A simple and convenient sequential one-pot synthesis of 1,2,3,4-tetrahydrobenzo[b][1,6] naphthyridines has been developed. The reductive amination of 2-chloro-3-formylquinolines with various amines in the presence of sodium borohydride provided the corresponding secondary amines in high yields. Further, a sequential one-pot reaction involving N-allylation and intramolecular Heck type 6-exo-trig cyclization was performed on the secondary amines to afford a range of desired 1,2,3,4-tetrahydrobenzo[b][1,6]naphthyridine derivatives in good to high yields.

New Advances in Chemical Research, April 2021.The transformation of simple hydrocarbons into more complex has revolutionised modern synthetic chemistry. This type of reactivity has quickly become one of the cornerstones of modern catalysis .13331-27-6, Name is 3-Nitrophenylboronic acid, SMILES is C1=C(C=CC=C1[N+]([O-])=O)B(O)O, belongs to naphthyridine compound.

1,8-Naphthyridine derivatives related to 17 (ITH4012), a neuroprotective compound reported by our research group, have been synthesized. In general, they have shown better inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) than most tacrine derivatives previously synthesized in our laboratory. The compounds presented an interesting neuroprotective profile in SH-SY5Y neuroblastoma cells stressed with rotenone/oligomycin A. Moreover, compound 14 (ethyl 5-amino-2-methy1-6,7,8,9-tetrahydrobenzo[b][1,8]naphthyridine-3-carboxylate) also caused protection in cells stressed with okadaic acid (OA) or amyloid beta 1-42 peptide (A beta(1-42)). Interestingly, compound 14 prevented the OA-induced PP2A inhibition, one of the enzymes implicated in tau dephosphorylation. This compound also exhibited neuroprotection against neurotoxicity elicited by oxygen and glucose deprivation in hippocampal slices. Because these stressors caused neuronal damage related to physiopathological hallmarks found in the brain of Alzheimer’s disease (AD) patients, we conclude that compound 14 deserves further in vivo studies in AD models to test its therapeutic potential in this disease.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. I hope my blog about 13331-27-6 is helpful to your research. HPLC of Formula: https://www.ambeed.com/products/13331-27-6.html.

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.

We describe the synthesis of eight novel putative mono- and bis-DNA intercalators from a common precursor, 6-bromoindolo[1,2-b][2,7]naphthyridine-5,12-dione. Of these new indoloquinones, our data indicate that two are most likely DNA mono-intercalators, but weaker than ethidium bromide, and two others are DNA bis-intercalators. Our indoloquinones are inactive against mammalian topoisomerase II. [GRAPHICS] .

The affinity profiles for the bovine adenosine receptors, A(1) and A(2A), of a series of 1,8-naphthyridine derivatives were quantitatively analyzed using physicochemical and structural parameters of the substituents, present at varying positions of the molecules. The derived significant correlation, for bovine A(1) receptor, suggested that a R-1 substituent having a higher van der Waals volume, a R-2 substituent being a hydrogen-bond donor and a R-3 substituent able to transmit a higher field effect are helpful in augmenting the pK(i) of a compound. Similarly the study, pertaining to bovine A(2A) receptor, revealed that a less bulky substituent at R-2 and a strong electron-withdrawing substituent at R-3 are desirable in improving the binding affinity of a compound while substituents at R-1 remain insignificant to any interaction.

Nitropyridylnaphthalene is the central intermediate for the synthesis of naphthonaphthyridine and benzo–carboline. Whereas the Cadogan reaction gives the carboline, transformation of the nitro group to iodo followed by oxidation and cyclization results in an iodonium salt. A twofold Pd-catalyzed amination leads to the naphthyridine.

A naphthyridine carbamate tetramer (NCT8) is a synthetic compound, which selectively binds to nucleic acids containing CGG/CGG sequence. Although NCT8 is a promising compound for a wide range of DNA and RNA based biotechnology such as modulation of specific gene expression, little is known about its behavior in human cells. In the present study, we investigated the changes induced in gene expression by NCT8. Genes differentially expressed in the presence of NCT8 in HeLa cells were identified by whole-transcriptome analysis. The whole-transcriptome analysis showed that NCT8 significantly induced up-regulation of specific genes, whose promoter region has GC-rich sequence. (C) 2017 Elsevier Ltd. All rights reserved.
