Structure-based design, synthesis, biological evaluation, and molecular docking of novel 10-methoxy dibenzo[b,h][1,6]naphthyridinecarboxamides

10-methoxy dibenzo[b,h][1,6]naphthyridine carboxylic acid was successfully synthesized from 3-methoxyaniline by a new route. By utilizing a structure-based epharmacophore developed from the active site of 3-phosphoinositide-dependent kinase-1, a series of nine novel 10-methoxy dibenzo[b,h][1,6]naphthyridinecarboxamides was synthesized and characterized by different spectral techniques. Three of them are found to be active by screening against A549 cell line and showed significant anticancer activity when compared to a marketed lung cancer drug, pemetrexed. The molecular docking and in silico pharmacokinetic predictions provide detailed understanding for utilizing the dibenzo[b,h][1,6]naphthyridine scaffold in future drug discovery and development of PDK1 inhibitors.

Dichloridobis(7-amino-2,4-dimethyl-1,8-naphthyridine-k(2)N, N ‘)cobalt(II) methanol disolvate

The title compound, [CoCl2(C10H11N3)(2)]center dot 2CH(3)OH, crystallizes with an elongated Co coordination polyhedron in a very distorted octahedral geometry. Both naphthyridine ligands coordinate to the Co atom via two N atoms in a bidentate chelating mode. The remaining coordination sites are occupied by two Cl atoms. Two uncoordinated solvent methanol molecules are hydrogen bonded to the Cl atoms. Additional N-H center dot center dot center dot O, C-H center dot center dot center dot Cl and N-H center dot center dot center dot Cl hydrogen bonds, and pi-pi stacking interactions [centroid-centroid distance 3.664 (4) angstrom], give rise to a three-dimensional network structure.

Double-stranded helicates of Ni(II), Co(II), Fe(II) and Zn(II) with oligo-alpha-naphthyridylamino ligand: Synthesis, structure and properties

By using tetranaphthyridyl-triamine ligand, N-2-(2-(1,8-naphthyridin-7-ylamino)-1,8-naphthyridin-7-yl)-N-7-(1,8-naphthyridin-2-yl)-1,8-naphthyridine-2,7-diamine (H(3)tentra), double-stranded dinuclear helical compounds [M-2(H(3)tentra)(2)(ClO4)(4)] [M = Ni-II (1), Co-II (2), Fe-II (3), Zn-II (4)] were synthesized and structurally characterized. The single X-ray crystal structure of iron(II) complex showed that both of H(3)tentra ligands wrap around the metal-metal axis giving rise to a double-stranded dinuclear helical compound with Fe-Fe separation of ca. 5.326 angstrom. Each ligand uses two nitrogen atoms from two different napthyridine rings, to coordinate one metal centre (Fe or Fe(A)) and therefore, the geometry about the metal ions was described as distorted tetrahedral, with both ligands acting as bisbidentate N4 donors. This distortion is shown by the angles between nitrogen and iron atoms, which range from 80.45(15) to 143.32(14)degrees. Distorted tetrahedral environment was also proposed for the other complexes on the basis of the magnetic measurements and X-ray results. Strong pi-pi interactions were observed for all synthesized double stranded helicates of H(3)tentra ligand. The measured chi T-M values at 300 K for complexes 2 and 3 found larger than the expected values for two high-spin Co(II) with S = 3/2 and for Fe(II) ions with S = 2 and g = 2, which attributed to the unquenched orbital coupling.

Fluorescence turn-on hairpin-probe PCR

A new fluorescence turn-on type of PCR monitoring system(Hpro-PCR) using a hairpin probe and a primer having a tag sequence at the 50 end with the fluorescent molecule 2,7-diamino-1,8-naphthyridine derivative (DANP) has been developed. The Hpro-PCR exploited the modulation of the equilibrium states between the DANP-bound hairpin structure and probe-tag duplex, and the PCR progress alternated the equilibrium state, resulting in the change of fluorescent intensity.

Synthesis, crystal structures, and electronic spectra of (1,8-naphthyridine)Re-I(CO)(3)Cl and [(1,8-naphthyridine)Cu-I(DPEPhos)]PF6

Two 1,8-naphthyridine (nap) metal complexes (nap)Re-I(CO)3CI (1) and [(nap)Cu-I(DPEPhos)]PF6 (2) were synthesized and characterized by NMR-, emission, and absorption spectroscopy, elemental analysis, mass spectrometry, and X-ray structural analysis. In both complexes, the nap ligand coordinates with both N atoms to the metal centre in a bidentate manner. I and 2 exhibit a broad phosphorescence in solid state at T = 300 K, which is completely quenched in solution at r.t. In addition, the gas-phase structures of both complexes were optimized at the B3LYP/6-31G(d,p) level of theory. (c) 2007 Elsevier B.V. All rights reserved.
