A series of new DNA binding molecules NCD-Cn-SH (n = 3, 4, 5, and 6) is reported, which possesses the NCD (naphthyridine carbamate dimer) domain selectively binding to the G-G mismatch in the 5′-CGG-3’/5′-CGG-3′ sequence and a thiol moiety, which undergoes spontaneous dimerization to (NCD-Cn-S)(2) upon oxidation under aerobic conditions. The S-S dimer (NCD-Cn-S)(2) produced the 1:1 binding complex with improved thermal stability. The dimer binding to the CGG/CGG DNA showed higher positive cooperarivity than the binding of monomer and previously synthesized NCTn derivative. The dimerization of NCD-Cn-SH was selectively accelerated on the CGG repeat DNA but not on the CAG repeat DNA.

Many methods to prepare heterocyclic compounds involve toxic solvents and reagents. There is therefore a need to design cleaner synthetic procedures. 1,6-Naphthyridine derivatives are used in many applications such as cancer chemotherapy, antibacterials, antivirals and antiproliferatives. Here, we report the solvent-free and catalyst-free synthesis of 1,6-naphthyridine derivatives. Synthesis is done by grinding of 2 mmol of ketones, 2 mmol of malononitrile and 1 mmol of amines in a mortar at room temperature for 5-7 min. 1,2-Dihydro[1,6]-naphthyridine derivatives were obtained in 90-97 % yields.

The 1,8-naphthyridine CR80 (ethyl 5-amino-2-methyl-6,7,8,9-tetrahydrobenzo[b] [1,8] naphthyridine3- carboxylate) has shown interesting neuroprotective properties in in vitro and in vivo models of neurodegeneration. In spite of these promising outcomes, the molecular and cellular mechanisms underlying CR80 actions need to be further explored. Materials & methods: We herein report the signal transduction pathways involved in developmental, neuroprotective and stress-activated processes, as well as the gene expression regulation by CR80 in SH-SY5Y neuroblastoma cells. Results: The CR80 exposure upregulated several antioxidant enzymes (HO-1, GSR, SQSTM1, and TRXR1) and anti-apoptotic proteins (Bcl-xL, Bcl-2, P21, and Wnt6). Conclusion: The observed changes in gene expression would afford new insights on the neuroprotective profile of CR80.

Fifty-one 1-(cyclopropyl/tert-butyl/4-fluorophenyl)-1,4-dihydro-6-nitro-4-oxo-7-(substituted secondary amino)-1,8-naphthyridine-3-carboxylic acids were synthesized and evaluated for antimycobacterial in vitro and in vivo against Mycobacterium tuberculosis H37Rv (MTB), multi-drug-resistant Mycobacterium tuberculosis (MDR-TB) and Mycobacterium smegmatis (MC2) and also tested for the ability to inhibit the supercoiling activity of DNA gyrase from M. smegmatis. Among the synthesized compounds, 1-tert-butyl-1,4-dihydro-7-(4,4-dimethyloxazolidin-3-yl)-6-nitro-4-oxo-1,8-naphthyridine-3-carboxylic acid (10q) was found to be the most active compound in vitro with an MIC of 0.1 mu M against MTB and MDR-TB and was 3 and 455 times more potent than isoniazid against MTB and MDR-TB, respectively. In the in vivo animal model 10q decreased the bacterial load in lung and spleen tissues with 2.39 and 3.89-log 10protections respectively at the dose of 50 mg/kg body weight.

The electronic structures and photophysical properties of six isomeric Ir(III) complexes with different N-heterocyclic naphthyridine ligands were investigated by density functional theory (DFT) and time dependent DFT (TD-DFT) approach. The radiative transition rates (k(r)) were determined through calculated the spin-orbital coupling (SOC) matrix elementsh < T-m vertical bar H-SOC vertical bar S-n > and the energy levels (E-Sn and E-Tm). The non-radiative transition rates (k(nr)) were estimated through analysis of the structural distortions, the d-orbital splittings and the energy differences between the S-0 and T-1 states Delta E(T-1 – S-0). As the results, the E-Sn, the E-Tm and the energy splittings (Delta ES1-Tm and Delta ETm-Tm-1) can be regulated by the position of two nitrogen atoms in naphthyridine ring for studied complexes. Moreover, Ir(III) complex inclusive of quinoxaline heterocyclic ring presents large k(r) and k(nr), so its phosphorescence quantum efficiency is difficult up to be 100%. While two Ir(III) complexes bound to quinazoline heterocyclic ring show weakly emissive because of large k(nr). Notably, the presence of the cinnoline heterocyclic ring in the Ir(III) complex makes singlet-triplet intersystem (ISC) rate and k(r) fast but k(nr) slow, then leads to its high phosphorescence quantum efficiency.

C-H amination reactions are valuable transformations for the construction of C-N bonds. Due to their relatively high bond dissociation energies, C(sp(2))-H bonds are generally not susceptible toward direct nitrene insertion, necessitating alternative mechanisms for C-H activation. Here, we report that cationic dinuclear (NDI)Ni-2 (NDI = naphthyridine-diimine complexes catalyze intramolecular nitrene insertions into aryl and vinyl C(sp(2))-H bonds. Mechanistic studies suggest that a bridging imido ligand supported at a Ni-2 site induces C-H activation by a 1,2-addition pathway to generate an azametallacyclic intermediate. This organometallic mechanism contrasts with the electrocyclization/1,2-shift mechanism proposed for analogous transformations using Rh-2 catalysts. The implications of these mechanistic differences for the stereoselectivity and chemoselectivity of C-H amination are described.

Synthesis of the Azaoxoaporphine Alkaloid Sampangine and Ascididemin-Type Pyridoacridines through TMPMgCl center dot LiCl-Mediated Ring Closure

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.

A New 4-phenyl-1,8-naphthyridine Derivative Affects Carcinoma Cell Proliferation by Impairing Cell Cycle Progression and Inducing Apoptosis

In targeted cancer therapy the search for novel molecules led to the discovery of a plethora of small organic molecules inhibiting cancer cell proliferation. Among these, quinazoline and derivatives, such as quinolines and naphthyridines, have been considered as of particular interest. One of these, the naphthyridine derivative 4-phenyl-2,7-di(piperazin-1-yl)-1,8-naphthyridine, has been analyzed in detail in the present work. We found that this compound elicited a powerful anti-proliferative activity on carcinoma cells, with IC50 values comparable with paradigmatic microtubule-deranging drugs. The mechanisms underlying this effect were seemingly due to a framework of cellular alterations that include peculiar alterations of mitochondria, i.e. an increase of mitochondrial membrane potential (MMP), followed by the typical MMP loss leading to the release of apoptogenic factors, and cell death by apoptosis. Furthermore, the analysis of cell cycle revealed that a significant percentage of treated cells was in G2/M phase. This block was seemingly due to a target effect of the naphthyridine derivative on microtubular network dynamic instability, which impaired mitotic spindle formation, possibly leading to mitotic catastrophy. Since the dual effects of naphthyridine derivative on cell cycle and mitotic spindle were obtained at very low concentrations, i.e. micromolar concentrations, we hypothesize that this compound could represent a new promising tool in the control of cancer cell proliferation.
