In this work, new sulfonylhydrazone compounds with alkyl derivatives (SH1- SH4 series) were synthesized via a green chem. method, and their inhibition effects on acetylcholinesterase and butyrylcholinesterase (AChE, BChE) were determined in vitro. This work was designed in two stages; in the first stage, using compounds that contain both sulfonamide and hydrazine groups which have important pharmacol. properties, a series of sulfonyl hydrazone with alkyl derivatives (SH1- SH4) were synthesized with a method that is less time-consuming and more environmentalist that was by using different substitute groups containing aldehyde and ketone compounds The structures of the synthesized compounds were characterized by elemental analyses, 1H NMR, 13C NMR, FT-IR methods. In the second stage, the effects of the synthesized sulfonyl hydrazones with alkyl derivatives on acetylcholinesterase and butyrylcholinesterase enzymes were examined According to the results, all the synthesized compounds inhibited AChE and BChE enzymes. When the IC50 values were compared, SH2-3 (IC50 = 5.27 ± 0.05 μM) and SH3-3 (IC50 = 12.29 ± 1.47 μM) compounds which are containing the Bu group have the best inhibition effect on the AChE enzyme and BChE enzyme, resp. In addition, the predictive properties of all compounds in terms of drug similarity were scanned using five Lipinski rules and ADME estimations In silico ADME studies play an important role in improving and predicting drug compounds In the ADME study; The absorption, distribution, metabolism, elimination, and properties of the mols. given below were theor. calculated Also, to evaluate the binding interactions between the sulfonylhydrazone compounds and enzymes, mol. docking studies were performed and the compounds with the best inhibition effect SH2-3 (for AChE enzyme) and SH3-3 (for BChE enzyme) were tested. Both in vitro and silico the results showed that two compounds could act as potent inhibitors of AChE, BChE. The results came from multiple reactions, including the reaction of 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Reference of 2-Hydroxy-4-methoxybenzaldehyde)

The title of the article was 《The Aryl Sulfide Synthesis via Sulfide Transfer》.Application of 2398-37-0 The author mentioned the following in the article:

Aryl sulfides are in great demands in drugs and materials sciences. To avoid using nucleophilic and noxious thiols, many efforts have been focused on exploring novel sulfide resources. Herein, a reductive Pd-catalyzed, Ni-mediated method to synthesize aryl sulfides via a sulfide transfer reaction is developed. The utility and scope of this reaction is exemplified by various aryl electrophiles and aryl sulfides. Mechanistic studies reveal two competing catalytic cycles of sulfide transfer and aryl transfer in this reaction, where the former one is favored over the later one because of the large energy barrier difference during the transmetalation. Moreover, two important chems. are late-stage functionalized by this method, exhibiting the potential applications in drugs and materials science. In the experiment, the researchers used many compounds, for example, 1-Bromo-3-methoxybenzene(cas: 2398-37-0Application of 2398-37-0)

In a two-steps synthetic route, bis(enaminone) was used to prepare a novel bis(3-amino-1H-pyrazolo[3,4-b]pyridine). Next, the former hybrid was reacted with two equivalent of the appropriate enaminones as well as arylidinemalononitriles in pyridine under microwave irradiation at 120° for 2 h to afford the target bis(pyrimidines). Furthermore, a mixture of bis(pyrazolopyridine) reacted with two equivalent of 1,3-diketones and β-ketoesters in glacial acetic acid was microwave irradiated at 130° for 90 min to give bis(2,4-disubstituted pyrimidines) and bis(2-substituted pyrimidin-4(1H)-ones), resp.

In recent years, acrylate binders were widely used in PBX production High loading of explosives and processability are the prominent features of these binders that researchers are trying to improve the energetic properties of these binders. In this research, a novel energetic binder of poly (2,4,6-trinitrophenylacetal acrylate) (PATNP) was synthesized through acetalization reaction Poly(glycerol monoacrylate) with 2,4,6-trinitrophenyl acetaldehyde in the presence of p-toluene sulfonic acid (PTSA) as the catalyst. The polymer structure was confirmed using 1H NMR and FT-IR. Thermal anal. obtained from the TGA curve of polymer shows that the addition of TNT derivatives significantly changes the thermal decomposition processes. In the TGA curve of PATNP, two main weight losses were observed with a decomposition percentage of 38 and 37%. The glass transition temperatures (Tg) of poly(glycerol monoacrylate) and PATNP were measured by DSC, and their Tg were obtained at -51° and -43°, resp. The heat of formation (HOF) and the HOMO-LUMO gap of PATNP was calculated using DFT computational method and compared with HTPB, AHTPB, and GAP binders. The HOF of PATNP for the monomer and dimer was obtained as 70.67 and 263.26 J/g, resp. The HOMO-LUMO gap for TNPA and PATNP was calculated at 3.7296 and 4.152 eV, resp.

A protocol to synthesize trisubstituted alkenyl thioethers I (R1 = Ph, 3-ClC6H4, 2-naphthyl, 2-thienyl, etc.; R2 = i-Pr, cyclohexyl, PhCH2, PhCMe2, etc.) through a direct S-alkylation of 1,2,3-thiadiazoles II with C-radical precursors, 4-alkyl-1,4-dihydropyridines III (R3 = EtO2C, t-BuO2C, CN), driven by visible-light photocatalysis is disclosed. A broad range of primary, secondary and tertiary C-radical precursors is suitable for this reaction and the desired products can be obtained in good to excellent yields under mild conditions. Remarkably, high stereoselectivity with Z-alkenyl thioethers was achieved in the presence of a Cu(OAc)2 catalyst. Synergistic exptl. and computational studies were carried out to shed light on the mechanisms of this reaction, in which the quenching pathway of an excited photocatalyst (*RuII) could be altered in the presence of the Cu(OAc)2 catalyst. A reductive quenching pathway (RuII/*RuII/RuI/RuII) was proposed in the absence of the Cu(OAc)2 catalyst while an oxidative quenching pathway (RuII/*RuII/RuIII/RuII) was suggested with the assistance of the Cu(OAc)2 catalyst. In addition, the origin of the Z-selectivity of the product was discussed.

The article was titled 《Coordination polymers based on rhenium octahedral chalcocyanide cluster [Re6Se8(CN)6]4- and lanthanide ions solvated with dimethylformamide》.Category: ethers-buliding-blocks The article contains the following contents:

The authors demonstrate influence of the source of organic ligand on the formation of supramol. structures based on the octahedral metal clusters. Two series of coordination polymers based on the rhenium clusters [Re6Se8(CN)6]4- and Ln3+ complexes (Ln = Sm, Eu, Tb, Dy) with DMF were obtained. The first series was obtained by direct addition of DMF in the reaction mixture The series consist of the compounds crystallizing in trigonal crystal system, R3c space group, and possessing a framework porous structures composed of cluster anions and [Ln(DMF)3(H2O)2]3+ complexes. Compounds of the second series were obtained as a result of in situ generation of DMF by hydrolysis of N,N-dimethylformamide di-Me acetal (DMF DMA). These compounds were crystallized in orthorhombic crystal system, Pnma space group, and possessed a layered structure consisting of cluster anions and [Ln(DMF)2(H2O)2]3+ complexes. The difference in the structures formed depends on the source of DMF rather than other reaction conditions.
