In a document, author is Zhang, Xiaofei, introduce the new discover.

Selective modulation of metabotropic glutamate receptor 2 (mGlu(2)) represents a novel therapeutic approach for treating brain disorders, including schizophrenia, depression, Parkinson’s disease (PD), Alzheimer’s disease (AD), drug abuse and addiction. Imaging mGlu(2) using positron emission tomography (PET) would allow for in vivo quantification under physiological and pathological conditions and facilitate drug discovery by enabling target engagement studies. In this paper, we aimed to develop a novel specific radioligand derived from negative allosteric modulators (NAMs) for PET imaging of mGlu(2). Methods. A focused small molecule library of mGlu(2) NAMs with tetrahydro naphthyridine scaffold was synthesized for pharmacology and physicochemical evaluation. GIRK dose-response assays and CNS panel binding selectivity assays were performed to study the affinity and selectivity of mGlu(2) NAMs, among which compounds 14a and 14b were selected as PET ligand candidates. Autoradiography in SD rat brain sections was used to confirm the in vitro binding specificity and selectivity of [C-11] 4a and [C-11]14b towards mGlu(2). In vivo binding specificity was then studied by PET imaging. Whole body biodistribution study and radiometabolite analysis were conducted to demonstrate the pharmacokinetic properties of [C-11] 14b as most promising PET mGlu(2) PET ligand. Results. mGlu(2) NAMs 14a-14g were synthesized in 14%-20% yields in five steps. NAMs 14a and 14b were selected to be the most promising ligands due to their high affinity in GIRK dose-response assays. [C-11] 14a and [C-11] 14b displayed similar heterogeneous distribution by autoradiography, consistent with mGlu2 expression in the brain. While PET imaging study showed good brain permeability for both tracers, compound [C-11] 4b demonstrated superior binding specificity compared to [C-11] 14a. Further radiometabolite analysis of [C-11] 4b showed excellent stability in the brain. Conclusions. Compound 14b exhibited high affinity and excellent subtype selectivity, which was then evaluated by in vitro autoradiography and in vivo PET imaging study after labeling with carbon-11. Ligand [C-11] 14b, which we named [C-11]MG2-1904, demonstrated high brain uptake and excellent in vitro/in vivo specific binding towards mGlu(2) with high metabolic stability in the brain. As proof-of-concept, our preliminary work demonstrated a successful example of visualizing mGlu2 in vivo derived from NAMs, which represents a promising chemotype for further development and optimization aimed for clinical translation.

Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. , Application In Synthesis of Adenosine 5′-monophosphate, 61-19-8, Name is Adenosine 5′-monophosphate, molecular formula is C10H14N5O7P, belongs to naphthyridine compound. In a document, author is Dante, Roberto C., introduce the new discover.

A new carbon-nitrogen organic semiconductor has been synthesized by pyrolysis of uric acid. This layered carbon-nitrogen material contains imidazole-, pyridine (naphthyridine)-and graphitic-like nitrogen, as evinced by infrared and X-ray photoelectron spectroscopies. Quantum chemistry calculations support that it would consist of a 2D polymeric material held together by hydrogen bonds. Layers are stacked with an interplanar distance between 3.30 and 3.36 angstrom, as in graphite and coke. Terahertz spectroscopy shows a behavior similar to that of amorphous carbons, such as coke, with non-interacting layers. This material features substantial differences from polymeric carbon nitride, with some characteristics closer to those of nitrogen-doped graphene, in spite of its higher nitrogen content. The direct optical band gap, dependent on the polycondensation temperature, ranges from 2.10 to 2.32 eV. Although in general the degree of crystallinity is low, in the material synthesized at 600 C-circle some spots with a certain degree of crystallinity can be found. (C) 2017 Elsevier Ltd.

A family of highly emissive benzo[4,5]thiazolo[3,2-c][1,3,5,2]oxadiazaborinines, conjugated with the donor 4-dimethylaminophenyl group, was designed and synthesized. Their photophysical, both in solution and in the solid state, and structural properties were investigated. The influence of donor and acceptor substituents (R) in the benzothiazole unit on photo physical properties of complexes was found out. The tetrafluor-obenzothiazole analogue exhibits nonbonded nuclear spin-spin coupling between fluorines from the BF2 group and alpha-fluorine atom at the benzene ring. Additionally, this boron complex demonstrates a comparatively high solid-state fluorescence quantum yield (Phi = 0.34).

Development of a new class of luminescent materials that show high-speed response, high charge carrier mobility, and high brightness is desirable toward realization of next generation of devices, such as electrically pumped organic lasers, visible light communication instruments, and organic light-emitting transistors. In this paper, high-speed organic light-emitting diodes (OLEDs) and high-performance hybrid light-emitting transistors from a new type of solution processable luminescent material, poly[thiophene-2,5-diyl-alt-5,10-bis((2-hexyldecyl)oxy)dithieno[3,2-c:3 ‘,2 ‘-h][1,5]naphthyridine-2,7-diyl] (PTNT), are reported. The OLEDs based on PTNT polymer exhibit a peak brightness of 8 x 10(5) cd m(-2) and 40 MHz modulation frequency under 10 ns pulse operation. This modulation frequency is significantly higher than that of commercially available LEDs, used for visible light communication. Additionally, solution-processed area-emitting hybrid light-emitting transistors with an external quantum yield of 0.25% at brightness of 250 cd m(-2) are demonstrated. Finally, the paper provides device physics and optoelectronic properties of PTNT polymer using ultraviolet photon spectroscopy, inversed photoelectron spectroscopy, and photophysical measurements.

In a document, author is Bacher, Felix, introduce the new discover, Synthetic Route of 298-96-4.

A synthetic route to unsymmetrical 1,8-naphthyridine spacer based ligands is presented. Reaction of a 7-ethyldipyridyl-1,8-naphthyridine-2-carboxaldehyde intermediate with 2-aminophenol or 4,6-di-tert-butyl 2-aminophenol led to the formation of ligands, HL1 and HL2, respectively. Both combined two distinct binding sites: a dipyridyl and an iminophenol site linked through a 1,8-naphthyridine spacer. Treatment of HL1 with copper(II) triflate in the presence of triethylamine/H2O in acetonitrile afforded a tetranuclear complex (1(tox)center dot 2CH(3)CN). X-ray analysis revealed that the structure is constituted by the association of two identical dinuclear units in which the imine is oxidized to an amide group during the complexation. The coordination capabilities of the corresponding free amide ligands H2L1ox and H2L2ox, prepared by an independent route, were explored using copper(II) triflate in the presence of triethylamine/H2O. With the amide ligand, H2L1ox, a similar tetranuclear copper complex (1(tox)center dot 2DMF) compared to the one isolated after complexation with the imine ligand HL1 was formed, as evidenced by X-ray diffraction studies. In contrast, H2L2ox, where the amido phenol arm exhibits two additional tert-butyl groups, has allowed the formation of a trinuclear copper complex (2(triox)center dot H2O).
