Aggregation induced emission of a new naphthyridine-ethynyl-gold(i) complex as a potential tool for sensing guanosine nucleotides in aqueous media

A new organometallic alkynyl-gold(i) complex capable of exhibiting aggregation induced emission was designed and synthesized. The linear complex structure possesses a central Au(i) atom, bearing two axial ligands: (1) 1,3,5-triaza-7-phosphaadamantane and (2) 2-acetamido-7-ethynyl-1,8-naphthyridine. While the former accounts for its partial solubility in an aqueous environment, the latter acts as a receptor unit for binding guanosine nucleotides and derivatives via multiple hydrogen bonding interactions. At high concentrations, aggregation of the complex was observed by the formation of new absorption (lambda(max) similar to 400 nm) and emission bands (550-700 nm). Formation of aggregates of ca. 60 nm diameter was confirmed by Small Angle X-ray Scattering (SAXS). Disruption of the aggregates in the presence of guanosine derivatives resulted in a ratiometric signal with apparent association constants in the order of 10(5) M-1 and high sensitivity (around 63% signal change) which are, to the best of our knowledge, in line with the highest values recorded for nucleotide sensors based on hydrogen bonding and capable of working in water. Computational studies indicate the presence of additional hydrogen bonding interactions that account for the strong binding of the Au(i) complex to phosphorylated guanosine nucleotides.

Aromatic Helical Foldamers as Nucleophilic Catalysts for the Regioselective Acetylation of Octyl beta-d-Glucopyranoside

Two indolocarbazole-naphthyridine foldamers 2 and 3 that fold into helical conformations were prepared. The 4-(N,N-dimethylamino)pyridine (DMAP) moiety was introduced at one end of the foldamer strands to develop foldamer-based catalysts for the site-selective acylation of polyols. These foldamers adopt helical conformations containing internal cavities capable of binding octyl beta-d-glucopyranoside. The association constants were determined to be 1.9 (+/- 0.1)x10(5) M-1 for 2 and 2.1 (+/- 0.1)x10(5) M-1 for 3 in CH2Cl2 at 25 degrees C. In the presence of DMAP, 2 or 3 as the catalysts, octyl beta-d-glucopyranoside was subjected to acetylation under identical reaction conditions. The DMAP-catalysed reaction afforded the random distribution of the monoacetylates (6-OAc : 4-OAc : 3-OAc : 2-OAc=33 : 24 : 41 : 2). In contrast, foldamers 2 and 3 led to the predominant formation of 6-OAc. The relative distributions were estimated to be 6-OAc : 4-OAc : 3-OAc=88 : 4 : 6 : similar to 0 with 2 and 6-OAc : 4-OAc : 3-OAc : 2-OAc=90 : 3 : 6 : 1 with 3.

1,8-Naphthyridinic fluorescent ‘turn-on’ and ‘turn-off’ chemosensors for detection of F- and Hg2+ ions mimicking INHIBIT molecular logic behaviour

Two new receptors viz. 2-bromoacetamido-5,7-dimethyl-1,8-naphthyridine (1a) and 2-chloroacetamido-5,7-dimethyl-1,8-naphthyridine (1b) containing 1,8-naphthyridine as fluorophore unit have been designed and synthesised. These receptors exhibited very high selectivity for F- ions among the various anions tested such as H2PO4-, OAc-, Cl-, Br-, I-, HSO4-, PF6-, ClO4-, BF4- and NO3- owing to anion-induced deprotonation of the amide NH by F- ions. Among the various cations tested (Na+, Ag+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+, Pb2+ and Mn3+), 1a exhibited selective detection of Hg2+ ions by binding with N1 and N8 atoms of the naphthyridine moiety. Receptor 1a has been explored as a dual-ion detector for F- and Hg2+ ions in two contrasting modes (fluorescence ‘turn-on’ and ‘turn-off’) which is supported by spectroscopic and lifetime measurements. 1a exhibited lower detection limits for F- (0.4 ppm) and Hg2+ (2.4 ppm) ions. These receptors were recovered from anionic species of 1a formed after addition of F- ions by treating with protic solvents such as CH3OH. The mode of binding was also confirmed by spectroscopic and DFT studies. The chemical inputs of F- and Hg2+ ions generate an output which satisfies the condition of two-input INHIBIT logic operators.

Testing a simple approach for theoretical evaluation of radiolysis products in extraction systems. A case of N,O-donor ligands for Am/Eu separation

In this paper, we studied the irradiation and ageing effect on the extraction properties of N, N’-diethyl-N, N’-di(p-hexylphenyl)-1,1′-phenantroline-4,7-dichloro-2,9-dicarboxamide (1) and 2,5,9,12-tetra(n-hexyl)benzo[f] quinolino-[3,4-b]-[1,7]-naphthyridine-6,8(5H,9H)-dione (2) towards Am(III) and Eu(III). DFT calculations were applied to estimate the probable ways of radiolysis for (1) and (2). Degradation products were identified by high-resolution ESI-MS. The interaction of (1) and (2) with the products of solvent radiolysis was established to be the most probable mechanism of ligand destruction.

New 1,4-dihydro[1,8]naphthyridine derivatives as DNA gyrase inhibitors

Owing to the growing need for novel antibacterial agents, we synthesized a novel series of fluoroquinolones including 7-substituted-1-(2,4-difluoropheny1)-6-fluoro-4-oxo-1,4-dihydro[1,8]naphthyridine-3-carboxylic acid derivatives, which were tested against clinically relevant Gram positive and Gram negative bacteria. Chemical structures of the synthesized compounds were identified using spectroscopic methods. In vitro antimicrobial effects of the compounds were determined via microdilution assay. Microbiological examination revealed that compounds 13 and 14 possess a good antibacterial profile. Compound 14 was the most active and showed an antibacterial profile comparable to that of the reference drugs trovafloxacin, moxifloxacin, and ciprofloxacin. A significant MIC90 value (1.95 mu g/mL) against S. aureus ATCC 25923, E. coli ATCC 35218, and E. coli ATCC 25922 was recorded for compound 14. We observed reduced metabolic activity associated with compounds 13 and 14 in the relevant bacteria via a luminescence ATP assay. Results of this assay supported the antibacterial potency of compounds 13 and 14. An E. coli DNA gyrase inhibitory assay indicated that compound 14 is a potent inhibitor of E. coli DNA gyrase. Docking studies revealed that there is a strong interaction between compound 14 and the E. coli DNA gyrase enzyme. Genotoxicity and cytotoxicity evaluations of compounds 13 and 14 showed that compound 14 is non-genotoxic and less cytotoxic compared to the reference drugs (trovafloxacin, moxifloxacin, and ciprofloxacin), which increases its biological importance.

Molecular Dynamics Simulation Study of Binding Affinity of Thieno[2,3-b]benzo[1,8] naphthyridine Derivatives to DNA

DNA binding position and binding affinity of drugs are important information that helps medicinal chemists in synthesis of new drugs. We used molecular docking and molecular dynamics simulation to reveal binding strength of thieno[2,3-b]benzo[1,8]naphthyridine derivatives to DNA. Molecular docking showed that molecules with more steric hindrance select groove position in DNA structure. Other molecules are intercalated between base pairs of GC and AT. Restrained electrostatic potential (RESP) charges, root mean square deviation (RMSD), and total potential analyses were performed. RMSD and total potential analyses showed that all simulations have stability for MMGBSA analysis. Binding affinity of all drugs was derived via MMGBSA analysis. Thermodynamics analysis showed that binding affinity of groove binding drugs is less than that of intercalating ones. Also, it was found that a linear relationship exists between RESP charges and Delta G (pred). Additionally, our results demonstrated the highest affinity for molecules carrying substituent groups of-OCH3 and-CH3.

An unexpected semi-hydrogenation of a ligand in the complexation of 2,7-bispyridinyl-1,8-naphthyridine with Ru-3(CO)(12)

Thermal reaction of 2,7-bis(2-pyridinyl)-l, 8-naphthyridine (bpnp) with Ru-3(CO)(12) in the presence of moisture resulted in the formation of a formate-bridged diruthenium complex [(bpnp-H-3)Ru-2(mu-HCOO)(CO)(4)] (1), in which the ligand was partially hydrogenated. Complex 1 was fully characterized by spectroscopic analyses and X-ray single crystal determination. Regarding the partially reduced ligand in 1, it occurs through a water-gas shift type reduction.
