Fluoroquinolones are synthetic antibacterial agents that stabilize the ternary complex of prokaryotic topoisomerase II enzymes (gyrase and Topo IV), leading to extensive DNA fragmentation and bacteria death. Despite the similar structural folds within the critical regions of prokaryotic and eukaryotic topoisomerases, clinically relevant fluoroquinolones display a remarkable selectivity for prokaryotic topoisomerase II, with excellent safety records in humans. Typical agents that target human topoisomerases (such as etoposide, doxorubicin and mitoxantrone) are associated with significant toxicities and secondary malignancies, whereas clinically relevant fluoroquinolones are not known to exhibit such propensities. Although many fluoroquinolones have been shown to display topoisomerase-independent antiproliferative effects against various human cancer cells, those that are significantly active against eukaryotic topoisomerase show the same DNA damaging properties as other topoisomerase poisons. Empirical models also show that fluoroquinolones mediate some unique immunomodulatory activities of suppressing pro-inflammatory cytokines and super-inducing interleukin-2. This article reviews the extended roles of fluoroquinolones and their prospects as lead for the unmet needs of small and safe multimodal-targeting drug scaffolds.

The addition of secondary amines to (2-chloropyridin-3-yl)(2-isothiocyanatophenyl)methanone, derived from 2-chloropyridine and N-(2-formylphenyl)formamide, followed by treatment of the resulting thiourea intermediates with sodium hydride has proven to provide a method for the synthesis of N,N-dialky1-5-oxobenzo[b][1,8]naphthyridine-10 (5H)-carbothioamides.

We report here a fully organic, self-assembled dimeric receptor, constructed from acyclic naphthyridyl-polypyrrolic building blocks. The cagelike dimer is stable in the solid state, in solution, and in gas phase, as inferred from X-ray diffraction and spectroscopic analyses. This system acts as a receptor for oxalic acid, maleic acid, and malonic acid in the solid state and in THF solution. In contrast, acetic acid, propionic acid, adipic acid, and succinic acid, with pK(a) values > ca. 2.8, were not bound effectively within the cagelike cavity. It is speculated that oxalic acid, maleic acid, and malonic acid serve to protonate the naphthyridine moieties of the host, which then favors binding of the corresponding carboxylate anions via hydrogen-bonding to the pyrrolic NH protons. The present naphthyridine- polypyrrole dimer is stable under acidic conditions, including in the presence of 100 equiv trifluoroacetic acid (TFA), p-toluenesulfonic acid (PTSA), H2SO4, and HCI. However, disassembly may be achieved by exposure to tetrabutylammonium fluoride (TBAF). Washing with water then regenerates the cage. This process of assembly and disassembly could be repeated >20 times with little evidence of degradation. The reversible nature of the present system, coupled with its dicarboxylic acid recognition features, leads us to suggest it could have a role to play in effecting the controlled capture and release of biologically relevant dicarboxylic acids.

Ruthenium arene complexes, [(eta(6)-p-cymene)(2)Ru-2(L)Cl-2](PF6)(2) [3b, L – 2, 7-bis(di-2-pyridinyl)-1,8-naphthyridine] and [(eta(6)-p-cymene) Ru(L’)Cl](PF6) [4, L’ = tri(2-pyridinyl)amine], were synthesized and characterized by spectroscopic and analytical techniques. The molecular structure of [(eta(6)-p-cymene) 2Ru2(L)Cl2]Cl-2 (3a) was further determined by single-crystal X-ray analysis. The use of these ruthenium complexes as pre-catalysts for oxidative coupling of 1,2-diols/1,2-aminoalcohol with o-phenylenediamines leading to quinoxalines was investigated.

With the ever-increasing concerns on environmental pollution and energy crisis, it is of great urgency to develop high-performance photocatalyst to eliminate organic pollutants from wastewater and produce hydrogen via water splitting. Herein, a polypyridyl-based mixed covalent Cu-I/II complex with triangular {Cu-3} and rhombic {Cu2Cl4} subunits alternately extended by mixed SCN- and Cl- heterobridges [Cu-4(DNP)(SCN)Cl-4](n) (1) [DNP = 2,6-bis(1,8-naphthyridine-2-yl)pyridine] was solvothermally synthesized and employed as a dual-functional co-photocatalyst. Resulting from a narrowed band-gap of 1.07 eV with suitable redox potential and unsaturated Cu-I/II sites, the complex together with H2O2 can effectively degrade Rhodamine B and methyl orange up to 87.4 and 88.2%, respectively. Meanwhile, the complex mixed with H2PtCl6 can also accelerate the photocatalytic water splitting in the absence of a photosensitizer with the hydrogen production rate of 27.5 mu mol.g(-1).h(-1). These interesting findings may provide informative hints for the design of the multiple responsive photocatalysts.

Iodine-catalyzed synthesis of dibenzo[b,h][1,6]-naphthyridine-11-carboxamides via a domino reaction involving double elimination of hydrogen bromide

An iodine-catalyzed reaction of 2-aminobenzamides and mucobromic acid was described and utilized to synthesize a variety of 6-oxo-5,6-dihydrodibenzo[b,h][1,6] naphthyridine-11-carboxamide derivatives in refluxing THF. As the two bromine atoms in mucobromic acid were found missing in the dibenzo-naphthyridine products, a domino-type reaction mechanism involving a double elimination of hydrogen bromide was proposed.
