Development of 13H-benzo[f]chromeno[4,3-b][1,7]naphthyridines and their salts as potent cytotoxic agents and topoisomerase I/II alpha inhibitors

A novel series of 35 angularly fused pentacyclic 13H-benzo[f]chromeno[4,3-b][1,7]naphthyridines and 13H-benzo[f]chromeno[4,3-b][1,7]naphthyridin-5-ium chlorides were designed and synthesized. Their cytotoxic activities were investigated against six human cancer cell lines (NCIH23, HCT15, NUGC-3, ACHN, PC-3, and MDA-MB-231). Among all screened compounds; 28, 30, 34, 35, 46, 48, 52, and 53 compounds exhibited potent cytotoxic activities against all tested human cancer cell lines. Further, these potent lead cytotoxic agents were evaluated against human Topoisomerase I and II alpha inhibition. Among them, the compound 48 exhibited dual Topoisomerase I and II alpha inhibition especially at 20 mu M concentrations the compound 48 exhibited 1.25 times more potent Topoisomerase II alpha inhibitory activity (38.3%) than the reference drug etoposide (30.6%). The compound 52 also exhibited excellent (88.4%) topoisomerase I inhibition than the reference drug camptothecin (66.7%) at 100 mu M concentrations. Molecular docking studies of the compounds 48 and 52 with topo I discovered that they both intercalated into the DNA single-strand cleavage site where the compound 48 have van der Waals interactions with residues Arg364, Pro431, and Asn722 whilst the compound 52 have with Arg364, Thr718, and Asn722 residues. Both the compounds 48 and 52 have pi-pi stacking interactions with the stacked DNA bases. The docking studies of the compound 48 with topo IIa explored that it was bound to the topo II alpha DNA cleavage site where etoposide was situated. The benzo[f]chromeno[4,3-b][1,7]naphthyridine ring of the compound 48 was stacked between the DNA bases of the cleavage site with pi-pi stacking interactions and there were no hydrogen bond interactions with topo II alpha.

Syntheses of Geometrical Isomers for Comparison of Properties Caused by Steric and Electronic Effects in Carbonylruthenium(II) Complexes

Both stereoisomers of the novel ruthenium complex [Ru(tpy)(pynp)(CO)](2+) containing 2,2′:6′,2 ”-terpyridine (tpy), a terminal carbonyl, and the unsymmetrical bidentate naphthyridine ligand 2-(2-pyridyl)-1,8-naphthyridine (pynp) were selectively synthesized. In addition, two more ruthenium complexes [Ru(ptpy)(pynp)(CO)](2+) containing 4′-phenyl-2,2′:6′,2 ”-terpyridine (ptpy) instead of tpy were also prepared. These complexes were fully characterized and their molecular structures were determined by X-ray crystallography. Some obvious differences between the isomers were revealed by the structural, computational, and spectroscopic results. Furthermore, redox properties and carbonyl ligand-based reactions of these four complexes were examined to evaluate the steric and electronic effects of the other ligands on the carbonyl reactivity. Both effects, based on the structural differences, exerted a large influence on the reactivity.

Synthesis and insecticidal activities of 1,8-naphthyridine derivatives

1,8-Naphthyridines (NAP) are biological important scaffolds in bioactive molecules design. By hybrid of NAP with neonicotinoid core structure, nine novel NAP derivatives were synthesized and subjected to insecticidal activities evaluation. Some of the compounds showed excellent insecticidal activity against cowpea aphids (Aphis craccivora) with LC50 values ranging from 0.011 mmol/L to 0.067 mmol/L. The results indicated that 1,8-naphthyridine can be used as insecticidal structure for further modification.

The synthesis of 4-aryl-2-(3-(2-(trifluoromethyl)phenyl)-1,8-naphthyridin-2-yl)phthalazin-1(2H)-ones was performed by cyclization of 2-hydrazinyl-3-(2-(trifluoromethyl)phenyl)-1,8-naphthyridine with 2-aroylbenzoic acids in ethanol containing a catalytic amount of concentrated sulfuric acid under solid state conditions. All these synthesized compounds (8a-h) were screened for their in vitro antibacterial activity against gram-positive bacteria such as (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli) and also evaluated for their antifungal activity against Aspergillus Niger and Helmenthosphorium oryzae fungal strains. Some of the products demonstrate good antibacterial activity and moderate antifungal activity. In predominantly, 8b, 8d, 8g, and 8h compounds showed good to excellent antibacterial and antifungal activities.

1,8-Naphthyridine-Derived Ni2+/Cu2+-Selective Fluorescent Chemosensor with Different Charge Transfer Processses

A highly fluorescent chemosensor based on 1,8-naphthyridine with high sensitivity and selectivity toward Ni2+/Cu2+ over other cations both in aqueous solution over a wide pH range (4-10) and in cellular environments was developed. Counteranions such as acetate, sulfate, nitrate, and perchlorate have no influence on the detection of such metal ions. Ethylenediamine showed high selectivity toward the in situ-prepared Cu2+ complex over the Ni2+ complex, which can be applied to distinguish Ni2+ and Cu2+. The Ni2+-induced fluorescence on off mechanism was revealed to be mediated by intramolecular charge transfer from the metal to the ligand, while that by Cu2+ involves intramolecular charge transfer from the ligand to the metal, as confirmed by picosecond time-resolved fluorescence spectroscopy and time-dependent density functional theory calculations.

Probing the single pair rupture force of supramolecular quadruply hydrogen bonding modules by nano-adhesion measurement

Studying quadruply hydrogen bonding (QHB) module interactions in materials matrices presents a significant challenge because a wide variety of non-covalent interactions may be relevant. Here we introduce a method of surface modification with DeUG (7-deazaguanine urea), DAN (2,7-diamido-1,8-naphthyridine) and UPy (2-ureido-4[1H]-pyrimidone) modules to form self-assembled monolayers (SAMs) on a glass surface. The QHB interactions under mechanical stress were investigated by measuring adhesion force using PS-DAN (DAN modified polystyrene), PBMA-DeUG (DeUG modified poly butyl methacrylate) and PBA-UPy (UPy modified poly butyl acrylate) as adhesion promoters. A mechanical lap-shear test was used to evaluate the fracture resistance of QHB heterocomplexes. The maximum load at fail showed that QHB interaction contributed significantly (72%) to overall adhesion. For the QHB modified glass surface, using a polymer modified with its complementary QHB partner greatly facilitated their pairing efficiency, up to 40% for DAN-DeUG. A general method from which single pair ruptures force of QHB modules could be obtained using thermodynamic data obtained from solution chemistry was proposed. Using this method, the single pair rupture force for UPy-UPy was measured as 160 pN, and the single pair rupture force for DAN-DeUG was obtained as 193 pN.

QSAR study of substituted 1,3,4-oxadiazole naphthyridines as HIV-1 integrase inhibitors

A linear quantitative structure activity relationship (QSAR) model is presented for modeling and predicting the inhibition of HIV-1 integrase. The model was produced by using the stepwise multiple linear regression technique on a database that consists of 67 recently discovered 1,3,4-oxadiazole substituted naphthyridine derivatives. The developed QSAR model was evaluated for statistical significance and predictive power. The key conclusion of this study is that valence connectivity index order 1, lowest unoccupied molecular orbital and dielectric energy significantly affect the inhibition of HIV-1 integrase activity by 1,3,4-oxadiazole substituted naphthyridine derivatives. The selected physicochemical descriptors serve as a first guideline for the design of novel and potent antagonists of HIV-1 integrase. (C) 2010 Elsevier Masson SAS. All rights reserved.
