Stereospecific synthesis and redox properties of ruthenium(II) carbonyl complexes bearing a redox-active 1,8-naphthyridine unit

Two stereoisomers of cis-[Ru(bpy)(pynp)(CO)Cl]PF(6) (bpy = 2,2′-bipyridine, pynp 2-(2-pyridyl)-1,8-naphthyridine) were selectively prepared. The pyridyl rings of the pynp ligand in [Ru(bpy)(pynp)(CO) Cl](+) are situated trans and cis, respectively, to the CO ligand. The corresponding CH(3)CN complex ([Ru(bpy)(pynp)(CO) (CH(3)CN)](2+)) was also prepared by replacement reactions of the chlorido ligand in CH(3)CN. Using these complexes, ligand-centered redox behavior was studied by electrochemical and spectroelectrochemical techniques. The molecular structures of pynp-containing complexes (two stereoisomers of [Ru(bpy)(pynp) (CO)Cl]PF(6) and [Ru(pynp)(2)(CO)Cl]PF(6)) were determined by X-ray structure analyses.

Homogeneous Perdehydrogenation and Perhydrogenation of Fused Bicyclic N-Heterocycles Catalyzed by Iridium Complexes Bearing a Functional Bipyridonate Ligand

Homogeneous perdehydrogenation of saturated bicyclic 2,6-dimethyldecahydro-1,5-naphthyridine and perhydrogenation of aromatic 2,6-dimethyl-1,5-naphthyridine with release and uptake of five molecules of H-2 are efficiently achieved by iridium complexes bearing a functional bipyridonate ligand. Successive perhydrogenation and perdehydrogenation of 2,6-dimethyl-1,5-naphthryridine using a single iridium complex also proceed with the reversible inter-conversion of the catalytic species, depending on the presence or absence of H-2.

An Unexpected 4,5-Diphenyl-2,7-naphthyridine Derivative with Aggregation-Induced Emission and Mechanofluorochromic Properties Obtained from a 3,5-Diphenyl-4H-pyran Derivative

For a specific fluorescent molecule, the increase of molecular conformation distortion is beneficial to endow it with aggregation-induced emission (AIE) and mechanofluorochromic (MFC) properties. Herein, 3,5-diphenyl-4H-pyran derivative5and 4,5-diphenyl-2,7-naphthidine derivative7with highly twisted conformations were synthesized. For compound5, although the introduction of phenyl rings with large steric hindrance at 3 and 5 positions of the 4H-pyran skeleton realized the transformation from aggregation-induced quenching (ACQ)-active molecule to AIE-active molecule, it only showed a low-contrast MFC activity. Compound7was accidentally obtained from compound5andn-butylamineviaa ring-opening and subsequent intramolecular ring-closing mechanism. Compound7was confirmed to have a highly twisted molecular conformation by the crystal structural analysis and exhibited AIE activity originated from the restriction of intramolecular rotation. Furthermore, compound7exhibited reversible high-contrast MFC activity. Upon grinding, the change of solid-state fluorescence color from orange to yellow was confirmed to be due to the partial destruction of crystal structure. This work provides new ideas for the design and synthesis of novel AIE-active and MFC-active fluorescent molecules based on ACQ-active parent molecules.

Supramolecular salts of 5,7-dimethy1-1,8-naphthyridine-2-amine and acids through classical H-Bonds and other intermolecular interactions

This article demonstrates 5,7-dimethyl-1,8-naphthyridine-2-amine based organic salts formation of crystalline solids 1-9, in which the acidic units have been integrated via a variety of non-covalent bonds. Addition of equivalents of the acidic units to the solution of 5,7-dimethyl-1,8-naphthyridine-2-amine generates the single protonated species which direct the anions. The nine compounds crystallize as their salts with the acidic H transferred to the aromatic N of the 5,7-dimethy1-1,8-naphthyridine-2-amine. In 2, 3, 4, and 7 the methyl substituted N-rings were protonated, while others were protonated at the NH2 substituted N-ring. All salts have been characterized via IR, mp, EA and XRD technique. The major driving force for the salt formation is attributed to the classical H-bonds from 5,7-dimethyl-1,8-naphthyridine-2-amine and the acids. Other extensive intermolecular interactions also play great functions in space association of the molecular assemblies in the relevant crystals. The common R-2(2)(8) graph set has been observed in all salts due to the H-bonds and other intermolecular interactions, except 2, 4, and 6. For the synergistic interactions of the various non-covalent bonds, all salts displayed 3D structures. (C) 2017 Elsevier B.V. All rights reserved.

Targeting Expanded Repeats by Small Molecules in Repeat Expansion Disorders

Recent technological advancements in genetic analysis have allowed for the consecutive discovery and elucidation of repeat expansion disorders: diseases caused by the abnormal expansion of repeat sequences in the genome. Many of these repeat expansion disorders are neurodegenerative movement disorders. Radical cures for these disorders have yet to be established. Although conventional treatments for repeat expansion disorders have mainly targeted the abnormal mRNA and proteins encoded by the affected genes, therapeutic approaches targeting repeat DNA, the root cause of repeat disorders, is also being explored in current research. In particular, a small molecule has been found that binds to abnormally expanded CAG repeats, the cause of Huntington’s disease, and shortens them. Such small molecules targeting nucleic acids are expected to be developed into groundbreaking therapeutic drugs capable of ameliorating the symptoms of repeat expansion disorders and preventing their onset.

Rhenium Complexes with a Pyridinyl-Naphthyridine Ligand: Synthesis, Characterization, and Catalytic Activity

Treatment of [Re2(CO)8(CH3CN)2] with 2,7-dipyridinyl-1,8-naphthyridine (bpnp) thermally provided mononuclear [(N,N-bpnp)Re(CO)3Cl] (1). Further reaction of 1 with rhenium carbonyls yielded ortho-metallation dinuclear rhenium complex 2. Both complexes were characterized by spectroscopic analyses and single-crystal X-ray determination. Complex 1 also reacted with [PdMeCl(COD)] and [Ir(COD)Cl]2 by means of ortho-metallation to yield the corresponding heterodinuclear species. Complex 2 appears to be an excellent precatalyst to promote the insertion of terminal alkynes into acetoacetates, which subsequently undergo cyclization to form 2-pyranones.

Molecular receptors for monosaccharides: di(pyridyl)naphthyridine and di(quinolyl)naphthyridine

The recognition capabilities of two molecular receptors 2,7-di(3′-pyridyl)-1,8-naphthyridine (DPN) and 2,7-di(3′-quinolyl)-1,8-naphthyridine (DQN) toward monosaccharides in chloroform were evaluated. Both DPN and DQN possess a naphthyridine core moiety, in which two pyridinic nitrogen atoms serve as the proton acceptors. Attached to the C2 and C7 positions of naphthyridine are two identical arms, each of which consists of pyridine (DPN) or quinoline (DQN) moiety that also acts as the proton acceptor. The arrangement of hydroxyl groups in monosaccharides offers the proton donors complementary to the proton acceptors of DPN (or DQN) to form a quadruply hydrogen bonds complex. The binding processes were studied by UV-vis, fluorescence and H-1 NMR spectrophotometric titrations as well as electrospray ionization mass spectroscopy. The binding strength between DPN (or DQN) and examined monosaccharides was comparable to that for man other hydrogen-bonding host molecules previously reported. (c) 2005 Elsevier Ltd.

Synthesis of Naphthyridine Carbamate Dimer (NCD) Derivatives Modified with Alkanethiol and Binding Properties of G-G Mismatch DNA

A series of new DNA binding molecules NCD-Cn-SH (n = 3, 4, 5, and 6) is reported, which possesses the NCD (naphthyridine carbamate dimer) domain selectively binding to the G-G mismatch in the 5′-CGG-3’/5′-CGG-3′ sequence and a thiol moiety, which undergoes spontaneous dimerization to (NCD-Cn-S)(2) upon oxidation under aerobic conditions. The S-S dimer (NCD-Cn-S)(2) produced the 1:1 binding complex with improved thermal stability. The dimer binding to the CGG/CGG DNA showed higher positive cooperarivity than the binding of monomer and previously synthesized NCTn derivative. The dimerization of NCD-Cn-SH was selectively accelerated on the CGG repeat DNA but not on the CAG repeat DNA.
