A new carbon-nitrogen organic semiconductor has been synthesized by pyrolysis of uric acid. This layered carbon-nitrogen material contains imidazole-, pyridine (naphthyridine)-and graphitic-like nitrogen, as evinced by infrared and X-ray photoelectron spectroscopies. Quantum chemistry calculations support that it would consist of a 2D polymeric material held together by hydrogen bonds. Layers are stacked with an interplanar distance between 3.30 and 3.36 angstrom, as in graphite and coke. Terahertz spectroscopy shows a behavior similar to that of amorphous carbons, such as coke, with non-interacting layers. This material features substantial differences from polymeric carbon nitride, with some characteristics closer to those of nitrogen-doped graphene, in spite of its higher nitrogen content. The direct optical band gap, dependent on the polycondensation temperature, ranges from 2.10 to 2.32 eV. Although in general the degree of crystallinity is low, in the material synthesized at 600 C-circle some spots with a certain degree of crystallinity can be found. (C) 2017 Elsevier Ltd.

The oncogenic Epstein-Barr virus (EBV) evades the immune system through limiting the expression of its highly antigenic and essential genome maintenance protein, EBNA1, to the minimal level to ensure viral genome replication, thereby also minimizing the production of EBNA1-derived antigenic peptides. This regulation is based on inhibition of translation of the virally-encoded EBNA1 mRNA, and involves the interaction of host protein nucleolin (NCL) with G-quadruplex (G4) structures that form in the glycine -alanine repeat (GAr)-encoding sequence of the EBNA1 mRNA. Ligands that bind to these G4-RNA can prevent their interaction with NCL, leading to disinhibition of EBNA1 expression and antigen presentation, thereby interfering with the immune evasion of EBNA1 and therefore of EBV (M.J. Lista et al., Nature Commun., 2017, 8, 16043). In this work, we synthesized and studied a series of 20 cationic bis(acylhy-drazone) derivatives designed as G4 ligands. The in vitro evaluation showed that most derivatives based on central pyridine (Py), naphthyridine (Naph) or phenanthroline (Phen) units were efficient G4 binders, in contrast to their pyrimidine (Pym) counterparts, which were poor G4 binders due to a significantly different molecular geometry. The influence of lateral heterocyclic units (N-substituted pyridinium or quinolinium residues) on G4-binding properties was also investigated. Two novel compounds, namely PyDH2 and PhenDH2, used at a 5 mu M concentration, were able to significantly enhance EBNA1 expression in H1299 cells in a GAr-dependent manner, while being significantly less toxic than the prototype drug PhenDC3 (GI(50) > 50 mu M). Antigen presentation, RNA pull-down and proximity ligation assays confirmed that the effect of both drugs was related to the disruption of NCL-EBNA1 mRNA interaction and the subsequent promotion of GAr-restricted antigen presentation. Our work provides a novel modular scaffold for the development of G-quadruplex-targeting drugs acting through interference with G4-protein interaction. (C) 2019 Elsevier Masson SAS.

Visceral leishmaniasis is a parasitic disease that affects, among other areas, both sides of the Mediterranean Basin. The drugs classically used in clinical practice are pentavalent antimonials (Sbv) and amphotericin B, which are nephrotoxic, require parenteral administration, and increasing drug resistance in visceral leishmaniasis has been observed. These circumstances justify the search of new families of compounds to find effective drugs against the disease. Eukaryotic type I DNA topoisomerase (TopIB) has been found essential for the viability of the parasites, and therefore represents a promising target in the development of an antileishmanial therapy. In this search, heterocyclic compounds, such as 1,5-naphthyridines, have been prepared by cycloaddition reaction between N-(3-pyridyl)aldimines and acetylenes and their antileishmanial activity on promastigotes and amastigote-infected splenocytes of Leishmania infantum has been evaluated. In addition, the cytotoxic effects of newly synthesized compounds were assessed on host murine splenocytes in order to calculate the corresponding selective indexes (SI). Excellent antileishmanial activity of 1,5-naphthyridine 19, 21, 22, 24 and 27 has been observed with similar activity than the standard drug amphotericin B and higher selective index (SI > 100) towards L. infantum amastigotes than amphotericin B (SI > 62.5). Special interest shows the 1,5-naphthyridine 22 with an IC50 value (0.58 +/- 0.03 mu M) similar to the standard drug amphotericin B (0.32 +/- 0.05 mu M) and with the highest selective index (SI = 271.5). In addition, this compound shows remarkable inhibition on leishmanial TopIB. However, despite these interesting results, further studies are needed to disclose other potential targets involved in the antileishmanial effect of these novel compounds.

1,8-Naphthyridine derivatives have attracted considerable attention because they are the chief constituent of many compounds which have been isolated from natural sources, with various biological activities. Nalidixic acid, for example, possesses strong antibacterial activity and used mainly for the treatment of urinary tract infections with gram negative pathogens and Gemifloxacin has antimicrobial and antibacterial activities. It is known that (E)- and (Z)-o-(diethylamino)ethyl oximes of 1,8-naphthyridine series have the potential for use as local anesthetics and 1-(2-fluorobenzyl)-3-(2-tolyl)-1,8-naphthyridin-2(1H)-one is used for the treatment of memory disorders, in particular, Alzheimer’s disease. In recent years. research on derivatives of 1,8-naphthyridine has been intensive because these compounds show a wide range of biological activities. 2-Methyl-1,8-naphthyridine-3-carboxylate has been synthesized from ethyl-2-methyl-1,8-naphthyridine-3-carboxylate following two different procedures. The azide on heating with aliphatic and aromatic primaryamines in xylene underwent Curtius rearrangement to furnish the title compounds. They have been screened for their antimicrobial activity.

Transition-metal-catalyzed C-H functionalization of aromatic secondary amides with alkynes mainly undergo C-H/N-H annulation but rarely undergo ortho-alkenylation. It is particularly challenging to selectively realize both oxidative annulation and ortho-alkenylation of aromatic secondary amides with alkynes in the transition-metal-catalysis. In this article, we synthesized fully-substituted 2-pyridones and 2,6-naphthyridine-1,5-diones via C(sp(2))-H functionalization of fumaramides for the first time. Under the Ru-catalysis, fumaramides and 1,2-diaryl ethynes first undergo C-H/N-H annulation leading to the intermediate 2-pyridone with an exocyclic secondary amide, and subsequently undergo the unexpected stereoselective C-H alkenylation to realize fully substituted 2-pyridones bearing an exocyclic anti alkenyl group. On the addition of K2CO3, however, the transformation of fumaramides with 1,2-dialkyl ethyne undergoes two conventional C-H/N-H annulations to provide 2,6-naphthyridine-1,5-diones in high yield. The two procedures can be successfully enlarged to gram-scales without erosion of the yields. In addition, some 2-pyridones and 2,6-naphthyridine-1,5-diones emitting clear ultraviolent and fluorescent light, indicating the potential utility of this work in organic light-emitting materials.

New polynuclear silver(I) complexes with 1,5-naphthyridine (1,5-naph), [Ag(NO3)(1,5-naph)](n) (Ag1), [Ag (CF3COO)(1,5-naph)]n (Ag2) and [Ag(CF3SO3)(1,5-naph)](n) (Ag3) were synthesized by the reaction of the corresponding silver(I) salt and 1,5-naph in ethanol at room temperature. These complexes were characterized by NMR, IR and UV Vis spectroscopy, while their crystal structures were determined by single-crystal X-ray diffraction analysis. In all these complexes, 1,5-naph acts as a bridging ligand between two Ag(I) ions, while the remaining coordination sites are occupied by oxygen atom(s) of the corresponding anion. The antimicrobial efficiency of these silver(I) complexes was evaluated against the broad panel of Gram-positive and Gram-negative bacteria and fungi. The complexes showed good to moderate antibacterial activity with the minimal inhibitory concentration (MIC) values being in the range 2.5-100 mu g/mL (6.5-333.3 mu M), while their antifungal activity against the investigated Candida spp. was significantly higher (MIC = 0.78-6.25 mu g/mL; 2.6-20.8 mu M). Moreover, complexes Ag1 and Ag2 effectively inhibited C. albicans biofilms formation, while Ag1 was also shown to inhibit the formation of mixed C. albicans/Pseudomonas aeruginosa biofilms. Toxicological evaluations on zebrafish (Dario rerio) embryos revealed that all silver(I) complexes could be applied as antifungal agents, whereas Ag3 had the best therapeutic potential showing both the lowest MIC values against the tested Candida strains and the non-toxic in vivo response in the zebrafish embryos at these doses.
