n-Alkyllithiums were added to alpha,alpha’-disubstituted-1,8-naphthyridines in non-polar solvents Such as Et2O-hexane mixtures. In polar solvents such as THF, alkyllithium acts as a base rather than a nucleophile. Regioselective addition was achieved for substrates capable of five-membered cyclic chelation of the (alkyl)lithium reagent. Substrates with a TBS-protected alcohol as the co-chelating moiety afforded the best combination of yield and regioselectivity. This methodology was Successfully employed in the preparation of two 6-amino-3-pyridinol analogs of pentamethyl-chromanol (PMC), an alpha-tocopherol derivative with its isoprenoid side chain truncated to a methyl group.

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.

Some RNA classes require folding into the proper higher-order structures to exert their functions. Hammerhead ribozyme (HHR) requires a folding conformation stabilized by tertiary interaction for full activity. A rationally engineered HHR was developed that was inactive, but could be activated by a synthetic RNA-binding ligand, naphthyridine carbamate tetramer with Z-stilbene linker (Z-NCTS). Binding of Z-NCTS could induce the formation of an active folding structure and thereby restore ribozyme activity, where Z-NCTS acts as a molecular glue to bring two isolated RNA loops into contact with each other. Next, we designed a Z-NCTS-responsive genetic switch using the HHR sequence inserted into the 3′ untranslated region as a cis-acting element. We demonstrated that the rationally designed ribozyme switch enabled regulation of gene expression by Z-NCTS and was functional in mammalian cells.

New derivatives of 2,7-naphthyridine-3-carboxylic acid were synthesized. We report the hydrolysis, chlorination, alkylation, and amination of the 2,7-naphthyridine esters 1, 2. A series of Schiff’s bases 8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h, 8i, 8j, 9a, 9b, 9b’, 9c, 9d, 9e were produced by treating the obtained hydrazides 6 and 7 with aromatic aldehydes. The anticancer activities of the obtained derivatives were examined. Eighteen of the 24 newly synthesized compounds were qualified by the National Cancer Institute NCI (Bethesda, MD, USA) for in vitro screening against 60 different human tumor cell lines. The most active compound 8i was evaluated against a 60-cell panel at five concentration levels and proved to be most sensitive towards central nervous system cancer (SF-539), with GI50=0.70 mu mol, total growth inhibition=5.41 mu mol, and LC50=53.7 mu mol.

Amine-imine tautomerization in 5-amino-7-(pyrrolidin-1-y1)-2,4,4-trimethy1-1,4-dihydro-1,6-naphthyridine-8-carbonitrile (APNC) has been studied using the B3LYP, CAM-B3LYP and wB97XD with 6-311++G(d,p) basis set. Optimum molecular geometries, electronic properties, energetics and electronic densities of these systems have been discussed and compared with the available experimental data. Investigation reveals that one tautomer (the amine tautomer) dominates the gas phase. The photochromic properties of APNC and its two imine tautomers have been studied at the elected DFT-functionals and basis set. The interconversion Al to 12/13 is predicted to occur photochemically. The NLO properties were also evaluated and discussed. (C) 2017 Elsevier B.V. All rights reserved.

New 1,8-naphthyridine-3-carboxylic acid derivatives were designed, synthesized and evaluated for their in vivo antihistaminic activity on guinea pig trachea by using chlorpheniramine as the standard drug. It was found that compound 5a1 displayed a promising bronchorelaxant effect in conscious guinea pigs using the in vivo model. A molecular docking study was performed to understand the molecular interaction and binding mode of the compounds in the active site of the H1 receptor. Furthermore, in silico computational studies were also performed to predict the binding modes and pharmacokinetic parameters of these derivatives. Prior to the start of experimental lab work, PASS software was used to predict the biological activities of these compounds. An in silico PASS, Swiss ADME assisted docking approach was found to be suitable to derive and synthesize effective antihistaminic agents for the present study.

The effect of structural modulation on a series of donor-acceptor (D-A) copolymers (1-7), comprising of thieno[3,2-b]thiophene (TT) donor and thiazole-flanked different bis-amide-functionalized acceptor units, has been explored. Structural functionalization has been performed by incorporating aromatic rings in the bis-amide-functionalized bipyrrolylidene-2,2 ‘(1H,1 ‘ H)-dione (BPD) (1) acceptor unit, and six D-A copolymers containing isoindigo (2), azaisoindigo (3), benzoisoindigo (4), benzoazaisoindigo (5), 1,5-naphthyridine-BPD (6), and 1,8-naphthyridine-BPD (7) as acceptor units are designed. Density functional theory has been employed to understand the impact of structural modulation on geometrical, optoelectronic, charge transport, and photovoltaic properties of the copolymers. The higher proportion of N-heteroatom in copolymers 3, 6, and 7 leads to low-lying highest occupied molecular orbital (lowest unoccupied molecular orbital) levels and thus improves their air stability and open-circuit voltage. The computed optical absorption in the visible range (602-754 nm) ensures that the studied compounds can efficiently harvest photon energy. The ratio of charge transfer rate (K-CT) and charge recombination rate (K-CR) at donor/PC61BM interfaces of structurally tuned copolymers are found to be similar to 10(7) to 10(22) times higher than 1/PC61BM. The maximum predicted power conversion efficiency by Scharber diagram could reach up to similar to 8% for 3, 6, and 7. The calculated results shed light on the fact that the structural modulation of bis-amide-functionalized D-A copolymers can efficaciously lead to enhanced air stability and photovoltaic performance.

2-(4-Methoxyphenyl)-1-oxo-1,2-dihydro-1,6-naphthyridine-4-carboxamide (4c) underwent Hofmann rearrangement with iodobenzene diacetate in methanol to give the corresponding 4-amino compound (6c). This, when reacted with 2,4-pentanedione and then hot phosphoryl chloride (attempted Combes synthesis) gave a new heterocyclic system, 6-(4-methoxyphenyl)-2-methylpyrido[3,2-c]pyrrolo[2,3-e]azocin-7(6H)-one (9c). This showed typical pyrrole-type reactivity at the 3-position. Alternatively, an attempt to convert the 4-NH2 in 6c to 4-OH by diazotization gave, instead, a [1,2,3]triazolo[1,5-a]pyridine-3-carboxaldehyde (16c). The same series of reactions on a benzo analog, 2-methyl-1-oxo-1,2-dihydrobenzo[b][1,6]naphthyridine-4-carboxamide (4a), gave the same results. (c) 2005 Elsevier Ltd. All rights reserved.

Based on Rhodamine B, two Al3+/Cu2+-selective chemosensors were synthesized, which display a high selectivity for Al3+ and Cu2+ among environmentally and biologically relevant metal ions. A 1,8-Naphthyridine modified rhodamine derivative can detect Al3+ in ethanol with off-on fluorescence behavior, and detect Cu2+ in aqueous solution with colorimetric method. The 8-Hydroxyquinoline-based rhodamine sensor can detect Al3+ in ethanol with both off-on fluorescence and colorimetric methods. The detection mechanism involves a ring-opening process as a consequence of metal complex formation. Job’s plots and a time-of-flight mass spectral study indicated that each chemosensor chelated Al3+/Cu2+ with 1:1 stoichiometry. The binding of the chemosensors and Al3+/Cu2+ is chemically reversible by the addition of F-/EDTA solution, respectively. (C) 2013 Elsevier Ltd. All rights reserved.
