The 1,6-naphthyridine motif is a multivalent scaffold in medicinal chemistry presenting various bioactivities when properly substituted. By incorporating a cyclic urea pharmacophore into the 1,6-naphthyridine framework through conformationally constraining the 7,8-positions, the resulting 1H-imidazo[4,5-h][1,6]naphthyridin-2(3H)-one was identified as a new class of c-Met kinase inhibitor. A comprehensive SAR study indicated that an N-1 alkyl substituent bearing a terminal free amino group, a hydrophobic substituted benzyl group at the N-3 position and the tricyclic core were essential for retaining effective Met inhibition of the 1H-imidazo[4,5-h][1,6] naphthyridin-2(3H)-one chemotype. Further introduction of a 4′-carboxamide phenoxy group at the C-5 position significantly improved the potency. The best c-Met kinase inhibitory activity was exemplified by 2t with an IC50 = 2.6 mu M, which also displayed effective inhibition against TPR-Met phosphorylation and the proliferation of the BaF3-TPR-Met cells at low micromolar concentrations.

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.

Influences of enhanced conjugated framework on the structures and photophysical properties of BF2 core compounds containing 1,8-naphthyridine derivative: A DFT/TD-DFT study

We have studied the structural and photophysical characteristics of a series of 1,8-naphthyridine-BF2 compounds in detail. The purpose of quantum-chemical calculations is to study the effect of electron-withdrawing (electron-donating) substituents and core-frame conjugation on the optical properties. The solvent effects are researched in toluene, CH2Cl2, THF, acetone, CH3CN and CH3OH solutions, respectively, by polarizable continuum model (PCM). The results show that the HOMO, LUMO, energy gaps, IP and EA of BF2 core compounds 1-3 containing 1,8-naphthyridine change regularly due to the different degrees of conjugation framework. However, the influence of the substituent changes on these molecules is not significant. The results also show that the maximum absorption wavelengths of the complexes exhibit blue shift as the polarity of the solvent increases from toluene to CH3OH. In addition, the absorption wavelengths of the studied molecules are red-shifted to some extent due to the increased conjugation in the central framework. All calculations reveal that the naphthyridine-BF2 compounds are expected to be a useful luminescent material for OLEDs.

Ligand effects on the structure, mixed-valence sites and magnetic properties of novel pentanickel string complexes

We report the syntheses, characterization, electronic structures and magnetic properties of four redox pairs of novel nickel-extended metal-atom chain (EMAC) complexes containing pyridine-, naphthyridine- and sulfonyl-containing ligands (H(2)Tspnda and H(2)Mspnda) (1-2 and 5-6). We further study the corresponding phenyl-substituted ligands (H(2)Tsphpnda and H(2)Msphpnda) (3-4 and 7-8) to examine the details of ligand effects. The X-ray structure of one-electron-reduced [Ni-5](9+) complexes shows shorter Ni-Ni bond distances (2.2646(6) for 1, 2.2943(7) for 3, 2.2436(11) for 5 and 2.2322(8) angstrom for 7) in comparison with an average Ni-Ni distance of 2.3187(8) angstrom for these complexes, indicative of a partial metal-metal bond interaction in the mixed-valence [Ni-2](3+) (S = 3/2) unit. The most striking result is that the [Ni-2](3+) site migrates from Ni(1)-Ni(2) to Ni(2)-Ni(3) when we replace the p-tolyl-sulfonyl group with methyl-sulfonyl group. These complexes present a rare example of the effect of crystal packing on the symmetric molecular structure yielding unsymmetric electronic distribution. Cyclic voltammetry measurements show four reversible redox waves and display the lower potentials of the [Ni-5](9+) complexes. These unusual lower potentials facilitate one-electron oxidation of these four complexes to [Ni-5](10+)-core forms. We applied the magnetic susceptibility and EPR measurements to examine the magnetic properties of these four [Ni-5](9+)-core pentanickel complexes and study the bonding nature of these mixed-valence [Ni-2](3+) units. Indeed, the results of EPR measurements reflect the migration of the mixed-valence site and the change of symmetry. Surprisingly, the oxidized [Ni-5](10+) counterparts behave differently: complex 2 exhibits an antiferromagnetic interaction with J = -13.59 cm(-1) between the two terminal Ni ions, while the others (4, 6 and 8) display diamagnetic properties as all of the Ni2+ ions are in low-spin (S = 0) states. These three complexes, to the best of our knowledge, are the first examples of all Ni2+ ions in a null spin configuration for pentanickel chains. Even though the structures of these complexes are similar to each other, their corresponding electronic structure and oxidized products show drastic changes in their magnetic properties and bonding nature. These differences of the properties and bonding nature of these pentanickel complexes are attributed to the ligand effects.

A slipped-CAG DNA-binding small molecule induces trinucleotide-repeat contractions in vivo

In many repeat diseases, such as Huntington’s disease (HD), ongoing repeat expansions in affected tissues contribute to disease onset, progression and severity. Inducing contractions of expanded repeats by exogenous agents is not yet possible. Traditional approaches would target proteins driving repeat mutations. Here we report a compound, naphthyridine-azaquinolone (NA), that specifically binds slipped-CAG DNA intermediates of expansion mutations, a previously unsuspected target. NA efficiently induces repeat contractions in HD patient cells as well as en masse contractions in medium spiny neurons of HD mouse striatum. Contractions are specific for the expanded allele, independently of DNA replication, require transcription across the coding CTG strand and arise by blocking repair of CAG slip-outs. NA-induced contractions depend on active expansions driven by MutS beta. NA injections in HD mouse striatum reduce mutant HTT protein aggregates, a biomarker of HD pathogenesis and severity. Repeat-structure-specific DNA ligands are a novel avenue to contract expanded repeats. Naphthyridine-azaquinolone specifically binds slipped-CAG DNA intermediates, induces contractions of expanded repeats and reduces mutant HTT protein aggregates in cell and animal models of Huntington’s disease.
