In a document, author is Wu, Jing-Fang, introduce the new discover, Product Details of 620-92-8.

Two series of novel 1,5-naphthyridine and 1,6-naphthyridine derivatives were designed and synthesized based on the c-Met kinase inhibitor MK-2461 under the guidance of scaffold hopping strategy. All were tested on c-Met kinase and in vitro anti-tumor activities against Hela and A549 cell lines. The results indicated that 1,6-naphthyridine was a more promising c-Met inhibitory structure core compared with 1,5-naphthyridine. Among them, 26b and 26c showed the best enzymic and cytotoxic activities. The western blot experiments implied that the cytotoxic activity of 26c might be partially through suppressing the phosphorylation of c-Met kinase. (C) 2015 Elsevier Ltd. All rights reserved.

In a article, author is Kobori, Akio, introduce new discover of the category.

Discrimination of base mismatches from normal Watson-Crick base pairs in duplex DNA constitutes a key approach to the detection of single nucleotide polymorphisms ( SNPs). We have developed a sensor for a surface plasmon resonance (SPR) assay system to detect G-G, A-A, and C-C mismatch duplexes by employing a surface upon which mismatch-binding ligands (MBLs) are immobilized. We synthesized a new MBL consisting of 2,7-diamino-1,8-naphthyridine (damND) and immobilized it onto a CM5 sensor chip to carry out the SPR assay of DNA duplexes containing a single-base mismatch. The SPR sensor with damND revealed strong responses to all C-C mismatches, and sequence-dependent C-T and T-T mismatches. Compared to ND- and naphthyridine-azaquinolone hybrid (NA)-immobilized sensor surfaces, with affinity to mismatches composed of purine nucleotide bases, the damND-immobilized surface was useful for the detection of the mismatches composed of pyrimidine nucleotide bases.

A wide range of biological properties establishes them as potent scaffolds in therapeutic and medicinal research. The broad spectrum of activities primarily includes antimicrobial, antiviral, anticancer, anti-inflammatory, and analgesic activities. 1,8-Naphthyridine derivatives have also exhibited potential applications in neurological disorders such as Alzheimer’s disease, multiple sclerosis, and depression. In addition, these synthetic derivatives have been found to possess activities such as anti-osteoporotic (alpha(v)beta(3) antagonists), anti-allergic, antimalarial, gastric antisecretory, bronchodilator, anticonvulsant, antihypertensive, platelet aggregation inhibition, anti-oxidant, EGFR inhibition, protein kinase inhibition, ionotropic agent, beta-3 antagonist, MDR modulator, adenosine receptor agonist, adrenoceptor antagonist, and pesticide activities.

In an article, author is Chen, Cheng, once mentioned the application of 573-17-1, Name is 9-Bromophenanthrene. Now introduce a scientific discovery about this category, Formula: https://www.ambeed.com/products/573-17-1.html.

Three new 1,8-naphthyridine-based thermally activated delayed fluorescence (TADF) emitters, 2,7-di(9,9-dimethylacridin-10(9H)-yl)-1,8-naphthyridine (DMAC-ND), 2,7-di(10H-phenothiazin-10-yl)-1,8-naphthyridine (PTZ-ND) and 2,7-di(10H-phenoxazin-10-yl)-1,8-naphthyridine (PXZ-ND), were designed and synthesized. They possessed twisted structures and small Delta E-ST, which could make them show excellent TADF and AIDF properties. Consequently, multi-color organic light-emitting diodes (OLED) based on emitters DMAC-ND, PTZ-ND and PXZ-ND were fabricated, which could achieve a maximum external quantum efficiency (EQE) of 14.1, 13.4 and 13.0%, respectively. Moreover, all devices exhibited relatively low turn-on voltages and low efficiency roll-off ranging from 4.5% to 20% at the luminance of 1000 cd m(-2) probably owing to the microsecond-scale delayed photoluminescence (PL) and AIDF properties of the emitters. Notably, a DMAC-ND-based non-doped device reached the luminance of 20000 cd m(-2) easily at the voltage of 6.5 V, and exhibited very low efficiency roll-off of 4.5% at the luminance of 1000 cd m(-2) and 33.6% at the luminance of 10000 cd m(-2).

The L-shaped, pi-extended pentacycle dibenzopyrrolo[1,2-a][1,8]naphthyridine and its derivatives were synthesized using two methods: fully intramolecular [2 + 2 + 2] cycloaddition and oxidative aromatization using substituted carbodiimide and modification of an electron-rich indole ring of an L-shaped skeleton via electrophilic reaction and cross-coupling. These L-shaped compounds emitted fluorescence in high quantum yield. The position of substituents affected the fluorescence color through two different mechanisms, x-conjugation and skeletal distortion, which caused the substituted L-shaped compounds to emit fluorescence in a variety of colors and to exhibit solvato-fluorochromism.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind.
