A range of fluorine and naphthyridine based half-sandwich iridium (III) and ruthenium (II) complexes were synthesized. The iridium complexes possessed excellent antiproliferative properties, a substantial improvement over cisplatin, especially the best 1C containing the fluorine atom and 2C containing the naphthyridine. On the contrary, the ruthenium complexes displayed much less antiproliferative activity. Two X-ray crystal structures were determined. The cytotoxicity of the complexes can be changed flexible by regulating the metal center and the ancillary ligands. The best complex 1C was chose to study further on the mechanism of action. The chemical reactivity such as hydrolysis, reaction with nucleobases, glutathione and catalytic conversion of NADH to NAD(+), were investigated. Complex 1C can react with 9-ethylguanine (9-EtG) and catalyze oxidation of NADH. In addition, the self-luminescence of the complex 1C was also successfully used in confocal microscopy images for elucidating the subcellular localization. Complex 1C specifically targeted to lysosomes in A549 cancer cells and caused lysosomal damages and promote cathepsin B released. Flow cytometry studies confirmed that the biological effects of this type of complexes induced apoptosis, especially late apoptosis. Our results suggested that changes in the mitochondria membrane potential were responsible for apoptosis. The chemistry and biological studies has showed that this class of metal complexes are worthy of further exploration for the design of novel anticancer drugs. (C) 2018 Elsevier Masson SAS.

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.

The precursors N-(4-methylquinolin-2-yl) acetamide derivatives were effectively prepared in a single step from 2-aminoquinoline and acetic anhydride in presence of Amberlite-120A cation exchange catalyst under microwave irradiation. Condensation of 3a-d, with thioglycolic acid under microwave irradiation using anhydrous potassium carbonate as catalyst afforded thieno[2,3-b]benzo[1,8]naphthyridine-2-carboxylic acids (TBNCS) 4a-g. Elemental analysis, IR, H-1 NMR, and mass spectral studies were used to characterize these compounds. The interaction of thieno[2,3-b] benzo[1,8]naphthyridine-2-carboxylic acid (TBNC)(4a) with CT-DNA was studied by UV-Vis, viscosity as well as thermal denaturation methods. On binding to DNA, the absorption spectrum underwent bathochromic and hypochromic shifts. Binding parameters, determined from spectrophotometeric measurements indicated a binding constant of 1.8 X 10(6) M-1. The thieno[2,3-b]benzo[1,8] naphthyridine-2-carboxylic acid (4a) increases the viscosity of sonicated rod- like DNA fragments. The binding of TBNC to DNA increased the melting temperature by about 4 degrees C. DNA interaction studies suggest that (4a) binds to calf thymus DNA (CT-DNA).

The emergence of bacterial resistance against life-saving medicines has forced the scientific community and pharmaceutical industry to take actions in the quest for novel antibacterials. These should not only overcome the existing bacterial resistance but also provide at least interim effective protection against emerging bacterial infections. Research into DNA gyrase and topoisomerase IV inhibitors has become a particular focus, with the description of a new class of bacterial topoisomerase type II inhibitors known as novel bacterial topoisomerase inhibitors, NBTIs. Elucidation of the key structural modifications incorporated into these inhibitors and the impact these can have on their general physicochemical properties are detailed in this review. This defines novel bacterial topoisomerase inhibitors with promising antibacterial activities and potencies, which thus represent one potential example of the future drugs for bad bugs, as identified by the World Health Organization.
