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.

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.

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.

Heterobimetallic Carbene Complexes Bearing Cyclometalated Ir-III/Rh-III and Mixed NHC boolean AND Py/PPh3 Coordinated Pd-II Centers: Structures and Tandem Catalysis

Heterobimetallic complexes bearing NHC donor ligands are gaining immense popularity in organometallic chemistry and tandem catalysis. It is known that the NHC reacts with Pd-II in the presence of pyridine to yield PEPPSI type complexes and the NHC ligands having ortho-C-H proton easily orthometalate to Ir-III or Rh-III centers. Combining these two methodologies in a stepwise fashion, we present here a series of heterobimetallic Ir-III-Pd-II and Rh-III-Pd-II complexes from a dicarbene donor ligand featuring cyclometalated Ir-III or Rh-III and mixed NHC perpendicular to Py /PPh3 coordinated Pd-II centers. All the heterobimetallic complexes have been structurally characterized by X-ray crystallographic analysis. The heterobimetallic complexes featuring mixed NHC perpendicular to PPh3 coordinated Pd-II centers show better activity in tandem Suzuki-Miyaura/transfer hydrogenation reactions compared to both, the heterobimetallic complexes possessing PEPPSI type Pd(II)centers, and the equimolar mixture of their mononuclear Pd-II and Rh-III or Ir-III counterparts. The heterobimetallic complex featuring cyclometalated Ir-III and mixed NHC perpendicular to PPh3 coordinated Pd-II center shows excellent selectivity for 4-biphenylmethanol (isolated yield: 92 %) in tandem catalysis.

Pyridinyl-triazole ligand systems for highly efficient CuI-catalyzed azide- alkyne cycloaddition

Pyridinyl-triazole ligand systems (including N-2-2-pyridinyl 1,2,3-triazoles and N-1/N-2-substituted 2-(NH-1,2,3triazol-4-yl)pyridines) were found to be superior ligands for CuI-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. Low catalyst loadings, short reaction times, facile catalyst recyclability, ambient temperature, and open-flask conditions made this catalytic system very practical. The iodide anions could form iodine bridges to construct stable dinuclear Cu(I) complexes with these ligands, which was the key to achieve high catalytic activities. While CuBr and CuCl were not suitable for this ligand system because of the improper size of Br and Cl atoms for the formation of the corresponding dinuclear Cu(I) complexes.

Electrosynthesis of silver metal nanocomposites in a copolymer matrix of 1-vinyl-1,2,4-triazole and acrylic acid

Nanocomposites and silver nanocomposite coatings based on a copolymer of 1-vinyl-1,2,4-triazole and acrylic acid were synthesized in an aqueous and aqueous-ethanol medium on pure iron and steel electrodes by the electrochemical method. The composition and structure of nanocomposites is confirmed by UV, IR spectroscopy, X-ray diffraction analysis, transmission electron microscopy, thermogravimetric method, etc. It was found that the solubility of nanocomposites depends on the concentration of silver particles in the (co) polymer matrix. Stage by stage thermal decomposition of nanocomposites takes place.

Design and In Silico Study of the Novel Small Molecular MDM2 Inhibitors

Protein-protein Interaction (PPIs) plays a central role in many diseased conditions. Therefore to target and to modulate PPIs is an efficient approach for the disease treatment. Cancer is also arising because of Protein-protein interaction. In cancer, the tumor suppressor p53 protein got inhibited by the MDM2 protein. p53 protein regulates the cell cycle and apoptosis. Interaction between the p53-MDM2 proteins is responsible for the inhibition of the p53 function. By this interaction, MDM2 degrades and inhibits the p53 protein. Hence, to target and inhibit the p53-MDM2 interaction for the treatment of cancer is the rational approach. By targeting this interaction with the drugs, we can selectively kill the cancer cells over the normal cells. Recently, p53-MDM2 interaction inhibitor drugs have been reported by many researchers and pharmaceutical companies. And several drugs entered into the clinical trials. In this study, a novel 1,2,4-triazole based molecules were designed as MDM2 inhibitors and performed their in-silico study. We designed the novel compound 01 and Lead 1a. In this work, In silico study of the Lead 1a and reference compounds (Nutlin 3a, RG7112) was carried out. The molecular docking study of the Novel 1,2,4-triazole based lead 1a and reference compounds was carried out. The docking score of the Lead 1a found to be better than Nutlin 3a and close to RG7112. The various possible conformations and binding affinity values were also determined by the docking study. These results indicate the Lead 1a as a potential MDM2 inhibitor and anti-cancer agent.

Iridium-Catalyzed Direct Amidation of Imidazoles at the C-2 Position with Isocyanates in the Presence of Hydrosilanes Leading to Imidazole-2-Carboxamides

Regioselective coupling reaction of N-substituted imidazoles with isocyanates in the presence of a stoichiometric amount of hydrosilanes catalyzed by Ir-4(CO)(12) to give imidazole-2-carboxamides is reported. Imidazoles bearing an (O-silyl)carboximidate group at the 2-position appear to be initially formed in the reaction; these are then hydrolyzed to the final products in situ. The addition of the hydrosilane was essential for the catalytic reaction to proceed. Substituents on the imidazole ring had no effect on the reaction, except for certain bulky substituents such as tBu and Ph groups at the 4-position. Triazoles such as 4-methyl-4H-1,2,4-triazole and 1-methyl-1H-1,2,4-triazole were also applicable to this C-H amidation, and the latter reaction proceeded regioselectively at the carbon atom between the sp(3) and sp(2) nitrogen atoms of the ring, and not between the two sp(2) nitrogen atoms.

G-quadruplex-based aptamers targeting human thrombin: Discovery, chemical modifications and antithrombotic effects

First studies on thrombin-inhibiting DNA aptamers were reported in 1992, and since then a large number of anticoagulant aptamers has been discovered. TBA – also named HD1, a 15-mer G-quadruplex (G4)-forming oligonucleotide – is the best characterized thrombin binding aptamer, able to specifically recognize the protein exosite I, thus inhibiting the conversion of soluble fibrinogen into insoluble fibrin strands. Unmodified nucleic acid-based aptamers, in general, and TBA in particular, exhibit limited pharmacokinetic properties and are rapidly degraded in vivo by nucleases. In order to improve the biological performance of aptamers, a widely investigated strategy is the introduction of chemical modifications in their backbone at the level of the nucleobases, sugar moieties or phosphodiester linkages. Besides TBA, also other thrombin binding aptamers, able to adopt a well-defined G4 structure, e.g. mixed duplex/quadruplex sequences, as well as homoand hetero-bivalent constructs, have been identified and optimized. Considering the growing need of new efficient anticoagulant agents associated with the strong therapeutic potential of these thrombin inhibitors, the research on thrombin binding aptamers is still a very hot and intriguing field. Herein, we comprehensively described the state-of-the-art knowledge on the DNA-based aptamers targeting thrombin, especially focusing on the optimized analogues obtained by chemically modifying the oligonucleotide backbone, and their biological performances in therapeutic applications.
