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.

Catalytic C(sp(2))-H Amination Reactions Using Dinickel Imides

C-H amination reactions are valuable transformations for the construction of C-N bonds. Due to their relatively high bond dissociation energies, C(sp(2))-H bonds are generally not susceptible toward direct nitrene insertion, necessitating alternative mechanisms for C-H activation. Here, we report that cationic dinuclear (NDI)Ni-2 (NDI = naphthyridine-diimine complexes catalyze intramolecular nitrene insertions into aryl and vinyl C(sp(2))-H bonds. Mechanistic studies suggest that a bridging imido ligand supported at a Ni-2 site induces C-H activation by a 1,2-addition pathway to generate an azametallacyclic intermediate. This organometallic mechanism contrasts with the electrocyclization/1,2-shift mechanism proposed for analogous transformations using Rh-2 catalysts. The implications of these mechanistic differences for the stereoselectivity and chemoselectivity of C-H amination are described.

Oxidative route to polyoxomolybdates from quadruply bonded [Mo-II equivalent to Mo-II] precursor: Structural characterization of a tetranuclear cluster [Mo4Cl5O8(pyNP)(2)] (pyNP = (2-(2-pyridyl)1,8-naphthyridine))

Aerial oxidation of the quadruply bonded Mo-2(OAc)(4) in the presence of HprNP (2-(2-pyrrolyl)-1,8-naphthyridine) in CH2Cl2 provide the dinuclear oxochloromolybdate [Mo2O2Cl2(mu(2)-O)(2)(HprNP)(2)] (1). The molecular structure of 1 consists of the [Mo2O2Cl2(mu(2)-O)(2)] core with the cisoid Mo=O bonds and each HprNP ligand chelating the Mo center through the naphthyridine unit. An alternate route to access oxomolybdates is to employ quadruply bonded [Re2Cl8](2-) to oxidize cis-[Mo-2(pyNP)(2)(OAC)(2)][BF4](2) (pyNP = 2-(2-pyridyl)1,8-naphthyridine). The isolated compound is the tetranuclear molybdenum cluster [Mo4Cl5O8(pyNP)(2)] (2). The molecular formula of compound 2 is best described as [Mo2Cl3O2(mu(2)-O)(eta(3)-pyNP)][mu(3)-O][Mo2Cl2O2(mu(2)-O)(2)(eta(2) -pyNP)], the fusion of two oxochlorodimolybdates linked through a mu(3)-oxo linkage. The oxidation of the [Mo-coproduct equivalent to Mo-coproduct] unit to highly oxidized oxomolybdates and subsequent dimerization to tetranuclear core offers prospect for accessing new types of oxo-chloro-molybdenum clusters exhibiting interesting structural motifs.

Two-photon absorption properties of BODIPY-like compounds based on BF2-naphthyridine complexes

Boron dipyrromethene type molecules (BODIPYs) are versatile molecules which have been used for applications ranging from photodynamic therapy to solar cells (DSSC). However, these molecules usually do not present high two-photon absorption cross-sections, limiting their use in nonlinear optical applications. Herein, we study a series of BF2-naphthyridine based boron-complexes with electron-donating and withdrawing groups to increase their two-photon absorption. We have found two-photon absorption cross-sections up to approximately 270 GM, which corresponds to an increase of approximately five times in comparison to the average cross-section value reported for molecules with similar conjugation length, indicating such compounds as potential materials for nonlinear applications in both the visible and infrared spectral regions.
