Now introduce a scientific discovery about this category, Category: naphthyridines.

Oxazoline and camphor-pyrazole units are introduced on the 1,8-naphthyridine scaffold to access chiral ligands L-1, L-2 and L-3. Metalation of these chiral ligands with Cu(I) and Ag(I) precursors afforded di- and tetranuclear complexes [Cu4I4(L-1)(2)] (1), [Cu4I4(L-2)(2)] (2), [Cu2I2(L-3)] (3), [Cu2I(L-2)(2)](OTf) (4), [Ag-2(L-1)(2)](OTf)(2) (5) and [Ag-4(L-2)(4)Br](OTf)(3) (6), containing [M4Xn] (n= 1,4 and X = Br, I) or [M2Xn] (n = 0, 1, 2 and X = I) core. All complexes are structurally characterized. Naphthyridine-derived ligands reveal bridge-chelate coordination motif and hold two metal centers in close proximity. The tetranuclear complexes are dimer of dinuclear complexes bridged by the halides. Electronic absorption and emission spectra of copper complexes are reported. Catalytic utility of all complexes are examined for asymmetric transformations but they showed poor activity probably due to limited solubility and coordinative saturation at the metal centers. The best results are obtained with [L-3/Cu salt] combination for cyclopropanation of styrene, N-H bond insertion and nitroaldol (Henry) reactions with very low enantioselectivity.

A facile one pot multicomponent synthesis of 1,8-naphthyridinone derivatives was developed using a mild and reusable phosphotungstic acid catalyst. A 2-amino picoline, benzaldehyde derivatives and 1,3-dicarbonyl cyclohexane were used to synthesize 1,8-naphthyridinones, which was achieved by conventional heating under solvent-free conditions. All synthesized compounds were characterized by spectral analysis and screened for anticancer activity against A549 lung cancer cells. The results from the cell viability assay showed that the synthesized compounds do have a biological effect at various concentrations on the lung cancer cells. Compounds 4F-p-CF3 and 4H-VAN showed potential as an antiproliferative agent and a dose-dependent decline in cell viability was observed.

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.

Thiazinanes and its isomeric forms represent one of the most important heterocyclic compounds, and their derivatives represented a highly potent drug in disease treatment such as, 1,1-dioxido-1,2-thiazinan-1,6-naphthyridine, which has been shown to have anti-HIV activity by a mechanism that should work as anti-AIDS treatment, while (Z)-methyl 3-(naphthalen-1-ylimino)- 2-thia-4-azaspiro[5 5]undecane-4-carbodithioate showed analgesic activity, cephradine was used as antibiotic and chlormezanone was utilized as anticoagulants. All publications were interested in the chemistry of thiazine (partially or fully unsaturated heterocyclic six-membered ring containing nitrogen and sulfur), but no one was dealing with thiazinane itself which encouraged us to shed new light on these interesting heterocycles. This review was focused on the synthetic approaches of thiazinane derivatives and their chemical reactivity.

Background: Antimicrobial resistance is found in all microorganisms and has become one of the biggest threats to global health. New antimicrobials with different action mechanisms are effective weapons to fight against antibiotic-resistance. Objective: This review aims to find potential drugs which can be further developed into clinic practice and provide clues for developing more effective antimicrobials. Methods: DNA replication universally exists in all living organisms and is a complicated process in which multiple enzymes are involved in. Enzymes in bacterial DNA replication of initiation and elongation phases bring abundant targets for antimicrobial development as they are conserved and indispensable. In this review, enzyme inhibitors of DNA helicase. DNA primase, topoisomerases, DNA polymerase and DNA ligase were discussed. Special attentions were paid to structures, activities and action modes of these enzyme inhibitors. Results: Among these enzymes, type II topoisomerase is the most validated target with abundantinhibitors. For type II topoisomerase inhibitors (excluding quinolones), NBTIs and benzimidazole urea derivatives are the most promising inhibitors because of their good antimicrobial activity and physicochemical properties. Simultaneously, DNA gyrase targeted drugs are particularly attractive in the treatment of tuberculosis as DNA gyrase is the sole type II topoisomerase in Mycobacterium tuberculosis. Relatively, exploitation of antimicrobial inhibitors of the other DNA replication enzymes are primeval, in which inhibitors of topo III are even blank so far. Conclusion: This review demonstrates that inhibitors of DNA replication enzymes are abundant, diverse and promising, many of which can he developed into antimicrobials to deal with antibiotic resistance.
