium, and 3,6,7-triamino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazol-2-ium are reported. In addition, an energetic cocrystal (compound 5) composed of compound 4 with 3,6,7-triamino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazole was synthesized using cocrystallization techniques. Crystal structures were investigated through geometrical and Hirshfeld analyses and theoretical calculations to reveal the contributions of hydrogen-bonding and pi-stacking interactions in stabilizing the pentazolate salts. Compounds 1-3 are stabilized by strong hydrogen-bonding interactions and weak pi-stacking interactions. The it-stacking interactions (cation-anion pi(+)-pi(-) contacts) are stronger in 4 and have an important role in promoting the stability of the salt. The binding energy of this pi-stacking interaction (-82.4 kcal mol(-1)) slightly surpasses that of the robust N6-H6A center dot center dot center dot N1 interaction (-75.1 kcal mol(-1)). For cocrystal 5, the spatial arrangement of its structural framework differs from that of its precursor, compound 4. The molecular stabilization energy, which increases from -75.1 to -94.3 kcal mol(-1) during the conversion of 4-5, primarily arises from strong pi-stacking interactions. Further observations indicate that cocrystal 5 has better thermal stability and detonation performance than 4, which establishes noncovalent modification via cocrystallization as an efficient method for forming multicomponent crystal systems and highlights the ability of coformers to modify energetic performance.

Tricyclic nitrogen-rich cation salts based on 1,2,3-triazole: Chemically stable and insensitive candidates for novel gas generant

A new tricyclic nitrogen-rich compound 4,5-bis(4,5-diamine-1,2,4-triazole-3-yl)-2H-1,2,3-triazole (2) was synthesized. Monovalent and divalent cations based on 1,2,3-triazole backbone were developed for energetic salts 3-13. It is worth mentioning that energetic salt 8 was obtained as a unique zwitterionic salt. These energetic compounds exhibit good thermal stability and positive heat of formation. Most of these newly synthesized compounds were insensitive to mechanical stimulation (IS >= 24 J, FS >= 252 N), while the sensitivity of compound 4 (IS = 7 J, FS = 120 N) is similar to that of RDX (IS = 7.4 J, FS = 120 N). Additionally, crystal analysis and theoretical calculations of crystals 2, 3, 4, 8 were carried to explore the relationship between strong hydrogen bonds and physicochemical properties. Furthermore, dinitramide salt 5 and zwitterionic salt 8 have relatively high theoretical detonation properties (5: D = 8770 m s(-1), 8: D = 8545 m s(-1)), which are close to RDX (D = 8795 m s(-1)). The compounds 2-5, 8 possess outstanding combustion performance (Pmax: 4.57-13.38 MPa) tested by constant-volume combustion experiments, which are superior to frequently-used gas generant guanidine nitrate. All the results demonstrate that dinitramide salt 5 and zwitterionic salt 8 with high volumes of detonation gas (5: 826.74 L kg(-1); 8: 799.77 L kg(-1)), moderate detonation performance and appropriate mechanical sensitivities (5: IS = 28 J, FS > 360 N; 8: IS > 40 J, FS > 360 N) may be useful as novel gas generant.

Anammox enrichment culture has unexpected capabilities to biotransform azole contaminants of emerging concern

Azoles are contaminants of emerging concern. They have a ubiquitous presence in the environment due to their wide variety of uses. This study investigated the fate of two commonly occurring azole compounds in an anammox enrichment culture. The results showed that 1H-pyrazole (PA) and 1H-1,2,4-triazole (TA) were biotransformed yielding major biotransformation products, 3-amino-1H-pyrazole and 3-amino-1H-1,2,4-triazole, respectively. Nitrate and glucose greatly stimulated the biotransformation. Under optimized conditions, 80.7% of PA and 16.4% of TA were biotransformed in an incubation period of 6 days. High molar product yield of 84.5% and 83.6% was observed per mole of PA and TA biotransformed, respectively. This novel and selective biotransformation constitutes the first report on the microbial biotransformation of PA and is amongst the very few reports on the biotransformation of TA. This study also provides evidence that anammox enrichments have unexpected capabilities to biotransform organic contaminants of emerging concern. (C) 2020 Elsevier Ltd. All rights reserved.

Synthesis and Biological Studies of O3-Aryl Galactosides as Galectin Inhibitors

beta-Galactose derivatives have recently been reported to selectively inhibit galectin-3, and a library of O3-arylated galactosides with varying substitution patterns was designed to study such inhibitions further. The O3-arylated galactosides were synthesized using diaryliodonium salts under mild and transition metal free conditions, providing the target products in moderate to good yields. An O3-trifluoroethylated galactoside was also synthesized using iodonium salt chemistry. Azido-substituted products were subsequently transformed into the corresponding triazoles. After deprotection, a selection of galactoside derivatives were evaluated for inhibitory potencies against galectins-1, 3, 4 N (N-terminal domain), 4 C (C-terminal domain), 7, 8 N, 8 C, 9 N, and 9 C and one compound with promising affinity and selectivity for both the N- and C-terminal domain of galectin-9 was discovered.

Investigation of Corrosion Inhibition Property of Triazole-Based Schiff Bases on Maraging Steel in Acid Mixtures

Triazole-based Schiff bases, 4-{[4-(dimethylamino)benzylidene]amino}-5-methyl-4H-1,2,4-triazole-3-thiol [DBAMTT] and 5-methyl-4-[(thiophene-2-ylmethylidene)amino]-4H-1,2,4-triazole-thiol [MTATT], were studied for their corrosion inhibitory action on maraging steel in the temperature range 30-45 degrees C in a 2:1 mixture of HCl and H2SO4. Both the inhibition efficiencies increased with temperature rise as well as the concentration of inhibitors. The anti-corrosion potential of these molecules was further validated by kinetic and thermodynamic analyses. Both DBAMTT and MTATT demonstrated inhibitory action of a mixed form by chemisorption on the metal surface obeying Langmuir isotherm adsorption. SEM-EDX analysis was conducted to confirm inhibitor adsorption onto the labeling steel surface. Experimental data indicated better corrosion inhibition property of MTATT over DBAMTT, whereas theoretical studies predict DBAMTT as a better inhibitor over MTATT. This may be due to the difference in the conditions of both studies: experimental studies carried out in acid solutions and theoretical studies in the gas phase. Different quantum chemical parameters were assessed using DFT calculations using the B3LYP/6-311++(d, p) basis set to gain insight into the relationship between the molecular structure and the efficiency of corrosion inhibition.

Synthesis, structures and magnetic properties of copper(II) complexes with 1,2,3-triazole derivate as ligand: a single-crystal-to-single-crystal transformation from mononuclear to polymeric complex of copper(II)

A new mononuclear complex Cu(tdp)Br-2 center dot MeCN (1, tdp = 2,2 ‘-(1H-1,2,3-triazole-1,4-diyl)dipyridine) has been synthesized, which can transform to a 1D coordination polymer [Cu(tdp)Br-2](n) (2) under ambient conditions through an irreversible single-crystal-to-single-crystal transformation process. The loss of lattice MeCN molecules in 1 was accompanied by the generation of new covalent bonds and an increase in dimensionality from 0 to 1D, leading to a change in magnetic exchange couplings between the adjacent Cu(II) ions. Magnetic susceptibility measurements indicate that 1 exhibits ferromagnetic interactions between the adjacent Cu(II) centers, while the intrachain magnetic interactions between Cu(II) ions are antiferromagnetic within 2.

Identification of 1,2,3-triazole-phthalimide derivatives as potential drugs against COVID-19: a virtual screening, docking and molecular dynamic study

In this work we aimed to perform an in silico predictive screening, docking and molecular dynamic study to identify 1,2,3-triazole-phthalimide derivatives as drug candidates against SARS-CoV-2. The in silico prediction of pharmacokinetic and toxicological properties of hundred one 1,2,3-triazole-phtalimide derivatives, obtained from SciFinderVR library, were investigated. Compounds that did not show good gastrointestinal absorption, violated the Lipinski’s rules, proved to be positive for the AMES test, and showed to be hepatotoxic or immunotoxic in our ADMET analysis, were filtered out of our study. The hit compounds were further subjected to molecular docking on SARS-CoV-2 target proteins. The ADMET analysis revealed that 43 derivatives violated the Lipinski’s rules and 51 other compounds showed to be positive for the toxicity test. Seven 1,2,3-triazole-phthalimide derivatives (A7, A8, B05, E35, E38, E39, and E40) were selected for molecular docking and MFCC-ab initio analysis. The results of molecular docking pointed the derivative E40 as a promising compound interacting with multiple target proteins of SARS-CoV-2. The complex E40-Mpro was found to have minimum binding energy of similar to 10.26 kcal/mol and a general energy balance, calculated by the quantum mechanical analysis, of similar to 8.63 eV. MD simulation and MMGBSA calculations confirmed that the derivatives E38 and E40 have high binding energies of similar to 63.47 +/- 3 and similar to 63.31 +/- 7 kcal/mol against SARS-CoV-2 main protease. In addition, the derivative E40 exhibited excellent interaction values and inhibitory potential against SARCov-2 main protease and viral nucleocapsid proteins, suggesting this derivative as a potent antiviral for the treatment and/or prophylaxis of COVID-19.

Novel Sigma 1 Receptor Antagonists as Potential Therapeutics for Pain Management

The sigma 1 receptor (S1R) is a molecular chaperone protein located in the endoplasmic reticulum and plasma membranes and has been shown to play important roles in various pathological disorders including pain and, as recently discovered, COVID-19. Employing structure- and QSAR-based drug design strategies, we rationally designed, synthesized, and biologically evaluated a series of novel triazole-based SIR antagonists. Compound 10 exhibited potent binding affinity for S1R, high selectivity over S2R and 87 other human targets, acceptable in vitro metabolic stability, slow clearance in liver microsomes, and excellent blood-brain barrier permeability in rats. Further in vivo studies in rats showed that 10 exhibited negligible acute toxicity in the rotarod test and statistically significant analgesic effects in the formalin test for acute inflammatory pain and paclitaxel-induced neuropathic pain models during cancer chemotherapy. These encouraging results promote further development of our triazole-based S1R antagonists as novel treatments for pain of different etiologies.
