New macrocyclic compounds with naphthyridine units for molecular recognition studies of biotin and urea derivatives

Two macrocyclic hosts containing benzenedicarboxamide or pyridinedicarboxamide moieties and two 1,8-naphthyridine units linked by a crown ether like chain, have been synthesized and fully characterized by multinuclear NMR spectroscopy. X-ray diffraction analysis is provided for one of the macrocycles including a DMSO guest molecule. Binding constant determination of both hosts with four ureido derivatives, amongst them (+)-biotin methyl ester, was achieved by means of H-1 NMR titrations.

The Friedlander reaction: A powerful strategy for the synthesis of heterocycles

Ever since it was discovered and used widely in the synthesis of different organic compounds, quinoline became an interesting framework among chemists and pharmacists due to its unique properties. There are many familiar named reactions developed for the synthesis of quinoline based structures, among which the Friedlander reaction plays an important role. This method involves the condensation between 2-aminobenzaldehydes and a ketone. By developing the Friedlander synthesis, different types of heterocycles have been prepared in addition to the quinolines. In this chapter, the focus is on the applicability of the Friedlander reaction to the synthesis of various types of heterocyclic compounds.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 754-05-2. The above is the message from the blog manager. Recommanded Product: Trimethyl(vinyl)silane.

Luminescence-based colorimetric discrimination of single-nucleotide transversions by the combined use of the derivatives of DOTA-conjugated naphthyridine and its terbium complex

We newly synthesized a nucleobase-binding ligand, ND-DOTA, in which 2-amino-5,7-dimethyl-1,8-naphthyridine (ND) was conjugated with 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid (DOTA) via an amide linker, and found that its terbium(III) complex (ND-DOTA-Tb) showed green emission based on an energy transfer from the naphthyridine moiety to Tb3+. The blue emission of ND-DOTA was selectively quenched by adding abasic site-containing DNA duplexes that have pyrimidine bases opposite to the abasic site. In contrast, at the same excitation wavelength, ND-DOTA-Tb showed green emission independently of the bases opposite to the abasic site. Thus, a mixed solution of ND-DOTA and ND-DOTA-Tb enabled the luminescence-based colorimetric discrimination of single-nucleotide transversions with the naked eye at a single excitation wavelength.

Electronic and structural properties of N -> B-ladder boranes with high electron affinity

A series of new pi-conjugated N -> B-ladder boranes has been prepared in high yield by two-fold hydroboration of bifunctional quaterpyridine-, pyrimidine-, and 1,5-naphthyridine-based precursors with 9H-BBN and Piers’ borane ((C6F5)(2)BH). The structures of several ladder-boranes have been confirmed by X-ray crystallography, and their optical and electrochemical properties have been characterized, and complemented by DFT calculations. The electronic structure of the individual ladder boranes, as well as differences in the optical properties that originate from the chemical structure of the boryl-side-chains, are discussed. The results consistently show that, compared to the precursors, the optical gaps of the ladder boranes are significantly reduced, and the electron affinities are strongly increased to between -3.4 and -4.0 eV. Further investigations of chemically and electrochemically reduced species indicate that excess electrons in these kinds of systems are effectively delocalized throughout the conjugated systems.

A new fluorescent enhancement chemosensor for Al3+ and Fe3+ based on naphthyridine and benzothiazole groups

A novel and easily synthesized compound, N-(2-(2-benzothiazol-2-yl)vinyl-4-methyl-1,8-naphthyrine-7-yl)acetamide (1) based on naphthyridine and benzothiazole group, has been developed as a turn-on fluorescent chemosensor for Al3+ and Fe3+ simultaneously. The absorbance and fluorescent intensities of 1 increased linearly in aqueous solution upon the interaction of 1 with Al3+ or Fe3+. The other co-existing metal ions have no obvious effect on the detection. The Job’s plot and the ESI mass spectra indicated the formation of 1:1 complex between 1 and Al3+ or Fe3+. The sensing mechanism was proposed according to the Job’s plot, ESI mass spectra, H-1 NMR spectra, and density functional theory (DFT) calculation. The properties of the model compound N-(2-((2-methylbenzothiazol-6-ylimino)methyl)-4-methyl-1,8-naphthyridin-7-yflacetamide (2), which was designed and synthesized in order to prove the sensing mechanism, also verified the proposed sensing mechanism.

Theoretical Study of the Peripheral Disulfide Bridge Substituent Effects on the Antioxidant Properties of Naphthyridine Diol Derivatives

The effect of a peripheral disulfide bridge substituent on the phenolic O-H bond dissociation energy (BDE) and the ionization potential (IP) of naphthyridine diol has been studied by density functional theory (DFT) calculation. Compared with naphthalene diol, the substituent of a peripheral disulfide bridge group is very efficient in reducing the BDE, whereas the insertion of nitrogen atoms into the naphthalenic ring only slightly changes the BDE of O-H bond but dramatically enhances the IP. It is similar with the stereoelectronic effect of the heterocyclic ring for the well-known alpha-tocopherol antioxidant and leads to a highly delocalized spin distribution. With the incorporation of these two aspects, a potential antioxidant is expected to be more active and more stable than alpha-tocopherol.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1066-54-2, in my other articles.
