The treatment of 2-(benzo[d] thiazol-2-yl)-3-(pyridin-4-yl) acrylonitrile (6) with malononitrile afforded 1-amino-3-(pyridin-4-yl)-3H-pyrido[2,1-b][1,3] benzothiazole-2,4-dicarbonitrile (7), which was allowed to react with a variety of reagents to provide pyrimido[5′, 4′: 5,6] pyrido[2,1-b][1,3] benzothiazole 8, 9 and [1,3] benzothiazolo[3,2-a][1,8] naphthyridine 10, 15 derivatives.

We designed a novel naphthyridine-based supporting ligand involving two silyl coordinating moieties at 2,7-positions, t-BuNBSi, for the synthesis of dinuclear metal complexes. Reaction of a ligand precursor t-BuNBSi(H)(2) (1) with Ru-3(CO)(12) gave a di-mu-hydridodiruthenium(II,II) complex (t-BuNBSi) Ru-2(mu H)(2)(CO)(4) (2). Photoirradiation to 2 resulted in the formation of a diruthenium(I,I) complex (t-BuNBSi)Ru-2(CO)(6) (3). The Si-Ru-Ru-Si linkage of 2 takes a zigzag arrangement, whereas that of 3 adopts a roughly linear one.

Background: The prevalence of morbidity and mortality due to infections from parasitic worms and protozoa is on rise especially in third world countries. The situation is further worsened by drug resistant microbial pathogens. Objectives: The antimicrobial and anthelmintic activities associated with substituted furfuraldehyde and 1,8-naphthyridine nucleus of nalidixic acid prompted us to synthesize some new quinolone Schiff bases with an aim to obtain potent antibacterial and anthelmintic agents with improved safety and efficacy. Methods: A new series of 1,8 naphthyridine based Schiff bases were designed and synthesized by the reaction of Nalidixic acid methyl ester 1 with hydrazine hydrate in anhydrous condition which yielded 1-ethyl-1,4-dihydro-7-methyl-4-oxo-1,8-naphthyridine-3-carbohydrazide 2. The compound 2 was further treated with several furfural aldehydes to furnish the desired Schiff bases (3a-k). The in vitro antibacterial activity of Schiff bases was investigated against four Gram positive and four Gram negative bacterial strains. The newly prepared Schiff bases were also tested for their anthelmintic activity against Pheritima posthuma and Perionyx excavatus. Results: Chemical structures and identity of the prepared compounds were confirmed by their spectral data. Overall, Schiff bases (3a-k) showed good antimicrobial activity and interestingly five compounds exhibited more potent inhibitory effect than the standard drug Ampicillin against S. aureus, B. cereus, E. faecalis, S. epidermidis, E. coli, S. typhi and S. dysenteriae. Schiff bases also exhibited significant anthelmintic activity as indicated by their mean paralyses time (min) of 7.07-16.49, and 11.23-20.46 min against Perionyx excavatus and Pheritima posthuma in comparison to the 8.23 and 12.58 min shown by standard drug-Albendazole. Conclusion: It could be proposed that substitution of aromatic ring at C-5 of furfuryl heterocyclic ring in the Schiff bases produce compounds with promising antibacterial and anthelmintic actions.

Herpes Simplex Virus (HSV) infections are among the most common human diseases. In this work, we assess the structural features and electronic properties of a series of ten 1-hydroxyacridone derivatives (1a-j) recently described as a new class of non-nucleoside inhibitors of Herpes Simplex Virus-1 (HSV-1). Based on these molecules, we applied rigid analogue and isosteric replacement approaches to design and synthesize nine new 3H-benzo[b]pyrazolo[3,4-h]-1,6-naphthyridine derivatives (2a-i). The biological and computational results of these new molecules were compared with 1-hydroxyacridones. An inhibitory profile was observed in 10-Cl substituted 3H-benzo[b]pyrazolo[3,4-h]-1,6-naphthyridine derivative (2f), which presents the same substituent at the analogous position of 1-hydroxyacridone derivative (1b). The structure-activity relationship (SAR) studies pointed out the 10-position next to nitrogen atom as important for the anti-HSV-1 profile in the pyrazolo-naphthyridine derivatives tested, which reinforced the promising profile for further experimental investigation. The most potent acridone and pyrazolo-naphthridine derivatives were also submitted to an in silico ADMET screening in order to determine their overall drug-score, which confirmed their potential antiviral profile.

Stepwise changes of functional oxo and amino groups in 1,8-naphthyridines to modify the supramolecular architecture have been carried out. The first example of a naphthyridine helix has been found and its structure established by X-ray crystallography. The design is based on hydroxy and amido tautomeric naphthyridines which crystallize in dimers or catemers, one of them attaining helicity. The most stable tautomer present in all the compounds discussed in this paper, as well as the formation of hydrogen-bonded dimers or catemers, was established by X-ray crystallography and rationalized with theoretical calculations.

Three-component reaction of an alpha-isocyanoacetamide 7, an homoallylamine 8 and an aldehyde 9 in methanol at room temperature provides oxa-bridged tricycle 4 in good to excellent yield as a mixture of two separable diastereoisomers. In this one-pot multicomponent process, one C-N, one C-O and three C-C bonds are formed with concomitant creation of five asymmetric centers and three rings. Fragmentation of epoxy-tetrahydronaphthyridine 4 affords differentially substituted 5,6,7,8-tetrahydro-1,7-naphthyridine (5, 6) depending on the reaction conditions, providing thus additional structural diversity. A one-pot three-component synthesis of 5,6,7,8-tetrahydro-1,7-‘naphthyridine (6) from 7, 8 and 9 is also documented. (c) 2005 Elsevier Ltd. All rights reserved.

Purpose The aim of this study was to prepare tosufloxacin tosylate (TFLX) and hydroxypropyl-beta-cyclodextrin (HP-beta-CD) inclusion complexes by solution-enhanced dispersion with supercritical CO2 (SEDS) and optimize process parameters, in vitro dissolution evaluation, and determination of inclusion sites. Methods The effects of operating pressure, operating temperature, drug concentration, and solution flow rate on the particle size and morphology of the inclusion complex were analyzed by a single factor design experiment. The SEDS-prepared inclusion complex was characterized by TG/DSC, XRD, SEM, FT-IR, H-1 NMR, 2D-ROESY, and MD and measured for in vitro dissolution, solubility, and antibacterial activity. Results The optimum drug concentration was 40 mg/mL and pressure 16 MPa, temperature 35 degrees C, and solution flow rate 1 mL/min; under this condition, the mean particle size of the inclusion complex was 1.91 mu m. All characterization results confirmed the formation of an amorphous inclusion complex and the sites where TFLX and HP-beta-CD bind through the H-bond were located on the aromatic B ring, pyrrolidine, and naphthyridine ring protons. Furthermore, the solubility of the inclusion complex (489.87 mu g/mL) was significantly higher than that of TFLX, and the dissolution rate of TFLX increased from the initial 13.99 to 61.04% in ultrapure water. In vitro study showed that the inclusion complex maintained the antibacterial effect of TFLX. Conclusion TFLX/HP-beta-CD inclusion complex prepared by manipulating SEDS process conditions could significantly improve the dissolution and solubility of the water-insoluble TFLX.

In this study, we developed a donor-pi-acceptor-pi-donor-type thermally activated delayed fluorescence (TADF) emitter (NyDPAc) using 1,5-naphthyridine as a core moiety. NyDPAc exhibited a high horizontal dipole ratio and thus a high external quantum efficiency (20.9%) even at a relatively low photoluminescence quantum yield (57%). 1,5-naphthyridine as an electron acceptor represents a promising core moiety for efficient TADF materials.

An efficient and environmentally benign synthetic protocol has been developed for the synthesis of benzo[c]pyrazolo[2,7]naphthyridine derivatives through regioselective multi-component on-water reaction of isatin, malononitrile and 3-aminopyrazole. The Knoevenagel condensation of isatin with malononitrile resulted in the formation of arylidene, which subsequently underwent Michael addition with 3-aminopyrazole followed by basic hydrolysis, cyclization, decarboxylation and aromatization to give the target naphthyridines in good to excellent yields. The one-pot multi-component protocol was also employed to obtain the said naphthyridines in a lower yield (10-15%) than obtained by basic hydrolysis of spiro-intermediates. The present study shows attractive features such as the use of water as a green solvent, short reaction time, reduced waste products and transition metal free C-C and C-N bond formation. The structures of the synthesized derivatives were established through FTIR, H-1-NMR, C-13-NMR spectroscopy and ESI-mass spectrometry.
