Inverse vulcanization offers a new method to make value to this cheap and highly abundant sulfur to produce sulfur-based polymers for different applications. However, most of the research done so far dealt with the characterization of the polymers or their efficiency in certain applications. Here, 4-vinylbenzyl chloride (VBC) is reacted with sulfur under optimized reaction conditions to produce linear sulfur-based polymer. Response Surface Methodol. (RSM) is employed to optimize the reaction conditions in terms of reaction temperature, reaction time, and initial sulfur content. The properties of the polymer produced under optimized conditions are then evaluated using proton NMR (1H NMR), CHNS elemental anal., thermogravimetric anal. (TGA), differential scanning calorimetry (DSC), Fourier transform IR spectroscopy (FTIR), powder X-Ray diffraction (PXRD), and field emission SEM (FESEM). The formation of the polymer and full conversion of the monomers were confirmed by NMR and CHNS anal. The S/VBC polymer showed a uniform morphol. and smooth surface. The polymer demonstrated an amorphous structure with a low Tg (3.7°C), high thermal stability (205°C), and great stability against depolymerization by time. The S/VBC polymer is significant due to its ability for post-functionalization which makes it possible to introduce new applications to sulfur-based polymers.

By following a multitarget ligand design approach, a library of 47 compounds was prepared, and they were tested as binders of selected G protein-coupled receptors (GPCRs) and inhibitors of acetyl and/or butyryl cholinesterase. The newly designed ligands feature pyridazinone-based tricyclic scaffolds connected through alkyl chains of variable length to proper amine moieties (e.g., substituted piperazines or piperidines) for GPCR and cholinesterase (ChE) mol. recognition. The compounds were tested at three different GPCRs, namely serotoninergic 5-HT1A, adrenergic α1A, and dopaminergic D2 receptors. Our main goal was the discovery of compounds that exhibit, in addition to ChE inhibition, antagonist activity at 5-HT1A because of its involvement in neuronal deficits typical of Alzheimer’s and other neurodegenerative diseases. Ligands with nanomolar affinity for the tested GPCRs were discovered, but most of them behaved as dual antagonists of α1A and 5-HT1A receptors. Nevertheless, several compounds displaying this GPCR affinity profile also showed moderate to good inhibition of AChE and BChE, thus deserving further investigations to exploit the therapeutic potential of such unusual biol. profiles.

Adenylate cyclases (ACs), play a critical role in the conversion of ATP (ATP) into the second messenger cyclic adenosine monophosphate (cAMP). Studies have indicated that adenylyl cyclase type 2 (AC2) is potential drug target for many diseases, however, up to now, there is no AC2-selective agonist reported. In this research, docking-based virtual screening with the combination of cell-based biol. assays have been performed for discovering novel potent and selective AC2 agonists. Virtual screening disclosed a novel hit compound 8 as an AC2 agonist with EC50 value of 8.10μM on recombinant human hAC2 + HEK293 cells. The SAR (structure activity relationship) based on the derivatives of compound 8 was further explored on recombinant AC2 cells and compound 73 was found to be the most active agonist with the EC50 of 90 nM, which is 160-fold more potent than the reported agonist Forskolin and could selectively activate AC2 to inhibit the expression of Interleukin-6. The discovery of a new class of AC2-selective agonists would provide a novel chem. probe to study the physiol. function of AC2.

The structures of these novel mol. tweezers are characterized by 1H NMR, IR, ESI-MS spectra and elemental anal. The recognition properties of these mol. tweezers for D/L-Leu-OMe and D/L-Phe-OMe are investigated by UV-vis spectra.

Purely organic luminophores that exhibit room temperature phosphorescence (RTP) are receiving an ever-growing attention. The design of efficient RTP materials and the understanding of their emissive behavior, however, remain a challenging task. Herein, to gain further insights into metal-free RTP, we report the synthesis, characterization, and photophys. study of chloro-derivatives of [1,2-a:1′,2′-c:1”,2”-e][1,3,5]triazine or cyclic triimidazole (TT). Mono- (1Cl), di- (2Cl) and tri-chloro-TT (3Cl) derivatives are prepared by mild chlorination with N-chlorosuccinimide (NCS). The three compounds are characterized by aggregation-induced emission (AIE) comprising dual fluorescence and multiple phosphorescences, whose origin is disclosed by crystal structure anal. together with accurate DFT/TDDFT calculations Comparison with previously reported bromine and iodine TT derivatives reveals the new chlorinated compounds as the best performing halogenated AIE members of the family.

By combining “”N-chlorosuccinimide (NCS)”” as the safe chlorine source with “”Acr+-Mes”” as the photocatalyst, we successfully achieved benzylic C-H bond chlorination under visible light irradiation Furthermore, benzylic chlorides could be converted to benzylic ethers smoothly in a one-pot manner by adding sodium methoxide. This mild and scalable chlorination method worked effectively for diverse toluene derivatives, especially for electron-deficient substrates. Careful mechanistic studies supported that NCS provided a hydrogen abstractor “”N-centered succinimidyl radical,”” which was responsible for the cleavage of the benzylic C-H bond, relying on the reducing ability of Acr•-Mes.

Xu, Pin; Chen, Peng-Yu; Xu, Hai-Chao published the artcile< Scalable Photoelectrochemical Dehydrogenative Cross-Coupling of Heteroarenes with Aliphatic C-H Bonds>, Safety of 2,6-Dichloro-9-methyl-9H-purine, the main research area is heteroarene photoelectrochem dehydrogenative radical cross coupling light; alkylated heteroarene preparation; C−H functionalization; electrochemistry; heterocycles; photoelectrochemistry; radical reactions.

Heteroarenes are structural motifs found in many bioactive compounds and functional materials. Dehydrogenative cross-coupling of heteroarenes with aliphatic C-H bonds provides straightforward access to functionalized heteroarenes from readily available materials. Established methods employ stoichiometric chem. oxidants under conditions of heating or light irradiation By merging electrochem. and photochem., we have achieved efficient photoelectrochem. dehydrogenative cross-coupling of heteroarenes and C(sp3)-H donors through H2 evolution, without the addition of metal catalysts or chem. oxidants. Mechanistically, the C(sp3)-H donor is converted to a nucleophilic carbon radical through H-atom transfer with chlorine atom, which is produced by light irradiation of anodically generated Cl2 from Cl-. The carbon radical then undergoes radical substitution to the heteroarene to afford alkylated heteroarene products.

A highly efficient aromatic chlorination of arenes such as 1-methyl-indazole, imidazo[1,2-a]pyrazine, phenylthiophene, anthracene, etc. that is catalyzed by DMSO with N-chlorosuccinimide as the chloro source is reported. The mild conditions, easy-availability and stability of the catalyst and reagents, as well as good functional-group tolerance, showed the approach to be a versatile protocol for the late-stage aromatic chlorination of complex natural products, e.g., papaverine, drugs, e.g., diclofenac and peptides, e.g., I. The multi-gram experiment and low-cost of N-chlorosuccinimide and DMSO show great potential for drug discovery and development in industrial applications.
