Newly synthesised 1,8-naphthyridine-based molecular probes, NAP-1 and NAP-2, exhibit highly selective fluorescence responses towards the toxic cadmium over coordinatively competing Zn2+ and several other metal ions examined. On the one hand, NAP-1 (MeOH:H2O, v/v 80:20, pH 7.4) exhibits ca. 1.5 order of magnitude higher stability constant for Cd2+ over Zn2+; on the other hand, NAP-2 in MeOH offers unique selectivity only towards Cd2+, exhibiting both absorbance and emission red shifts as well as fluorescence enhancement. By 1H NMR analysis, the tetra-coordinated binding is indicated at least for the NAP-1+Cd2+ complex and theoretical calculations reveal relatively stronger binding of Cd2+ over Zn2+. [image omitted].

A new asymmetrical photochromic diarylethene has been synthesized by using 1,8-naphthyridine as a functional group and perfluorodiarylethene as photoswitching unit via a peptide bond linkage, and its molecular structure was characterized by single crystal X-ray diffraction analysis. The compound exhibited favorable photochromism upon irradiation with UV/vis light, and its fluorescent behaviour could be efficiently modulated by light, base/acid, and metal ion in THF. The deprotonated derivative of the diarylethene also showed good photochromism, and displayed remarkable turn-on fluorescence response during photocyclization process. Furthermore, the diarylethene was highly selective toward Cd2+ with an obvious fluorescent color change from dark to bright green in THF. Finally, a logic circuit was fabricated with four inputs of the combinational stimuli of UV/vis and Cd2+/EDTA, and one output of fluorescence intensity. (C) 2016 Elsevier Ltd. All rights reserved.

Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. In an article, author is Matsumoto, Saki, once mentioned the application of 573-17-1, Name is 9-Bromophenanthrene, molecular formula is C14H9Br. Now introduce a scientific discovery about this category, Quality Control of 9-Bromophenanthrene.

Programmed -1 ribosomal frameshifting (-1PRF) is a recoding mechanism to make alternative proteins from a single mRNA transcript. -1PRF is stimulated by cis-acting signals in mRNA, a seven-nucleotide slippery sequence and a downstream secondary structure element, which is often a pseudoknot. In this study we engineered the frameshifting pseudoknot from the mouse mammary tumor virus to respond to a rationally designed small molecule naphthyridine carbamate tetramer (NCTn). We demonstrate that NCTn can stabilize the pseudoknot structure in mRNA and activate -1PRF both in vitro and in human cells. The results illustrate how NCTn-inducible -1PRF may serve as an important component of the synthetic biology toolbox for the precise control of gene expression using small synthetic molecules.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states. I hope my blog about 573-17-1 is helpful to your research. Quality Control of 9-Bromophenanthrene.

In a document, author is Husain, Asif, Synthetic Route of 620-92-8.

Background: The prevalence of morbidity and mortality due to infections from parasitic worms and protozoa is on rise especially in third world countries. The situation is further worsened by drug resistant microbial pathogens. Objectives: The antimicrobial and anthelmintic activities associated with substituted furfuraldehyde and 1,8-naphthyridine nucleus of nalidixic acid prompted us to synthesize some new quinolone Schiff bases with an aim to obtain potent antibacterial and anthelmintic agents with improved safety and efficacy. Methods: A new series of 1,8 naphthyridine based Schiff bases were designed and synthesized by the reaction of Nalidixic acid methyl ester 1 with hydrazine hydrate in anhydrous condition which yielded 1-ethyl-1,4-dihydro-7-methyl-4-oxo-1,8-naphthyridine-3-carbohydrazide 2. The compound 2 was further treated with several furfural aldehydes to furnish the desired Schiff bases (3a-k). The in vitro antibacterial activity of Schiff bases was investigated against four Gram positive and four Gram negative bacterial strains. The newly prepared Schiff bases were also tested for their anthelmintic activity against Pheritima posthuma and Perionyx excavatus. Results: Chemical structures and identity of the prepared compounds were confirmed by their spectral data. Overall, Schiff bases (3a-k) showed good antimicrobial activity and interestingly five compounds exhibited more potent inhibitory effect than the standard drug Ampicillin against S. aureus, B. cereus, E. faecalis, S. epidermidis, E. coli, S. typhi and S. dysenteriae. Schiff bases also exhibited significant anthelmintic activity as indicated by their mean paralyses time (min) of 7.07-16.49, and 11.23-20.46 min against Perionyx excavatus and Pheritima posthuma in comparison to the 8.23 and 12.58 min shown by standard drug-Albendazole. Conclusion: It could be proposed that substitution of aromatic ring at C-5 of furfuryl heterocyclic ring in the Schiff bases produce compounds with promising antibacterial and anthelmintic actions.
