The title complex, [Ag-4(C7H5O3)(2)(C8H6N2)(4)(C7H6O3)(4)], lies about an inversion centre and has a unique tetranuclear structure consisting of four Ag-I atoms bridged by four N atoms from two 1,8-naphthyridine (napy) ligands to form an N: N’-bridge and four O atoms from two salicylate ( SA) ligands to form an O: O’-bridge. The Ag atoms have distorted octahedral coordination geometry. The centrosymmetric Ag-4 ring has Ag – Ag separations of 2.772 ( 2) and 3.127 ( 2) angstrom, and Ag – Ag – Ag angles of 107.70 ( 4) and 72.30 ( 4) degrees. All SA hydroxy groups take part in intramolecular O – H center dot center dot center dot O hydrogen bonding. In the crystal packing, the napy rings are oriented parallel and overlap one another. These pi-pi interactions, together with weak intermolecular C – H center dot center dot center dot O contacts, stabilize the crystal structure.

Synthesis and comparative solvatochromic studies of simple and donor acceptor benzimidazole incorporated naphthyridine systems

Benzimidazo[1,2-a]benzo[g]-1,8-naphthyridine (NB-1) and its donor-acceptor analog, 11-morpholino-benzimidazo[1,2-a]benzo(g)-1,8-naphthyridine-6-carbonitrile, (NB-2) have been synthesized and investigated for their optical and solvatochromic properties. Absorption and emission maxima of the push-pull chromophore, NB-2 were red shifted in comparison to NB-1 lacking in donor-acceptor motif. Both systems are highly fluorescent (phi = 0.74-0.84) and exhibit positive solvatochromism. Using solvatochromic shift method, we estimated 2 fold higher dipole moment in the excited state for NB-2 over NB-1. High degree of electronic charge redistribution in NB-2 seems to be responsible for its optical spectral red shifts and higher dipole moments compared to NB-1.

Targeting multiple G-quadruplex-forming DNA sequences: Design, biophysical and biological evaluations of indolo-naphthyridine scaffold derivatives

It is well recognized that the non-canonical DNA structures known as G-quadruplexes (G4s) have a potential anticancer significance and several compounds have been discovered and evaluated as promising G4 binders with anticancer activity. Here, starting from a promising hit with an indolo-naphthyridine scaffold, a small series of five indolo-naphthyridine based derivatives have been designed and evaluated as G4-targeting compounds. FRET biophysical studies were performed on multiple DNA G4 structures, leading to the identification of a multi-target G4 stabilizer with a slight preference for the c-KIT1 and a good G4 over duplex selectivity. The good affinity of this compound against c-KIT1 G4 was also confirmed by SPR and MST experiments, while biological assays revealed its cytotoxic activity on tumour cells. Finally, Molecular Dynamics simulations helped to elucidate the stabilization effect of the selected compound against the c-KIT1 G4. (C) 2019 Elsevier Masson SAS. All rights reserved.

Design and synthesis of novel substituted naphthyridines as potential c-Met kinase inhibitors based on MK-2461

Two series of novel 1,5-naphthyridine and 1,6-naphthyridine derivatives were designed and synthesized based on the c-Met kinase inhibitor MK-2461 under the guidance of scaffold hopping strategy. All were tested on c-Met kinase and in vitro anti-tumor activities against Hela and A549 cell lines. The results indicated that 1,6-naphthyridine was a more promising c-Met inhibitory structure core compared with 1,5-naphthyridine. Among them, 26b and 26c showed the best enzymic and cytotoxic activities. The western blot experiments implied that the cytotoxic activity of 26c might be partially through suppressing the phosphorylation of c-Met kinase. (C) 2015 Elsevier Ltd. All rights reserved.

A novel naphthyridine tetramer that recognizes tandem G-G mismatches by the formation of an interhelical complex

We have designed and synthesized a novel naphthyridine tetramer, p-NCTB, for the recognition of tandem guanine-guanine (G-G) mismatches in DNA. p-NCTB possesses a p-biphenyl linker connecting two naphthyridine carbamate dimer (NCD) moieties that recognize G-G mismatches. p-NCTB preferentially bound to tandem G-G mismatches in dCGGG/dCGGG over dCGG/dCGG. Two dCGGG/dCGGG sites were simultaneously recognized and were noncovalently cross-linked via the formation of inter- and intrastrand complexes with p-NCTB. The intrastrand binding was more favorable, which could allow p-NCTB to bind selectively to a sequence containing multiple dCGGG/dCGGG sites.

We designed a novel naphthyridine-based supporting ligand involving two silyl coordinating moieties at 2,7-positions, t-BuNBSi, for the synthesis of dinuclear metal complexes. Reaction of a ligand precursor t-BuNBSi(H)(2) (1) with Ru-3(CO)(12) gave a di-mu-hydridodiruthenium(II,II) complex (t-BuNBSi) Ru-2(mu H)(2)(CO)(4) (2). Photoirradiation to 2 resulted in the formation of a diruthenium(I,I) complex (t-BuNBSi)Ru-2(CO)(6) (3). The Si-Ru-Ru-Si linkage of 2 takes a zigzag arrangement, whereas that of 3 adopts a roughly linear one.
