Design and construction of Zn(II) coordination polymers made by pincer type pyridine-hydrazine based ligands

A new series of five zinc (II) coordination polymers, namely [Zn(L-I)(NO3)(OH2)](n) (1), [Zn(L-I)(CH3COO)](n) (2), [Zn(L-I)(NCS)](n) (3), [Zn(L-II)(CH3COO)](n) (4), and {[Zn-2(L-II)(2)(N-3)(2)] center dot H2O}(n) (5), has been self-assembled from different zinc (II) salts and pyridine-hydrazine ligands {HLI = 2-pyridinecarbaldehyde isonicotinoyl hydrazone, and HLII = 2-acetyl-pyridyl-isonicotinoylhydrazone} and has been structurally characterized. In all compounds, the ligand is singly-deprotonated and coordinates to the zinc center in the enolic form (=N-N=C-O-). In other words, the pyridine-hydrazine ligand acted as a tetradentate negatively charged chelating-bridging ligand and coordinated to the metal centers in N, N, O pincer mode and the Para-nitrogen of the pyridine ring coordinated to the zinc center of the adjacent unit. In compounds (1)-(4) the ancillary ligands act as terminal ligands and the zinc centers bridging by the pyridine-hydrazine building blocks formed one-dimensional 1D coordination polymers, whereas the azide N-3(-) anion in compound (5) further acted as a bridging agent and led to the formation of two-dimensional 2D network. A detailed analysis of Hirshfeld surfaces and fingerprint plots allows a comparison of intermolecular interactions in (1)-(5), which are crucial in building supramolecular architectures.

Mechanism for Zincophilic Sites on Zinc-Metal Anode Hosts in Aqueous Batteries

The zinc-metal anode (ZMA) is a critical component of rechargeable Zn-based batteries. Zinc-dendrite formation on ZMA during cycling causes an internal short-circuit, thereby limiting long-term practical operation of batteries. A strategy of introducing zincophilic sites shows promise in suppressing dendrite growth. However, the mechanism is not understood. Here, a detailed study of the mechanism of zincophilic sites based on multiple in situ/ex situ techniques is reported. Using a carbon-host as a model system with nitrogen sites as zincophilic sites and both ex situ near-edge X-ray absorption fine structure (NEXAFS) and in situ Raman spectra, it is shown that zinc ions are bonded with pyridine sites to form Zn-N bonds. The Zn-N bonds induce spacious nucleation of zinc on carbon-hosts and suppress zinc-dendrite formation. The host with zincophilic sites exhibits a homogenous Zn deposition, together with boosted electrochemical performance. This finding underscores the impact of nitrogen zincophilic sites in suppressing zinc-dendrite formation. It is shown that bonding between zinc ions and zincophilic sites is the mechanism for zincophilic nucleation in the ZMA host. These findings are expected to be of immediate benefit to researchers in battery technologies and materials science.

Design, synthesis and anti-inflammatory activity of imidazol-5-yl pyridine derivatives as p38 alpha/MAPK14 inhibitor

P38 alpha VMAPK14 is intracellular signalling regulator involved in biosynthesis of inflammatory mediator cytokines (TNF-alpha, IL-1, IL-6, and IL-1b), which induce the production of inflammatory proteins (iNOS, NF-kappa B, and COX-2). In this study, drug repurposing strategies were followed to repositioning of a series of B-RAF(V600E) imidazol-5-yl pyridine inhibitors to inhibit P38a kinase. A group 25 reported P38a kinase inhibitors were used to build a pharmacophore model for mapping the target compounds and proving their affinity for binding in P38a active site. Target compounds were evaluated for their potency against P38a kinase, compounds 1 la and 11d were the most potent inhibitors (IC50 = 47 nM and 45 nM, respectively). In addition, compound 11d effectively inhibited the production of pminflammatory cytokines TNF-alpha, 1L-6, and 1L-1 beta in LPS-induced RAW 264.7 macrophages with IC50 values of 78.03 mu M, 17.6 nM and 82.15 nM, respectively. The target compounds were tested for their anti-inflammatory activity by detecting the reduction of Nitric oxide (NO) and prostaglandin (PGE2) production in LPS-stimulated RAW 264.7 macrophages. Compound 11d exhibited satisfied inhibitory activity of the production of PGE2 and NO with IC(50 )values of 0.29 mu M and 0.61 mu M, respectively. Molecular dynamics simulations of the most potent inhibitor 11d were carried out to illustrate its conformational stability in the binding site of P38a kinase.

Influence of Bronsted and Lewis acidity of the modified Al-MCM-41 solid acid on cellulose conversion and 5-hydroxylmethylfurfuran selectivity

The modified Al-MCM-41 solid acids with turning Si/Al molar ratio were successfully fabricated through a hydrothermal route and utilized as a suitable catalyst in the cellulose conversion into 5-hydroxylmethylfurfural (5-HMF). The crystal structure, composition, morphologies and porosity of assynthesized acids were characterized by XRD, FT-IR, N-2 adsorption-desorption, TEM and EDS. The Al-27 MAS NMR and Si-29-MAS NMR results revealed the existence of both Al framework and Al extra framework. Besides, the existence of medium-weak and strong acid sites, according to Bronsted and Lewis acidity, in Al-MCM-41 acids was confirmed by NH3-TPD and FTIR-pyridine adsorption. The 30Al-MCM-41 solid acid (Si/Al molar ratio = 30) exhibited excellent activity with the highest 5-HMF yield of 40.56% compared to other samples. We also discovered that 5-HMF production, as well as cellulose conversion, strongly depended on the total acid, strong/medium-weak acid ratio, as well as Bronsted/Lewis acid ratio. Therefore, these parameters have been considered as essential factors for the design of solid acid for 5-HMF production. (C) 2020 Elsevier Ltd. All rights reserved.

Macrocyclic Metal Complexes Bearing Rigid Polyaromatic Ligands: Synthesis and Catalytic Activity

We synthesised palladium and platinum complexes possessing cyclic and acyclic pincer-type polyaromatic ligands and investigated their structural effect on the catalysis. The pincer-type bis(6-arylpyridin-2-yl)benzene skeleton was constructed via Krohnke pyridine synthesis under transition metal-free conditions on gram-scale quantity. Ligand structure significantly influenced catalytic activity toward the platinum-catalysed hydrosilylation of diphenyl acetylenes, despite the ligand-independence of the conformations and electronic properties of these complexes.

Orthoamides and Iminium Salts, IIICa. Further results about condensations reactions of orthoamides of alkyne carboxylic acids with CH2- and CH2/NH-acidic compounds

The 1,1-bis(dimethylamino)-1,3-butadienes (keten aminals) 11a-1 are prepared from orthoamide derivatives of alkyne carbonxylic acids 9b, d, e, i and CH2-acidic compounds 10a-c, f-h, k, o. The C-silylated orthoamide derivative 9c shows an ambivalent behaviour towards CH-acidic compounds. Reactions of 9c with strong CH2-acidic compounds like the nitro alkanes 10m, n and strongly enolized carbonyl compounds as methyl acetoacetate, cyanoacetamide, dibenzoylmethane, 1,3-dimethylbarbituric acid proceed under desilylation to give the ketene aminals 11u-z. In contrast to these reactions, the C-silylated ketene aminals 110-t are obtained from 9c and weaker CH2-acidic compounds as dimethyl malonate, cyanoacetic acid derivatives and benzylcyanides. CH/NH2-acidic compounds [cyanoacetamide (10d) and N-ethyl-cyanoacetamide (10f)] react with the orthoamide derivatives 9b, e-g at the acidic carbon-hydrogen bond to give the ketene aminals 11ac, ad, af, ag, ai, which cyclize to the pyridones 14a-d, d-g on heating. From the reaction of the orthoamide 9d with cyanoacetamide the pyridone 14c results directly. The persubstituted pyridone derivative 19 is formed by the reaction of cyanoacetamide with a mixture of the isomeric orthoamides 15 and 16. The 5,5-diamino-2,4-pentadienamide 11v attacks the orthoamide 9a at C3/C1. In the product 20 a cross conjugated multiple bond system is formed which contains an 1-aza-2,3-diamino function and a further ketene aminal function.

Synthesis of Arylidene – Isoquinolinones bearing Combretastatin Skeleton by Cyclocarbopalladation/cross coupling Tandem Heck-Suzuki Miaura Reactions using nano catalyst Pd@Py-IL-SPION

Cyclocarbopalladation/cross-coupling cascade intramolecular Heck-Suzuki-Miyaura reactions is applied for the first time by palladium immobilized on pyridine-imidazolium ionic liquid supported magnetic iron oxide nanoparticle catalyst (denoted Pd@Py-IL-SPION) for the last step to synthesize trisubstituted arylidene-isoquinolinones derivatives having Combretastatin skeleton. The reaction is performed via propargylamide intermediates prepared by Ugi 4-CR reactions, which undergoes intramolecular Heck-Suzuki-Miyaura domino reaction to produce the desired trisubstituted arylidene-isoquinolinones. The method shows full regio- and stereoselectivity derives from the particular Pd-catalyzed syn-insertion of triple bond.

Synthesis, Biological and Molecular Docking Study of Benzimidazole-Clubbed Tetrahydrothieno [3, 2-c] Pyridine as Platelet Inhibitors

Two novel series of tetrahydrothienopyridine clubbed benzimidazole hybrids were synthesized, characterized by spectral studies H-1 NMR, IR and mass analysis. Synthesized analogs were screened for in vitro antiplatelet activity. In addition, active analogs were further subjected in presence of proton pump inhibitors against standard prasugrel and aspirin to check minimization in antiplatelet activity. Active analogs 1-(2-(1-methyl-1H-benzo[d]imidazol-2-yl)-6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl)ethan-1-one (11) and (2-(1-(2-fluorobenzyl)-1H-benzo[d]imidazol-2-yl)-6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl)(3,4,5-trichlorophenyl)methanone (25) were significantly found more active than the standards in the presence of proton pump inhibitors. The structure and antiplatelet activity relationship was supported by molecular docking studies of active analogs to know how effectively, activity influenced by the merger of proton pump inhibitor precursor benzimidazole. The above studies successfully revealed that the synthesized analogs may found more active with further amendments via pharmacological point of view.

Transition-metal ion-mediated morphological transformation of pyridine-based peptide nanostructures

Inspired by natural metallopeptides, we have rationally designed two pyridine-conjugated short peptides. These two peptide conjugates formed a pair of constitutional isomers that helped us describe their structure-function relationship. Both the isomers consisted of an equal number of aromatic amino acid residues, but shuffling was observed in the position of two key amino acids, viz; tyrosine and phenylalanine, which brought a remarkable change in their self-assembling behavior. The presence of specific functional groups and chemical diversity in both conjugates made them very active towards metal coordination. Both the constitutional isomers adopted different pathways of self-assembly, which could be further controlled or transformed by the use of transition metal ions. Interestingly, it was observed that the metal ions could precisely control the morphology of these metallopeptide nanostructures and make them more stable. Therefore, such artificial metallopeptides possess remarkable advantages over the natural counterparts primarily due to their tailor-made chemical structures.

Application of 211915-84-3, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 211915-84-3 is helpful to your research.
