An efficient synthesis of 1-oxo-1,2-dihydrobenzo[b][1,6]naphthyridine-4-carbonitriles

Ethyl alpha-(dimethylaminomethylene)-2-cyanomethyl-4-phenylquinoline-3-carboxylate (2) as new synthons directed to 1-oxo-1,2-dihydrobenzo[b][1,6]naphthyridine-4-carbonitriles was obtained by the condensation of ethyl 2-cyanomethyl-4-phenylquinoline-3-carboxylate (1) and N,N-dimethylformamide dimethyl acetal (DMFDMA). Reaction of this enamine with primary amines (3) in HOAc-DMF at 120 degrees C then affords 2-substituted 1-oxo-1,2-dihydrobenzo[b][1,6]naphthyridine-4-carbonitrile derivatives (4) in good yields by a tandem additioneliminationcyclization reaction.

A novel naphthyridine tetramer that recognizes tandem G-G mismatches by the formation of an interhelical complex

We have designed and synthesized a novel naphthyridine tetramer, p-NCTB, for the recognition of tandem guanine-guanine (G-G) mismatches in DNA. p-NCTB possesses a p-biphenyl linker connecting two naphthyridine carbamate dimer (NCD) moieties that recognize G-G mismatches. p-NCTB preferentially bound to tandem G-G mismatches in dCGGG/dCGGG over dCGG/dCGG. Two dCGGG/dCGGG sites were simultaneously recognized and were noncovalently cross-linked via the formation of inter- and intrastrand complexes with p-NCTB. The intrastrand binding was more favorable, which could allow p-NCTB to bind selectively to a sequence containing multiple dCGGG/dCGGG sites.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13822-56-5, in my other articles.

Antilipolytic effects of 1,8-naphthyridine derivatives beta-adrenoceptor antagonists in rat white adipocytes

The rat fat cell beta-adrenoceptors were investigated by studying the effects of new 1,8-naphthyridine derivatives synthesized starting from 7-amino-2-chloro-3-phenyl-1,8- naphthyridine on lipolysis induced by isoprenaline, and alprenolol. Lipolysis induced by isoprenaline agonist was competitively antagonized by the 1,8-naphthyridine analogue with a 7-hydroxy-2-(4′-methoxybenzylamine)-6-nitro-3-phenyl substituent designated as 3. In contrast, 10, 50, and 100 mu m of 7-methoxy and 7-ethoxy derivatives did not modify the concentration- response curve of isoprenaline. A rightward shift of the curve was, however, observed with 50 mu m of a 7-methoxy-2-(4 methoxybenzylamine)-6-amino-3-phenyl substituent designated as 10. The selective beta 1-AR antagonist, 7-hydroxy-4-morpholinomethyl-2-piperazino-1,8-naphthyrid ine slightly reduced isoprenaline- induced lipolysis only at high doses. Alprenolol-mediated lipolytic effect was antagonized by derivative 3, 10 and the selective beta 3-AR antagonist SR 59,230A, but resistant to the selective beta 1-AR antagonist 7-hydroxy-4-morpholinomethyl- -2-piperazino-1,8-naphthyridine. The results provide preliminary pharmacological evidence for the antilipolytic effect of the newly synthesized 1,8-naphthyridine derivatives on rat fat cells. The analogues designated as 3 and 10 were the most potent antagonists of this series.

Novel annulated products from aminonaphthyridinones

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.

Lophocladines, bioactive alkaloids from the red alga Lophocladia sp.

Lophocladines A (1) and B (2), two 2,7-naphthyridine alkaloids, were isolated from the marine red alga Lophocladia sp. collected in the Fijian Islands. Their structures were deduced on the basis of high-resolution mass spectra and one- and two-dimensional NMR spectroscopy. Lophocladine A (1) displayed affinity for NMDA receptors and was found to be a delta-opioid receptor antagonist, whereas lophocladine B (2) exhibited cytotoxicity to NCI-H460 human lung tumor and MDA-MB-435 breast cancer cell lines. Immunofluorescence studies indicated that the cytotoxicity of lophocladine B (2) was correlated with microtubule inhibition. This is the first reported occurrence of alkaloids based on a 2,7-naphthyridine skeleton from red algae.

Cyclometalated Ir-Sn Construct for Cyanosilylation

Two cyclometalated compounds [(IrCl)-Cl-III{(2-biphenylene-1,8-naphthyridine-kappa C,N}(eta (5)-pentamethylcyclopentadienyl)] (1) and [(IrCl)-Cl-III{(2-(2-N-Methyl-pyrrolyl-1,8-naphthyridine-kappa C,N}(eta (5)-pentamethylcyclopentadienyl)] (2) containing naphthyridine based ligands have been synthesized in high yield. Insertion of SnCl2 to a terminal Ir-Cl bond of 1 affords the mixed Ir-SnCl3 compound [(IrSnCl3)-Sn-III{(2-biphenylene-1,8-naphthyridine-kappa C,N}(eta (5)-pentamethylcyclopentadienyl)] (3). The heterobimetallic compound 3 is shown to be an excellent catalyst for a variety of cyanosilylation reactions. A cooperative mechanism has been proposed which involves the simultaneous activation of aldehyde and cyanide precursor by Sn and unbound naphthyridine nitrogen.

Proton transfer reaction and intermolecular interactions in associates of 2,5-dihydroxy-1,8-naphthyridine

Tautomerism in monomers/dimers and association of 2,5-dihydroxy-1,8-naphthyridine was studied at the DFT level recently recommended for studies of noncovalent interactions. Studied dimers are stabilized by double and triple hydrogen-bonding. In some associates the intermolecular proton transfer may take place. Transition state related to the double proton transfer reactions were calculated and discussed in terms of energetics, changes in atomic charges upon association, aromaticity (HOMA), properties of hydrogen bond critical point (QTAIM methodology) and geometry change during this reaction. It was found that double proton transfer is supported by third hydrogen bond or by weak secondary interaction. Some protons in transition states are shared between two basic atoms, while other are covalently bound only to one of them. The said process leads to replacement of secondary interactions of attractive character to repulsive and vice versa. Overall, results suggest that in subjected compound the triple hydrogen-bonded associate may be in equilibrium with double hydrogen-bonded dimer.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 13822-56-5. Safety of 3-(Trimethoxysilyl)propan-1-amine.

Synthesis of fully substituted naphthyridines: a novel domino four-component reaction in a deep eutectic solvent system based on choline chloride/urea

The diversity-oriented synthesis of a naphthyridine scaffold has been demonstrated via a novel domino four-component reaction. The syntheses were achieved by reacting a diamine, 1,1-bis(methylthio)-2-nitroethylene, 2-aminoprop-1-ene-1,1,3-tricarbonitrile, and various carbonyl compounds using a deep eutectic solvent (DES), based on choline chloride/urea, thus providing a new class of poly-functionalized fused naphthyridine derivatives with the concomitant formation of three new rings and six sigma bonds. The reaction conditions were mild and did not require additional base catalysts. Given the inexpensive, nontoxic, and recyclable nature of the DES, these reaction conditions are simple and highly environmentally friendly. (C) 2015 Elsevier Ltd. All rights reserved.
