Several 2-amino-6-aryl-1,8-naphthyridines were reported. The cyclocondensation of 2,6-diaminopyridine, 2-bromomalonaldehyde in phosphoric acid resulted in the formation of 2-amino-6-bromo-1,8-naphthyridine, which was converted into 2-amino-6-aryl-1,8-naphthyridines by palladium-catalyzed Suzuki reaction with arylboronic acid. It is shown that the Suzuki coupling with palladium catalyst (Pd-132) could be completed efficiently with lower catalyst loading and good to excellent yields. The title compounds were characterized by NMR spectra and mass spectra.

Two stereoisomers of cis-[Ru(bpy)(pynp)(CO)Cl]PF(6) (bpy = 2,2′-bipyridine, pynp 2-(2-pyridyl)-1,8-naphthyridine) were selectively prepared. The pyridyl rings of the pynp ligand in [Ru(bpy)(pynp)(CO) Cl](+) are situated trans and cis, respectively, to the CO ligand. The corresponding CH(3)CN complex ([Ru(bpy)(pynp)(CO) (CH(3)CN)](2+)) was also prepared by replacement reactions of the chlorido ligand in CH(3)CN. Using these complexes, ligand-centered redox behavior was studied by electrochemical and spectroelectrochemical techniques.

Most N,N-disubstituted 5-amino-N,N-diethyl-9-isopropyl [1,2,4]triazolo[4,3-alpha] [1,8]naphthyridine-6-carboxamides 9 (compounds 9a, c-i) and the N-monosubstituted one 8c were obtained by treating with excess amine the corresponding 5-chloroderivative 7a, which was in turn prepared by cyclocondensation of the 2,4-dichloro-N,N-diethyl-1,8-naphthyridine-3-carboxamide (4a) with isobutyrohydrazide. Compounds 8a,b and 9b,j-m were obtained according with the methods shown in Scheme 1. The above now synthesized compounds, along with the previously described 8d and 8e, were tested for their anti-inflammatory, analgesic and antipyretic properties, and most compounds also for their effect on spontaneous mice locomotor activity and their acute gastrolesivity in rats. Several compounds showed potent anti-inflammatory and/or analgesic activities, and all the compounds tested proved to be completely lacking in acute gastrolesivity. In many cases compounds 8 and 9 produced hypothermic effect, usually at high doses. On the whole, the N-monosubstituted 5-aminoderivatives 8 appeared to be more potent anti-inflammatory agents than the corresponding N,N-disubstituted 9, whereas these latter compounds exhibited higher analgesic activity.

Aerial oxidation of the quadruply bonded Mo-2(OAc)(4) in the presence of HprNP (2-(2-pyrrolyl)-1,8-naphthyridine) in CH2Cl2 provide the dinuclear oxochloromolybdate [Mo2O2Cl2(mu(2)-O)(2)(HprNP)(2)] (1). The molecular structure of 1 consists of the [Mo2O2Cl2(mu(2)-O)(2)] core with the cisoid Mo=O bonds and each HprNP ligand chelating the Mo center through the naphthyridine unit. An alternate route to access oxomolybdates is to employ quadruply bonded [Re2Cl8](2-) to oxidize cis-[Mo-2(pyNP)(2)(OAC)(2)][BF4](2) (pyNP = 2-(2-pyridyl)1,8-naphthyridine). The isolated compound is the tetranuclear molybdenum cluster [Mo4Cl5O8(pyNP)(2)] (2). The molecular formula of compound 2 is best described as [Mo2Cl3O2(mu(2)-O)(eta(3)-pyNP)][mu(3)-O][Mo2Cl2O2(mu(2)-O)(2)(eta(2) -pyNP)], the fusion of two oxochlorodimolybdates linked through a mu(3)-oxo linkage. The oxidation of the [Mo-coproduct equivalent to Mo-coproduct] unit to highly oxidized oxomolybdates and subsequent dimerization to tetranuclear core offers prospect for accessing new types of oxo-chloro-molybdenum clusters exhibiting interesting structural motifs.

Ultrasensitive aptamer biosensor for arsenic (III) detection based on label-free triple-helix molecular switch and fluorescence sensing platform

Arsenic ion is a well-known harmful heavy element widely existing in the environment. Arsenic pollution occurring frequently has become increasing a serious worldwide threat to human health and the environment. The development of sensitive and reliable methods to detect As3+ in water is of great importance to biochemical research and monitoring applications. Herein, a label-free fluorescence sensing platform was elaborately designed for As3+ monitoring using exonuclease III (Exo III)-assisted cascade target recycling amplification strategy. The triple-helix molecular switch was employed as the sensing element and 2-amino-5,6,7-trimethyl-1,8-naphthyridine was used as the signal indicator. The resulting biosensor is simple, ultrasensitive, and exhibits a limit of detection of 5 ng/L with high selectivity. Meanwhile, the proposed sensor is successfully applied to determination of As3+ in practical sample analysis (tap water, lake water and pond water). The results shown herein have important implications in the development of new fluorescent sensors for the fast, easy, and selective detection and quantification of As in water samples. More importantly, the proposed platform can be extended to detect other heavy metal ions with newly designed triple-helix molecular switch, as well as pesticide residue, antibiotic residues, and biomarkers by using aptamer sequences.

Identification of naphthyridine and quinoline derivatives as potential Nsp16-Nsp10 inhibitors: a pharmacoinformatics study

This research is a recent effort to explore some new heterocyclic compounds as novel and potential nonstructural protein-16-nonstructural protein-10 (Nsp16-Nsp10) inhibitors for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inhibition. The SARS-CoV-2 is causative agent of coronavirus disease 2019 (COVID-19) pandemic. A set of 58 molecules belongs to the naphthyridine and quinoline derivatives have been recently synthesized and considered for structure-based virtual screening against Nsp16-Nsp10. Molecular docking was virtually performed to screen for anti-SARS-CoV-2 activity against Nsp16-Nsp10. Fourteen out of fifty-eight compounds were exhibited binding affinity higher than co-crystal bound ligand s-adenosylmethionine (SAM) toward Nsp16-Nsp10. Further, the in silico pharmacokinetics assessment was carried out and it was found that two molecules possess the acceptable pharmacokinetic profile, hence considered promising Nsp16-Nsp10 inhibitors. The binding interaction analysis was revealed some crucial binding interactions between the final selected two molecules and ligand-binding amino acid residues of Nsp16-Nsp10 protein. In order to explore the characteristics of the protein-ligand complex and how selected small molecules retained inside the receptor cavity in dynamic states, all-atoms conventional molecular dynamics (MD) simulation was performed. Several factors were obtained from the MD simulation trajectory evidently suggested the potentiality of the molecules and stability of the protein-ligand complex. Finally, the binding affinity of both molecules and SAM was explored through the MM-GBSA approach which explained that both molecules possess strong affection towards the Nsp16-Nsp10. Hence, from the pharmacoinformatics assessment, it can be concluded that both heterocyclic compounds might be crucial for SARS-CoV-2 inhibition, subjected to experimental validation.
