Dual-Cationic Poly(ionic liquid)s Carrying 1,2,4-Triazolium and Imidazolium Moieties: Synthesis and Formation of a Single-Component Porous Membrane

Both imidazolium and 1,2,4-triazolium cations are important functional moieties widely incorporated as building blocks in poly(ionic liquid)s (PILs). In a classical model, a PIL usually contains either imidazolium or 1,2,4-triazolium in its repeating unit. Herein, via exploiting the slight reactivity difference of alkyl bromide with imidazole and 1,2,4-triazole at room temperature, we synthesized dual-cationic PIL homopolymers carrying both imidazolium and 1,2,4-triazolium moieties in the same repeating unit, that is, an asymmetrically dicationic unit. We investigated their fundamental properties, for example, thermal stability and solubility, as well as their unique function in forming supramolecular porous membranes via a water-initiated phase-separation and cross-linking process. With such knowledge, we identified a water-based fabricate strategy toward air-stable porous membranes from single-component Pits. This study will enrich the design tools and chemical structure library of PILs and expand their application spectrum.

An updated research of glycogen synthase kinase-3 beta inhibitors: a review

Glycogen synthase kinase-3 beta (GSK-3 beta) is a highly conserved multifunctional serine/threonine (Ser/Thr) protein kinase widely expressed in many tissues. GSK-3 beta inhibitors could be used in the treatment of human key diseases, such as cancer, Alzheimer’s disease, Parkinson’s disease, inflammation, type-II diabetes, and so on, due to the multi-role of GSK-3 beta in the hepatic glycolysis regulation, cell signaling pathways, and phosphorylation of various proteins. Recently, sets of diverse GSK-3 beta inhibitors have been prepared, and biologically evaluated in vitro and in vivo in different screening models. This review summarizes the latest developments in GSK-3 beta inhibitors unclosed from 2015 to 2019, including their structure-activity relationship and bioactivity studies.

Regioselective synthesis and DFT computational studies of novel beta-hydroxy-1,4-disubstituted-1,2,3-triazole-based benzodiazepinediones using click cycloaddition reaction

Novel beta-hydroxy-1,4-disubstituted-1,2,3-triazole-based benzodiazepinedione derivatives were synthesized by a regioselective cascade reaction and were fully characterized by HRMS, FT-IR, H-1 NMR, and C-13 NMR measurements. The cascade reaction consists of the azidation of epoxides and the Huisgen [3+2] dipolar cycloaddition of the resulted beta-hydroxy azides with the N,N ‘-dipropargyl benzodiazepine to give the wished 1,2,3-triazole-based benzodiazepinedione derivatives. Good yields (60-85%), easily available and inexpensive starting materials, using water as a green solvent, and avoiding the handling of organic azides as they are generated in situ are the advantages of this method. Theoretical calculations were also conducted by the DFT method using the B3LYP functional and 6-31+G(d,p) basis set on structure to characterize structure 3a. For structural and electronic characterization, H-1 and C-13 chemical shifts were calculated by the computational method and interpreted. The DFT calculated data were in line with the experimental data.

Zinc-based triazole metal complexes for efficient iodine adsorption in water

Radioactive iodine is extremely harmful to the environment, and it is of great significance to develop materials that efficiently remove iodine. We prepared two triazole metal complexes with simple method, denoted as Zn(tr)(OAc) and Zn(ttr)(OAc), which were used to adsorb iodine from aqueous solution. The properties and adsorption mechanism of the two materials were studied by different techniques including XRD, SEM, N-2 porosimetry at 77 K, FTIR, TGA, elemental analysis (EDS), and X-ray photoelectron spectroscopy (XPS). The results showed that both materials had good water and thermal stability. Pseudo-second-order kinetic model was better at describing the iodine adsorption kinetics onto the adsorbents. It was proved that chemical adsorption dominated, iodine mainly enriched on the materials in the form of I-3(-1). Zn(ttr)(OAc) had a higher adsorption capacity than Zn(tr)(OAc) due to the electron-donating group -NH2. The maximum adsorption capacity of the two materials for iodine reached 714.501 mg center dot g(-1) and 846.108 mg center dot g(-1) at 25 degrees C.

Phenyl(triazolyl)carbene revisited: Unique role of triazolyl group on carbene chemistry

The chemistry of (1,4-diphenyl-1H-1,2,3-triazol-5-yl)(phenyl)carbenes (1T), originally reported by Smith et al., was reinvestigated by using modern spectroscopic methods as well as density functional theory (DFT) calculations, and the results were compared with that observed for analogous diphenylcarbene (1H) to clarify the role of triazole group in diarylcarbene chemistry. Product analysis indicated that 1T gave two intramolecular cyclization products (2 and 3) formed as a result of a formal attack of carbene on the phenyl rings at 1- and 4-positions of the triazole ring. The results were closely similar to that observed for 1H. The behaviors of triplet carbene (3)1T were directly monitored not only by electron spin resonance (ESR) and UV-Vis spectroscopic methods in rigid matrix at low temperature but also by laser flash photolysis in solution at room temperature and compared with those observed for (3)1H. Whereas the lifetime of (3)1T was some 2 orders of magnitude longer than that of (3)1H, the reactivity of (3)1T toward typical triplet trapping reagents was greater than that of (3)1H. In order to elucidate these rather conflicting observations, geometries and relative energies of carbenes 1T and 1H as well as species involved in the reactions leading to the final products were calculated by the DFT method. The results are interpreted as indicating that (3)1H decays by participating in the reaction of upper-lying (1)1H much more easily than (3)1T. The difference in the reactivity toward external trapping reagents is explicable by taking into account the difference in steric crowdedness around carbene center between the two.

Hierarchical Spin-Crossover Cooperativity in Hybrid 1D Chains of Fe-II-1,2,4-Triazole Trimers Linked by [Au(CN)(2)](-) Bridges

Foremost, practical applications of spin-crossover (SCO) materials require control of the nature of the spin-state coupling. In existing SCO materials, there is a single, well-defined dimensionality relevant to the switching behavior. A new material, consisting of 1,2,4-triazole-based trimers coordinated into 1D chains by [Au(CN)(2)](-) and spaced by anions and exchangeable guests, underwent SCO defined by elastic coupling across multiple dimensional hierarchies. Detailed structural, vibrational, and theoretical studies conclusively confirmed that intra-trimer coupling was an order of magnitude greater than the intramolecular coupling, which was an order of magnitude greater than intermolecular coupling. As such, a clear hierarchy on the nature of elastic coupling in SCO materials was ascertained for the first time, which is a necessary step for the technological development of molecular switching materials.

Regioselective Synthesis of Novel [1,2,4]Triazolo[1,5-a]pyridine Derivatives

Herein we report the reaction of 2-(5-aryl-4H-1,2,4-triazol-3-yl)acetonitriles 1 a,b with appropriate Michael acceptors 2-4 to give novel [1,2,4]triazolo[1,5-a]pyridines 5-8, whose antioxidant properties have been investigated. A plausible reaction mechanism, supported by DFT calculations, has been proposed to explain the total observed regioselective formation of [1,2,4]triazolo[1,5-a]pyridine derivatives depending on the type of substituents on the Michael acceptor. Triazoles are well-known agents exhibiting antimicrobial,([1]) antitumor,([2]) anti-inflammatory,([3]) antihypertensive,([4]) anticonvulsant,([5]) antiviral([6]) and analgesic([7]) biological activities. On the other hand, pyridine is the key core of heterocyclic derivatives showing a variety of pharmacological properties.([8-12]) Several studies have revealed that a combination of different bioactive molecules, having different mechanisms of action, is a current strategy affording useful therapeutic agents.([13]) This is the case of the [1,2,4]triazolo[1,5-a] pyridine heterocyclic motif,([14]) present in a number of bioactive compounds,([15]) and largely used in materials chemistry.([16]) Accordingly, diverse synthetic methods have been described for the synthesis of differently substituted [1,2,4]triazolo[1,5-a]pyridines.([17-24]) Our group has recently reported the ultrasound-promoted facile and convenient one-pot procedure for the synthesis of novel [1,2,4]triazolo[1,5-a]pyridines in short reaction times and high yields, based on the reaction of 2-(5-aryl-4H-1,2,4-triazol-3-yl)acetonitriles, malononitrile (or ethyl cyanoacetate) and aromatic aldehydes, in absolute ethanol, in the presence of IRA-400.([25])

Design, click conventional and microwave syntheses, DNA binding, docking and anticancer studies of benzotriazole-1,2,3-triazole molecular hybrids with different pharmacophores

Despite the availability of some drugs, there is an urgent need for effective anti-cancer medication. It is due to various side effects and non-functionality of the present drugs; especially at the late stage of cancer. Therefore, three series ( 4a-e, 6a-e and 8a-j; 21 compounds) of benzotriazole-1,2,3-triazole hybrids (carrying different pharmacophores) have been designed and synthesized (by both conventional and microwave syntheses) through the Cu(I)-catalyzed click 1,3-dipolar cycloaddition reaction of the propargylated benzotriazole with the appropriate aliphatic, aromatic and phenyl/benzyl acetamide azides. The syntheses times were from 6 to 12 h and 4 to 8 min in conventional and microwave syntheses. The yields were 80 to 86% and 89 to 95% in conventional and microwave syntheses; confirming microwave synthesis as an economic and eco-friendly method. These compounds were characterized by proper spectroscopic methods. The anticancer activities with A549 and H1299 lung cancer cell lines were in the range of 70.0 to 90.0% for 4a-e series, 78.0 to 90.0% for 6a-e series and 81.0 to 90.0% for 8a-j series. The reported compounds showed good DNA binding constants in the range of 1.3 x 10(3) to 11.90 x 10(5) M-1. The docking results suggested strong DNA bindings of the reported compounds in the minor grooves of DNA; through hydrogen bonding and hydrophobic interactions. The quite good anticancer activities and high DNA binding constants have indicated that the reported molecules may be future anticancer agents. (c) 2020 Elsevier B.V. All rights reserved.

In silico design of a new Zn-triazole based metal-organic framework for CO2 and H2O adsorption

In search for future good adsorbents for CO2 capture, a nitrogen-rich triazole-type Metal-Organic Framework (MOF) is proposed based on the rational design and theoretical molecular simulations. The structure of the proposed MOF, named Zinc Triazolate based Framework (ZTF), is obtained by replacing the amine-organic linker of MAF-66 by a triazole, and its structural parameters are deduced. We used grand-canonical Monte Carlo (GCMC) simulations based on generic classical force fields to correctly predict the adsorption isotherms of CO2 and H2O. For water adsorption in MAF-66 and ZTF, simulations revealed that the strong hydrogen bonding interactions of water with the N atoms of triazole rings of the frameworks are the main driving forces for the high adsorption uptake of water. We also show that the proposed ZTF porous material exhibits exceptional high CO2 uptake capacity at low pressure, better than MAF-66. Moreover, the nature of the interactions between CO2 and the MAF-66 and ZTF surface cavities was examined at the microscopic level. Computations show that the interactions occur at two different sites, consisting of Lewis acid-Lewis base interactions and hydrogen bonding, together with obvious electrostatic interactions. In addition, we investigated the influence of the presence of H2O molecules on the CO2 adsorption on the ZTF MOF. GCMC simulations reveal that the addition of H2O molecules leads to an enhancement of the CO2 adsorption at very low pressures but a reduction of this CO2 adsorption at higher pressures.
