A series of N-substituted 1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylate esters has been prepared in two steps from ethyl 2-(2-chloronicotinoyl)acetate. Treatment of the beta-ketoester with N,N-dimethylformamide dimethyl acetal in N,N-dimethylformamide (DMF) gave a 95% yield of the 2-dimethylaminomethylene derivative. Subsequent reaction of this beta-enaminone with primary amines in DMF at 120oC for 24 h then afforded the target compounds in 4782% yields by a tandem SNAr-addition-elimination reaction. Synthetic and procedural details as well as a mechanistic rationale are presented.

Two naphthyridine-based receptors have been designed and synthesised for biotin salt. The compounds serve as good hosts for the detection of biotin carboxylate rather than biotin ester. The correct dispositions of the binding groups under an isophthaloyl spacer enable the receptors to bind both the cyclic urea and the carboxylate ends simultaneously with moderate binding constant values. The receptors are effective for the binding of tetrabutylammonium salt of biotin with a concomitant increase in the fluorescence of naphthyridine and show appreciable binding of biotin salt in CH3CN containing 1.2% DMSO. The binding was monitored in CH3CN containing 1.2% DMSO and DMSO using H-1 NMR, UV-vis and fluorescence spectroscopic methods.

The asymmetric unit of the title compound, [RuCl2(C13H9N3)-(CO)(2)], consists of four crystallographically independent Ru-II complexes. Each RuII atom is in a distorted octahedral environment coordinated by two carbonyl ligands, two Cl atoms and a chelating 2-(2-pyridyl)-1,8-naphthyridine (pynp) ligand. The carbonyl ligands are cis to each other, while the Cl atoms are trans. Relatively short interatomic distances (2.60-2.67 angstrom) between the uncoordinated N atom of pynp and the C atom of the carbonyl imply a donor-acceptor interaction between the pynp and carbonyl ligands.

We report the synthesis of the azaoxoaporphine alkaloid sampangine (4) and a series of ring A analogues and isomers of the marine pyridoacridine alkaloid ascididemin (2). This approach starts from readily available 1-bromo[2,7] naphthyridine (12) or 4-bromobenzo[c][2,7] naphthyridine (5), and the ring A scaffold bearing an ester moiety is introduced by a Suzuki or Negishi cross-coupling reaction. The final cyclization step was achieved through a directed remote ring metallation with the Knochel-Hauser base (TMPMgCl center dot LiCl; TMP = 2,2,6,6-tetramethylpiperidinyl), followed by intramolecular trapping of the ester group.

Cyclometalation on the substituted imidazo[1,2-a][1,8]naphthyridine platform involves either the C-3-aryl or C-4′-aryl ortho carbon and the imidazo nitrogen N-3′. The higher donor strength of the imidazo nitrogen in comparison to that of the naphthyridine nitrogen aids regioselective orthometalation at the C-3/C-4′-aryl ring with Cp*Ir-III (Cp* = eta(5)-pentamethylcyclopentadienyl). A longer reaction time led to double cyclometalations at C-3-aryl and imidazo C-5′-H, creating six- and five-membered metallacycles on a single skeleton. Mixed-metal Ir/Sn compounds are accessed by insertion of SnCl2 into the Ir-Cl bond. Pd(OAc)(2) afforded an acetate-bridged dinuclear ortho-metalated product involving the C-3-aryl unit. Metalation at the imidazo carbon (C-5′) was achieved via an oxidative route in the reaction of the bromo derivative with the Pd(0) precursor Pd-2(dba)(3) (dba = dibenzylideneacetone). Regioselective C-H/Br activation on a rigid and planar imidazonaphthyridine platform is described in this work.

GlaxoSmithKline and Astex Pharmaceuticals recently disclosed the discovery of the potent H-PGDS inhibitor GSK2894631A la (IC50 = 9.9 nM) as part of a fragment-based drug discovery collaboration with Astex Pharmaceuticals. This molecule exhibited good murine pharmacokinetics, allowing it to be utilized to explore H-PGDS pharmacology in vivo. Yet, with prolonged dosing at higher concentrations, la induced CNS toxicity. Looking to attenuate brain penetration in this series, aza-quinolines, were prepared with the intent of increasing polar surface area. Nitrogen substitutions at the 6- and 8-positions of the quinoline were discovered to be tolerated by the enzyme. Subsequent structure activity studies in these aza-quinoline scaffolds led to the identification of 1,8-naphthyridine 1y (IC50 = 9.4 nM) as a potent peripherally restricted H-PGDS inhibitor. Compound 1y is efficacious in four in vivo inflammatory models and exhibits no CNS toxicity.

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.
