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.

Proton transfer reaction and intermolecular interactions in associates of 2,5-dihydroxy-1,8-naphthyridine

Tautomerism in monomers/dimers and association of 2,5-dihydroxy-1,8-naphthyridine was studied at the DFT level recently recommended for studies of noncovalent interactions. Studied dimers are stabilized by double and triple hydrogen-bonding. In some associates the intermolecular proton transfer may take place. Transition state related to the double proton transfer reactions were calculated and discussed in terms of energetics, changes in atomic charges upon association, aromaticity (HOMA), properties of hydrogen bond critical point (QTAIM methodology) and geometry change during this reaction. It was found that double proton transfer is supported by third hydrogen bond or by weak secondary interaction. Some protons in transition states are shared between two basic atoms, while other are covalently bound only to one of them. The said process leads to replacement of secondary interactions of attractive character to repulsive and vice versa. Overall, results suggest that in subjected compound the triple hydrogen-bonded associate may be in equilibrium with double hydrogen-bonded dimer.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 13822-56-5. Safety of 3-(Trimethoxysilyl)propan-1-amine.

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).

A FACILE AND CONVENIENT SYNTHESIS OF NAPHTHYRIDINOYL PYRAZOLES

The reaction of naphthyridine hydrazide (4) with each of the different beta-keto esters like ethyl 2-chloroacetoacetate (5), ethyl benzoylacetate (6) and ethyl 4-chloroacetoacetate (7) and with ethoxymethylenemalonic ester (8), independently, in ethanol, resulted in the formation of condensed products 2-chloro-3-[4-oxo-1,4-dihydro-[1,8] naphthyridine-3-carbonyl hydrazono]-butyric acid ethyl ester (9), 3-[(4-oxo-1,4-dihydro-[1,8] naphthyridine-3-carbonyl)-hydrazono]-3-phenyl propionic acid ethyl ester (10), 4-chloro-3-[(4-oxo-1,4-dihydro-[1,8] naphthyridine-3-carbonyl)-hydrazono]-butyric acid ethyl ester (11) and 2-[N-(6-bromo-4-oxo-1,4-diydro-[1,8] naphtyiridine-3-carbonyl-hydrazinomethylene)-malonic acid diethyl ester] (12) respectively. Each of these on heating with diphenyl ether yielded the corresponding cyclized products 3-(4-chloro-3-methyl-5-oxo-4,5-dihydro-pyrazole-1-carbonyl)-1H-[1,8] naphthyridin-4-one (13), 3-(5-oxo-3-phenyl-4,5-dihydro-pyrazole-1-carbonyl)-1H-[1,8] naphthyridine-4-one (14), 3-(3-chloromethyl-5-oxo-4,5-dihydropyrazole-1-carbonyl)-1H-[1,8] naphthyridine-4-one (15) and 3-(4-chloro-3-methyl-5-oxo-4, 5-dihydropyrazole-1-carbonyl)-1H-[1, 8] naphthyridin-4-one (16). Alternatively, treatment of naphthyridine hydrazide (4) with each of the beta-keto esters 5,6 & 7 and with EMME (8) directly in diphenylether at 250 degrees as one-pot reaction, gave the final products 13,14,15 & 16 in good yields.

One-pot synthesis and antimicrobial activity of novel naphthyridine derivatives

A one-pot synthetic route was developed to synthesise novel naphthyridine derivatives from amino acids and a series of new naphthyridines was prepared and characterised by IR, (1)H NMR, MS and elemental analysis. The preliminary bioassay results reveal that they have medium antimicrobial activity against Bacillus subtilis, Staphylococcus aureus, Aspergillus, Escherichia coli and Monilia albican. The compounds containing aliphatic amino acids have greater bioactivity than that of those containing aromatic amino acids against Bacillus subtilis and Staphylococcus aureus.

An effective HIV-1 integrase inhibitor screening platform: Rationality validation of drug screening, conformational mobility and molecular recognition analysis for PFV integrase complex with viral DNA

As an important target for the development of novel anti-AIDS drugs, HIV-1 integrase (IN) has been widely concerned. However, the lack of a complete accurate crystal structure of HIV-1 IN greatly blocks the discovery of novel inhibitors. In this work, an effective HIV-1 IN inhibitor screening platform, namely PFV IN, was filtered from all species of INs. Next, the 40.8% similarity with HIV-1 IN, as well as the high efficiency of virtual screening and the good agreement between calculated binding free energies and experimental ones all proved PFV IN is a promising screening platform for HIV-1 IN inhibitors. Then, the molecular recognition mechanism of PFV IN by its substrate viral DNA and six naphthyridine derivatives (NRDs) inhibitors was investigated through molecular docking, molecular dynamics simulations and water-mediated interactions analyses. The functional partition of NRDs IN inhibitors could be divided into hydrophobic and hydrophilic ones, and the Mg2+ ions, water molecules and conserved DDE motif residues all interacted with the hydrophilic partition, while the bases in viral DNA and residues like Tyr212, Pro214 interacted with the hydrophobic one. Finally, the free energy landscape (FEL) and cluster analyses were performed to explore the molecular motion of PFV IN-DNA system. It is found that the association with NRDs inhibitors would obviously decrease the motion amplitude of PFV IN-DNA, which may be one of the most potential mechanisms of IN inhibitors. This work will provide a theoretical basis for the inhibitor design based on the structure of HIV-1 IN. (C) 2017 Elsevier Inc. All rights reserved.

Homoleptic mono- and dinuclear complexes of platinum(II) with 1,8-naphthyridine

Two unprecedented, homoleptic Pt-1,8-naphthyridine complexes have been prepared and characterized. Reaction between 1,8-naphthyridine (napy) and a platinum(II) precursor leads to a mononuclear homoleptic platinum(II) complex with stoichiometry [Pt(napy)(4)](OTf)(2). On the contrary, reaction between napy and a dinuclear platinum(III) precursor produces instead a rare example of a dinuclear, homoleptic, tetracationic platinum(II) complex with stoichiometry [Pt-2(napy)(4)](OTf)(4). Crystal structures of both complexes have been obtained. The redox behavior of the dinuclear complex has been studied by cyclic voltammetry, in order to establish its suitability as model precatalyst for organometallic reactions exploiting the Pt(II)/Pt(IV) or Pt(II)/Pt(III) manifold.
