Nanomaterials Based Electrochemical Sensors for Serotonin Detection: A Review

The present review deals with the recent progress made in the field of the electrochemical detection of serotonin by means of electrochemical sensors based on various nanomaterials incorporated in the sensitive element. Due to the unique chemical and physical properties of these nanomaterials, it was possible to develop sensitive electrochemical sensors with excellent analytical performances, useful in the practice. The main electrochemical sensors used in serotonin detection are based on carbon electrodes modified with carbon nanotubes and various materials, such as benzofuran, polyalizarin red-S, poly(L-arginine), Nafion/Ni(OH)(2), or graphene oxide, incorporating silver-silver selenite nanoparticles, as well as screen-printed electrodes modified with zinc oxide or aluminium oxide. Also, the review describes the nanocomposite sensors based on conductive polymers, tin oxide-tin sulphide, silver/polypyrole/copper oxide or a hybrid structure of cerium oxide-gold oxide nanofibers together with ruthenium oxide nanowires. The presentation focused on describing the sensitive materials, characterizing the sensors, the detection techniques, electroanalytical properties, validation and use of sensors in lab practice.

Bis(benzofuran-enaminone) hybrid possessing piperazine linker: Versatile precursor for microwave assisted synthesis of bis(pyrido[2 ‘,3 ‘:3,4]pyrazolo[1,5-a]pyrimidines)

We reported herein efficient procedures for the synthesis of new piperazine-linked bis(pyrido[2′,3’:3,4]pyrazolo[1,5-a]pyrimidines) using bis(benzofuran-enaminone) hybrid as a key intermediate. For this purpose, bis(enaminone) were reacted with a new series of 3-amino-4-(thiophen-2-yl)-1H-pyrazolo[3,4-b]pyridines in pyridine under microwave irradiation at 120 degrees C for 90 min to afford the target bis(pyrimidines). 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 equivalents of the appropriate enaminones as well as arylidinemalononitriles in pyridine under microwave irradiation at 120 degrees C for 2 h to afford the target bis(pyrimidines). Furthermore, a mixture of bis(pyrazolopyridine) reacted with two equivalents of 1,3-diketones and beta-ketoesters in glacial acetic acid was microwave irradiated at 130 degrees C for 90 min to give bis(2,4-disubstituted pyrimidines) and bis(2-substituted pyrimidin-4(1H)-ones), respectively. The structures of the new hybrids were confirmed via considering their elemental analyses as well as their spectral data. [GRAPHICS] .

Gold(I)-Catalyzed Cascade Cyclization Reactions of Allenynes for the Synthesis of Fused Cyclopropanes and Acenaphthenes

A gold-catalyzed reaction of phenylene-tethered allenynes with benzofurans gave 1-(naphth-1-yl)cyclopropa[b]benzofuran derivatives, whereas the reaction of 1-allenyl-2-ethynyl-3-methylbenzene derivatives in the absence of benzofurans gave acenaphthenes in good yields. These results can be rationalized by nucleophilic attack of the alkyne moiety on an activated allene to form a vinyl cation intermediate.

Refined RGB Strategy for the Synthesis of Polymer-Based Full Organic Luminescent Nanotubes with Broad Emission Bands

Light-emitting polymer nanotubes with tailored fluorescence emission bands have been prepared using organic emissive materials based on benzofuran, carbazole, and indolocarbazole scaffolds and investigated with the goal to obtain pure white-light emission at the nanoscale. The polymer nanostructures were obtained by the anodic aluminium oxide (AAO) template method with PMMA as a transparent polymer matrix and a proficient choice of organic dyes emitting in the blue, green, yellow and red parts of the spectral range. It is demonstrated that combining aqueous dispersions of monochromatic nanotubes is an effective way of generating white light emission due to a simple correlation between the individual color components. Furthermore, it is also possible to target white emission at the nanoscale by adjusting the concentration of the dyes inside single nanotubes in order to obtain optimal color coordinates ofca. 0.3 in the CIE chromaticity diagram.

Spirobiflavonoid stereoisomers from the endangered conifer Glyptostrobus pensilis and their protein tyrosine phosphatase 1B inhibitory activity

Six spirobiflavonoid stereoisomers including two new ones, spiropensilisols A (1) and B (2), were isolated from a mass-limited trunk barks of Glyptostrobus pensilis, an endangered conifer endemic to China. The new structures featuring a benzofuran-containing spirolactone and their absolute configurations were determined by extensive spectroscopic methods. All the isolates showed significant inhibitory activities against the human protein tyrosine phosphatase 1B (PTP1B) enzyme, a potential therapeutic target for diabetes and obesity, with IC50 values ranging from 3.3 to 17.1 mu M. A preliminary SAR analysis with assistance of the molecular modeling approach was performed for the most potent compound (i.e., 1), to understand the nature of interactions governing the binding mode of spirobiflavonids within the active site of the PTP1B enzyme.
