Visible Light-Induced [3+2] Cyclization Reactions of Hydrazones with Hypervalent Iodine Diazo Reagents for the Synthesis of 1-Amino-1,2,3-Triazoles

In this study, visible-light-induced [3+2] cyclization reactions of hydrazones with hypervalent iodine diazo reagents as diazomethyl radical precursors are reported. Mild reaction conditions, a broad substrate scope, and excellent functional group compatibility were observed. Furthermore, the synthetic utility was demonstrated by gram-scale synthesis and elaboration to several value-added products. This protocol broadens the scope of diazo chemistry, and is applicable to the late-stage functionalization of natural products.

Tripodal structured blue-green emissive fluorescent sensors for highly selective bifunctional detection: Their logic gate operations and real sample applications

The three novel tripodal-structured polyaromatic hydrocarbon-based fluorescent sensors which contain triazole as binding sites and naphthalene, anthracene, pyrene moieties as fluorophores (TN, TA, and TP) were synthesized via click chemistry and fully characterized by standard spectroscopic techniques. The photophysical and fluorescent sensor properties of TN, TA, and TP were investigated by UV-Vis electronic absorption, steady-state/time resolved/3-D fluorescence, and EEM-analysis spectroscopies. It was found that fluorescent sensors demonstrated excellent sensitivity and selectivity for Fe3+ ions over-tested other metal ions with significant fluorescence turn-off’ responses which led to instant naked-eye and fluorescence color change. The binding mechanisms of TN, TA, and TP for F were evaluated with Job’s plot and mass analysis. Moreover, treatment with H led to a sharp be increased in fluorescence intensities of TN, TA, and TP with turn-on fluorescence responses of Fe complexes ensembles. The obtained LODs (0.25-0.74 mu M) for iron ions were significantly lower than the tolerated limit of iron for drinking water by WHO/US EPA. The highly selective, time-saving, and sensitive fluorescence turn-off’ responses of fluorescent sensors for Fe3+ ions were used for iron determination in environmental water samples. In addition, reversible fluorescence quenching responses of presented fluorescent sensors after addition of H were utilized for improvement of IMPLICATION logic gates.

Design, synthesis, DNA binding, modeling, anticancer studies and DFT calculations of Schiff bases tethering benzothiazole-1,2,3-triazole conjugates

In an attempt to design and prepare a new library of anticancer candidates, focused thiopropargylated benzothiazole was reacted with ethyl azidoacetate and/or ethyl azidobenzoate to yield newer 1,2,3-triazole-benzothiazole conjugates bearing ester functionality through click chemistry approach. The hydrazinolysis of the obtained ester-based triazoles was also carried out to give the corresponding 1,2,3-triazole acid hydrazide derivatives as precursors for the synthesis of the focused Schiff bases by their condensation with various benzaldehyde derivatives. Spectroscopic study was investigated on the establishment of the structures of all newly synthesized Schiff bases bearing benzothiazole-1,2,3-triazole molecular conjugate. The newly designed hydrazones showed two isomers ( cis-E and trans-E ) with different isomeric distribution as confirmed by NMR spectral data and supported by DFT carried out in gas phase at B3LYP 6-311G (d,p) basis set. The DFT results showed that the cis-E isomer is the lower energy structure and this finding was illustrated in terms of the intermolecular H-bonding. These molecules were screened for anticancer activities with A549 and H1299 lung cancer cell lines. The anticancer activities ranged from 55 to 90%. DNA binding study was also carried out to see the mechanism of action and the DNA binding constants were of good value ranging from of 2.0 x 10(5) and 14.7 x 10(5) M-1; indicating good interactions of the reported molecules with DNA. Finally, the modeling was confirmed and it was found that the results of modeling were in good agreement with the results of anticancer and DNA binding studies. All these finding confirmed that the reported molecules work as anticancer agents by interacting with DNA. (C) 2020 Published by Elsevier B.V.

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 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.

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.

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.

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.

Design, synthesis and biological activity of 1,4-quinone moiety attached to betulin derivatives as potent DT-diaphorase substrate

In this research, betulin derivatives were bonded to the 1,4-quinone fragment by triazole linker. Furthermore, the enzymatic assay used has shown that these compounds are a good DT-diaphorase (NQO1) substrates as evidenced by increasing enzymatic conversion rates relative to that of streptonigrin. The anticancer activities of the hybrids were tested against a panel of human cell lines, like: melanoma, ovarian, breast, colon, and lung cancers. The structure-activity relationship showed that the activity depends on the type of 1,4-quinone moiety and the tumor cell lines used. It was also found that the anticancer effects were increasing against the cell line with higher NQO1 protein level, like: breast (T47D, MCF-7), colon (Caco-2), and lung (A549) cancers. The transcriptional activity of the gene encoding a proliferation marker (H3 histone), cell cycle regulators (p53 and p21) and apoptosis pathway (BCL-2 and BAX) for selected compounds were determined. The molecular docking study was carried out to examine the interaction between the hybrids and NQO1 enzyme. The computational simulation showed that the type of the 1,4-quinone moiety influences location of the compound in the active site of the enzyme. It is worth noting that the study of new hybrids of betulin as substrate for NQO1 protein may lead to new medical therapeutic applications in the future.

Exploring the chemical space of 1,2,3-triazolyl triclosan analogs for discovery of new antileishmanial chemotherapeutic agents

Triclosan and isoniazid are known antitubercular compounds that have proven to be also active against Leishmania parasites. On these grounds, a collection of 37 diverse 1,2,3-triazoles based on the antitubercular molecules triclosan and 5-octyl-2-phenoxyphenol (8PP) were designed in search of novel structures with leishmanicidal activity and prepared using different alkynes and azides. The 37 compounds were assayed against Leishmania donovani, the etiological agent of leishmaniasis, yielding some analogs with activity at micromolar concentrations and against M. tuberculosis H37Rv resulting in scarce active compounds with an MIC of 20 mu M. To study the mechanism of action of these catechols, we analyzed the inhibition activity of the library on the M. tuberculosis enoyl-ACP reductase (ENR) InhA, obtaining poor inhibition of the enzyme. The cytotoxicity against Vero cells was also tested, resulting in none of the compounds being cytotoxic at concentrations of up to 20 mu M. Derivative 5f could be considered a valuable starting point for future antileishmanial drug development. The validation of a putative leishmanial InhA orthologue as a therapeutic target needs to be further investigated.
