The 1,8-naphthyridine group of compounds have gained special attention of researchers on account of their demonstrating a variety of interesting biological activities. A wide range of biological properties establishes them as potent scaffolds in therapeutic and medicinal research. The broad spectrum of activities primarily includes antimicrobial, antiviral, anticancer, anti-inflammatory, and analgesic activities. 1,8-Naphthyridine derivatives have also exhibited potential applications in neurological disorders such as Alzheimer’s disease, multiple sclerosis, and depression. In addition, these synthetic derivatives have been found to possess activities such as anti-osteoporotic (alpha(v)beta(3) antagonists), anti-allergic, antimalarial, gastric antisecretory, bronchodilator, anticonvulsant, antihypertensive, platelet aggregation inhibition, anti-oxidant, EGFR inhibition, protein kinase inhibition, ionotropic agent, beta-3 antagonist, MDR modulator, adenosine receptor agonist, adrenoceptor antagonist, and pesticide activities. In spite of the widespread application of the 1,8-naphythyridine scaffolds, only a limited number of review articles are available till date. In this review, we attempt to compile and discuss the key data available in the literature for the multiple biological activities of 1,8-naphthyridine derivatives, in a chronological manner. This review compilation (with 199 references) may be helpful in understanding the diverse biological properties of 1,8-naphthyridines and provide insights into their mechanism of action. This may direct future research in the synthesis of new derivatives and exploring this scaffold for other possible biological activities.

These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. If you like, you can also browse other articles about this kind.

Discrimination of base mismatches from normal Watson-Crick base pairs in duplex DNA constitutes a key approach to the detection of single nucleotide polymorphisms ( SNPs). We have developed a sensor for a surface plasmon resonance (SPR) assay system to detect G-G, A-A, and C-C mismatch duplexes by employing a surface upon which mismatch-binding ligands (MBLs) are immobilized. We synthesized a new MBL consisting of 2,7-diamino-1,8-naphthyridine (damND) and immobilized it onto a CM5 sensor chip to carry out the SPR assay of DNA duplexes containing a single-base mismatch. The SPR sensor with damND revealed strong responses to all C-C mismatches, and sequence-dependent C-T and T-T mismatches. Compared to ND- and naphthyridine-azaquinolone hybrid (NA)-immobilized sensor surfaces, with affinity to mismatches composed of purine nucleotide bases, the damND-immobilized surface was useful for the detection of the mismatches composed of pyrimidine nucleotide bases.

Novel 3-amino-1-(3,5-dimethyl-1H-pyrazol-1-yl)-2,7-naphthyridines were synthesized on the basis of monohydrazides derived from 2,7-naphthyridines. The cyclization of 3-chloro-1-(3,5-dimethyl-1H-pyrazol-1-yl)-2,7-naphthyridine with hydrazine hydrate gave the tricyclic pyrazolo[3,4-c]-2,7-naphthyridine, which was used to prepare the novel heterocyclic system pyrimido[1′,2′:1,5]pyrazolo[3,4-c]-2,7-naphthyridine.

Two novel linear hexanuclear nickel complexes [Ni-6(mu(6)-dpznda)(4)Cl-2](PF6)(2) (1) and [[Ni-6(mu(6)-dpznda)(4)(NCS)(2)](PF6)(2) (2) (H(2)dpznda = N-2,N-7-di(pyrazin-2-yl)-1,8-naphthyridine-2,7-diamine) were synthesized and structurally characterized. Both the two complexes consist of a linear metal chain and four supporting ligands which are helically wrapped around the metal core. The single crystal X-ray structural analysis showed that the complex 1 belonged to rhombohedral system, space group R-3 with a = b = 34.2051(8),c = 20.7751(5) angstrom, V = 21050.2(9) angstrom(3) and Z = 9. Direct-current magnetic susceptibility measurements showed weak antiferromagnetic interactions with coupling parameters of g = 2.04 and J = -8.27 cm(-1) for 1 and g = 2.02 and J = -12.62 cm(-1) for 2, respectively ( = -J (S) over cap (1)(S) over cap (2), S1 = S2 = 1). The decrease of magnetic moments at low temperature was partly attributed to ZFS. The electrochemical study on complex 1 shows rich features and facility to reduction in its cyclic voltammogram by displaying four reversible redox couples at E-1/2 = +0.01,-0.29,-0.64 and -0.73 V (vs. Ag/AgCl).

The apical sodium dependent bile acid transporter (ASBT) is the main transporter to promote re-absorption of bile acids from the intestinal tract into the enterohepatic circulation. Inhibition of ASBT could increase the excretion of bile acids, thus increasing bile acid synthesis and consequently cholesterol consumption. Therefore, ASBT is an attractive target for developing new cholesterol-lowering drugs. In this report, a series of 1-(2,4-bifluoropheny1)-7-dialkylamino-1,8-naphthyridine-3-carboxamides were designed as inhibitors of ASBT. Most of them demonstrated potency against ASBT transport of bile acids. In particular, compound 4a(1) was found to have the best activity, resulting in 80.1% inhibition of ASBT at 10 mu mol/L.

Bacillus sp. are well-known biocontrol agents against various fungal plant pathogens. The present work was conducted for characterization of antagonistic Bacillus sp., isolated from tomato rhizosphere, and its control mechanisms against Fusarium oxysporum f. sp. lycopersici. A collection of 49 Bacillus isolates was obtained from the rhizosphere of tomato plants from infested field. Dual culture antagonism assay was carried out to assess the potential role of the strains against the pathogen. The evaluation of the strains was done for their antifungal ability and plant growth promoting properties including beta-1,3-glucanase, protease, chitinase, ammonia, siderophore, hydrogen cyanide, IAA and biofilm formation. Strain B44, identified as Bacillus sp. based on ribotyping (Accession no. MG779639), which exhibited maximum number of antifungal properties tested, was selected for further study. The strain was capable of producing hydrolytic enzymes such as beta-1,3-glucanase (15.61 U ml(-1) min(-1)), protease (1608.15 U ml(-1) min(-1)), and chitinase (129 U ml(-1) min(-1)), volatiles and non-volatile metabolites. Volatiles were extracted by solid phase micro extraction (SPME) technique. The major compounds identified by GC-MS analysis were 1,2-benzenedicarboxylic acid (23.99%), 6-undecylamine (6.61%), 2-methyloctacosane (5.91%), 9-octadecenoic acid (5.13%) and 1-tetradecanamine, N,N-dimethyl (5.05%). The prominent compounds identified by UPLC-MS were tert-butyl difluorophosphine (31.45%), 5-(4,4,5,5-tetramethyl-1, 3, 2-dioxaborolan-2-yl)-3,6-dihydro-2H-pyran (14.76%), 6-bromo-4-tert-butyl-1,1-dimethyl-1,2-dihydronaphthalene (8.35%), 2-amino-N-butyl-1,8-naphthyridine-3-carboxamide (6%), N,N-diethyl-2-[(ethylamino)methyl]-3-phenyloxirane-2-sulfonamide (5.12%). The isolate showed approx. 36% reduction in disease incidence in tomato plant under green house conditions and could serve as an efficient agent for biocontrol of wilt disease in tomato.

On the basis of the very interesting pharmacological properties shown by the 5-amino[1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamide derivatives 1, previously described by us, we have now prepared the 5-aminoimidazo[1,2-a][1,8]naphthyridine-6-carboxamide derivatives 2a-o (a new structural class) whose tricyclic system is isosteric to that of compounds 1. Both compounds 2 and some new properly substituted compounds 1 (1f-k) now synthesized were tested in vivo for their analgesic and anti-inflammatory activities: on the whole, compounds 2 showed notable analgesic properties, whereas many compounds 1 exhibited a very potent anti-inflammatory activity, coupled to scarce analgesic activity. All the effective compounds proved to be completely devoid of acute gastrolesivity (gastric damage) in rats (at the 200 mg kg(-1) oral dose). (C) 2009 Elsevier Masson SAS. All rights reserved.
