Naphthyridine-based receptors for flurometric detection of urea and biotin

Naphthyridine-based receptors 1-4 have been designed and synthesized for the recognition of urea in CHCl3 containing 1% CH3CN. Receptor 1 also binds biotin and its methyl ester with moderate binding constant values. In comparison, receptor 2 is less efficient in recognising biotin and its methyl ester analogue. Receptor 1 binds urea and biotin with binding constant values of 1.02 x 10(4) and 1.08 x 10(4) M-1, respectively, in CHCl3 containing 1% CH3CN and shows significant change in emission of naphthyridine upon complexation. Characterization and sensing properties of the receptors were evaluated by H-1 NMR, UV-vis and fluorescence spectroscopic methods.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 179324-87-9. COA of Formula: C17H29BF3NO4.

Enhancement of affinity in molecular recognition via hydrogen bonds by POSS-core dendrimer and its application for selective complex formation between guanosine triphosphate and 1,8-naphthyridine derivatives

We report that a polyhedral oligomeric silsesquioxane (POSS) core in a dendrimer can enhance the affinity of the molecular recognition via hydrogen bonds between 1,8-naphthyridine and guanosine nucleotides. The complexation of the naphthyridine ligands with a series of guanosine nucleotides was investigated, and it is shown that the POSS core should play a significant role in the stabilization of the complexes via hydrogen bonds. Finally, we demonstrate that the 1,8-naphthyridine ligand can selectively recognize guanosine triphosphate by assisting with the POSS-core dendrimer.

Application of 89343-06-6, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 89343-06-6 is helpful to your research.

Double-stranded helicates of Ni(II), Co(II), Fe(II) and Zn(II) with oligo-alpha-naphthyridylamino ligand: Synthesis, structure and properties

By using tetranaphthyridyl-triamine ligand, N-2-(2-(1,8-naphthyridin-7-ylamino)-1,8-naphthyridin-7-yl)-N-7-(1,8-naphthyridin-2-yl)-1,8-naphthyridine-2,7-diamine (H(3)tentra), double-stranded dinuclear helical compounds [M-2(H(3)tentra)(2)(ClO4)(4)] [M = Ni-II (1), Co-II (2), Fe-II (3), Zn-II (4)] were synthesized and structurally characterized. The single X-ray crystal structure of iron(II) complex showed that both of H(3)tentra ligands wrap around the metal-metal axis giving rise to a double-stranded dinuclear helical compound with Fe-Fe separation of ca. 5.326 angstrom. Each ligand uses two nitrogen atoms from two different napthyridine rings, to coordinate one metal centre (Fe or Fe(A)) and therefore, the geometry about the metal ions was described as distorted tetrahedral, with both ligands acting as bisbidentate N4 donors. This distortion is shown by the angles between nitrogen and iron atoms, which range from 80.45(15) to 143.32(14)degrees. Distorted tetrahedral environment was also proposed for the other complexes on the basis of the magnetic measurements and X-ray results. Strong pi-pi interactions were observed for all synthesized double stranded helicates of H(3)tentra ligand. The measured chi T-M values at 300 K for complexes 2 and 3 found larger than the expected values for two high-spin Co(II) with S = 3/2 and for Fe(II) ions with S = 2 and g = 2, which attributed to the unquenched orbital coupling.

Co(OAc)(2)-Catalyzed Trifluoromethylation and C(3)-Selective Arylation of 2-(Propargylamino)pyridines via a 6-Endo-Dig Cyclization

A Co(OAc)(2)-catalyzed trifluoromethylation and subsequent C(3) -selective arylation of 2-(propargylamino)-pyridines has been developed. A new 6-endo-dig cyclization involving an unprecedented C(3) selective arylation of the pyridines instead of a commonly observed 5-exo-dig cyclization with N is realized. Moreover, the study presents the first case of the installation of a trifluoromethyl group into electron deficient azaarenes. The process delivers an efficient cascade approach to new trifluoromethylated 1,8-naphthyridine structures with a broad substrate scope.

Self-Assembled Cagelike Receptor That Binds Biologically Relevant Dicarboxylic Acids via Proton-Coupled Anion Recognition

We report here a fully organic, self-assembled dimeric receptor, constructed from acyclic naphthyridyl-polypyrrolic building blocks. The cagelike dimer is stable in the solid state, in solution, and in gas phase, as inferred from X-ray diffraction and spectroscopic analyses. This system acts as a receptor for oxalic acid, maleic acid, and malonic acid in the solid state and in THF solution. In contrast, acetic acid, propionic acid, adipic acid, and succinic acid, with pK(a) values > ca. 2.8, were not bound effectively within the cagelike cavity. It is speculated that oxalic acid, maleic acid, and malonic acid serve to protonate the naphthyridine moieties of the host, which then favors binding of the corresponding carboxylate anions via hydrogen-bonding to the pyrrolic NH protons. The present naphthyridine- polypyrrole dimer is stable under acidic conditions, including in the presence of 100 equiv trifluoroacetic acid (TFA), p-toluenesulfonic acid (PTSA), H2SO4, and HCI. However, disassembly may be achieved by exposure to tetrabutylammonium fluoride (TBAF). Washing with water then regenerates the cage. This process of assembly and disassembly could be repeated >20 times with little evidence of degradation. The reversible nature of the present system, coupled with its dicarboxylic acid recognition features, leads us to suggest it could have a role to play in effecting the controlled capture and release of biologically relevant dicarboxylic acids.

Study of the Hetero-[4+2]-Cycloaddition Reaction of Aldimines and Alkynes. Synthesis of 1,5-Naphthyridine and Isoindolone Derivatives

Both experimental and computational studies for the cycloaddition reaction between N-(3-pyridyl)aldimines and acetylenes where 1,5-naphthyridines are obtained are reported. The reaction of benzaldimine with a methoxycarbonyl group in position 2 with phenyl acetylene, styrene, and indene afforded polycyclic isoindolone derivatives. The mechanism of reaction of N-(3pyridyl)aldimines with olefins can be explained by an asynchronous [4+2] cycloaddition; in the case of acetylenes, the obtained results suggest a stepwise mechanism through a 3-azatriene.

Electrochemical, Theoretical, and Surface Morphological Studies of Corrosion Inhibition Effect of Green Naphthyridine Derivatives on Mild Steel in Hydrochloric Acid

The corrosion inhibition efficiencies of three novel naphthyridines namely, 5-amino-9-hydroxy-2-phenylchromeno[4,3,2-de][1,6]-naphthyridine-4-carbonitrile (N-1), 5-amino-9-hydroxy-2-(p-tolyl)chromeno-[4,3,2-de][1,6]naphthyridine-4-carbonitrile (N-2), and 5-amino-9-hydroxy-2-(4-methoxyphenyl) chromeno [4,3,2-de] [1,6] naphthyridine-4-carbonitrile (N-3) have been investigated for mild steel in 1 M HCl solution by using weight loss, electrochemical impedance spectroscopy, and potentiodynamic polarization methods. All three compounds show high inhibition activities at 6.54 X 10(-5) M: N-1, 94.28%; N-2, 96.66%; and N-3, 98.09%. Electrochemical impedance spectroscopy analysis reveals an increase in polarization resistance due to the adsorbed inhibitor molecules on metal surface. Potentiodynamic polarization analysis reveals that all three compounds act as mixed-type inhibitors but of predominantly cathodic type. The adsorption of the studied compounds on mild steel surface follows the Langmuir adsorption isotherm. Surface morphology examined by using scanning electron microscopy and atomic force microscopy analysis shows a smoother surface for mild steel in the presence of naphthyridines in acidic solution. Quantum chemical parameters correlate well with the experimental results, which support higher inhibition efficiencies of N-3 and N-2 due to the electron-donating effects of -OCH3 and -CH3 substituents, respectively, than of N-1, which is devoid of substituents. The magnitudes of the adsorption energies obtained from Monte Carlo simulations also agree with the trend of the experimental inhibition efficiency.

Application of 61-19-8, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 61-19-8 is helpful to your research.

Photoswitchable molecular glue for DNA

DNA molecular glue is a small synthetic ligand that can adhere two single-stranded DNAs that do not spontaneously hybridize with each other. For reversible control of DNA hybridization by an external light stimulus, we have developed a photoswitchable molecular glue for DNA. The photoswitchable molecular glue, NCDA, consists of two guanine-recognizing naphthyridine moieties connected with a photochromic azobenzene unit. Azobenzene undergoes a reversible cis/trans isomerization by photoirradiation, which changes the relative orientations and positions of the naphthyridine moieties, resulting into photoswitching of NCDA binding to the DNA containing GG-mismatch. NCDA in the cis configuration binds to a GG-mismatch sequence and induces the formation of the DNA duplex. Using the photoswitchable binding property of NCDA, the hybridization event of two natural unmodified DNAs can be reversibly controlled by an external light stimulus.
