1,8-Naphthyridine Based Artificial Receptors for Selective Monosaccharide Binding in Water

1,8-Naphthyridine based bi-bracchial macrocyclic 2 and cage-type macrobicyclic receptor 3 bind monosaccharides in water under physiologically relevant conditions through a combination of hydrophobic, electrostatic and hydrogen bonding interactions. The dissociation constants (K-d) for the complexes between 1,8-naphthyridine receptors 1-3 with a variety of neutral and negatively charged monosaccharides in water were determined by fluorimetric and UV/vis titration. The observed values are in the range from similar to 0.3 to >= 10 mM, and are similar to the K-d reported for lectin/monosaccharide complexes. Among the monosaccharide substrates tested, receptor 2 showed the strongest binding affinity for sialic acid (K-d = similar to 0.3 mM), a monosaccharide that plays many important roles in a wide variety of physiological and pathological processes. Interestingly, receptors 2 and 3 display the ability to discriminate between closely related monosaccharide substrates by opposite variation of the fluorescence emission intensity.

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 132-64-9, in my other articles.

A highly selective fluorescent sensor for Cd2+ based on a new diarylethene with a 1,8-naphthyridine unit

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.

Theoretical investigations of the realization of sky-blue to blue TADF materials via CH/N and H/CN substitution at the diphenylsulphone acceptor

A series of derivatives based on 10,10-dimethyl-5,10-dihydro-pyrido[4,3-b][1,6] naphthyridine-diphenylsulphone (DMDHNP-DPS) named 1a was designed with CH/ N and H/ CN substitution at the DPS acceptor unit to obtain blue thermally activated delayed fluorescence (TADF) materials. The parent molecule 1a was chosen from our previous report after CH/ N substitution at the DMAC donor fragment. The highest occupied molecular orbitals (HOMOs) and the lowest unoccupied molecular orbitals (LUMOs) were largely distributed over the DMDHNP donor and DPS acceptor units, respectively, resulting in a slight overlap between the HOMO-LUMO and hence a smaller singlet-triplet energy gap (DEST). Steric hindrance caused a large dihedral angle (E821-891) between the plane of the electrondonating DMDHNP unit and the electron-accepting DPS unit in the substituted derivatives. Calculated results indicated that the DEST values of H/ CN substituted derivatives were smaller than those of the corresponding CH/ N derivatives which were favorable for the reverse intersystem crossing (RISC) process from the lowest excited triplet states (T1) to the lowest excited singlet (S1) states and ultimately to the ground state (S0) causing delayed emission. The emission wavelengths (lem) of all the designed molecules were found to be in the range of 397-497 nm. The incorporation of the -NQatom or the -CN group at the ortho and meta positions of DPA reduced the transition energies from LUMO -HOMO in the S1 states, resulting in a red-shift. Moreover, the lem values displayed a more substantial bathochromic-shift as the number of -NQatoms or -CN groups increased. The two of the designed molecules (1h and 1i) showed sky-blue emission (494 nm and 497 nm), and the four of the investigated compounds (1c, 1d, 1f, and 1g) displayed blue emission (416 nm, 447 nm, 437 nm, and 432 nm, respectively) indicating that these investigated derivatives were efficient sky-blue to blue TADF candidates. Among all the investigated derivatives, the smaller DEST values for the designed systems 1f (0.03 eV) and 1g (0.02 eV) and appropriate lem values of 437 nm and 432 nm make them excellent candidates for blue TADF materials. Our theoretical investigation might offer hints for the construction of efficient blue TADF-based organic light emitting diodes (OLEDs) in the future.

Pharmacokinetic evaluation of C-3 modified 1,8-naphthyridine-3-carboxamide derivatives with potent anticancer activity: lead finding

To develop naphthyridine derivatives as anticancer candidates, pharmacokinetic (PK) evaluations of 10 novel derivatives of 1,4-dihydro-4-oxo-1-proparagyl-1,8-naphthyridine-3-carboxamide, with potent anticancer activity were done using in vitro ADME (absorption, distribution, metabolism, excretion) and pharmacokinetic-pharmcodynamic (PK/PD) assays. Only derivatives 5, 6, 9 and 10 showed better metabolic stability, solubility, permeability, partition coefficient and cytochrome P450 (CYP) inhibition values. PK of derivatives 5, 6, 9 and 10 in rat showed comparable PK profile for derivative 5 (C-0 = 6.98 mu g/mL) and 6 (C-0 = 6.61 mu g/mL) with no detectable plasma levels for derivatives 9 and 10 at 5.0 mg/kg i.v. dose. PK/PD assay of derivatives 5 and 6 in tumor-bearing mice (TBM) showed comparable PK but tumor plasma index (TPI) of derivative 6 (4.02) was better than derivative 5 (2.50), suggesting better tumor uptake of derivative 6. Derivative 6, as lead compound, showed highest tumor growth inhibition (TGI) value of 33.6% in human ovary cancer xenograft model.

1,8,10-Trisubstituted anthracenyl hydrocarbons: Towards versatile scaffolds for multiple-H-bonded recognition arrays

In this work, we describe the synthesis of 1,8,10-trisubstituted anthracenyl scaffolds that, bearing boronic acid functionalities, can act as multiple H-bonding donor systems. The trisubstituted anthracenyl derivatives are synthesized following two main synthetic pathways. Whereas in the first approach trisubstituted anthracenyl derivatives are prepared through the regioselective addition of the relevant organomagnesium nucleophile to 1,8-dichloroanthraquinone, in the second avenue a triflate-bearing anthracene is prepared by reduction of the anthraquinone into the anthrone precursor and functionalized through metal-catalysed cross-coupling reactions. Complementary studies of the Na2S2O4-mediated reduction of 1,8-dichloroanthraquinone allowed to shed further light on the possible mechanism of formation of the anthrone precursor, suggesting the presence of a cis-diol intermediate undergoing antiperiplanar elimination. Solid-state X-ray diffraction investigations of the bisboronic acids show that the molecules self-assemble into dimers through the formation of four H-1-bonds established between the anti-syn conformers of the boronic acid moieties. H-1-NMR titrations between bisboronic acids and tetra H-bond acceptor, diisoquinolino-naphthyridine, showed a significant shift of the -B(OH)(2) proton resonances, suggesting the presence of H-bonding interactions between both molecules.

Synthesis and anti-tubercular activity of fused thieno-/furo-quinoline compounds

A simple route for preparation of 4-substituted thieno/furo[2,3-c]quinoline compounds is reported in this paper. These compounds were synthesized by using Suzuki coupling between appropriate boronic acid and 2-iodoaniline, followed by reaction with diverse aldehydes in the presence of a catalytic amount of FeCl3. Naphthyridine analogues were also prepared in order to demonstrate the efficacy of the developed method. Further anti-tubercular activity screening of the molecules was undertaken, wherein compounds bearing a fused furo[2,3-c][1,8]naphthyridine skeleton displayed highest activity. The best MIC (minimum inhibitory concentration) value of 5.6 mu mol was obtained for 4-(4-methoxyphenyl)furo[2,3-c][1,8]naphthyridine, which is found to be superior to the existing first line anti-tubercular drug ethambutol (7.6 mu mol).
