Chen, Tianpeng;Wei, Yingying;Zhu, Gaoyang;Zhao, Huajun;Zhang, Xingxian research published 《 Design, synthesis and structure-activity relationship studies of 4-indole-2-arylaminopyrimidine derivatives as anti-inflammatory agents for acute lung injury》, the research content is summarized as follows. Acute lung injury/acute respiratory distress syndrome (ALI/ARDS), a clin. high mortality disease, has not been effectively treated till now, and the development of anti-acute lung injury drugs is imminent. Acute lung injury was efficiently treated by inhibiting the cascade of inflammation, and reducing the inflammatory response in the lung. A series of novel compounds with highly efficient inhibiting the expression of inflammatory factors were designed by using 4-indolyl-2-aminopyrimidine as the core skeleton. Totally eleven 4-indolyl-2-arylaminopyrimidine derivatives were designed and synthesized. As well, the related anti-ALI activity of these compounds was evaluated. Compounds I and II showed a superior activity among these compounds, and the inhibition rate of IL-6 and IL-8 release ranged from 62% to 77%, and from 65% to 72%, resp. Furthermore, most of compounds had no significant cytotoxicity in vitro. The infiltration of inflammatory cells into lung tissue significantly reduced by using compound II (20 mg/kg) in the ALI mice model, which achieved the effect of protecting lung tissue and improving ALI. In addition, the inflammatory response was inhibited by using compound II through inhibiting phosphorylation of p-38 and ERK in MAPK signaling pathway, and resulted in protective effect on ALI. These data indicated that compound II showed good anti-inflammatory activity in vitro and in vivo, which was expected to become a leading compound for the treatment of ALI.

Chen, Tsun-Ren;Chen, Yu-Tung;Chen, Yi-Sheng;Lee, Wen-Jen;Lin, Yen-Hsing;Wang, Hao-Chen research published 《 Iridium/graphene nanostructured catalyst for the N-alkylation of amines to synthesize nitrogen-containing derivatives and heterocyclic compounds in a green process》, the research content is summarized as follows. A facile iridium/graphene-catalyzed methodol. providing an efficient synthetic route for C-N bond formation is reported. This catalyst can directly promote the formation of C-N bonds, without pre-activation steps, and without solvents, alkalis and other additives. This protocol provides a direct N-alkylation of amines using a variety of primary and secondary alcs. with good selectivity and excellent yields. Charmingly, the use of diols resulted in intermol. cyclization of amines, and such products are privileged structures in biol. active compounds Two examples illustrate the advantages of this catalyst in organic synthesis: the tandem catalysis to synthesize hydroxyzine, and the intermol. cyclization to synthesize cyclizine. Water is the only byproduct, which makes this catalytic process sustainable and environmentally friendly.

Budovska, Mariana;Krochtova, Kristina;Kuba, Miroslav;Tischlerova, Viera;Mojzis, Jan research published 《 Synthesis and cytotoxicity evaluation of novel 5-fluorinated indoles》, the research content is summarized as follows. Authors report herein the synthesis of a small 28-membered library of novel 5-fluorinated indole phytoalexins. Target compounds were designed by a structure-based bioisosterism strategy. The newly prepared compounds were screened in vitro for cytotoxic activity against seven human cancer cell lines. The cytotoxic evaluation revealed that the 2′-(3,4-dichlorophenylamino) analog of 5-fluorospirobrassinin was the most active against cancer cell lines without causing toxicity to HUVEC cells. Overall, 5-fluoro analogs of indole phytoalexins did not show improved anti-cancer activity compared to the lead compounds The preliminary structure-activity relationship (SAR) study revealed that placing fluoro substituent at C-5 position of the indole ring is not crucial for inducing cytotoxicity against a cancer cell line.

Direct alkylation of the C-H bond arenes in a selective manner is a long-standing challenge. Herein, a metal-free photocatalytic regioselective C-H alkylation method for electron-rich arenes with both activated and unactivated alkenes was developed. The reaction tolerates a wide range of aromatic rings with diverse substitution patterns, as well as terminal and internal alkenes, providing a general and straightforward metal-free method for C-C bond formation from inert C-H bonds. Moreover, alkynes are also compatible to give the C-H vinylation of electron-rich arenes.

Chen, Guobin;Yuan, Hengyi research published 《 Effects of carbon nanomaterials on the migration and fate of organic pollutants in the ecological environment》, the research content is summarized as follows. The purpose of this study was to investigate the mechanism of adsorption reaction between heterocyclic organic compounds with different number of ring atoms and different atoms replacing carbon atoms and carbon nanotubes with different surface functional groups. Based on the current situation of research on adsorption of carbon nanomaterials adsorbing organic pollutants, the existing problems and limitations were analyzed by studying the properties and characterization of single-walled carbon nanotubes, oxidized single-walled carbon nanotubes and non-porous graphite powder, such as elemental anal., transmission electron micrograph, zero charge point, etc. The three adsorption materials were investigated by batch experiment Six compounds of thiophene, pyrimidine, benzene, aniline, 2-aminopyrimidine and 4,6-diaminopyrimidine were selected as the adsorbate for detecting adsorption capacity. The results showed that the affinity of different adsorbents on different adsorbents varied greatly. The adsorption capacity of heterocyclic compounds containing N and S was greatly enhanced by non-hydrophobic action. And the degree of oxidation of the adsorbent and the pH of the solution determined the adsorption capacity of the adsorbent for nitrogen-containing heterocyclic compounds Therefore, in the ecol. environment, the migration of hydrophilic organic pollutants in the environment can be reduced by the preparation of appropriate carbon nanotubes.

Blum, Stephan P.;Karakaya, Tarik;Schollmeyer, Dieter;Klapars, Artis;Waldvogel, Siegfried R. research published 《 Metal-Free Electrochemical Synthesis of Sulfonamides Directly from (Hetero)arenes, SO₂, and Amines》, the research content is summarized as follows. Sulfonamides are among the most important chem. motifs in pharmaceuticals and agrochems. However, there is no methodol. to directly introduce the sulfonamide group to a non-prefunctionalized aromatic compound Herein, we present the first dehydrogenative electrochem. sulfonamide synthesis protocol by exploiting the inherent reactivity of (hetero)arenes in a highly convergent reaction with SO₂ and amines via amidosulfinate intermediate. The amidosulfinate serves a dual role as reactant and supporting electrolyte. Direct anodic oxidation of the aromatic compound triggers the reaction, followed by nucleophilic attack of the amidosulfinate. Boron-doped diamond (BDD) electrodes and a HFIP-MeCN solvent mixture enable selective formation of the sulfonamides. In total, 36 examples are demonstrated with yields up to 85%.

Bagheri, Sotoodeh research published 《 Theoretical study of hydrogen bonds and electronic properties in hexagonal arrangements composed of self-assembled DNA analogues》, the research content is summarized as follows. Abstract: Aminopyrimidine, triaminopyrimidine, and cyanuric acid as artificial bases can be used to design and prepare multi-stranded DNA structures. In this manuscript, we theor. investigate the stability of hydrogen-bonded hexagonal structures arising from the self-assembly of aminopyrimidine and cyanuric acid, as well as triaminopyrimidine and cyanuric acid in gas phase and in water. The influence of hydrogen bonds on the stability of hexagonal arrangements is examined by atoms in mols. and natural bond orbital analyses. Moreover, the mutual effects of hydrogen bonds on each other are also evaluated in the hexagonal structures using cooperative energy. Whereas the self-assembly of the hydrogen-bonded hexagonal arrangements may be considered to form new nanostructures, metal sensors, and ion channels, some electronic properties such as band gap, first ionization energy, electron affinity, electronegativity, electronic chem. potential, electrophilicity index, global chem. hardness, and chem. softness are theor. estimated at M06-2X/6-311++G(d,p) level.
